[jboss-user] [JBoss Seam] - Re: [NamespaceScanner] Cannot load package

[alexeinov]

I found out that the described effect occurs when JBoss is started with Sun's jdk1.5.0_12 JVM. Running it with JRockit 1.5 or with Sun's jdk1.6.0_2 does not lead to this problem.

Debugging of NameScanner have shown that the method getPackage() cannot obtain a package info.

  |     protected Package getPackage(String name) 
  |     {
  |         try 
  |         {
  |             Class c = classLoader.loadClass(name + ".package-info");
  |             return c != null ? c.getPackage() : null;
  |         } 
  |         catch (Exception e) 
  |         {
  |             return null;
  |         }
  |     }
  | 

The loadClass() method throw exceptions like this:
anonymous wrote : java.lang.ClassNotFoundException: org.jboss.seam.drools.package-info

As a result of this error no namespace-prefixed components are initialized in component.xml, after that lots of things go wrong. For instance, core:init component will be uninitialized, which makes that jndiPattern is not set, which in turn makes that no application components can be accessed in an EJB module.
