Title: RE: TcpTunnelGui program

Hi Jody,

With the command line:

java org.apache.soap.util.net.TcpTunnelGui 8082 localhost 8080

the TcpTunnelGui listen for HTTP resquests on 8082 port (showing the SOAP request on the left scrolled window of the TcpTunnelGUI) and redirects the request from the port 8082 to the port 8080 where the servelt engine is listening.

So, if you want to use this debugging tool (andi suggest to use it) your SOAP clients must send its requests to the port 8082. Thus, with the AdressBook sample one of command lines should be:

java samples.addressbook.GetAddress http://localhost:8082/soap/servlet/rpcrouter "John B. Good"

This way YOU are telling to the SOAP client to send the data to the port 8082.

And if you use the command line:

java samples.addressbook.GetAddress http://localhost:8080/soap/servlet/rpcrouter "John B. Good"

WITH the TcPTunnelGui Tool running, it won´t listen any thing (it listen on 8082 only!) but the servlet engine will and the request will work.

If you use this command line:

java samples.addressbook.GetAddress http://localhost:8082/soap/servlet/rpcrouter "John B. Good"

WITHOUT the TcpTunnelGui running, there isn´t some listener on 8082 port, so the request won´t work.

I had the same confusion. Hope this help you!

Regards,

E.Y.

Thanks to Gregg and Sri for your help but I am still confused about the open port.
Gregg: in your example of the open port of 8091, TcpTunnelGui is listening on port 8091 but what is telling SOAP to send data to that port?

Putting an unused port in the command line of TcpTunnelGui worked because the program stays running. When I use my machine as both soap server and soap client or just as a soap client, nothing is displayed in the program but I know data is sent and received.

You are trying to talk into and send out of the same port number. This ties
up the port for either the input or output and then the attempt to use it
for output or input respectively gives a Bind exception because the port is
already in use. Any time you try and use any port that is already in use,
you will see this exception.

The tunnel works by having one end connected to the port your trying to
send data out to and another port sitting open to receive input (similar in
concept to how UNIX command tee works). If you were trying to send output
to a server located on host CorePortal10 at port 8090, and you wanted to
send input on an OPEN---unused---port of say, 8091, then you would use the
following command when sitting in the directory containing the soap.jar
file:

java -cp soap.jar org.apache.soap.util.net.TcpTunnelGui 8091 CorePortal10 8090

Note that:

E:\LocalCVSRepository\SourceCode\jars>java -cp soap.jar org.apache.soap.util.net.TcpTunnelGui

provides:

Usage: java TcpTunnelGui listenport tunnelhost tunnelport

Subject:  TcpTunnelGui program

Hi, I am new to Soap and Java.

My need is to have a Java Soap client talking to a MS Soap Server.
I am having trouble with accessing the MS Soap Server (I will be sending
that problem shortly).
I am using JRun which defaults to port 8100.
My computer name is CorePortal10.
When I want to run the rpcrouter:
http://CorePortal10:8100/soap/servlet/rpcrouter

For debugging purposes, I want to use TcpTunnelGui but I am not sure of the
parameters that I need to pass to it.

I tried running the following command from the DOS prompt:
java org.apache.soap.util.net.TcpTunnelGui 8100 CorePortal10 8100

The program is only displayed for a moment then exits and displays the
following error:
java.net.BindException: Address in use: JVM_Bind
       at java.net.PlainSocketImpl.socketBind(Native Method)
       at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:397)
       at java.net.ServerSocket.<init>(ServerSocket.java:170)
       at java.net.ServerSocket.<init>(ServerSocket.java:82)
       at
org.apache.soap.util.net.TcpTunnelGui$3.run(TcpTunnelGui.java:185)

Thanks for any help.
