Session problem when testing a simple web application in Websphere 6.0

[FrankSong]

Hi, all:

We met a problem when deploying a web application under ws6. The application is a struts example posted at :

http://www-128.ibm.com/developerworks/websphere/techjournal/0302_fung/fung.html

We used WSAD5.1 to generate this application(it works fine when testing it under the ws51 test environment) and deployed the war file in ws6 application server. We overrode the "Session tracking mechanism" property in ""Session Management" and set it to only use "Enable URL rewriting". However, when we click the submit button, the URL appears like:

http://localhost:9080/Test/submit.do;jsessionid=00006LOd8PJqaHFPs86szbzBVqh:-1

and it shows the error:

Error 404: Invalid path ;jsessionid=00006LOd8PJqaHFPs86szbzBVqh:-1 was requested

Does anyone know what is the problem?? Thanks!
