jars: creating and adding

I am working on packaging up the ZomB Dashboard bindings for java, and I have two questions: How do you create a jar as a library? and How do you add it to a project so it can use the jar?
When I build a project, it produces a jar file in suit/project_1.0.0.jar. Is this a good jar file? When I drop it on a project, or add it in the ant classpath, it produces errors:

init:
No to.jar.file specified.

From command line,

ant jar-app

to make the jar file

To add the proper syntax highlighting things, you have to add it to the netbeans classpath file, as you have done.

To deploy the library jar with the rest of the code, run

ant deploy -Dutility.jars=myLibrary.jar
