[Py4j-users] Help Requested: error when accessing jvm for basic sample

[Sean S. <sea...@gm...>]

HI All,
I'm just getting started with Py4J, basically just trying to call a
jar. I'm having trouble with the basic sample however:


>>> from py4j.java_gateway import JavaGateway
>>> gateway = JavaGateway()                   # connect to the JVM
>>> random = gateway.jvm.java.util.Random()   # create a java.util.Random instance
>>> number1 = random.nextInt(10)              # call the Random.nextInt method
>>> number2 = random.nextInt(10)
>>> print(number1,number2)
(2, 7)
>>> addition_app = gateway.entry_point        # get the AdditionApplication instance
>>> addition_app.addition(number1,number2)    # call the addition method
9

I keep getting the following error: [Errno 10061] No connection could
be made because the target machine actively refused it

I'm on python 2.71 for windows i have jre6 se installed have set path.
cheers,
Sean
