Newbie Question

Hello All

I am new to XI and am trying to learn XI through SAP material. I connect to a remote server and learn but, everytime I connect and start the Integration Builder, it starts the JWS and which in turn downloads the aii_ibdir_client.jar, sapj2eeclient.jar files, and this takes atleast 10 minutes for me (my net connection is slow). Is there a way that I can configure JWS to cache these files and not download the jar files everytime. If there is a way, I would be thankful if anyone can let me know how to do the same.

Thanks in advance.
