Hi,
We are facing a hard-to-debug problem i our Weblogic server.
The problem has something to do with errors in the classloading
process.

- Here is the exception:
<exception>
...Root cause of ServletException:    java.lang.NoClassDefFoundError
A.init ( a.java 3 )
</exception>

- Here is the setup ( pseudo code, may not compile ):
<code>
public class A{
   init(){
       B b = new B( );
   }
}

public class B{

   // static attributes
   public static HashMap map;

   private static final String VAL_1 = "value1";
   private static final String VAL_2 = "value2";
   private static final String VAL_3 = "value3";
   private static final String VAL_4 = "value4";
   private static final String VAL_CS = "value4";
   private static final String VAL_BS = "value4";

   private static final List prod_cs =
ProductHelper.getInstance().getAllProducts( new Category(CS) );
   private static final List prod_bs =
ProductHelper.getInstance().getAllProducts( new Category(BS) );
   ...

   // static methods...

   // static block
   static{
       map = new HashMap( );

       map.put(  "val1", VAL_1  );
       map.put(  "val2", VAL_2  );
       map.put(  "val3", VAL_3  );
       map.put(  "val4", VAL_4  );
       map.put(  VAL_BS, prod_bs  );
       map.put(  VAL_CS, prod_cs  );
      ...

   }
   }
}
</code>

As seen in the exception, probable cause is that B is not initialized.
Can someone explain
exactly what happens in the scenario where something in
ProductHelper.getInstance().getAllProducts()
fails...?

PS. The names have been changed to protect the bla bla...
