Did you create the jar file using a manifest file?

e.g. >jar cvfm myjar.jar manifest.mf *.class

[Ezzaral]

Did you specify the main class?

[vinod_javas]

just check out the manifest file

In that manifest file specify your main class correctly. then it will work fine

as I describe I am using netbeans and when I try to modify the netbeans created manifest.mf and compile it . and then try to compile it complaines "corrupted file" when trying to run double clicking the jar file .

guys thanks very much I got the solution . in netbeans5.5 simply in the project properties select the run panel and enter the main class name then build the project that is all .

[peter_budo]

That is fine but you should also learn how to do it from command line as you may not always have NetBeans
