problem with jar file

[rvy2k]

When I double click on my jar file, I get the foolowing error:

"Could not find the main class. Program will exit!"

I tried
% javaw My JarFile
and it launches fine.

Anybody had the same problem?

Thanks

Did you configure the Manifest correctly (ie did you set the Main-Class)? Wushutwist

i think ...


Manifest-Version: 1.0
Name: Me
Main-Class: HelloWorld

Hurrah I got the Probs.

When you use Javaw ClassName MyJarName.
In the ClassName class u don't have any main method to be invoked. That is the error it is raising when you try to run a class from the jar.

Please check up whether that class has main method or not.
Please check for it and run
