无法连接到远程VM。拒绝连接。尝试在Flash Builder 4.7中调试远程java应用程序时 [英] Failed to connect to remote VM. Connection refused. when trying to debug remote java application in Flash Builder 4.7

问题描述

一点，远程调试工作。但对于我的生活，我似乎无法弄清楚是什么破坏了。

我有一个flex / Java应用程序。有一个包装器启动tomcat服务器。我修改了wrapper.conf文件以包含

-Xdebug -Xrunjdwp：transport = dt_socket，address = 8000，server = y，suspend =在我的flex调试配置中，左边我有远程Java应用程序。在右边，我有标准（套接字附件）作为连接类型，127.0.0.1（我也尝试过本地主机）作为主机，8000作为端口。

以下是堆栈跟踪。

以下是调试配置的屏幕截图。

解决方案

经过多次的斗争，我终于明白了。我不得不进行两个更改。

1. 我添加了tomcat.enable.debug = true到我的catalina.properties文件。



2. 在我的wrapper.conf中，我有以下几行。

   
   
   

   wrapper.java.additional.9 = - Xmx2048m
   wrapper.java.additional.10 = - XX：MaxPermSize = 1024m

我的MaxPermSize设置为比Xmx更小的尺寸。我不得不改变1024到2048.

然后我重新启动了我的tomcat，它的工作，终于！

At one point, the remote debug used to work. But for the life of me, I don't seem to be able to figure out what broke it.

I have a flex/Java application. There is a wrapper that starts the tomcat server. I modified the wrapper.conf file to include

-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n

In my flex debug configurations, on the left, I have Remote Java Application. On the right, I have Standard (Socket Attach) as the connection type, 127.0.0.1 (I have tried localhost too) as Host, and 8000 as Port.

The following is the stack trace.

!ENTRY org.eclipse.jdt.launching 4 113 2013-09-03 11:30:49.109 !MESSAGE Failed to connect to remote VM. Connection refused. !STACK 0 java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.(Unknown Source) at java.net.Socket.(Unknown Source) at org.eclipse.jdi.internal.connect.SocketTransportService$2.run(SocketTransportService.java:136) at java.lang.Thread.run(Unknown Source)

Here is a screen shot of the debug configurations.

解决方案

After much struggles, I finally got it figured out. I had to make two changes.

1. I added tomcat.enable.debug=true to my catalina.properties file.

2. In my wrapper.conf, I had the following lines.

   wrapper.java.additional.9="-Xmx2048m" wrapper.java.additional.10="-XX:MaxPermSize=1024m"

My MaxPermSize was set to a smaller size than Xmx. I had to change that 1024 to 2048.

I then restarted my tomcat and it worked, finally!
