Create Web Service System using WSDL URL

Question

Hi,
Please help me create a Web Service System.
Following is the test result when I perform Connection Test after creating a system
Test Connection with Connector
  Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the backend application using the connector defined in this system object
  Results
Retrieval of default alias successful
Connection failed. Make sure that Single Sign-On is configured correctly
Thanks,

Answer 1

Let me reiterate my problem.
I created the System as following
Creating System's Object:
1) Go to System Administration 
2) Go to System Configuration 
3) Go to Portal Content on Object Based Navigation Area (Right Side Panel)
Note:  For avoiding confusion it is recommended to create a folder in which we are creating System Object.
4) Right Click on Portal Content, select New -> System (from Template) 
5) This action will display a new view on right side, now choose Web Service System using WSDL URL radio button from the existing templates. Click Next
6) Give the System Name  i.e. System_WS and System Id  (which are mandatory fields) incase you want to give any brief notes about the system then give it in Description field.  Click Finish.
8) Choose Open the object for editing Click OK. 
9) Now to create a Web Service System, we need WSDL URL. 
10) There are lots of freely available WSDL files on internet, search for any such WSDL file. 
11)  In the Properties area of system give the appropriate WSDL URL
12) Choose System alias, from display menu and give alias as System_WS.
     This alias name will be the name of Web Service System.
I used the following url
http://soap.amazon.com/schemas2/AmazonWebServices.wsdl
After the system is created,
1) Right click on the created system> open > object
2) Drop down for Display options is changed to Connection Tests from what it shows as object
3) Check the check box for the test name Connection Test for Connectors
4) Result shows that the connection failed. The error message was posted in my first question.
Thanks,
