      I deployed a seam2's application in JBoss AS 7. Exception "llegalArgumentException: Null path " occured.


      java.lang.IllegalArgumentException: Null path

      I made a module my.service. The module have a resource my_service.jar. In my_service.jar's root path, there is a seam.properties file.

      So  seam search seam.properties, my_service.jar is found. But,  url is like:


      In VFS.getChild method, url.toURI().getPath() is null. "llegalArgumentException: Null path " occured. Why is getPath() method's return null?

          In JarFileResourceLoader´╝âgetJarURI method , file's URI is created by "new URI("jar", b.toString(), null)".

          The value of b.toString() is liking "file:/D:/opt/jboss-as-7.1.0.Final/modules/kss/service/main/kss_services.jar!/seam.properties".

          But the getPath() of URI that is created is null. Is this a bug?

          Is there any approach to avoid the error?
