remote tomcat server error

hi guys,

we are developing a web application that we test on both a local tomcat server (version 5.0) and also on a remote tomcat server (same version).

in first versions of application things were ok on both local & remote servers-

after we added an applet to our application-and this applet is not loaded until user logs in to our web app system..

now when we tested latest ver on the local server things look OK.

but the problem is that -on our remote server-the index.jsp file doesn't display at all -even before any call to applet & we get the below exception .

the other annoying problem is that our ISP said they couldn't provide log files of tomcat ...

i can't figure out the cause of this obscure error. any Ideas guys ?

thanks.
