远程调试Java应用程序

本文介绍了远程调试Java应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个在linux机器上运行的java应用程序。我使用以下代码运行java应用程序：

I have a java application running on linux machine. I run the java application using the following:

java myapp -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=4000, suspend=n

我在这台Linux机器上为TCP打开了端口4000。我在Windows XP机器上使用eclipse并尝试连接到此应用程序。我也在Windows中打开了端口。

I have opened port 4000 for TCP on this Linux machine. I use eclipse from Windows XP machine and try to connect to this application. I have opened the port in windows also.

两台机器都在局域网上，但我似乎无法将调试器连接到Java应用程序。我做错了什么？

Both machines are on the LAN but I can't seem to connect the debugger to the Java application. What am I doing wrong?

推荐答案

编辑：我注意到有些人正在切割和粘贴在这里调用。我最初给出的答案仅与OP相关。这是一种更现代的调用方式（包括使用更传统的8000端口）：

I noticed that some people are cutting and pasting the invocation here. The answer I originally gave was relevant for the OP only. Here's a more modern invocation style (including using the more conventional port of 8000):

java -agentlib:jdwp=transport=dt_socket,server=y,address=8000,suspend=n <other arguments>

原始答案如下。

试试这个：

java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=4000,suspend=n myapp

这里有两点：

runjdwp 选项中没有空格。

选项位于类名之前。类名后面的任何参数都是程序的参数！

No spaces in the runjdwp option.

Options come before the class name. Any arguments you have after the class name are arguments to your program!
