Re: Newbie Eclipse question: Exported jar file does nothing upon execution

Hi all. I'm trying to learn the ropes of how to create an executable
jar from Eclipse. I believe I exported one successfully--I selected
the correct source & main class, and Eclipse reported that the file
was created successfully. However, when I try to execute it, nothing
happens. That is, it acts like some kind of no-op executable.

Any ideas?

Andrew identified the most likely cause.

One way to make error messages visible is to execute the Jar from a command prompt.

In Windows XP: click "Start", "Run", type "cmd" and press enter.

Check the Java runtime is in your path
java -version

Then type a command like
java -jar MyJar.jar
