How can I view the classpath and jvm args of an executing java program in windows

Question

In *nix I just do ps -ef | grep java to see the jvm args and classpath of an executing java program. How can I see it in windows command prompt? I want to see if certain jars are actually in the classpath of a running weblogic server.

Solution 1

From the command line I would use

jinfo < pid >

which will give you this information and more

Solution 2

You can fire up JConsole, connect to the JVM running Weblogic and then navigate to the "VM Summary" tab to inspect the classpath/vm args.

Solution 3

You can write a small application to connect via JMX and query the mbean java.lang.Runtime. It has an attribute "ClassPath".

import java.lang.management.*

ManagementFactory.getRuntimeMXBean().getClassPath()

This was specifically to know if it can be can be done via command prompt in windows.

jmxterm can be used to query the appropriate mbean for classpath.

It is awesome that you can even do this in a debug session using watch parameters.
