RE: Dependent-to-dependent relationships
Are these direct calls, between intra-container EJB's, specific to Orion? If so, how are conflicting settings for transactions etc., for the communicating beans resolved? Satish Gupta I entered this as bug #185 back in November. Nothing has been resolved yet. This isn't a huge issue since the workaround is simple: use ejb's for everything. this isn't as slow as it sounds since intra-container ejb method calls are direct and do not use rmi. __ Do You Yahoo!?

Explicit cast needed by Persistence Manager??
Hi,
In my application, A MemberProfileEJB has two non-EJB
dependent classes, WebProfile and Membership dependent

One of the business methods of MemberProfileEJB,
setMembership() looks as shown below. But when I try
to deploy this in Orion 1.3.8, I get the errors shown.
I am at a loss to see what the Persistence Manager
could be expecting.

Re: java.lang.OutOfMemoryError in Product Application
As per the suggestion, I am doing the following in an

still running and will croak tonight if this fix is
not effective.

Rationale for element?
What is the rationale for having element? I know the spec says that with this approach and ejb-ref is visible only within the scope of the referencing ejb. But that also means that each referenced ejb has to be included as a element of each referencing ejb. Doesn't this get away from the 'write-once' paradigm? Thanks for your input.
