The organization I work for uses a centralized web-based Oracle (v10g) accounting program to monitor it's worldwide inventory. Our network has very strong firewalls and uses a lot of security software to insure network integrity. Users navigate to a portal website and login to their account where they post transactions and such. When users login and initiate a session we use Microsoft VM to create the virtual environment where we communicate with the accounting program. Microsoft VM works well in our environment and provides quick response times (seconds) as transactions are posted.

Understanding the real possibility that Microsoft VM might go away in the not so distant future we tried using Java 2 (Standard Edition) v1.4.2_13 (build-B06) to create the virtual environment and connect to our accounts. The response time was incredibly slow, it took minutes for the system to transition from screen to screen or provide any response to input.

As a test I bypassed our network and used a standard commercial ISP (cable) connection and Java 2 (Standard Edition) v1.4.2_13 (build-B06) to create the virtual environment then logged into my account. The response time I experienced using this connection was very fast.

My question is: How/why do the security settings of our network affect the system response time when using Java to create the virtual environment? 

Thanks for your help

Sorry, I don't know the answer to your problrm, but it sounds like it may be an issue with the Java security manager, and I would suggest that you investigate that area.

Have you tried running Java 5 instead of 1.4? There are a lot of speed improvements in this version that may help.

Thanks for the reply. I looked at some of the Sun tech articles about Java Security Manager and not being the webmaster I don't completely understand all the action required to fine tune the Java security manager, and I don't have the access either 

I have not tried running JSE2 ver 5. Do you know if Ver 5 has different ways of handling or working around the security manager?
