Jar Files

[Alan]

Hello everybody
I am working with JBuilder 2005 and I need to generate an jar executable from my application. I have been searched and I've found that I have to create a main.mf file and the content of the file must be:

Main-class: classMain

after that in command line I have to do this:


“C:\filesprogram\Java\jdk1.5.0_06\bin\jar” cvfm file.jar Main.mf *.class

It work, it creates me a jar file, but when I execute in my application:


Failed to load Main-Class manifest attribue from
application rout

I dont know why, do you know?
I hope so!
thank you

First, open that jar file with winzip/winrar and see if manifest file is there. Then check your main class (The class which has the "static main" method). You should write it with its package name. So if it is class X in Y package, you should write "Y.X" in your manifest file as the Main-Class.

Read the tutorial below for more information:

First the file is manifest.mf
This file must content the following line


Main-Class: MyPackage.MyClass

If your applet is inside a JAR file, you just need to point to the JAR file from your html file.
