Problem with JAR Deployment

Question

Hi,
I knew there are many threads about the deployment to a jar file and problems of missing additional jars used in the project. But I'm facing a problem, which I couldn't solve by reading the threads. Also I've read in Oracle JDeveloper 10g Handbook of OraclePress howto "Create a Java Application JAR File" and hopefully done all necessary steps.
at the moment I've done the following
1. create a new Deployment to JAR
2. enter a name for JAR File: C:\test.jar
3. checked "Include Manifest File"
4. set the Main Class to main.MainFrame
5. create a new File Group "libs" with type Libraries
6. I've selected all jars available in "Filters" (later I will try to minimize the added jars, but for a first try all jars should guarantee that nothing is missing)
7. deployed ma project to jar-file
8. running java.exe -jar C:\test.jar
I get always NoClassDefFoundError ...
Opening the test.jar in JDEveloper I can see all the jars inside it, opening the manifest.MF I see the following:
Manifest-Version: 1.0
Created-by: Oracle Jdeveloper 10.1.3.0.4
Main-Class: main.MainFrame
What else do I have to do to get it running without error???
Thanks for any help - You're helping a despairing person near at the end of all nerves :)

Answer 1

There is an option in Jar deployment profile properties, Additional manifest files to merge...
Add a file such that the contents define your classpath. I have one that looks like this:
Class-Path: lib\frmjdapi.jar lib\support.jar
Make sure the Class-Path is on one line and append a new line to the end. So your final file will contain two lines. first is the classpath and second is just the line feed.
When you opn the Manifest file now, you should see the Class-Path contents added.
Good luck.
