Need help compiling external jar files into my one jar file from cmd line

Question

Here is my problem, let me see if I can explain it right:
I am making a jar file on my development computer that will run my java project. In this java project, it references a couple Java3D jar files. On my development computer, I create the jar file and it runs correctly, but when I move that jar file over to the test computer, the parts of the application needing those Java3D jars are not found in my jar I created. I isolated the problem and it is because those Java3D jar files I needed are not on my test machine. But that is the way I need it to be. I need it so that when I compile all my code on the development machine, I need it to also compile those two Java3D files into my one jar that I move to the test machine. You get what I'm saying? I must do all the compiling from the command line and have only one jar file to put on the test machine that contains all my compiled code and the two Java3D files needed to run some of the applications in the project.
Here a brief sample of what I'm doing:
To compile my java files in my project, I simply to this for all my files:
javac file.java
javac file2.java... and so on for all my java files.
Then I create my jar file:
jar -cfm MyJar.jar manifest.mf file.class
jar -fmu MyJar.jar manifest.mf file2.class... and so on for all my class files.
Also when compiling my jar file, I do this thinking that it would include the two Java3D jars into my one jar file:
jar -fmu MyJar.jar manifest.mf jars/j3d-org-images.jar
jar -fmu MyJar.jar manifest.mf jars/j3d-org.jar
My manifest file looks something like this:
Manifest-Version: 1.0
Main-Class: Main
Class-Path: jars/j3d-org.jar jars/j3d-org-images.jar
Do I have to have that Class-Path in there pointing to those jar files? Those jar files will not exist on my test machine because the directory structure will not be the same. I've tried a manifest without specifying my Class-Path to those jar files, but I get the same problem when I run my application on the part that needs the Java3D files.
The error I am getting is that there is a RasterTextLabel class inside one of those Java3D jar files that my application cannot access because those jar files are not on my test machine.
So basically what I really need to know is how I get those two Java3D jar files compiled into my one jar file that I move to a test machine and run with the following command:
java -jar MyJar.jar
Can anyone help me??
Thanks.

Answer 1

Here what you need is to have all the files present in a single jar file, and the classpath is set properly to the required jar files.
Do the following in steps:
1)
Create a custom manifest file,say mymanifest.mf, with the following contenets, put it in current directory:
Manifest-Version: 1.0
Created-By: 1.4.0_01 (Sun Microsystems Inc.)
main-Class: Main
Class-Path: jars/j3d-org.jar jars/j3d-org-images.jar <press ENTER key>
2)
jar -cfm MyJar.jar manifest.mf file.class
jar -fmu MyJar.jar manifest.mf file2.class... and so on for all class files.
3)
jar -fmu MyJar.jar manifest.mf jars/j3d-org.jar
jar -fmu MyJar.jar manifest.mf jars/j3d-org-images.jar
(Make sure that j3d-org-images.jar and j3d-org.jar are present in a subdirectory called 'jars')
Now you would be able to run,
java -jar myjar.jar
