I am using following code Snippet to invoke the function present in jar file. but i am unable to connect the class.

Development Env:
Python: Python27,32bit jpype Version(JPype-0.5.4.2.win32-py2.7.exe)

Java Code:

public class Samp {

     public Samp() {
        super();
    }
    public String sayHi()
    {
        return("Hello");
    }
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        System.out.println ("Hello world");
    }

    public static int add(int a, int b)
    {
        return(a+b);
    }
}

C:\temp\tem\samp.jar Jar file is presen in that directory. I am Connecting jar file using below code.

python Code:

>>import jpype
>>jpype.startJVM(jpype.getDefaultJVMPath(), '-ea', '-     Djava.class.path=c:\\temp\\tem')

At the fourth row you want to do

>>> a = A()

and then

>>> print a.sayHi()
