• PrettyFaces
• Tomcat server

Answer 1

For tomcat 7 add this to web.xml

<session-config>
  <!-- Disables URL-based sessions (no more 'jsessionid' in the URL using Tomcat) -->
  <tracking-mode>COOKIE</tracking-mode>
</session-config>

Answer 2

The following filter may solve your problem (from http://randomcoder.org/maven/site/randomcoder-website/cobertura/org.randomcoder.security.DisableUrlSessionFilter.html)

package com.companyname.projectname.web.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletResponseWrapper;
import javax.servlet.http.HttpSession;

Answer 3

• Tomcat 6, add disableURLRewriting="true" in your context.xml

• Tomcat 7 and ServletFilter have already been discussed

• Or programmatically :

servletContext.setSessionTrackingModes(EnumSet.of(SessionTrackingMode.COOKIE));

Answer 4

You can add that settings into your http tag as follows:

<http auto-config="false" disable-url-rewriting="true">

Answer 5

Jetty WebappContext:

Set<SessionTrackingMode> trackingModes = new HashSet<>();
trackingModes.add(SessionTrackingMode.COOKIE);
context.getSessionHandler().getSessionManager().setSessionTrackingModes(trackingModes);

Answer 6

If you are not using Servlet 3.0, you can also achieve this using a PrettyFaces Rewrite Rule: http://ocpsoft.org/support/topic/url-rewrite-removing-the-jsessionid-from-the-url#post-410
