OK,
I have an applet which calls a class which tries to get the connection to
the EJB.
The WebLogic server is running on port 7001 as usual. The codebase param in
the HTML file is set to "myclasses/" and I have a ClassFileServer (provided
by Sun, which only serves .class files) running on port 2001 and the
CLASSPATH in the ClasFileServer is set to c:\public_html\myclasses.
And when I call getCodeBase().getHost() it returns the name of my computer,
which I save in the variable 'host'.
Then I use the code below to set the InitialContext, but in the line
InitialContext ic = new InitialContext(p);
I get a NullPointerException with the following stack trace:
java.lang.NullPointerException
at weblogic.common.internal.ServerURL.findOrCreateRJVM(SeverURL.java:144)

weblogic.jndi.WLInitialContextFactory.getInitialContext(WLInitialContextFact

Thanks a lot for any help,
Noelia
