Question

I run java application that run jetty with port for example 9911.
After I run application I see that the port is already in use :

2012-08-07 10:36:06.848::WARN: failed SslSocketConnector@localhost:9911
java.net.BindException: Address already in use: JVM_Bind

With netstat I get :

TCP    NoamPc:9911            MyPc:0       LISTENING       1436

With tcpView I get :

java.exe  1436    TCP 9999    MyPc    0   LISTENING

The process is run from : C:\dev\jdk1.6\bin\java.exe
in VirtualVM I cannot see any process…

I know that I can use with some other port number,
But my question is how can I check in windows environment, who run/activate process that lock specific port before.
Tnx

I find this useful application – Process Monitor

you can see processes running and executed, with process tree.
You can download it from http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx
