Question

I have 2 classes within same package. Both classes have main method in them. Now I want to build a jar file. I want to build 2 jar files which use different main functions as default main.

eg

class A
{
  public static void main(String args[])
  {
    //do something
  }
}

class B
{
  public static void main(String args[])
  {
    //do something
  }
}

How do I do it in NetBeans IDE?

I found the answer.
U can do it easily in netbeans:
1)right click on project >properties > run > select the class frm and drop down list. So simple in netbeans. Netbeans rocks!

Answer 1

In the jar file you could just add this to your manifest.mft

Main-Class : A

The jar file would then be executable and would call the correct main.

On how to do this in Netbeans you can look at this:
