Platform: Windows7 32 bit.
Eclipse: Juno with SWT.

I used the deployment wizard as follows:
1. After right-clicking the project in the Java project explorer, I selected 'Export'.
2. In the 'Select' feature, I selected 'Java>Runnable Jar file' and clicked 'Next'.
3. In the 'Runnable Jar File' feature, I selected the correct 'Launch Configuration' and 'Export Destination'. I also selected 'Package required libraries into generated JAR', then clicked 'Finish'.
4. A 'Runnable JAR File Export' popup window appeared to tell me 'The JAR file finished with warnings...' This refers to a few unused variables, which are not a problem.
5. I clicked 'OK', and the wizard disappeared.
6. I navigated to the supposedly executable file on my C: drive. It is listed as an 'Executable jar file' of 15MB with the correct timestamp.
7. I double-clicked the executable jar file, and nothing happened.

My expectation was that step 7 would result in the application launch. What am I doing wrong, or what am I missing?

An executable JAR must nevertheless be launched, I think, even on
Windows. What you have is executed thus:

C:\Users\danny> java -jar project-name.jar

Though a Unix/Linux guy, I've developed a lot on Windows and I am
unfamiliar with any .exe wrapper for Java programs. Stilll, there might
be such a thing and I just don't know about it. I develop only web
applications.
