Problem get ACL using WVCM API when using Tomcat5

[Frank Li]

I am using the latest Slide 2.1 b2 and  the 
proposed Wvcm client API to access Slide server. 

Here is my program:

ControllableResource resource = getControllableResource(resPath);
List acl = resource.doReadAccessControlList(true);

Here is the exception I got:

javax.wvcm.WvcmException: Moved Temporarily

The problem happens only when I run Slide on tomcat 5. 
It does not happen when I run Slide on Tomcat 4.1.30. 
The same for Slide 2.1B1 and Slide 2.1M1.

Thanks
