I have created a jar file and linked it to .exe file using the launch4j, it was working in the computer that I created the software, but when i try to distribute the software, The .exe file or .jar file or .jnlp file, none are working. When I double click the .exe file, I will get error 

package.mainclass not found. Program will exit

how to find the error, if it is working in my computer and not working when i distribute it?

  • *"The .exe file or .jar file or .jnlp file,.."* JNLP as in Java Web Start? Provide more details specific to that and I might be able to help you sort it out. – Andrew Thompson Mar 18 '13 at 13:55
  • i have created a project and buid a jar file using the netbeans. and then i used launch4j software to make it as .exe file, where everything works fine in my computer, but when i distrubte/ run in other computer, I am facing the above error. – vijay Mar 18 '13 at 14:00
  • Sure, I saw that the first time you wrote it, in the question. Did you read what I wrote in my comment? To put 'not too fine a point' on it -- I don't give a toss if it fails in Launch4J, but might help you fix the JWS. – Andrew Thompson Mar 18 '13 at 14:02
  • How did you configure Launch4J? Make sure you _don't_ tick the "don't wrap the JAR" box. – Ian Roberts Mar 19 '13 at 17:35
  • i figure out the error, error -> i am running the software with wrong JRE – vijay Mar 20 '13 at 10:26
