|One further example. Let's say you have two components with two
|different classloaders wanting two different namespaces:
|Thread.setContextClassLoader(loader1);
|Context ctx = (Context)new InitialContext().lookup("java:comp");
|ctx.createSubcontext("env");
|ctx.bind("foo","bar"); // Bind java:comp/env/foo to bar in component 1's
|namespace
|
|Thread.setContextClassLoader(loader2);
|Context ctx = (Context)new InitialContext().lookup("java:comp");
|ctx.createSubcontext("env"); // No env currently in loader2's namespace,
|so create it
|ctx.bind("foo","xyzzy"); // Bind java:comp/env/foo to xyzzy in component
|2's namespace
|
|Thread.setContextClassLoader(loader1);
|new InitialContext().lookup("java:comp/env/foo"); // Result is "bar"
|Thread.setContextClassLoader(loader2);
|new InitialContext().lookup("java:comp/env/foo"); // Result is "xyzzy"
|
|Do you see? Pretty easy to use IMO...
yeah that helps... <teen-voice>like, *alot*</teen-voice>
ok so java:/comp is thread local, better than java: being thread local like
we used to
this is why java: is vm local, it's going in the right direction, but java:
is global
