I'm trying to create a JAR file that I can then import into other projects.  I know how to create the JAR file, but then when I go to import it into another project it doesn't find it.

Am I missing something?

you should set it as a required library
Project > Project properties > Required libraries > New
make up a name, click add > archive
then find your jar, click OK.

select it in the required libs tab you now see, click OK

and you're set :)

edit: I think I missed an OK somewhere in this post... mm.. you'll find it out I'll guess :)

Perfect!  I'll try that out.

Thanks for your help!

Ok, that works.  However, now it's giving me the error:

RoboRace.jar(CardFactory.java):3: class CardFactory is public, should be declared in a file named CardFactory.java
(source unavailable)

The class CardFactory is public, but I didn't think that would an issue.  How could it expect it to be in its own file if it's compacted into a JAR file?

To explain, CardFactory is one of many public classes included in the package RoboRace.

Any ideas?

actually, I have never been able to compile a project when it gives me that error.. only way I know to solve this is to put it in it's own *.java file.

It should not be an issue however if you have multiple public classes in a Jar file, I have done that before many times and it was never a problem..

btw, you are using your compiled *.class files in the .jar instead of the *.java files you may have? (I presume you are, but little checking doesn't hurt anybody)

I think I am.  Should I be in order for this to work?

To clarify:  I need to use the .class files, NOT the .java files, is this correct?

yes

Sorry to keep asking questions, but how do I choose to use the .class files instead?  When I click on the tool Create JAR file it just creates it by adding all classes in the project.

Actually, I figured it out.  I was missing the "package RoboRace" in the new project.

Thanks for all your help!

make sure that you have JC set up to use another directory for class files than for source files, then in the tool options, set the initial directory to: "$[OutputPath]"

So you use the .class files... That could explain why jar.exe ate my source code....  Oops.  Had to remake an entire file (luckily it only changed one source file into unreadable byte code.  It could have been much worse...)
