Servlet using RMI

[Lam Sze Kin]

Dear all,

   

    I am using Apache 1.3.4 + Jserv 1.0b2 + SSL on Solaris 2.5.1.  These days, I am trying to write a simple servlets to talk to my first RMI server.  However, the servlet keep throughing the following exception:

   

       java.security.AccessControlException: access denied (java.net.SocketPermission 1
27.0.0.1:2233 connect,resolve)
        at java.lang.Throwable.fillInStackTrace(Native Method)
        at java.lang.Throwable.fillInStackTrace(Compiled Code)

        at javax.servlet.http.HttpServlet.service(Compiled Code)
        at org.apache.jserv.JServConnection.run(Compiled Code)
        at java.lang.Thread.run(Compiled Code)

 

    The servlet throws the exception at the code registry.lookup:

 

    try {

            Registry registry = LocateRegistry.getRegistry("localhost", 2233);
            ms = (MessageServer) registry.lookup("KinMessageServer");

    } catch (Exception e) {

            e.printStackTrace();

    }

 

    I have already add the directory of the servlet to java.policy and grant all permission to it.  Also, I have copied the server stub/skel classes to the directoy of the servlet.  Is there anyone know how to fix this problem?

 

    Thank you very much for your help.

 

yours,
