the ".do" URL sounds like Struts? If yes: ask your question in the struts forum.
In short: your long URL is a GET request. You could convert this to POST requests, if you place all parameters as hidden fields in a form.
But this is a matter of your app, no JBoss issue.
Thank you for the input. I was googling around when i stumbled upon something they called mod_rewrite. But it was for apache. I was wondering if there are similar thing that we can use for jboss.
