I am trying to get JPype to pass a String into a Java class main
function. Demonstration code below:

=============JAVA============
package com;

public class JPypeTest {

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

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

===========PYTHON===========
from jpype import *

startJVM("C:/Program Files/Java/jdk1.5.0_12/jre/bin/server/jvm.dll","-
Djava.class.path=C:/jpypetest/test/")

com = JPackage("com");
jp = com.JPypeTest();
jp.printArgument('XXXX');
#WANT TO CALL main("arg") HERE!!!!
shutdownJVM()
===============================

What I want is to be able to call main() with an argument from the
python file (using JPype) and have it echo
args[0]. I can get this to work for printArgument(), but not for
main().

Thanks,
Sarah

Try this:
com.JPypeTest.main("arg")

Thanks for your suggestion, but it doesn't work (produces an error).

Does anybody else have any ideas?

Thanks,
Sarah

This is where you should have copy/pasted the error.

Sorry, no.

Good point Laurent. Here is the error produced when I try to access
main() using
'com.JPypeTest.main("arg")'

The original code is pasted at the top of this thread. I only added
'com.JPypeTest.main("arg")' which causes the error below

-------------ERROR_-------------
File "tester.py", line 10, in <module>
com.JPypeTest.main("arg")
RuntimeError: No matching overloads found. at src/native/common/
jp_method.cpp:121
----------END ERROR-------------

Thanks,
Sarah
