Python JPype importin Java class get JVM mismatch

Question

I am trying to load JAR file to my python program and use the jar classes and functions. I'm using:

• Java 1.8.0_311 32bit
• Python 3.8.10 64bit

my code looks like:

import jpype
import jpype.imports
from jpype.types import *
classPath = "-Djava.class.path='assets/JAR.jar'"
javaClass = jpype.startJVM(jpype.getDefaultJVMPath(), classPath)

i got an exception:

jpype._jvmfinder.JVMNotSupportedException: JVM mismatch, python is 64 bit and JVM is 32 bit.

well its pretty obvious that the exception is the difference between python's and java's enviroments.

Does it have a workaround?

Answer 1

You have two options:

• Install and use Python 3.8.10 32bit (together with Java 1.8.0_311 32bit) instead of Python 3.8.10 64bit
• Install and use Java 1.8.0_311 64bit (together with Python 3.8.10 64bit) instead of Java 1.8.0_311 32bit
