[jboss-user] [JBoss Getting Started Documentation] - Getting AccessControlException from Applet trying to call EJ

[rmalhotr]

I am getting the following exception while trying to access EJB deployed on JBoss 4.0.3SP1 from an Applet:


  | java.lang.ExceptionInitializerError
  |         at org.jboss.proxy.SecurityInterceptor$3.run(SecurityInterceptor.java:87)
  | ......
  | ......
  | Caused by:java.security.AccessControlException:access denied (java.util.PropoertyPermission org.jboss.security.SecurityAssociation.ThreadLocal read)
  | .....
  | 


The exception is thrown from the line "inBox = inBoxHome.create();" in the following block of code: 
  
  |   /**
  |    *
  |    * @return a InBoxBean object
  |    * @throws java.lang.Exception
  |    */
  |   public InBox getInBoxBean() throws Exception
  |   {
  |     InBox inBox = null;
  |     try
  |     {
  |       Object ref = null;
  |       try
  |       {
  |         //look up jndi name
  |         ref = _context.lookup("InBoxBean");
  |       }
  |       catch (Exception ex)
  |       {
  |         System.out.println("_context.lookup('InBoxBean') failed with: "+ ex);
  |         //look up jndi name again
  |         ref = _context.lookup("InBoxBean");
  |         System.out.println("_context.lookup('InBoxBean') succeeded:");
  |       }
  |       //then cast to Home interface
  |       InBoxHome inBoxHome = (InBoxHome)PortableRemoteObject.narrow(ref, InBoxHome.class);
  |       // use Home interface to create remote interface
  |       inBox = inBoxHome.create();
  |     }
  |     catch (Exception e)
  |     {
  |       throw e;
  |     }
  |     return inBox;
  |   }
  | 

The only way I have been able make this work is by running the Java Plug-in on the client with security manager with the following policy:


  | grant {
  |    permission java.util.PropertyPermission "org.jboss.security.SecurityAssociation.ThreadLocal", "read";
  |    permission java.lang.RuntimePermission "org.jboss.security.SecurityAssociation.getPrincipalInfo";
  |    permission java.io.SerializablePermission "enableSubstitution";
  | };
  | 

Is there a way to make this work without have to do anything special on the client plug-in.

Thanks,
Rajeev
