jemplode won't start

On a fairly new install of WinXP Pro, I can't get jemplode to start. I've got the latest .jar file from jempeg.org and I removed and reinstalled the latest jre from Sun.

When it starts it just puts up the "Reunion Tour" splash screen and stops. The javaw.exe process is not using 100% CPU and allocates about 16 megs of RAM. Nothing happens even after minutes on a fast machine.

I can't really think of anything related that might break it. I do have the Nokia PC Suite software installed which had associated itself with .jar files but I was specifically selecting the Sun java interpreter. After reinstalling the jre it took back the file association anyway.

I've never had a this problem before. Any ideas?

You could try running it from the command line by typing "c:\path\to\java.exe -jar jemplode.jar" and see if it prduces any output.

OK thanks Bitt. This is what I'm getting, but it doesn't mean a hell of a lot to me although a null pointer is obviously a bad thing:

C:\Program Files\Java\jre1.5.0_06\bin>java.exe -jar jemplode.jar

I thought I'd have a look at the source (although I know nothing about java). Unfortunately the link is broken.

It works fine on other machines for me just fine - just not the one I want to use it on. In fact, I'm pretty certain it even worked on this machine at one stage.

Well, it's a problem with the "Look-and-Feel" setting, which I'd suggest you change, except the place to change it is inside the application, which won't open. Under Unix platforms, you could change that by editing the .openrio/jempegrc in your home directory, but I don't know where that would exist under Windows. The registry, maybe? Nope. Looks like "C:\Documents and Settings\<username>\.openrio\jempegrc". Open it with a text editor (like Notepad) and find the "jempeg.lookAndFeel" setting and change it (from "system"?) to "metal". Then try restarting it.

Thanks Bitt. That wasn't it exactly, but you got me on the right track. My Windows user name has a space in it. The .openrio directory was there in the profile but there was no jempegrc file - obviously I haven't run it on this machine before. I removed the .openrio directory and ran it again. It created the directory and that was it.

Anyway, I created a new profile without a space in it and it seems to work fine. However, I'd like to be able to run it under my profile that has a space in it.

I would have thought for sure someone would have run it with a Windows user name with a space in it before.

Thanks for your help Bitt. At least I now know what's wrong.

Just for the reccord, OSX takes the space out of the home directory name if the username has a space. Isn't it nice when things just work.(*)?
