amazon simpledb + simplejpa + jpacontainer

I would really like to use amazon’s simpledb rather than the rds. I found an implementation of jpa 1.0 for simpledb (simplejpa) and I thought that if I got this working, which it is, I could just hook up jpacontainer. After all, simplejpa is standard jpa implementation.

However, I am not able to get past a “java.lang.ClassNotFoundException:” for my data class. Is there something I need to do, or am I completely off base in thinking I could use jpacontainer with simplejpa?

See below for how simplejpa is used.

Thanks

I added the following Apache libs to a netbeans project to get Vaadin to work with Amazon SimpleDb

commons-loggin-1.1.1.jar
httpclient-4.1.1.jar
httpcore-4.1.jar
httpclient-cache-4.1.1.jar
commons-codec-1.4.jar
httpmime-4.1.1.jar

After adding the libs the program works both locally and on Amazon beansalk.

Let me know if this works in your setup.

SimpleJPA is a very incomplete JPA implementation - from
http://code.google.com/p/simplejpa/
:

JPAContainer was never been tested with SimpleJPA and it is likely that SimpleJPA lacks some of the features required by JPAContainer.
