How did you create this code? Please explain your steps on how to created the OSGi bundle.

YOu should be using an Adobe Maven Archetype project and use the UBER JAR that corresponds to the version of AEM.

For example - see this artilce to learn how to use Maven Archetype 11 and UBER JAR for 6.3 -- Scott's Digital Community: Creating an Adobe Experience Manager 6.3 Project using Adobe Maven Archet...

[smacdonald2008]

See this AEM Artilce for 6.4. Its a similiar use case - we are querying the JCR and placing the data into XML to display it within a JQuery plug-in. It will help you -- Scott's Digital Community: Querying Adobe Experience Manager 6.4 JCR data

[smacdonald2008 · Accepted solution]

I took your code and placed it into a Maven 10 Arch project as you are using felix SCR annotations. (Maven 10 still uses these annotations -- org.apache.felix.scr.annotations.Component).

Adobe Experience Manager Help | Creating your first Adobe Experience Manager 6.2 Project using Adobe...

I made a few code changes - like removed the @nonnull - AEM does not like that.

I updated the POM dependencies to run on 6.3 - as shown in this video

Here is my result....

[shaik671144]

Could you please suggest me in which i can proceed.

my requirement is to convert AEM data in to xml

[smacdonald2008]

To convert AEM JCR data - you need to QUery the JCR data, then use Java XML classes to convert the data to XML - this is all explained in this article -- Scott's Digital Community: Querying Adobe Experience Manager 6.4 JCR data
