SOAP : it's an message exchange protocol ie., when you invoke the web service your request will be send to the service as SOAP message. and similarly your response will be deliverd from the service as SOAP message. The Soap has two section, header and body. all your requests will be in the soap body.

WSDL : It defines the contract between the service and the client. In the java prospective its the interface, which has the information like what are parameters to send and receive and where the service lies and what is the transport protocol to used ....

UDDI: this is the registry for publish the service either public or private and subscribe the service

For learning the Web service go thro' the edocs of weblogic. and also go thro' some jsr's like jsr-181, jsr-109 and .....

Which API are you using to create the Web Service. All most all the API's gives their own task to create the Client jars from the WSDL file. So create the Jar file from the ant task and use the classes in the Jar.

Eclipse 3.2 / 3.3 and Any Application Server (depends on your EJB Version).
Application Server itself contains the j2ee.jar or any specific vendor jar like weblogic.jar.

Use any ORM framework, so that you can get the database result as java Object.
And use Jax-ws or axis for creating the WS. When the client invoke the service,you internally call the database and get the java object and return to the client.

Verify your web.xml and faces-config.xml files.

What is the version of the Axis and to which version of weblogic, you trying to migrate?

Yes, the server is available. Even I could able to access the WSDL. And is there any extra configuration needed for .NET web service for invoking from other clinet?

A simple .NET webservice deployed in IIS server. Form that wsdl, i have created the stub and proxies (using weblogic 9.2 "clientgen" ant task).
When I try to invoke the service, I get the following error.


Before calling the service !
java.rmi.RemoteException: SOAPFaultException - FaultCode [{http://schemas.xmlsoap.org/soap/envelope/}Server] FaultString [System.Web.Services.Protocols.SoapHeaderException: Server unavailable, please try later ---> System.ApplicationException: An error occured processing an outgoing fault response
--- End of inner exception stack trace ---] FaultActor [http://w2lzkf0p01/ACDR/Service1.asmx]No Detail; nested exception is:
javax.xml.rpc.soap.SOAPFaultException: System.Web.Services.Protocols.SoapHeaderException: Server unavailable, please try later ---> System.ApplicationException: An error occured processing an outgoing fault response
--- End of inner exception stack trace ---


Could anyone help me in this. thanks in advance.

My client code is


public class WindowsClient {

/**
* @param args
*/
public static void main(String[] args) {
String wsdl_path = "http://w2lzkf0p01/ACDR/Service1.asmx?wsdl";

try {

System.out.println("Before calling the service !");
Service1 service1 = new Service1_Impl(wsdl_path);
Service1Soap service1Soap = service1.getService1Soap();
service1Soap.invokeDiadem("a", "b", "c", "d", "e", "f");
System.out.println("Service is Called !");
} catch (ServiceException e) {
System.out.println(e);
} catch (RemoteException e) {
System.out.println(e);
}

}

}
