如何在Java Web Start（JNLP）下调试应用程序？ [英] How can I debug applications under Java Web Start (JNLP)?

问题描述

我知道如何使用Eclipse调试远程Java VM，但是如何使用Java Web Start程序来实现。我有一个问题，只发生在Java Web Start。它必须与安全相关。

我需要一个可以与当前Java VM一起使用的解决方案，如1.6.0_12。

解决方案

与要远程调试的任何其他Java进程完全一样：您必须为VM设置一些参数（ -Xdebug -Xnoagent -Xrunjdwp：transport = dt_socket，server = n，suspend = y，address = 12345
），然后连接到给定的端口。在Java webstart 6.0中，可以通过环境变量JAVAWS_VM_ARGS在早期版本中使用-J选项。查看详情 here 。

I know how I can debug a remote Java VM with Eclipse, but how can I do it with a Java Web Start program. I have a problem that only occurs in Java Web Start. It must be security related.

I need a solution that will work with a current Java VM like 1.6.0_12.

解决方案

It's quite the same like with any other Java process you want to debug remotely: You have to set up some arguments for the VM (-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=n,suspend=y,address=12345 ) and then connect to the given port. In Java webstart 6.0 this can be done with the -J option, in earlier version via environment variable JAVAWS_VM_ARGS. See details here.
