I don't know if you and Fred are looking at the same problem.
Your home and the jaws.xml should both be findByIdAndName, you shouldn't
have an ejbFindByIdAndName, since you're declaring it in the descriptor.
Fred's issue is that JBoss currently _requires_ the 'By'. I believe this
is only true of autogenerated single column finders. Fred, can you
confirm that what I just said summarizes your problem. No to fix that so
that find... or findBy... are supported, how does JAWS tell cases where
the field name starts with 'by' from a 'findBy...' Hmm that's a problem
anyway isn't it. I guess in those cases, you'd have to define the finder
in jaws.xml
Nathan, looking at the JAWS code, the only thing I could think of that
would cause your problem would be that JAWS gets a bad copy of jaws.xml,
without your finder declaration in it. Is it possible that it's getting
another copy out of your classpath, or somewhere. The only other thing
is a non-obvious, non-visible difference between the finder method's
name in the home interface and the name in jaws.xml. Do you have any
whitespace in the method name in jaws.xml (including line breaks)?
