"Launch Configuration" Shows up Blank When Trying to Export Runnable Jar?

Question

Hey everyone,

I've gotten this to work in the past, but now whenever I choose File > Export... > Runnable JAR File and select the drop-down menu "Launch Configuration", all I get is a blank bar.

How can I get my main class to show up?

Many Thanks,

Justian

Answer 1

This "launch configuration" thingie is all fine and good, but you probably just want to specify a main class. One of the pages of the "export" dialog will let you browse for and specify that main class, without the need to go looking for an appropriate configuration. That's how I do it.

EDIT

What I do is

File | Export | Java | Jar File

Then I select the stuff I want exported.

Next | Next and I get a chance to specify my main file.

On the class you want to have main(...) executed in, choose Run->Run and run your program.

This process creates a launch configuration you can use (and save too, if you make it shared)
