An ear file is extracted and the files are placed uncompressed on the file system. But that's more temporary storage than a cache.
Are you having a ClassNotFoundException or something of the sort? Changes not being incorporated after deployment?

Hi Cameron McKenzie,
Thanks for your reply.
Our Websphere app server has recently been upgraded to version 220.127.116.11 on both Dev and QA. One of our apps on DEV failed after the upgrade -- I should say the app was ok initially after the server upgrade and the problem only occurred after we edited an simply jsp page and redeployed the app to the DEV server. We found that an older version of a jar file causes the problem in upgraded server environment and problem resolved after we replace the jar file with a new one.
So after QA server was upgraded to the version 18.104.22.168, I expected that app on QA to fail because of that jar file. But it didn't fail. I have the same package (old jar file in it) redeployed to QA server and the app still worked. I am a bit puzzled by that. That is why I am wondering if cache may play a part in this?
