Subject Re: iBatis within EAR files
Date Fri, 07 Apr 2006 17:44:30 GMT
The client?  The client is in my.jar which is a bunch of EJBs plus a class
wrapping a DAO.  The war file is in a separate deployment.  It looks up an
EJB interface, calls it.  The interfaces are shared in a common library
outside both WAR and EAR (global scope).

That eventually gets me inside my.jar.  my.jar DAO wrapper classes calles

The ibatis libraries are part of the my.jar MANIFEST within the EAR.  The
ibatis libraries are in the EAR under a lib directory (MANIFEST has
Class-Path entres lib/ibatis.jar ,etc.)..

The only way for me to get this to work is to use Thread.currentThread
().setContextClassLoader(myDAO.class.getClassLoader()) before calling the
getResourceAsReader() but then for a common typeHandler callback defined in
an external library (with global scope) is not found.  I'm not even sure if
I really should have to do this.

Thanks for the feedback,
