How to trace SOAP message in Eclipse IDE

In SOAP web service, each HTTP request or response encapsulates a SOAP envelope, these messages are easy to trace by using Eclipse IDE, build-in “TCP/IP monitor” tool. The idea is host another server in between the client and server to perform port forward function to intercept the HTTP traffic.

1. Normal SOAP envelope flows

In normal SOAP service, client send a HTTP request to server, and server send back a HTTP response to client directly.


1. Client ----> SOAP envelope ----> Server:9999

2. Server:9999 ----> SOAP envelope ---> Client

2. Intercepted SOAP envelope flows

To intercept SOAP envelope, you can host another server (“TcpMonitorServer”) in between client and server, see new flows :


1. Client ----> SOAP envelope ----> TcpMonitorServer:8888

2. TcpMonitorServer:8888 --> SOAP envelope ---> Server:9999

3. Server:9999 ----> SOAP envelope ---> TcpMonitorServer:8888

4. TcpMonitorServer:8888 ----> SOAP envelope ---> Client
Note
This method required port changed in your web service client.

Eclipse IDE + TCP/IP Monitor

Eclipse IDE comes with a very easy to use traffic interceptor tool, known as “TCP/IP Monitor“. In this tutorial, we show you how to enable this “TCP/IP Monitor” in Eclipse IDE, and also intercept the SOAP messages generated by web service.

Here’s the steps to enable “TCP/IP Monitor” in Eclispe IDE.

1. In IDE, access Windows –> Preferences –> Run/Debug –> TCP/IP Monitor

2. Fill in server information, and choose type = “TCP/IP

eclipse-trace-soap-example2

3. Click on the “start” button to start tracing the web service traffic.

eclipse-trace-soap-example3

4. Show the traced messaged in the “TCP/IP Monitor” view if any.

Note
You can copy this JAX-WS web service example and do the testing yourself.
For Netbean users
In Netbean IDE, you can use TCP monitor to trace SOAP message.

Hi,

While I trace SOAP message in Eclipse IDE for localhost its working fine but i used another IP address it didnt show any trace(request,response).Give a solution for that.

eg:

Local Monitoring port:8888
HostName:Localhost
port:9999
Type:TCP/IP

When using this and running my application in same pc(means localhost) its getting output correct and showing trace(request,response).

But, When i am using the following details TCP/IP monitor

Local Monitoring port:8888
HostName:123.456.7.8
port:9999
Type:TCP/IP

I am getting correct output but i didnt get trace (request,response).Here i deploy my service endpoint in another pc having IP:123.456.7.8 .

What is problem here?

Thanks,

sudheer

Excellent tutorial, this tcp monitor is very helpful. I would suggest that you add the following line of code to the tutorial to show how the client port number changes once the tcp monitor is setup.

URL helloUrl = new URL("http://localhost:8888/ws/hello?wsdl");

Ok I tried your example in my Struts page but it keeps on returning this kind of error

javax.xml.ws.WebServiceException: Undefined port type

why this happens?

I am trying to analyse my SOAP messages using the Eclispe TCP/IP Monitor. However when I see a request there is for example written:

Request: localhost:8888
Size: 1075 (1472) bytes

The type of the monitor is HTTP.

Why is there on value in a bracket and what is this value?
