That's the idea. And, as a bonus, it works the same on Linux, Solaris, OS/X, . OK. I've realised that TC should handle security and now it works - on 5.0.19, imbeded in JBuilder. Well, I meant ot say it partially works. This is what I have set: -Djava.security.manager -Djava.security.policy=.../conf/catalina.policy -Djava.rmi.server.codebase=http://localhost:8080/MyApp/classes/ All seams to work except, I get a class cast exception when I cast this: Object obj = Naming.lookup( //localhost/Search ); SearchRMI search = (SearchRMI) obj; The funny thing is, when I inspect the result from the JBuilder, it shows that obj is of a class SearchImpl_Stub, which implements SearchRMI interface. I suspect I'm being hit with some RMI classloader issue, so my next question is: Has anyone done this? And what am I doing wrong?

Tomcat and RMI client - setup
Hi all.
This might be a simple question. I have a working RMI client and server.
I have tested it no problem. Now I would like to make a JSP/Servlet that
will act as a RMI client and connect to the RMI server running outside
Tomcat JVM.
I keep running into access permission violations. I understand that I
need to setup security policy, I had that for RMI. One thing than makes
me slightly suspicious, is the fact that when I debug TC/RMI combo, I
can see that my RMI client enters into setting up RMISecurityManager:
if (System.getSecurityManager() == null) {
goes in = System.setSecurityManager( new RMISecurityManager() );
}
Is that OK? I thought TC would setup security manager.
Now, my question is, what about Tomcat? If I want to run this, what do I
need to do?
If I get it, I need to:
- setup catalina.policy
- run it with -security option
I'm on Windows XP, how do I enable security mode for TC?
Am I barking up the wrong tree?
Nix.

Setting an SM this late could cause wierd problems, depending on what
permissions it doesn't grant, so it's probably at the least a bad idea. TC
only sets up the SM if you start it with '-security'.
