Problem Executing Batch File

Question

I wrote out a java class that I tried using cfobject to call. It didn't work. So I wrote a batch file to call the java class.  The batch file works, but NOt when I have coldfusion call it. Nothing happens, no error... nothing.  I thought it might be a permissions issue, but I tried changing permissions for coldfusion although I may have doneit wrong since I'm not too familiar with Vista.  Can anyone offer advice on what I can do.  Its a simple java class and I can't get it to run.  no errors in the log.  There isn't much for me to go on.  All I know is that the class and batch file work fine if Coldfusion doesn't call them.

To limit the problems with the class itself and cfobject, I've created a batch file to run the class.  The batch file runs the class fine, so long as I execute the batch via command line.  But coldfusion doesn't execute the batch with cfexecute.  the same exact problem with absolutely no error messages.
Unfortunately, cfexecute is not the easiest tag to debug. In my experience sometimes it confuses more than clarifies.  But trying it is not a bad idea from a troubleshooting point of view.
However,  if I create a java class in the same folder that doesn't write to the system and only returns variables, it works fine.  This indicates the class path is set correctly and that cfobject does work.
Yes, I would agree.
It does sound like it might be a permissions issue. But I have little experience with Vista, so there may well be another cause.  Since it sounds like you are just testing a very simple java class, can you post the code for the class itself as well as the exact cfexecute code you are using? I could test it on another operating system. Just to see if there is some obvious problem.

From the 100's of pages I've read online with people with similar problems, this seems to be a permissions issue.  however, I've set Coldfusion to run as me, the administrator and only person who uses this computer.  It is no longer running as local system.
However, this didn't fix anything.  My only guess is that perhaps I've no set it to run as me correctly.  But I have no way of testing this.  Windows logs show no error messages either.  Is there any way to have coldfusion show me what user its trying to execute the batch as.
I believe the user account can be obtained from the java system properties.  Try:
<cfset sys = createObject("java", "java.lang.System")>
<cfoutput>
   <b>user.name</b> = #sys.getProperty("user.name", "not found")#<hr>
   <b>coldfusion.classPath</b> = #sys.getProperty("coldfusion.classPath")#<br>
</cfoutput>
