java.lang.NoClassDefFoundError: javax/persistence/Transient (google already... )

[Daniel]

Hi

I got a simple small project using objectify 3.1 (b.t.w if there possibility to get 4.0 from somewhere I don't mind at all)

anyway I'm getting an exception when trying to create a new DAO Object

Seen similar stack trace over here: https://groups.google.com/forum/?fromgroups#!topic/objectify-appengine/gsp3XlecC00 , but I already got those jar in my project , so what can be the reason for that exception

b.t.w I;m using GAE SDK 1.6.4

Here the complete stack trace:

Just add javax.persistence.jar from sun's distro.

Thanks that solved it!

Any Idea why I didn't need that jar in my other project with Objectify 3.0 ?

The JPA annotations are included with the GAE SDK if you check the "use JPA/JDO" checkbox.  This checkbox is a recent addition; in the past, all GAE projects automatically included the JPA classes, so the annotations were always present.

It was a mistake to use the JPA annotations.  Ofy4 does not use them.

Right now the best place to get Ofy4 is by building from trun...errr...master.
