how cognos (ear) display images in Websphere

[Eag. E]

Hi Gurus

I have deployed cognos (disp) into Websphere, it works fine, only problem is that I can not see images (statics files), nor js.

Currently I generated disp.ear through Configuration, then deploy this to Webshere. But I can not see images through url like url:9080/p2pd/servlet/dispatch.
Similar issue has been occurred in Tomcat, but we always copy static file from webcontent/* to webapp/p2pd, then it will work through url like url:9300/p2pd/servlet/dispatch.

So my question is how to import these static files to WAS


Thanks
