Debugging WebDB listener?

Question

Hello,
for customer support I maintain a (frozen) development environment using Forms 6i and WebDB listener on Win2K. This has been stable for years... After recent installation of UMTS hard- and software suddenly the connection between WebDB listener and JInitiator 1.3.1.17 gets broken. I am able to connect to the forms server, but the JAR files are no longer downloaded correctly. They cannot be cached anymore:
Downloading http://dbmw1:88/forms60java/f60all_jinit.jar to JAR cache
java.net.SocketException: Connection reset by peer: JVM_recv in socket input stream read
     at java.net.SocketInputStream.socketRead(Native Method)
     at java.net.SocketInputStream.read(Unknown Source)
WARNING: Unable to cache http://dbmw1:88/forms60java/f60all_jinit.jar
connectMode=Socket
serverHost=dbmw1
serverPort=9000
Turning off caching does not solve the problem as certain classes are not found.
I see that the above JAR file is transferred to the IE cache with the correct size, but not to the JInitiator cache. The WebDB listener creates many temporary files in C:\ where they did not show up before, one file having the size of the desired JAR file.
I tried several things to track down the problem:
1. Run SysInternals RegMon and FileMon -> no further hint what might be wrong.
2. Deinstall UMTS software -> problem persists.
3. Reinstall JInitiator -> did not help.
4. Twist settings for JIT and caching -> did not help.
5. Increase debug levels with JInitiator -> did not yield useful information.
6. Increase logging information of WebDB listener -> same result.
7. Debug running listener process with WinDbg -> did not work.
8. Install UMTS stuff on other machine and track installation with InCtrl5 -> Critical changes could not be identified. Some DLLs installed, some REG keys modified (TCPIP service).
Did anyone experience similar problems with WebDb listener? Especially the temporary files in C:\ are suspicous. I know that the WebDB listener solution is outdated and I might try to get Apache working with Forms 6i but I hope to find that small screw that needs to be twisted half so that my environment will be operable again. And no, reverting my system on behalf of a tape backup is not a valid solution as I depend on the UMTS networking for the future.
Thank you in advance,
Lars

I still have a problem getting this to work, maybe I
misunderstood your answer, but I have:
LD_LIBRARY_PATH=/fsdata1/apps/oracle/product/8.0.5/lib:/lib:/usr/lib
for my LD_LIBRARY_PATH and I still can't get it to work. Please
be more specific.
Thanks James
