Remove jsessionid from URL

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>

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

• 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));
