Image slide show using wcm web content viwer portlet

Step 1 :- Please refer to my previous blog on slide show using query. I will be using mockup and files from that post.

Step 2 :- We will go step by step first create a presentation template as given below. Then put the asp content given in my previous blog post.

Step 3 :- Now create components for css ,js files and include them in presentation template.

Now click on style sheet and add style sheet name

Now click browse and add css files to it

Now select and save the file

Now click on save and close

Similarly do it for other css files

Step 4 :- Now try to create file resources for java script files

Now click on file resource and add give a name to it

Click browse and add javascript file

Now click on save and close

Do the same for other js files also

Step 5 :- Now we have to map all these components in presentation template. Now navigate to presentation template and then click on insert a tag

Now in select a topic drop down select component reference

Now click on library component and then add the css component

Now select a component and similarly do it for all css. Then you will get below refernces.

Step 6 :- Now we have to place those references in correct places like below.

[Component id="958a42c8-14cd-41ea-9d78-4286ace9da19:NC9yaXZlcmJlbmR0ZWFtIGNvbnRlbnQvc2xpZGUgc2hvdyBmaWxlcy9wZ3dzbGlkZXNob3cubWlu" name="riverbendteam content/slide show files/pgwslideshow.min"]

[Component id="97e98fb2-c58b-4f2c-982d-05a22fa91979:NC9yaXZlcmJlbmR0ZWFtIGNvbnRlbnQvc2xpZGUgc2hvdyBmaWxlcy9wZ3dzbGlkZXNob3dfbGlnaHQ=" name="riverbendteam content/slide show files/pgwslideshow_light"]

[Component id="6580c146-a53b-402b-bcbf-22d4676adb95:NC9yaXZlcmJlbmR0ZWFtIGNvbnRlbnQvc2xpZGUgc2hvdyBmaWxlcy9wZ3dzbGlkZXNob3dfbGlnaHQubWlu" name="riverbendteam content/slide show files/pgwslideshow_light.min"]

$(document).ready(function() {

$('.pgwSlideshow').pgwSlideshow();

});

</script>

Step 7 :- Now we have to create a Authoring template and map above presentation template

Step 8 :- Now we have to draw outline of components in Authoring template so click on manage elements and add two image components as given below

Add second image component to authoring template

Now see at the bottom we have two image components outlined to AT

Step 9 :- Now we have to create a site area to hold the content which will be mapped to AT

Step 10 :- Go inside the site area and create a content by selecting previously created Authoring template

Now upload images to both image components

Now select the workflow and select express workflow as default workflow

Step 11 :- Now save and close above content item and the open presentation template and then click on insert element tags and then insert Authoring template.

Now click on save. Finally our presentation show appear like below

[Component id="958a42c8-14cd-41ea-9d78-4286ace9da19:NC9yaXZlcmJlbmR0ZWFtIGNvbnRlbnQvc2xpZGUgc2hvdyBmaWxlcy9wZ3dzbGlkZXNob3cubWlu" name="riverbendteam content/slide show files/pgwslideshow.min"]

[Component id="97e98fb2-c58b-4f2c-982d-05a22fa91979:NC9yaXZlcmJlbmR0ZWFtIGNvbnRlbnQvc2xpZGUgc2hvdyBmaWxlcy9wZ3dzbGlkZXNob3dfbGlnaHQ=" name="riverbendteam content/slide show files/pgwslideshow_light"]

$(document).ready(function() {

$('.pgwSlideshow').pgwSlideshow();

});

</script>

<li>[Element context="current" type="content" key="img1"]</li>

<li>[Element context="current" type="content" key="img2"]</li>

</ul>

Step 12 :- Now you can preview then select a site area previously created and then preview it. You can see slide show.

Now click on ok you can see slide show

Jquery slide show in web application

Step1 :- Navigate to this url https://github.com/Pagawa/PgwSlideshow and then click on download zip at the right end bottom.

Step2 :- Now create a dynamic web project and place the css and js files like below.

Step 3 :- Add some images as given above under images page. Then create a SlideShow.jsp under asp folder and paste below content.

<!DOCTYPE HTML><%@page language="java"

 contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

<html>

<head>

<title>SlideShow</title>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

  <link href="css/pgwslideshow_light.css" rel="stylesheet" type="text/css">

 <script type="text/javascript" src="js/pgwslideshow.js" ></script>

 <script type="text/javascript" src="js/pgwslideshow.min.js" ></script>

 <script type="text/javascript">

     $(document).ready(function() {

    $('.pgwSlideshow').pgwSlideshow();

});

 </script>

</head>

<body>

<ul class="pgwSlideshow">

    <li><img src="images/rio.jpg" alt="Rio de Janeiro, Brazil"></li>

</ul>

</body>

</html>

Step 4 :- Now run it on server you will be able to see slide show

Step 5 :- Best works in chrome,firefox

Performance in personalization websphere portal

In order to improve the performance of the personalization (PzN) function in WebSphere Portal, the PzN results can be cached. Otherwise the LDAP and the Portal database is accessed excessively. There are different forms of caching within PZN - resource collection caches, visibility rule caches, and others. However, most are surprised to find that Portal disables the PzN visbility cache by default.

If your production (or performance sensative) Portal uses PzN, then you should definitely enable the PzN cache. If not, both the LDAP and the database are excessively accessed. Note that visability rules in the theme use PzN.

The cache is enabled via a file. There is one of these files per node. Therefore, you must update one file on every node and then restart the cluster for the change to take effect.

The file is /opt/IBM/WebSphere/wp_profile/PortalServer/config/config/services/PersonalizationService.properties.

Set the property "rulesEngine.attributeBasedAdmin.enableCaching" equal to "true". This will enable the Portal PzN caching in Portal.

In addition, there is an undocumented property "rulesEngine.user.nestedGroupLookup" which can be set to false to speed up PzN. However, this should only be done if (and only if) nested groups are NOT used in the authorization ACL lists in Portal.

Personilization in websphere portal

Personalization :- Using this we can hide a page or a portlet depending upon user group,access role,geographic location or browser used by him.

Use-case :- If user belong to particular to group do not show the portlet.

Step 1 :- Login to portal administration then navigate to application,personalization and then to business rules.

Step 2 :- Now click on new drop down and then click on rule and fill below details

Step 3 :- Now select the Rule Type as Visibility rule as given below

Step 4 :- Now you can add any attribute based on your use case. I will be adding user info groups here. Because my visibility rule is based upon the group user belongs to.

Step 5 :- Now select the value of group by which you will determine. Whether to show a portlet or page. Now click value and then find groups then select your group.

Step 6 :- Now click on save and then navigate to preview to verify the rule is working or not. For me wpsadmin falls under wpsadmins group. So it show me output as show.

Step 7 :- Now navigate to portlets in administration while adding a portlet to portal page. Click on show portlet rule mappings and the select the rule to the portlet and then click on save.

Scenario 3: Find content by various criteria
To find content by Authoring Template, Category, path, Workflow Stage, modified since date, and modified between dates, you can select and use the appropriate API code in listing 3, which uses the following APIs:
workspace.findContentByAuthoringTemplate
workspace.findContentByCategory
workspace.findContentByPath
workspace.findContentByWorkflowStage
workspace.findContentModifiedSince

Scenario 4: Search for content based on Authoring Template, Site Area, Category, and Keywords criteria
To search for content based on criteria that are a combination of Authoring Template, Site Area, Category, or Keywords, you can select and use the appropriate API code in listing 4. You can do this by using the ContentSearch method, which returns an iterator of IDs of objects that match the given search criteria.
The ContentSearch method behaves in a manner similar to the Menu Component. If Site Areas have been specified, then all the ancestor and descendant Site Areas are also included in the search.
This performs an "or" search, not an "and" search. This means that a search for two different Categories and a Content Template will return content profiled with at least one of each profile type (one Category and one Template), not just content that matches all the parameters. Content that matches only one criteria type (Template only) will not be returned.

Note that the order of results is not guaranteed, and all parameters are optional except matchAllKeys, the last parameter.

Listing 4. Example code to search for content by criteria
<%@ page import="com.ibm.workplace.wcm.api.*"%>
<%@ page import="java.util.*"%>
<%
// retrieve repository
Repository repository = WCM_API.getRepository();
// get workspace for current user
Workspace workspace = repository.getWorkspace(request.getUserPrincipal());
// Set library
workspace.setCurrentDocumentLibrary(workspace.getDocumentLibrary("WebContent"));
DocumentId contentId = null;
DocumentId authoringTemplateId = null;
DocumentId siteAreaId = null;
DocumentId categoryId = null;
// define authoring template
String authoringTemplateName = new String("AuthoringTemplate");
// find authoring template by name
DocumentIdIterator authoringTemplateIterator = workspace.findByName(DocumentTypes.AuthoringTemplate,authoringTemplateName);
if (authoringTemplateIterator.hasNext()){
authoringTemplateId = authoringTemplateIterator.nextId();
out.println("Authoring Template found : " + authoringTemplateName + " ");
}else {
out.println("Could not find Authoring Template: " + authoringTemplateName + " ");
}
// define siteare
String siteArea = new String("SiteArea");
// find sitearea by name
DocumentIdIterator siteAreaIterator = workspace.findByName(DocumentTypes.SiteArea,siteArea);
if (siteAreaIterator.hasNext()){
siteAreaId = siteAreaIterator.nextId();
out.println("Sitearea Found : " + siteArea + " ");
}else {
out.println("Could not find Sitearea : " + siteArea + " ");
}
// define category
String categoryName = new String("Category");
// find category by name
DocumentIdIterator categoryIterator = workspace.findByName(DocumentTypes.Category,categoryName);
if (categoryIterator.hasNext()){
categoryId = categoryIterator.nextId();
out.println("Category Found : " + categoryName + " ");
}else {
out.println("Could not find Category : " + categoryName + " ");
}
// define keywords
String[] keywords = new String[]{"Keyword"};
// search all the contents based on authoring template , sitearea , category and keywords
DocumentIdIterator contentIterator = workspace.contentSearch(authoringTemplateId, new DocumentId [] {siteAreaId}, new DocumentId [] {categoryId}, keywords,true);
if(contentIterator.hasNext()){
contentId = contentIterator.nextId();
while(contentId!=null)
{
out.println("Found Content : " + contentId.getName() + " ");
contentId = contentIterator.nextId();
}
} else {
out.println("Could not find any Content using the contentSearch Method");
}
%>

Scenario 5: Creating a new Site
You can create a new site using Web Content Management API methods, after which you can also use all the methods under Site Object once the site has been created. You can select and

use the appropriate code provided in listing 5, which demonstrates only the creation of a new site, setting its name, title, description, and then saving it to the repository.
We use workspace.createSite to achieve this, which returns the new Site object.

Listing 5. Example code to create a new Site

< %@ page import="com.ibm.workplace.wcm.api.*"%>
<%@ page import="java.util.*"%>
<%
// retrieve repository
Repository repository = WCM_API.getRepository();
// get workspace for current user
Workspace workspace = repository.getWorkspace(request.getUserPrincipal());
// Set library
workspace.setCurrentDocumentLibrary(workspace.getDocumentLibrary("WebContent"));
// create new site
Site newSite = workspace.createSite();
newSite.setName("NewSite");
newSite.setTitle("NewSite");
newSite.setDescription("New Site Created using WCM API");
String[] saveMessage = workspace.save((Document)newSite);
if (saveMessage.length==0){
out.println("Could not create new Site.. ");
}else{
out.println("New Site created successfully.");
}
%>

Scenario 6: Creating a new Site Area
You can also create a new Site Area by using Web Content Management API methods, after which you can use all the methods under the Site Area Object.
Listing 6 demonstrates only creating a new Site Area, setting its name, title, description, and saving it to the repository. We use workspace.createSiteArea here, which creates a new Site
Area under the given parent. The parent can be a Site or a Site Area, and the method returns the new Site Area object.
Listing 6. Example code to create new Site Area
<%@ page import="com.ibm.workplace.wcm.api.*"%>
<%@ page import="java.util.*"%>
<%
// retrieve repository
Repository repository = WCM_API.getRepository();
// get workspace for current user
Workspace workspace = repository.getWorkspace(request.getUserPrincipal());
// Set library
workspace.setCurrentDocumentLibrary(workspace.getDocumentLibrary("WebContent"));
DocumentId documentId = null;
Site parentSite = null;
String parentSiteName = "Site";
DocumentId siblingId = null;
// find parent site
DocumentIdIterator siteIterator = workspace.findByName(DocumentTypes.Site,parentSiteName);
if (siteIterator.hasNext()){
documentId = siteIterator.nextId();
parentSite = (Site) workspace.getById(documentId);
// create new sitearea
SiteArea newSiteArea = workspace.createSiteArea((DocumentId)parentSite.getId(),siblingId,ChildPosition.END);
newSiteArea.setName("NewSiteArea");
newSiteArea.setTitle("NewSiteArea");
newSiteArea.setDescription("New Sitearea Created using WCM API
String[] saveMessage = workspace.save((Document)newSiteArea);
if (saveMessage.length==0) {
out.println (" Created new Sitearea under " + parentSiteName );
}
} else {
out.println (" Could not find parent Site " + parentSiteName + ". Could not create a new Sitearea." );

}
%>

Scenario 7: Creating new Content
You can create new Content under a specific Site Area at a specific position, using a Web Content Management API. You can select and use the appropriate provided code in listing 7, which demonstrates the creation of Content under a specific Site Area at the last position, with a specific Authoring Template.
The code also configures the Workflow while saving the content. We use workspace.createContent for this purpose, which returns a new content object based on the specified Authoring Template. The API code can be changed based on your requirements.

Listing 7. Example code to create a new Content
<%@ page import="com.ibm.workplace.wcm.api.*"%>
<%@ page import="java.util.*"%>
<%
// retrieve repository
Repository repository = WCM_API.getRepository();
// get workspace for current user
Workspace workspace = repository.getWorkspace(request.getUserPrincipal());
// Set library
workspace.setCurrentDocumentLibrary(workspace.getDocumentLibrary("WebContent"));
// define authoring template
String authoringTemplateName = new String("AuthoringTemplate");
// define parent sitearea
String parentSiteAreaName = new String("SiteArea");
// define workflow
String workflowName = new String("Workflow");
DocumentId authoringTemplateId = null;
DocumentId parentSiteAreaId = null;
DocumentId siblingId = null;
DocumentId workflowId = null;
// find authoring template by name
DocumentIdIterator authoringTemplateIterator = workspace.findByName(DocumentTypes.AuthoringTemplate,authoringTemplateName);
if (authoringTemplateIterator.hasNext()){
authoringTemplateId = authoringTemplateIterator.nextId();
out.println("Authoring Template found : " + authoringTemplateName + " ");
}else {
out.println("Could not find Authoring Template: " + authoringTemplateName + " ");
}
// find sitearea by name
DocumentIdIterator siteAreaIterator = workspace.findByName(DocumentTypes.SiteArea,parentSiteAreaName );
if (siteAreaIterator.hasNext()){
parentSiteAreaId = siteAreaIterator.nextId();
out.println("Sitearea Found : " + parentSiteAreaName + " ");
}else {
out.println("Could not find Sitearea : " + parentSiteAreaName + " ");
}
// find workflow by name
DocumentIdIterator workflowIterator = workspace.findByName(DocumentTypes.Workflow,workflowName);
if (workflowIterator.hasNext()){
workflowId = workflowIterator.nextId();
out.println("Workflow found : " + workflowName + " ");
}else {
out.println("Could not find Workflow: " + workflowName + " ");
}
if((authoringTemplateId!=null) && (parentSiteAreaId!=null) && (workflowId!=null)){
// create new content
Content newContent = workspace.createContent(authoringTemplateId,parentSiteAreaId,siblingId,ChildPosition.END);
newContent.setName("NewContent");
newContent.setTitle("NewContent");
newContent.setDescription("New Content created using WCM API"); newContent.setWorkflowId(workflowId);
String[] saveMessage = workspace.save((Document)newContent);
if (saveMessage.length==0) {
out.println (" Created new Content under " + parentSiteAreaName );
}
}else {
out.println ("Could not create new content");
}
%>

Scenario 8: Creating a new Content Link that is linked to existing Content
You can create a new Content Link that is linked to existing Content under a specific Site Area. The Content must be saved before creating a link to it, while the Content Link is created immediately, and should not be saved.
We use workspace.createContentLink to achieve this, which returns a new Content Link object. The code in listing 8 assumes that the Content Link is not present under the Site Area.

Listing 8. Example code to create a new Content Link
<%@ page import="com.ibm.workplace.wcm.api.*"%>
<%@ page import="java.util.*"%>
<%
// retrieve repository
Repository repository = WCM_API.getRepository();
// get workspace for current user
Workspace workspace = repository.getWorkspace(request.getUserPrincipal());
// Set library
workspace.setCurrentDocumentLibrary(workspace.getDocumentLibrary("WebContent"));
// define content
String contentName = new String("Content");
// define sitearea where the content link needs to be created
String parentSiteArea = new String("NewSiteArea");
DocumentId contentId = null;
DocumentId parentSiteAreaId =null;
DocumentId siblingId = null;
// find content by name
DocumentIdIterator contentIterator = workspace.findByName(DocumentTypes.Content,contentName);
if (contentIterator.hasNext())
contentId = contentIterator.nextId();
// find sitearea by name
DocumentIdIterator parentSiteAreaIterator = workspace.findByName(DocumentTypes.SiteArea,parentSiteArea);
if (parentSiteAreaIterator.hasNext())
parentSiteAreaId = parentSiteAreaIterator.nextId();
if((contentId!=null) && (parentSiteAreaId!=null)) {
// create content link
ContentLink contentLink = workspace.createContentLink(contentId,parentSiteAreaId,siblingId,ChildPosition.END);
out.println("New Content link of Content " + contentName + " is created under new Sitearea " + parentSiteArea);
} else{
out.println("Could not create Content link of Content " + contentName + " under new Sitearea " + parentSiteArea);
}
%>

Scenario 9: Creating various Library Components
You can create Library Components such as DateComponent, DocumentManagerComponent, FileComponent, HTMLComponent, ImageComponent, JSPComponent, LinkComponent, RichTextComponent, ShortTextComponent, TextComponent, UserSelectionComponent.
The code in listing 9 demonstrates only creation, setting the name, title, description, and then saving them in the Web Content Management repository. The code can be directly used to create a File Component, Image Component, and Rich Text Component:
workspace.createFileComponent
workspace.createImageComponent
workspace.createRichTextComponent
Other APIs can be used once the components are created.

Listing 9. Example code to create various library components
<%@ page import="com.ibm.workplace.wcm.api.*"%>
<%@ page import="java.util.*"%>
<%
// retrieve repository
Repository repository = WCM_API.getRepository();
// get workspace for current user
Workspace workspace = repository.getWorkspace(request.getUserPrincipal());
// Set library
workspace.setCurrentDocumentLibrary(workspace.getDocumentLibrary("WebContent"));
String[] saveMessage = new String[1];

// ***************** Create File Resource Component example ********************
LibraryFileComponent libraryFileComponent = workspace.createFileComponent();
libraryFileComponent.setName("NewFileComponent");
libraryFileComponent.setTitle("NewFileComponent");
libraryFileComponent.setDescription("New File resource component created using API");

Scenario 10: Creating a new Taxonomy and a new Category
You can create a new Taxonomy as well as a new Category under a specific Category or Taxonomy. The code in listing 10 demonstrates creating a new Taxonomy and new Category under a specific parent Taxonomy, and you can use this code directly in your code. We use:
workspace.createTaxonomy, which returns the new Taxonomy object
workspace.createCategory, which returns the new Category object

Scenario 11: Creating and canceling drafts on published Content items
You can create as well as cancel drafts on published content, using a Web Content Management API. The code in listing 11 can be used directly to create a draft of existing content and also to cancel an existing draft on published content.

Listing 11. Example code to create and cancel drafts
<%@ page import="com.ibm.workplace.wcm.api.*"%>
<%@ page import="java.util.*"%>
<%
// retrieve repository
Repository repository = WCM_API.getRepository();

Scenario 13: Render Sites, Site Areas, Contents, Content components, or Library Components
You can render Sites, Site Areas, Contents, Content components, or Library components. The given Web Content Management content component is rendered using the specified rendering context.
Note that it’s not enough to specify only the ContentComponent to be rendered; the path to the item containing the ContentComponent must also be specified in the RenderingContext.
The code in listing 13 demonstrates rendering Content, Content component, and the Library component. You can always add or remove more components per your requirements.

Scenario 16: Moving or copying non-hierarchical or root items to another library
To move or copy any non-hierarchical items (Authoring Templates, Presentation Templates, Library Components, Workflows, Workflow Stages), or root items (Sites and Taxonomies) to another library, use the code in listing 16. To move the item to another library, we use the workspace.moveToLibrary method, which moves non-hierarchical or root items to another library.
To copy the item, we use the workspace.copyToLibrary method to replace the workspace.moveToLibrary method, using the same code below.
The code in listing 16 shows how we can achieve this for Authoring Templates, Presentation Templates, Library components, Workflows, Workflow Stages, Sites, and Taxonomies.

Scenario 17: Moving or copying a Category within/between libraries
To move or copy a Category in the same library or between libraries, use the code in lisitng 17 below. To move the item in the same or to another library, we use the workspace.moveCategory method, which essentially moves a category and adds it under a new parent.
To copy the category, we use the workspace.copyCategory method to replace the workspace.moveToLibrary method, using the same code below.
Note that the example below moves a category to another taxonomy; you can also move the category to another parent category.

Scenario 18:
Deleting and purging Objects
We can delete and purge all types of objects, using Web Content Management APIs. It’s best to clear all the references of the object being deleted before deleting the actual object; otherwise, the deletion will fail.
We can also purge (permanently delete) the object from the repository. The code in listing 18 demonstrates deleting as well as purging a content item and as well as a Library Component.
To delete a Site / Site Area / Taxonomy, you must delete all the children prior to deleting the Sites / Site Areas / and Taxonomies.
