Cool, thanks for helping out. I think I'll incorporate it into the instruction pages.

Work have recently given me a new machine (IBM T40, winXP and no serial ports so I'm using USB adapter), and I'm having no luck getting this working.

Since I worked with computers all day long, and I'd previously set this up on my old machine this looked pretty simple.

I didn't have any luck using the existing java, so I downloaded all the files as specified exactly in the above message and put everything where it is supposed to go but I'm still getting the same old error I got the first time I tried the install ( done the above steps 3 times! ) ...I know it has to be something I'm overlooking.

here is the error message;

Exception in thread "main" java.lang.NoClassDefFoundError: mjljTune-2/0/2/jar

Any help would be appreciated

I don't understand, I'm very commandline oriented, when I try to run the .jar file via the commandline I get the above error, when I double click the .jar from within an explorer window it works!

So entering 'java -jar <the jarfile name>' doesn't work? that's weird. you might want to check to see if the command line is pointing to the old version of java.

At the command line enter
java -version to see what version it comes up with. if it's an old version that could be your problem.

I didn't use the -jar parameter, didn't think I needed it. It works when I use it. Has it always been a requirement even with old 1.1.6ish JDKs (back when I used to do alot more Java stuff).

Thanks.

does this look funky to you brent or neil? I'm trying to run it too and at first I had the same problem as neil so I tried using -jar and gives me this error.

% java -jar mjljTune-2.0.2.jar

Sounds like you don't have the comm.jar file in the same directory as the mjlj JAR file.
