How to remotely debug the webapplication running on tomcat service?
提问by M Sach
I have my webapplication on tomcat 6at serverA. I am running the tomcatas service i.e thru tomcat6w.exelying under <tomcat_home>/binfolder. To remotely debug the
weabbplication i have added below lines as suggested on different blog/sites on web in different line witout space at end. Mentioned the port as 8443 as application is running on same port.
我在 serverA 上有我的 web 应用tomcat 6程序。我正在运行tomcat作为服务，即通过tomcat6w.exe位于<tomcat_home>/bin文件夹下。为了远程调试 web 应用程序，我在网络上的不同博客/网站上的建议下添加了以下行，最后一行没有空格。提到端口为 8443，因为应用程序在同一端口上运行。
-Xdebug-Xrunjdwp:transport=dt_socket,address=8443,server=y,suspend=n
Now thru eclipseon server B i mentioned host as serverA and port 8443 and click debug. After 2-3 minutes it establishes connection without giving any error.But now
when i hit webapplication url in IEit does not show up and says IEcan not display the webpage. But as soon as i remove the above mentioned debug parameters
and hit the url, application works fine. I am not getting how should i debug the application when tomcat is running as window service?
现在通过eclipse服务器 B 我提到主机作为 serverA 和端口 8443 并单击调试。2-3 分钟后，它建立连接而没有给出任何错误。但是现在当我点击 webapplication url 时，IE它没有显示并说IE无法显示网页。但是一旦我删除了上面提到的调试参数并点击了 url，应用程序就可以正常工作。当 tomcat 作为窗口服务运行时，我不知道应该如何调试应用程序？
For Information Below are the parameters when i double click the tomcat service
以下是我双击tomcat服务时的参数

you can pass JVM options using JvmOptionsparameter:
您可以使用JvmOptions参数传递 JVM 选项：
tomcat.exe //TS// ++JvmOptions -Xdebug;-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044
or
或者
tomcat.exe //RS// ++JvmOptions -Xdebug;-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044

When I need to remotely debug an application that is deployed on Tomcat, I usually start the server through the Catalina.bat script, not as a Windows service. Actually, to enable remote debugging, you're supposed to provide the JPDA arguments when executing the catalina.bat script :
当我需要远程调试部署在 Tomcat 上的应用程序时，我通常通过 Catalina.bat 脚本启动服务器，而不是作为 Windows 服务。实际上，要启用远程调试，您应该在执行 catalina.bat 脚本时提供 JPDA 参数：
catalina jpda start
卡特琳娜 jpda 开始
If you really need to start your server as a service, you could try to edit its definition so that you also provide the JPDA argument to it.
如果您确实需要将您的服务器作为服务启动，您可以尝试编辑它的定义，以便您也向它提供 JPDA 参数。
Yo could as well stop your Tomcat service and just start the server by executing the catalina.bat script.
你也可以停止你的 Tomcat 服务，然后通过执行 catalina.bat 脚本来启动服务器。
Hope that'll help.
希望这会有所帮助。
