Storage Extension working on Tridion 2011 version is not working on Tridion 2013

Question

I have written a Storage Extension for dynamic component presentations (based on JPAComponentPresentationDAO) as stated HERE in a SDL Tridion 2011 setup. It was working fine.

However, if I try to run this storage extension on SDL Tridion 2013 SP1 setup even if it is compiled with all the latest JAR files; it gives the below error in the log:

java.lang.RuntimeException: Fatal error, unable to load the StorageManagerFactory

Answer 1

I realized that the JPAComponentPresentationDAO which is the base class we are using in our custom storage extension class have got changed a lot in terms of the class members and the method signature. This required us to re-write and re-build the class inherited from this DAO such that it implements and reflect correctly all the parent members.

A step-by-step guide for storage extension has been updated and written at my blog HERE

I hope it will help others while implementing Storage Extension for SDL Tridion 2013. UPDATE: As requested, adding the class as under:
