No longer able to build ejb using appc (WLS 8.1)

Question

I'm in the process of re-writing some build files to make use of the new
appc compiler, but I started to get a rather confusing error. Although
the EJB builds (using ejbc) and deploys fine on WLS 7, when I try to
build using appc I get a slew of messages such as "In EJB MyEJB, the
bean class must implement directly or indirectly the
javax.ejb.SessionBean interface" (which it does), or "In EJB MyEJB,
method remove() defined in the local interface either does not exist in
the bean class, or it is not a public method in the bean class". A
portion of the error message is listed below. I'm sure it must be some
kind of problem with my configuration...has anyone seen this before?
Any suggestions?
Thanks in advance,
Tim

Hello Tim,
Which version of WLS 8.1 are you using (beta or GA) ?
Also, make sure that you don't have any jar files from WLS 7 still on your classpath,
so that appc doesn't get confused. Also, how are you invoking appc?
Best regards,
Ryan LeCompte
