Hi Town,
Your code works perfectly fine in my environment. (NT+IIS+Websphere 2.0). After some
meddling, I got
IOException-2, when the Servlet wasn't actually available (ie out of servlet
classpath). You pls check
(typing the servlet url in a browser) whether the servlet is accessible. Hope it
helps.
