Accessing XI Web Service in Web DynPro

Question

Hi Experts,
         I have a scenario wherein, I will have to access a Web Service that created in XI.
My Finding still now,
1. I have a web service which is created in XI System.
2. Created a Logical Destination in the Visual Administrator. We have given the wsdl URL, system ID, Client and Basic Authentication Information.
3. When we test the Web Service in the Visual Admin, we get a Message Reponse 200, but the content type says Unknown
4. When we test the Web Service in the SOAP Sonar Web Service Testing Tool, we are getting the correct solution
5. After that, we tried creating an Adaptive Web Service Model, using the WSDL URL.
6. When we deploy the application, we get the following error
Exception on creation of service metadata for WS metadata destination 'POItems' and WS interface 'POitem_WS_OUT'. One possible reason is that the metadata destination 'POItems' has not been properly configured; check configuration
When I tried to access a BAPI that is exposed as a Web Service by default, I end up in the following error
Exception on execution of web service with WSDL URL 'http://mycomp01:1001/sap/bc/soap/wsdl11?services=ZBAPI_POITEM_GETLIST&sap-client=800' with operation 'ZBAPI_POITEM_GETLIST' in interface '{urn ap-com ocument ap:rfc:functions}ZBAPI_POITEM_GETLISTPortType'
I have also tried to create a Deployable Web Service using the WSDL file in the Web Service Perspective. Once I deploy the ear file, it appears in the Visual Admin, but when I try testing it I get an error with Response Code 500
Note: I have tried to create an Adaptive Web Service model for the following Link : http://www.webservicex.net/WeatherForecast.asmx?wsdl that is availbale in the net using a logical destination that refers to the same WSDL URL, the application is working fine.
Server/Studio Config details
J2EE - 7.0
NWDS 2004s SP 12
JDK - 1.4.2_09
Please suggest a solution for the above problem or it would be helpful if you can give links that helps in creating a Web DynPro Application to access the XI Web Service. We have followed as per this Link :

Answer 1

Vaishali,
never did this before, but some general ideas:
Do you have an WSDL for that web service? Then simply use your NWDS and select New --> Portal Service --> From WSDL (or similar). What I mean is the following: NWDS can read WSDL files and will automatically generate a proxy for you that actually generates an ordinary portal service. This portal service then can be called by standard means in SAP EP.
