I have created a simple entity bean, exactly as it appears in my Eclipse 3.0 book.

Is there an XDoclet configuration issue that I am missing. This simple bean should deploy properly.

Any help is much appreciated.

[Riyad Kalla]

From the XDoclet site, it looks like you might be missing an @ejb.persistence tag on your PK method:
http://xdoclet.sourceforge.net/xdoclet/tags/ejb-tags.html#@ejb_persistence__0__1_

[drowell]

That was the problem. Thanks for the help and for the XDoclet link

[Riyad Kalla]

no problem, glad it helped.
