Re: [Wrapper-user] Wrapper classpath on Windows 2000

[Leif M. <le...@ta...>]

John,
It is not a command line length problem. The message you are getting is 
correctly showing
you the full name of the file that could not be loaded. If the command 
line were being
truncated somehow, you wouldn't see that.

What Java version are you running on each of your systems? Are they the 
same?
Run on each system. Verify that is what is being run by the Wrapper on 
your XP system:
C:\WINNT\system32\java.exe -version

I have never tried running with a main class in inner classes. There may 
be some
problems with the way the WrapperStartStopApp class is locating the main 
methods.
Can't think of why the platform would make a difference, but there may 
be some
differences if the Java version is different. Once I have more info, I 
can try to
reproduce it here.

Cheers,
Leif
