Call Java Methods from Python Script

[hofsoc20]

Hi,

I am trying to call java methods from a python script. Jython is not an option. I have looked at using Jpype. Below is my code thus far:

Jpype.py

from jpype import *

startJVM("C:\Program Files\Java\jdk1.6.0_12\jre\bin\client", "-ea", "-Djava.class.path=%s" % classpath)
com =JPackage("CallJavaFromPython")
jp = com.Jpype1()
jp.printArgument("XXX")
shutdownJVM()

=============== =============== =============== ===== =

Jpype1.class

package CallJavaFromPython;

public class Jpype1 {

public static void main(String args[]){
System.out.println(args[0]);
}

public void printArgument(String arg){
System.out.println(arg);
}

}

=============== =============== =============== ===== =

Error message i am getting when I try to run the python script is :

NameError: name 'startJVM' is not defined


has anyone come across this before?

Thanks in advance...

It's probably because you named your own program Jpype.py which is not a good idea. Thus the line:

from jpype import *

does not do what you expect.
