DIfference between Eclipse Application and Java Application Run Configurations in Eclipse

Dear all,

I'm creating a runnable Jar file, when I try to select the run configuration it only displays Java Run configurations.  The run configuration I'm trying to use is an Eclipse Run Configuration.

What is the difference and workaround?

I haven't noticed this issue before.

Thanks

I think Eclipse Run config is for eclipse applications only i.e eclipse plugin development.

How to convert from Eclipse Run Config to Java Application Run Config?

The difference between the two configurations is JRE, Classpath and Source.

Are the plugins added under the class path?  Any way to copy from the existing run configuration (config.ini) to the java run configuration?

I've copied a portion of the config.ini and added the eclipse launch configuration below.

I'm trying to creating a runnable Jar in order to run the software using a batch file on users machines.  

When I try to select the run configuration after export -> Java -> Runnable Jar etc. it only displays Java Run configurations.   The run configuration for the code is an Eclipse Run Configuration.  I'm trying to find a way to create a Java run configuration because there are many plugins and dependencies.

I've taken over this code and the developer has moved on. So I'm trying to use the config.ini and Eclipse Run Configuration .Launch to make sure I don't miss anything.

Is this an eclipse plugin application?

If you want to create a jar to distribute to users machines, just File > export > Java Jar file. Which will package up your code in a Jar file.

I'm still not clear why you would want to "execute" the jar from eclipse. If thats what you want, then perhaps you could use an external tool config.
Run > External Tools Configuration > program.

I've created a jar to package the code to run on other machines using export > Java> jar.   I'm now having difficulties how to run the jar file.  I've tried:
java -jar slf.jar au.ces.app.Application arg1 arg2 arg1 arg3 arg4
Exception in thread "main" java.lang.NullPointerException
        at sun.launcher.LauncherHelper.getMainClassFromJar(LauncherHelper.java:3
99)
        at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:463)

I wanted to create a runnable jar using an eclipse run configuration because I know run configuration executes the code and has all the plugin dependencies.  But the issue is an Eclipse Run configuration cannot be selected when creating a runnable jar.

I'm not wanting to execute a jar from eclipse.

Check if your java file contain manifest file within META-INF directory. If so, check it has an entry for main class as given below.

Manifest-Version: 1.0
Class-Path: swt.jar
Main-Class: mypackage.MyClassWithMainMethod
(blank line at end of file)
