Re: [eclipselink-users] Slow load time

I did start it up in debug mode and was able to get a stack trace of what was
going on at that time looks like this -

The odd thing about that is it is the process is looking for this file -
\LineCPP\WebContent\WEB-INF\classes\com\gmrc\jpa\domain\CpUserroleId.class

But LineCPP is my WebProject 
and the CpUserroleId.class is in my JPA project
\CpsJPA\bin\com\gmrc\jpa\domain\CpUserroleId.class

It does this for all files in the persistence.xml even some eclipselink
files
\LineCPP\WebContent\WEB-INF\classes\org\eclipse\persistence\internal\expressions\QueryKeyExpression.class

I have 9 different WebProjects and I think it searches through all of them.

Any ideas on whats going on here?
