Folks,

Paul Furbacher has discovered a possible solution for including dependencies i.e. JavaHelp in jar files. I have listed his solution below.

But I do have a question Paul.

I successfully completed steps 1-4 (below) but on step 5, after I rebuild my project and my application archive I expand "myapp.jar" but failed to see the "jh.jar". How can i copy over "jh.jar" to "myapp.jar"?

Paul Furbacher solutions:

Why does this happen in your case? If you look
at the application JAR you made by double-clicking
on its node in the Project Pane, you'll see that
the jh.jar has been unpacked and all its files
have been packed into your JAR. Bad news. You cannot unpack the jh.jar and then include those classes in your application JAR.
This causes a security exception, which then causes
the program to abort.

Running it from *within* JBuilder catches an
exception which you probably weren't seeing:
a "SecurityException". From the command line,
you probably only saw the "Could not find main
class. Program will exit." message which I also
see in a separate window which opens *behind*
JBuilder (not very useful!).

Good news: you can add the jh.jar as a JAR
into your application archive by employing
a few straightforward remedies in JBuilder.

1. Exclude the JavaHelp library in the "Dependencies"
page of the Application archive's properties. Select
"Never include ...."

2. Add a Directory View to the project in the Project
Pane. The target directory is the JavaHelp/lib folder.
Set the filtering to "Use: Wildcards" with file pattern
set to "jh.*" (without the double-quotes which I use
here to delineate the pattern). OK.

3. Right-click on the "jh.jar" node in that directory
view. Select "Properties...", and just under "Build"
select "Copy". Don't select the "Copy" to the right
of the list down below.

4. Clean the project, and if necessary clean your
application archive node. Rebuild the project,
and if necessary, rebuild your archive node.

5. Expand the JAR node inside the archive node.
You should see

myapp.jar
/META-INF
/your_top_leve_package
- jh.jar

Run this. It should succeed.
