Large project in JBuilder 2007... How do I create an executable JAR?

Question

First, I've googled quite a bit and keep getting thiings about "Jbuilder Application Wizard", etc... Well, I don't see any "wizard" menu in the version of JBuilder I'm using!
I'm using JBuilder 2007 Enterprise edition, however it's a trial version apparently. I'm not sure if that matters, and perhaps the functionality was taken out with the trial version..
Anyway, the issue is that I have a multi class (with one main function) program that I want to run (it's a command line based application) as an executable JAR file. The program uses LOTS of include statements including quite a few custom libraries ("external JARs") that I had to import.
Basically I want the application to do exactly what it does now when I hit the ol' "RUN" button. Except I want to be able to run it from a batch file with "java -jar (or whatever) myProgram".
Anybody have any experience with this type of thing?

OK, here's what I've got:
I've got a jar file that contains:
1. a folder "importQD"
2. a folder called META-INF
3. a .classpath file
4. a .project file
Inside the importQD folder are my three .class files that are the classes I created myself.
Inside the META-INF folder is the MANIFEST.MF file which looks like:
Manifest-Version: 1.0
Main-Class: importQD.ImportQDInside the .classpath file we have:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
     <classpathentry kind="src" path=""/>
     <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
     <classpathentry kind="lib" path="C:\Programs\CMQualityDocumentImport\CMUploadInterface83.jar"/>
     <classpathentry kind="lib" path="C:\Programs\CMQualityDocumentImport\DBCon.jar"/>
     <classpathentry kind="lib" path="C:\Programs\CMQualityDocumentImport\SENAeMail.jar"/>
     <classpathentry kind="lib" path="C:\Programs\CMQualityDocumentImport\SENAFileHandler.jar"/>
     <classpathentry kind="output" path=""/>
</classpath>NOTE: All of the paths point at the .jar files as they are located on the machine the final version will be running on.
Inside the .project file we have:
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
     <name>importOldQD</name>

     <buildSpec>
          <buildCommand>
               <name>org.eclipse.jdt.core.javabuilder</name>
               <arguments>
               </arguments>
          </buildCommand>
     </buildSpec>
     <natures>
          <nature>org.eclipse.jdt.core.javanature</nature>
     </natures>
</projectDescription>Now, it would make sense to me that this should be all good to go, and that I should be able to run this via a command line now. When I try
java -jar importQD.jar I get a ton of various errors such as "Exception in thread "main" java.lang.UnsupportedClassVersionError: importQD/importQD (unsupported major.minor version 49.0) + a nice stack trace with a bunch of java.lang and java.net references.
What am I doing wrong?
