Shorten the temp directory used by WebSphere® Portal Server (WPS), following the steps described below:

Start the WebSphere Portal Server V6.0, and using the WAS Administrative Console, navigate to the servers

Application Servers > Portal server(注意此处是portal server，
而不是app server,否则无效) > Java™ and Process Management 
> Process Definition > Java Virtual Machine page.

In the Generic JVM arguments, fill in: -Dworkspace.user.root=C:\tmp Save and re-start the WebSphere Portal Server。When the server restarts, it will then use the C:\tmp directory as the WebSphere Portal Server temp directory.

This fixes the problem. 好像IBM有Pack针对这个问题，以上的可以作为一个workaround. 在以下WAS/WPS测试通过。 IBM WebSphere Application Server - ND, 6.0.2.9 Build Number: cf90614.22 Build Date: 4/7/06
