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 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.

Answer 1

From the command line I would use

jinfo < pid >

which will give you this information and more

Answer 2

您可以启动JConsole ，连接到运行Weblogic的JVM，然后导航到“VM Summary”选项卡以检查classpath / vm args。

Answer 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()
