I assume you also have a servlet mapping, right? It would need to look
like this:
<servlet-mapping>
<servlet-name>myServlet</servlet-name>
<url-pattern>/myservlet</url-pattern>
</servlet-mapping>

Tomcat has no way to know whether the request came from the location line
of the browser or via JavaScript -- so that's not the cause of the
problem. You can look at the access log (in the "logs" directory) to see
what URI is really being requested when you do it manually, and when the
Javascript function calls it, to ensure that they are really identical.
One other thing to check is that your servlet mapping is really for
"/myservlet" and not for "/myServlet". URLs are case sensitive, so this
would cause a mismatch.
