tomcat jpda 远路调试

tomcat jpda 远程调试
像一些主流的IDE都可以在本地用调试状态运行tomcat，但如何在本地调试其他电脑上的tomcat呢？tomcat可以通过jpda进行远程调试。
我在网上看到一些例子，都是讲怎样改startup.bat(linux下是startup.sh)或者是改catalia.bat( linux下是catalia.sh)。我觉得这样子太有侵入性了，怎样才能不改文件进行远程调试。我用的是tomcat 6.0.18。windows下可以通过命令"catalia.bat jpda start"，用调试状态启动tomcat，linux则是"./catalia.sh jpda start"。我仔细看catalia.bat 和 catalia.sh的区别，bat 里面的默认jpda参数是
JPDA_TRANSPORT  (Optional) JPDA transport used when the "jpda start"
                 command is executed. The default is "dt_shmem".

JPDA_ADDRESS    (Optional) Java runtime options used when the "jpda start"
                  command is executed. The default is "jdbconn".

JPDA_SUSPEND    (Optional) Java runtime options used when the "jpda start"
                 command is executed. Specifies whether JVM should suspend
                  execution immediately after startup. Default is "n".
sh 里面默认jpda参数是
JPDA_TRANSPORT  (Optional) JPDA transport used when the "jpda start"
                  command is executed. The default is "dt_socket".

JPDA_ADDRESS    (Optional) Java runtime options used when the "jpda start"
                   command is executed. The default is 8000.

JPDA_SUSPEND    (Optional) Java runtime options used when the "jpda start"
                   command is executed. Specifies whether JVM should suspend
                 execution immediately after startup. Default is "n".

我测试一下，通过netbeans的调试连接器，远程调试linux下运行的tomcat。
