Not sure if this is the right forum for this question, but I have a Seam project that needs to include the "client" folder jars from a JBoss EJB3 server to access EJBs on that server. I can't use the JBoss 4.2.1 client jars, because then I get a serial number mismatch. If I include those jars, will they mess anything up in Seam? tia, Mike PS: I can't upgrade the remote server because its a third party application.
