Introduction

You can develop an Adobe Experience Manager (AEM) OSGi bundle that uses the Jackrabbit UserManager APIs to perform AEM user operations. This API provides access to both AEM users and groups and is located in the org.apache.jackrabbit.api.security.user Java package. In this development article, a custom Sling Servlet is created that dynamically creates AEM users and groups.

For more information, see Interface UserManager.

The following illustration shows the AEM page that performs a POST operation to the AEM custom Sling Servlet that creates the user and group. 

NewUser

This development article guides you through creating an AEM application that creates AEM Groups and Users by using the Jackrabbit UserManager API. Application logic is implemented as an OSGi bundle that is built using Declarative Services (DS) and Maven. DS is used to inject a ResourceResolverFactory instance into the service. The OSGi bundle is a managed component, which means that the OSGi service container creates the ResourceResolverFactory instance.

Create an AEM application folder structure 

Create an AEM application folder structure that contains templates, components, and pages by using CRXDE Lite.

CQAppSetup

The following describes each application folder:

  • application name: contains all of the resources that an application uses. The resources can be templates, pages, components, and so on.
  • components: contains components that your application uses. 
  • page: contains page components. A page component is a script such as a JSP file. 
  • global: contains global components that your application uses.
  • template: contains templates on which you base page components. 
  • src: contains source code that comprises an OSGi component (this development article does not create an OSGi bundle using this folder). 
  • install: contains a compiled OSGi bundles container.

 

To create an AEM application folder structure:

  1. To view the CQ welcome page, enter the URL http://[host name]:[port] into a web browser. For example, http://localhost:4502.
  2. Select CRXDE Lite (if you are using AEM 5.6, click Tools from the left menu). 
  3. Right-click the apps folder (or the parent folder), select Create, Create Folder.
  4. Enter the folder name into the Create Folder dialog box. Enter newUserApp
  5. Repeat steps 1-4 for each folder specified in the previous illustration. 
  6. Click the Save All button.

Note:

You have to click the Save All button when working in CRXDE Lite for the changes to be made.

Create a template 

You can create a template by using CRXDE Lite. A CQ template enables you to define a consistent style for the pages in your application. A template comprises of nodes that specify the page structure. For more information about templates, see Templates.

To create a template, perform these tasks:

1. To view the CQ welcome page, enter the URL http://[host name]:[port] into a web browser. For example, http://localhost:4502.
2. Select CRXDE Lite (if you are using AEM 5.6, click Tools from the left menu).
3. Right-click the template folder (within your application), select Create, Create
Template.
4. Enter the following information into the Create Template dialog box:

  • Label: The name of the template to create. Enter templateNewUser
  • Title: The title that is assigned to the template.
  • Description: The description that is assigned to the template.
  • Resource Type: The component's path that is assigned to the template and copied to implementing pages. Enter /apps/newUserApp/components/page/templateNewUser.
  • Ranking: The order (ascending) in which this template will appear in relation to other templates. Setting this value to 1 ensures that the template appears first in the list.

5. Add a path to Allowed Paths. Click on the plus sign and enter the following value: /content(/.*)?.
6. Click Next for Allowed Parents.
7. Select OK on Allowed Children.
 

Create a render component that uses the template

Components are re-usable modules that implement specific application logic to render the content of your web site. You can think of a component as a collection of scripts (for example, JSPs, Java servlets, and so on) that completely realize a specific function. In order to realize this functionality, it is your responsibility as a CQ developer to create scripts that perform specific functionality. For more information about components, see Components.

By default, a component has at least one default script, identical to the name of the component. To create a render component, perform these tasks:

1. To view the CQ welcome page, enter the URL http://[host name]:[port] into a web browser. For example, http://localhost:4502.
2. Select CRXDE Lite (if you are using AEM 5.6, click Tools from the left menu).
3. Right-click /apps/newUserApp/components/page, then select
Create, Create Component.
4. Enter the following information into the Create Component dialog box:

  • Label: The name of the component to create. Enter templateNewUser
  • Title: The title that is assigned to the component.
  • Description: The description that is assigned to the template.

5. Select Next for Advanced Component Settings and Allowed Parents.
6. Select OK on Allowed Children.
7. Open the templateUserApp.jsp located at: /apps/newUserApp/components/page/templateNewUser/templateNewUser.jsp.
8. Enter the following JSP code

<html>
<head>
<title>Hello World !!!</title>
</head>
<body>
<h1>Hello CQ Users!!!</h1>
<h2>This page will create  CQ users</h2>
</body>
</html>

Setup Maven in your development environment

You can use Maven to build an OSGi bundle that uses the JCR API and is deployed to Experience Manager. Maven manages required JAR files that a Java project needs in its class path. Instead of searching the Internet trying to find and download third-party JAR files to include in your project’s class path, Maven manages these dependencies for you.

You can download Maven 3 from the following URL:

http://maven.apache.org/download.html

After you download and extract Maven, create an environment variable named M3_HOME. Assign the Maven install location to this environment variable. For example:

C:\Programs\Apache\apache-maven-3.0.4

Set up a system environment variable to reference Maven. To test whether you properly setup Maven, enter the following Maven command into a command prompt:

%M3_HOME%\bin\mvn -version

This command provides Maven and Java install details and resembles the following message:

OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

 

Note:

For more information about setting up Maven and the Home variable, see: Maven in 5 Minutes.

Next, copy the Maven configuration file named settings.xml from [install location]\apache-maven-3.0.4\conf\ to your user profile. For example, C:\Users\scottm\.m2\.

You have to configure your settings.xml file to use Adobe’s public repository. For information, see Adobe Public Maven Repository at http://repo.adobe.com/.

The following XML code represents a settings.xml file that you can use.

<?xml version="1.0" encoding="UTF-8"?>

   | it to several places.
   |

   | repository, to be used as an alternate download site. The mirror site will be the preferred 
   | server for that repository.
   |-->
  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.

    </mirror>
     -->
  </mirrors>
  
  <!-- profiles
   | This is a list of profiles which can be activated in a variety of ways, and which can modify
   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
   | specific paths and repository locations which allow the build to work in the local environment.
   |
   | For example, if you have an integration testing plugin - like cactus - that needs to know where
   | your Tomcat instance is installed, you can provide a variable here such that the variable is 
   | dereferenced during the build process to configure the cactus plugin.
   |
   | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
   | section of this document (settings.xml) - will be discussed later. Another way essentially
   | relies on the detection of a system property, either matching a particular value for the property,
   | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a 
   | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
   | Finally, the list of active profiles can be specified directly from the command line.
   |
   | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
   |       repositories, plugin repositories, and free-form properties to be used as configuration
   |       variables for plugins in the POM.
   |
   |-->
  <profiles>
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated using one or more of the
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
     | or the command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.
     |
     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
    <profile>
      <id>jdk-1.4</id>

      <activation>
        <jdk>1.4</jdk>
      </activation>

      <repositories>
        <repository>
          <id>jdk14</id>
          <name>Repository for JDK 1.4 builds</name>
          <url>http://www.myhost.com/maven/jdk14</url>
          <layout>default</layout>
          <snapshotPolicy>always</snapshotPolicy>
        </repository>
      </repositories>
    </profile>
    -->

    <!--
     | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
     | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
     | might hypothetically look like:
     |
     | ...
     | <plugin>
     |   <groupId>org.myco.myplugins</groupId>
     |   <artifactId>myplugin</artifactId>

     |   </configuration>
     | </plugin>
     | ...
     |
     | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
     |       anything, you could just leave off the <value/> inside the activation-property.

Create an Experience Manager archetype project 

You can create an Experience Manager archetype project by using the Maven archetype plugin. In this example, assume that the working directory is C:\AdobeCQ.

plugin1

To create an Experience Manager archetype project, perform these steps:

1. Open the command prompt and go to your working directory (for example, C:\AdobeCQ).

2. Run the following Maven command:

mvn archetype:generate -DarchetypeRepository=https://repo.adobe.com/nexus/content/groups/public/ -DarchetypeGroupId=com.day.jcr.vault -DarchetypeArtifactId=multimodule-content-package-archetype -DarchetypeVersion=1.0.2 -DgroupId=com.adobe.cq.user -DartifactId=user -Dversion=1.0-SNAPSHOT -Dpackage=com.adobe.cq.user -DappsFolderName=myproject -DartifactName="My Project" -DcqVersion="5.6.1" -DpackageGroup="My Company"

3. When prompted for additional information, specify Y.

4. Once done, you will see a message like:
[INFO] Finished at: Wed Mar 27 13:38:58 EDT 2013
[INFO] Final Memory: 10M/184M

5. Change the command prompt to the generated project. For example: C:\AdobeCQ\user. Run the following Maven command:
mvn eclipse:eclipse

After you run this command, you can import the project into Eclipse as discussed in the next section.
 

Add Java files to the Maven project using Eclipse 

To make it easier to work with the Maven generated project, import it into the Eclipse development environment, as shown in the following illustration.

Users

The next step is to add a Java file to the com.adobe.cq.user package. The Java file represents a Java Servlet that uses the UserManager API. For information, see Interface UserManager.

The Java class uses these annotations:

@Service(value = Servlet.class)

@Component(immediate = true, metatype = true)

@Properties({ 

@Property(name = "sling.servlet.paths", value = "/services/SimpleUserGroup"), 

@Property(name = "service.description", value = "SimpleUserGroup"), 

@Property(name = "label", value = "SimpleUserGroup") })

The sling.servlet.paths property corresponds to the URL that you specify when using an AJAX request. 

The following code represents the SimpleUserGroup servlet that extends SlingAllMethodsServlet. This interface contains the doPost method that accepts a post operation (user and grop is posted to the servlet). The user and group values are then used to create an AEM user and group.

Build the OSGi bundle using Maven 

To build the OSGi component by using Maven, perform these steps:

 

  1. Open the command prompt and go to the C:\AdobeCQ\user folder.
  2. Run the following maven command: mvn clean install.
  3. The OSGi component can be found in the following folder: C:\AdobeCQ\user\bundle\target. The file name of the OSGi component is user-content-1.0-SNAPSHOT.zip.

Deploy the bundle to Experience Manager

Once you deploy the OSGi bundle, you are able to invoke the AEM servlet and create an AEM user and group. After you deploy the OSGi bundle, you will be able to see it in the Apache Felix Web Console.

OSGI

Deploy the OSGi bundle by performing these steps:

  1. Login to Apache Felix Web Console at http://server:port/system/console/bundles (default admin user = admin with password= admin).
  2. Click the Bundles tab, sort the bundle list by Id, and note the Id of the last bundle.
  3. Click the Install/Update button.
  4. Browse to the bundle JAR file you just built using Maven. (C:\AdobeCQ\user\bundle\target).
  5. Click Install.
  6. Click the Refresh Packages button.
  7. Check the bundle with the highest Id.
  8. Click Active. Your new bundle should now be listed with the status Active.
  9. If the status is not Active, check the CQ error.log for exceptions.

 

Add CSS and JQuery files to a CQ:ClientLibraryFolder node

You add a CSS file and a JQuery framework file to a cq:ClientLibraryFolder node to define the style of the client JSP. The JQuery framework file that is added is named jquery-1.6.3.min.js.

To add CSS files and the JQuery framework to your component, add a cq:ClientLibraryFolder node to your component. After you create the node, set properties that allow the JSP script to find the CSS files and the JQuery library files.

To add the JQuery framework, add a new node named clientlibs to your component (as discussed later). Add these two properties to this node.

Name Type Value
dependencies String[] cq.jquery
categories String[] jqueryrest

Site CSS file

The site.css file defines the display style for the client JSP file that lets the user enter and submit data. The following code represents the site.css file.

Clientlibs

You have to add two text files to the clientlibs folder. These text files map to the JS file and the CSS file. The names of the text files are: css.txt and js.txt.

The css.txt file contains the CSS file name: site.css. Likewise, the js.txt file contains the JS file name: jquery-1.6.3.min.js.

Add the files to the ClientLibs folder

  1. Right-click /apps/newUserApp/components then select New, Node.
  2. Make sure that the node type is cq:ClientLibraryFolder and name the node clientlibs.
  3. Right click on clientlibs and select Properties. Add the two properties specified in the previous table to the node.
  4. On your file system, navigate to the folder where the JQuery JS file is located. Drag and drop the jquery-1.6.3.min.js file to the clientlibs node by using CRXDE.
  5. On your file system, navigate where you placed the CSS file. Drag and drop the site.css files to the clientlibs folder by using CRXDE.
  6. Add a TXT file to the clientlibs folder named js.txt. The content of the js.txt file is the JQuery JS file name.
  7. Add a TXT file to the clientlibs node named css.txt. The content of the css.txt file is the CSS file name.

Modify the templateNewUser JSP file 

Modify the templateNewUser.jsp file to post data to the Sling Servlet that was created in this development article. In this example, a JQuery Ajax Post request is used and the form data is passed to the Sling Servlet's doPost method (the method defined in the SimpleUserGroup Java class). The following code represents the AJAX request.

 

<%@include file="/libs/foundation/global.jsp"%>
<cq:includeClientLib categories="jqueryrest" />
<html>
<head>
<meta charset="UTF-8">
<style>
#signup .indent label.error {
  margin-left: 0;
}
#signup label.error {
  font-size: 0.8em;
  color: #F00;
  font-weight: bold;
  display: block;
  margin-left: 215px;
}
#signup  input.error, #signup select.error  {
  background: #FFA9B8;
  border: 1px solid red;
}
</style>
<script>

  
$(document).ready(function() {
  
    $('body').hide().fadeIn(5000);
         
$('#submit').click(function() {
    var failure = function(err) {
             alert("Unable to retrive data "+err);
   };
  
    //Get the user-defined values that represent claim data to persist in the Adobe CQ JCR
    var myGroup= $('#GroupName').val() ; 
    var myUser= $('#UserName').val() ; 

  
  
    //Use JQuery AJAX request to post data to Sling Servlet that creates the group and user
    $.ajax({
         type: 'POST',    
         url:'/services/SimpleUserGroup',
         data:'groupName='+ myGroup+'&userName='+ myUser,
         success: function(msg){
             $('#Response').val(msg); 

         }
     });
  });
     
}); // end ready
</script>
</head>
    
<title>AEM User/Group Sample App</title>
    
<body>
      
           
    <h1>AEM User/Group Sample App</h1>

 </tr> 
  
 </table>
 
</form>

</html>

Modify the templateNewUser JSP file

  1. To view the CQ welcome page, enter the URL: http://[host name]:[port] into a web browser. For example, http://localhost:4502.
  2. Select CRXDE Lite. (If you are using AEM 5.6, click Tool in the left menu)
  3. Double-click apps/userapp/components/page/templateNewUser/templateNewUser.jsp.
  4. Replace the JSP code with the new code shown in this section.
  5. Click Save All.

 

Create an AEM web page based on the templateNewUser template 

The final task is to create a site that contains a page that is based on the templateNewUser template (the template created earlier in this development article). When you open this web page, you can post a user and group to the servlet. The user and group is created.  

Create an AEM web page based on the templateUserApp template by performing these tasks:

  1. Go to the CQ welcome page at http://[host name]:[port]; for example, http://localhost:4502.
  2. Select Websites. (If you are using AEM 5.6, click Tools from the menu on the left.)
  3. From the left hand pane, select Websites.
  4. Select New Page.
  5. Specify the title of the page in the Title field.
  6. Specify the name of the page in the Name field.
  7. Select templateNewUser from the template list that appears. This value represents the template that is created in this development article. If you do not see it, then repeat the steps in this development article. For example, if you made a typing mistake when entering in path information, the template will not show up in the New Page dialog box.
  8. Open the new page that you created by double-clicking it in the right pane. The new page opens in a web browser.
