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...
