Client exceptions with JBOSS 3.2.1

[drjohnfoster]

I am trying to run a client app. which calls an EJB deployed under JBOSS 3.2.1 and J2SE 1.4.1.
It finds the initial context OK, but fails on the JNDI lookup of the Register EJB with the following exception:

Exception: null

I read somewhere that I needed to add the following code:

System.setSecurityManager(new java.rmi.RMISecurityManager());

With this line addes, I get the following exception:


Exception: access denied (java.net.SocketPermission 230.0.0.4 connect,accept,re
olve)

Can anyone help me resolve these?

Check your security policies. See this for more information.
http://developer.java.sun.com/developer/onlineTraining/Programming/JDCBook/appA.html

If it is an applet-based application, consider signing it. See this:
http://java.sun.com/docs/books/tutorial/security1.2/toolsign/index.html

RTFEM!

The error message states quite clearly that this is a ClassNotFoundException - the security manager problem is a consequence, not a cause. Fix the ClassNotFoundException and you fix the problem.
Mea culpa.

So which problem are we solving? First or last?

[jonlee]

Had thought we had moved past the security manager issue. The security policy is related and you must specify a policy for the security manager. That is the consequence of defining the security manager.

e.g. -Djava.security.policy=mage.policy -Djava.security.manager

Hi jonlee,


I have traced your help across different forums to solve my problem.The last link is the one of integration between Lotus Domino Web-Server and JBoss 3.2.1 Application server.

I have a jndi lookup from the servlet placed in the Lotus Domino server to the Bean deployed in the jboss server.The same servlet when placed in the Tomcat webserver runs fine.But in the Lotus Domino server it throws the following error :

There was a reference on http://www.advisor.com/doc/09164
which says

add these lines:

permission java.util.PropertyPermission
"java.naming.factory.initial", "write";
permission java.util.PropertyPermission "java.naming.provider.url", "write";
permission java.net.SocketPermission "xx.xx.xx.xx:8083", "connect,resolve";

(xx.xx.xx.xx is the IP address of your EJB container.)


Though I have made the changes still the problem continues.Please help me out
