无法连接到远程VM。(Failed to connect to remote VM. Connection refused. when trying to debug remote java application in Flash Builder 4.7)

有一次，远程调试用于工作。 但是对于我的生活，我似乎无法弄清楚是什么打破了它。

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

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

在我的flex调试配置中，在左边，我有远程Java应用程序。 在右边，我有Standard（Socket Attach）作为连接类型，127.0.0.1（我也尝试了localhost）作为Host，而8000作为Port。

以下是堆栈跟踪。

！ENTRY org.eclipse.jdt.launching 4 2013-09-03 11：30：49.109！MESSAGE无法连接到远程VM。 拒绝连接。 ！STACK 0 java.net.ConnectException：连接被拒绝：在java.net.PlainSocketImpl.doConnect（未知源）上的java.net.PlainSocketImpl.socketConnect（Native Method）处的java.net.PlainSocketImpl.connectToAddress（未知源）处的at在java.net.java.net.Socket.connect（Unknown Source）上的java.net.Socket.connect（Unknown Source）处的java.net.SocksSocketImpl.connect（Unknown Source）处的java.net.PlainSocketImpl.connect（Unknown Source）。 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（未知来源）

这是调试配置的屏幕快照。

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.

最满意答案

在-vm参数之后，每个调试参数必须放在一行中。 这应该可以做到这一点：

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

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

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

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!
