I understand that most people probably use Eclipse IDE to compile this source. I just wanted a neat way of doing it wihtout needing the IDE. As I understand, by adding the attributes to the build-user.xml file the said manifest file is automatically generated by ant. My solution works, but no doubt there are many ways to achieve the same thing.

You normally use http://en.wikipedia.org/wiki/Manifest_file to declare classpath in jars.

Your ide should do that automatically if you use it.

I don't remember how to do it from the command line. IF you need to do it manually the look here http://en.wikipedia.org/wiki/Classpath_%28Java%29#Setting_the_path_in_a_Manifest_file

Just remembered that the reason I wanted to post this was because I kept getting runtime errors, it turns out that when you run java with the -jar commandline option it ignores CLASSPATH environment variable aswell as ignoring the -classpath command line argument, so the only way to get it to work was to include the class path in the manifest of reprap.jar

The error I kept getting was:

Hopefully google will pick this up, and if anyone has the same problem then this post will be of use.

Yes, thats right, I forgot to mention that.

Its not ideal, because as the screws tighten, the L profiles tend to bow in. But it works quite well.

So you are using L profiles with a screw instead of a simple plate to be able to tighten the fit?
