How to configure ExtJS 6 on Aptana/Eclipose

How to configure ExtJS 6 on Aptana/Eclipose

This is off-track, not related to CQ development. However, when you're a CQ developer you would want to explore the technologies related to it. That's what I've attempted to do.

There are many blogs and posts available on Internet that talk about how to configure ExtJS versions < 5. However, they're confusing and misleading if you're trying to configure ExtJS 6. Here are few small changes those should be done in order to save the efforts.


First of all ExtJS 6 doesn't come with jsb2 files. I was really confused about how to configure ExtJS when I dont see the jsb2 file. So now, instead of jsb2 file, you need to add new folder and select /ext-6.0.0/build folder like this

The same can be verified by typing Ext. and pressing ctrl+space to see if your ExtJS has been configured properly or not on a js file.

Further this site has detailed tutorial on ExtJS.

Workflow Authorization error

Workflow Authorization error

While working with Workflow in AEM 6 and above or CQ5.6, it is important to ensure all the user access is provided correctly in either case following error can be encountered. In my case, the user group itself was not present. Again, this was because I had copied workflow from other location and not created it on my instance from the scratch.

Workflow version error

Workflow version error

I faced an exception like this while I was working on workflows for the first time

com.adobe.granite.workflow.core.jcr.WorkItemAdapterFactory error adapting a class of type [{org.apache.jackrabbit.core.NodeImpl}] to type [{java.lang.Class}] com.adobe.granite.workflow.model.VersionException: Version 1.84 does not exist for /etc/workflow/models/XYZ/XYZ-components-workflow/jcr:content/model

at com.adobe.granite.workflow.core.WorkflowSessionImpl.getModel(WorkflowSessionImpl.java:279)
at com.adobe.granite.workflow.core.util.NodeReader.createWorkflow(NodeReader.java:211)

The reason behind this exception is the version difference of workflow instance which I bump into because I was copying workflow from different locations and somehow the sync between the current workflow version and instance workflow version were messed up. Different workflow instances (as per their modification dates) can be seen at following location.

/etc/workflow/instances

AEM 6.0 with Multiple jdk

AEM 6.0 with Multiple jdk

Here I will be specifying the challenges I faced while trying to configure AEM 6.0 with multiple jdk on my local environment.

The first challenge I faced while working with AEM 6.0 was to make it run within my machine which is configured for java 1.8.

AEM 6.0 sp 1 does not work with jdk 1.8

For any AEM version starting from CQ5.6 it is required to install service pack 3. You can find the same on adobe site.

You can find more technical requirements at Adobe site

So I was left with one of the two options :

1. Setting my machine to run of JDK 1.7  
• Configuring the JAVA_HOME and Path environment variables to point to your JDK 1.7
• Checking the same using java -version on command prompt
• Also check which exe is there in system32 folder
2. Running AEM 6.0 with JDK 1.7 (some how)
• For this one you can use a java command that is twisted like

C:/Program Files/Java/jdk1.7.0_25/bin/java.exe -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=30303 -XX:MaxPermSize=1024M -Xmx1024m -jar aem-author-p4502.jar -nofork -gui
