Hi, I have a problem with the archive naming inside an EAR. Here is the EAR structure: | a.ear | +- META-INF | | +- application.xml | | +- jboss-app.xml | +- b.jar | +- c.war | A class in c.war is calling a class in b.jar. All is working fine, but if i rename b.jar to b-b.jar (with an hyphen) and update application.xml accordingly, i get a NoClassDefFoundError. I also tried with b_b.jar and that works. So it seems that file names in an EAR cannot have a "-" with JBoss ??? Could someone answer that annoying question ?
