Java Executable file help?

I hava created a jar file i can run it from my computer doing the following

java -jar filename.jar

But this same program when I click it on a windows machine it does not work saying it cant find main is that a normal behavior.

Note the windows XP machine has only JRE

Also I have only one class and the main method is inside of it.
in the manifest line I just write the name of my class.
thanks

Hi,

Your manifest file should be something like this.

Main-Class: MyClass

and make sure that the text file(Manifest.txt) must end with a new line or carriage return. The last line will not be parsed properly if it does not end with a new line or carriage return

You need to associate the .jar extension with the java (or, more likely, the javaw) command.
