CQ/CRX — How to download hotfixes/package from package share

To find out what hotfix/component/featurepack you need, please check hotfixes list for CRX or CQ.

To download and install the hotfix/component/featurepack:

1. Start your CQ/CRX service, and login to your CQ/CRX main page, click on package, then package share; you can also find package share by go to /crx, then click on package share.
You will be prompted for login. You need to use your Adobe ID to login. If you don’t have one yet, just click on register and create one. It only needs your email address as user name, and a password.

2. Once logged in, you can see a list of packages that is available. Note it will only display the first 5 Adobe package on the page, so you may not see the hotfix you needed. You can search the name/number of the package/hotfix you need from the top right searching box. For example, type in 36281 will find cq-5.4.0-hotfix-36281.
Note, you may find multiple versions of cq-5.4.0-hotfix-36281, use any one of them for download.

3. Before you download the package/hotfix, you should check the dependency first. Click on cq-5.4.0-hotfix-36281, it will display the detail about the hotfix. Pay attention to the Dependencies. For hotfix-36281, it has feature:cq-5.4.0-featurepack-35156:1.1 as dependencies. This means you should download feature:cq-5.4.0-featurepack-35156:1.1 first, then apply cq-5.4.0-hotfix-36281.
Note, if this feels complicated, you may want to open a support ticket to have support engineer guide you. Sometimes, there is a replacement hotfix that will allow you to use one later version of hotfix instead of download several packages. In our example, you can use cq-5.4.0-hotfix-34304 instead of using cq-5.4.0-hotfix-36281 and cq-5.4.0-featurepack-35156:1.1.

4. Once you know which hotfix is needed, click on download to download, and then click install to install the hotfix.

    Behind the scenes– what happens when you install CQ/CRX

    When you install CQ or CRX either by double click on crx-quickstart.jar/cq-quickstart.jar or using command line(doesn’t matter what run mode you are installing, a default mode, or author/publish mode), the following steps are performed during first installation:
    1. the quickstart is unpacked to the crx-quickstart directory, and you can see crx-explorer_crx.war & crx-launchpad.war under: crx-quickstart\server\webapps
    2. then cqse is started
    3. cqse starts the crx webapp
    4. the crx webapp starts the repository
    5. during repository start-up, it checks the repository/install folder for content packages and installs them (if repository/Tar/index is out of sync, will not start correctly)
    6. then the launchpad webapp is started
    7. Felix starts the core bundles
    8. one of the core bundles is the JCR installer, which searches all ‘install’ nodes in the repository and registers those bundles
    9. Felix starts the newly registered bundles

    There are three parts in CQ/CRX that will work together, they are descripted below:

    Where the data gets stored:

    • CRX uses the Tar Persistence Manager (TarPM), tar files are stored under:
    • CRX configuration files

    How to create class/jar files for data service project without using maven

    In the sample for “Create a Data Services application for the Experience Server that returns data“, it showed how to bundle your class for data service project into the template application and build/deploy the bundle using Maven. There are several ways to build the bundle without using Maven. I will add all the options here.

    For our sample, the class we need to build is this:

    package com.adobe.myexample;
    public class EchoService {
        public String sayHello(String val){        
            return "Adobe Digital Enterprise Platform says: " +val ;

    • Using CRXDE

    This is the easiest option for this task. It will compile your java class, build bundle and automatically install and start in the OSGI container. New user should use this option. For details, see “Creating a Bundle” section of the doc here. The following steps should be clear.

    Note, whenever work with CRXDE Lite, you have to click on “Save ALL” at the left top after you made any change (create/modify/delete) in CRXDE, and click on refresh to make sure the change has been saved/updated.

    1. Start your experience service and go to CRXDE Lite via http://localhost:4502/crxde

    2. Create a project by right click on apps, select create-create project, put in the following info:
    Project name: myapp
    Java package: com.adobe.myexample
    This will create folder /src, /install, and /components under myapp for you.

    3. Create a bundle by Right click the folder apps/myapp/src, select create-create bundle , put in the following info:
    Symbolic Bundle Name: com.adobe.myexample.TestEcho (this can be any name)
    Bundle Name: TestEcho Bundle (this is the name will be displayed in Felix console Bundle )
    Bundle Description: This is my Test Bundle
    Package: com.adobe.myexample (This must be your java package name)
    This will create com.adobe.myexample.TestEcho folder and com.adobe.myexample.TestEcho.bnd under it.

    4. create your java code by Right click on folder /apps/myapp/src/com.adobe.myexample.TestEcho/src/main/java/com/adobe/myexample, create–>create file, enter as name. Make sure it is at the same folder as Then click on , and then put your java code into the right side edit area. Save it.

    package com.adobe.myexample;
                       public class EchoService {
                       public String sayHello(String val){  
                           return "Adobe Digital Enterprise Platform says: " +val ;

    Note, If you already have your classes in a jar, then instead of creating class here, create a folder libs under /apps//src//libs/, then go to http://localhost:4502/crx and use “content loader” to import the jar into libs folder.

    5. build your bundle by Right click on com.adobe.myexample.TestEcho .bnd, select Tools–>build Bundle
    This will compile your java class, build bundle and automatically install and start in the OSGI container.

    To verify the bundle has been install into OSGI, you can check from Felix, http://localhost:8900/system/console/bundles/
    you can search by the Bundle name “ TestEcho Bundle” to find it. Click on the arrow to see the info about the Bundle. Make sure you have all the class in there and the proper packages are exported.

    • Convert a jar File into an OSGi Bundle
    When you have your classes in a jar, you can convert it into an OSGI Bundle, see details here

    1. Creating manifest file.
    This is the key to the process. In order for Bundle to be created correctly, there are several elements you need to pay attention to. You should have the following in the manifest file:
    Bundle-Name: (this will be the name displayed in the Felix console Bundle tag, you can search this name to check if the bundle is installed or active.)
    Bundle-Version: (should always use a higher number than the provirus version if a version has been installed, otherwise the new bundle will not be installed. But if you include SNAPSHOT like 1.0- SNAPSHOT, it will always install.
    Bundle-ClassPath: .,myapp.jar (make sure you have the correct name of the jar you want to convert.)
    Bundle-SymbolicName: (can be any name)
    Import-Package: (if you have dependency class/jar for your class, you need to import them)
    Export-Package: (this is the name of your java package name, must have this so that the class can be accessed by others)

    2. Create the bundle jar (myapp-bundle.jar) by using zip or java command:
    jar cvfm myapp-bundle.jar manifest.txt myapp.jar

    3. Install the bundle.
    Use content loader to load the jar under your app’s /install or /libs folder, like /apps/myapp/install/ and jar under /install or libs folder will be picked up.

    Note, the /install or /libs should not be at more than 3 layer under apps, for example, /apps/myapp/component/bundle/install, the bundle jar will not be picked up in this case.

    This can also be done by using curl command line described here.

    Another option is to install OSGi bundles via CRX packages as described in this techNote.

    How to Create a Data Services application for the Experience Server that returns data

    In Our development guide for Experience Service, there is an good example about “Create a Data Services application for the Experience Server that returns data”, see link here. It described all the details necessary for the project. However, there are a few places that could be confusing for users that are not familiar with CRX/CQ and Maven. In this blog I have re-organized and simplified the steps to make it easier to follow, and added Note in the places where it could be easy to make mistake or get confused. I have also put Troubleshooting Tips at the end. I hope this will make deploying to Experience Services easier for you.

    I have divided the task into three sections:

    • Prepare the development environment:
    • Create and configure server-side project
    • Create and configure client side project

    If this is the first time you work with data service 4.5 version(running on CQ servlet), please make sure you go through the first section to get your environment set up correctly for your future development.

    [Note] Step 6 to 8 is for using Maven to build and deploy the app. If you want to load you class/Jar and app directly into OSGI without using the template application and maven, you can skip these steps and follow the link here, then go to step 9.

  • Prepare the development environment:

  • 1. Download the Flash Builder 4.5 installer from here and install the software as described in Flash Builder 4.5 Release (Note, for MAC, you need to do more configuration. See here

    2. Install plug-ins for Flash Builder, see here.

    3. Setting up Maven in your development environment (If you don’t want to build the project via maven for developing test, you don’t have to configure this at this time)

      a. Download maven from
      b. After extract Maven to your machine, for example, c:/apache-maven-3.0.3, create an environment variable named M3_HOME, and point to c:/ apache-maven-3.0.3.

    4. Install and config ADEP Experience Services

      a. Download the Experience Services Quickstart JAR file from here . The file name should be something like adep-ria-quickstart-10-0-all-all.jar
      b. Make sure you have jdk1.6.0_26 or higher installed on your machine (but 1.7 is not supported). And set JAVA_HOME to point to the jdk1.6.0_26, and Path= %JAVA_HOME%\bin;
      c. Create a directory to run your ADEP Experience Services. For example, create c:/dataService_sample, and copy adep-ria-quickstart-10-0-all-all.jar into directory and rename it to adep-ria-quickstart-10-0-all-all-p4502.jar. (This will make the Experience Services to use port 4502).
      d. Start Experience Services by double click on adep-ria-quickstart-10-0-all-all-p4502.jar. This will take several minutes to install. Once it is done installing, a license page will come up, or you can access it by http://localhost:4502 . Log in using your Adobe ID and password to Retrieve License Key. (Note: the Adobe ID is the account you use to download any adobe software to access adobe lab or shared package. If you don’t have an account yet, you can go to to create one.)
      Once you get the license key and put in the license page, you will see ADEP Experience Services login page. Use admin/admin to login.
      e. From the welcome page, click on “packages”, scroll down and find Clicks on, then click download to save it on your machine. Then do the same to download

    Make sure you have all above installed and configured before you start to create or deploy your data service project.

  • Create your data service application server-side--using remote to return data
  • 5. Create your Java server-side class. For this example, we create a simple class named like this:

    package com.adobe.myexample;
    public class EchoService {
    public String sayHello(String val){
    return "Adobe Digital Enterprise Platform says: " +val ;

    Note: To compile your class, you need to have dataservices-bundle.jar in your classpath. (EchoService doesn’t need this because it is not using any of the data service classes). The dataservices-bundle.jar can be obtained from the you downloaded on step 4.e. It is under:[ZIP location]\dataservices-sdk-pkg\jcr_root\etc\aep\sdks\riaservices\dataservices\4.5.0\java

    6. To place the application files in the template application
    Extract you got from 4.e to a folder on your machine, say c:/template:

      a. copy dataservices-bundle.jar and put into the template application’s lib folder.
      b. Under the sourceCode\src\main\java folder, create a folder structure that reflects the Java package structure. For this example, it is: sourceCode\src\main\java\com\adobe\myexample.
      c. Place file in the myexample folder.
      d. Open pom.xml file under sourceCode folder, scroll down and find the following section:


    And change it to:


    Note: there are multiple mop.xml file in the template app, make sure you modify the one under sourceCode folder, otherwise your app will not be built correctly.

    7. Using Maven to build the package:
    Open command prompt under c:/ template, enter the following command:
    %M3_HOME%\bin\mvn clean install

    Make sure the build was successful by looking at the log. After the build was successful, it will create a zip file dataservices-example-app-bundle-1.0-SNAPSHOT.jar under c:/ template/package/target

    8. Deploy your app to Experience Services:

      a. Go back to http://locahost:4502, click on Packages, then click “Upload package” from the menu, then select dataservices-example-app-bundle-1.0-SNAPSHOT.jar under c:/ template/package/target.
      Click on dataservices-example-app-bundle-1.0-SNAPSHOT.jar that’s displayed there, then click Install.

    Note, make sure you click install, otherwise the jar is not loaded into the experience services.

      b. To confirm your package was deployed, to go OSGI console by http://localhost:4502/system/console/bundles (or you can go to welcome page, click on OSGI console, then select bundle tag), login using admin/admin
      Then search your bundle to make sure it is here, and click on the arrow beside the [package name to see the details and make sure your class is in there.
      c. To confirm your RDS is enabled: go to http://localhost:4502/system/console/configMgr
      click on “Adobe data Services”, then check enable RDS

    9. Defining the server destination for the echo service

      a. Go to http://localhost:4502/crxde , from left panel, find: /etc/aep/config/dataservices/destinations/remoting Right click on remoting folder, and select create-create file, put the file name as com.adobe.myexample.xml, click OK.
      b. Double click the com.adobe.myexample.xml file, then add the following in the to file (at right)

    <?xml version="1.0" encoding="UTF-8"?>
      <destination channels="my-amf" id="echo">

    From the top menu, click the Save All button. (Don’t forget about this step).

  • Creating a Flash Builder client project for the Echo service
  • Start flash builder 4.5 (make sure the Modeler plug-in is installed by step #2)

    10. Before you create a flash builder project for your app, verify you can see the destination you created in step #9 :

      a. Change perspective to Data Model from flash builder by clicking Window, Open Perspective, Data Model,
      b. Search echo in the Remoting destinations folder.

    11. the a Flex Project for ADEP Experience Services application

      a. create a project “Flex Project for ADEP Experience Services”
      b. From the RDS server, select Experience Server (localhost)
      The host name for RDS is localhost, port is 4502, user account admin/admin.
      c. Click Test Connection button to verify connection. If it can’t connect, check and make sure the service is started (see step#4.d), and RDS is enabled (see step #8.c)
      d. Put the client code from the doc sample
      e. Run the client code from flash builder

    Troubleshooting Tips:

      1. Get Fault: “cannot create class of type ‘com.adobe.myexample.EchoService’”

    This indicates your class is not loaded into the OSGI. Double check Step 5, 6, 7, 8, and reinstall your package.

      2. Get “connection failed” error

    This ould be caused your RDS not enabled or configured correctly, see step 11.c. It also could be channel/destination configure issue, you may want to double check your channel/destination configure to make sure all the sytax and spell are correct.

      3. Get error indicating my-streaming-amf:

    go to
    http://localhost:4502/crxde , open /etc/aep/config/dataservices/services-config.xml from the left panel, you can see the section:

               <channel ref="my-streaming-amf"/>        
               <channel ref="my-polling-amf"/>      
               <channel ref="my-amf"/>

    <channel ref="my-amf"/>

    to be the first item in there, and restart the server and re-run the client code, this should get rid of the error.
