I made two programs (test1.ear, test2.ear) of the same content of processing. As for two program, the package name and the class name are different respectively. The name specified with @NAME is the same. The error doesn't go out when I deployed it those ear files. However, even if it accesses which program, the class in the previous deployed is called. The name specified with @Name was being written keeping to unique in the tutorial. Should I do uniquely in all packages that not only are made the name unique in the same package but also are used with Seam?
