Okay, I've placed our VLTrader installer for IBM Windows JRE 1.6 at
www.cleo.com/web_install/eng/install.exe. You actuall don't need a license for this since the web GUI can be used without a license.
After installing, bring up the native GUI first by running VLTrader.exe. Go to the Web Browser service under the Local Listener in the Active tree. Click on the Advanced tab and turn on "Append service debug to system debug file" and "Create individual client debug files" and click [Apply].
Now start or restart the VLTrader Windows service. Try opening a web GUI session at
http://localhost:5080/VLTrader. It should timeout. The AjaxSwing server-side debug will show up in logs/VLTrader.dbg. As you've noted before, the command line that's used to start up the client agent is in this debug under "cmdLine = ". But no client agent JVMs start and no client-side debug files (logs/HTML*.dbg) are created.
From our testing, it would appear the IBM Windows JRE 1.6 does not like something about the asboot.jar in the bootclasspath and fails to start. But it is failing silently.
