We are facing a very strange problem.

We are testing a web application with iPlanet 6.1 + JRun + WebLogic 8.1. We have two web servers, web1 and web2 and two app servers, app1 and app2.

Our Login script with one VU(attached) works fine with only web1 and app1 and app2, but gets this error in JRun log with only web2 and app1, app2 and the Robot gets the error page from web server:
</font><blockquote><font size="1" face="Verdana, Arial, Helvetica">code:</font><hr /><pre style="font-size:x-small; font-family: monospace;">12/22 08:32:59 error Requested resource /baliweb_ver_NOV05_UAT_P20_adc/site/lighthorz800/en/html/static/DBSloginBeanInfo.class not found
</pre><hr /></blockquote><font size="2" face="Verdana, Arial, Helvetica">We have compared everything, includes this class file on web1 and web2 and we can't find anything different.

From these test agents, we can Login manually without any problem and see the exact above class file has been downloaded. This is the key point. My question is: what is the difference between running the script and using the browser?

The test machines are with WindowXP and IE6. We are using TeamTest v2002.05.20 + LP8.

This is the error response:
