Accessing T3FileSystem from EJB

[Brett Schmoll]

Hi-

I'm encountering an error trying to write a file from an EJB. When I run the
same code from a stand-alone client it works fine. We're using WL6.0 sp2,
here's a copy of the code and stacktrace. Any ideas on why this doesn't
work?
...
Context ctx = null;
//
// Look-up T3Services context on the WebLogic Server...
//
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, PosseAppProperties.getEjbURL());
env.put(Context.INITIAL_CONTEXT_FACTORY,
weblogic.jndi.WLInitialContextFactory.class.getName());
env.put(Context.SECURITY_PRINCIPAL, "system");
env.put(Context.SECURITY_CREDENTIALS, "password");

ctx = new InitialContext(env);
// T3ServicesDef t3s =
(T3ServicesDef)ctx.lookup("weblogic.common.T3Services");
T3ServicesDef t3s = T3Services.getT3Services();
//
// Get the file system and the file
//
T3FileSystem fileSystem = t3s.io().getFileSystem("simulate");
T3File serFile = fileSystem.getFile(getBeanName() + ".ser");
T3File xmlFile = fileSystem.getFile(getBeanName() + ".xml");
...
I've tried both ways to retrieve the T3ServicesDef, the un-commented one was
suggested in another post. Both seem to work but the EJB fails on the
getFileSystem("simulate").
