java doesn't work from cmd

Question

I spent about 5 hours googling, but can't find the solution.

I try to install jperf on all my computers,and all but 2 install perfectly. But those two I can't force to run.

One is XP Pro (like half of my computers), second one is XP home (like other half of my computers)

When I run jperf.bat - the command line window appears and disappears. Then nothing happens.

java.exe is in path - typing java shows the correct result.

edited again

now i can see the errors:

So, what can we do now? What is missing???

Open a command prompt into the directory where you have jperf.bat. Then run it from the command line and you should see a clearer error — Jason Sperske

I see you are using javaw rather than java. I understand javaw is used when you DON'T want any diagnostic output. Try running with java (as opposed to javaw) from the command line as suggested earlier.

Try running the batch file from a command prompt - you can then see the error messages. If necessary enter a sub-shell (i.e. type cmd). Might be a 32 bit / 64 bit Java problem - anyway once you see the error messages it is usually obvious what to do.

It could be you are trying to run a 64 bit app on a 32 bit JVM.

Failing that, I am guessing that swingx-0.9.6.jar is either not present where you say it is or it doesn't contain:

org/jdesktop/swingx/JXTaskPaneContainer

You can inspect the jar using WinZip. Why did you choose this jar (presumably there was a reference somewhere)? If it works on some machines and not others I would assume the jars are different (even though they have the same name). Try copying one of the working jars to one of machines that is hosed and try again, but make sure it is not a 32 v. 64 bit problem.

I just unpack the jperf.zip and install java 7u45 from sun. Everywhere works but two machines
