Verify that you are using apache Axis 1 for your web service implementation.

Axis clients require a Web Service Description Language (WSDL) file for the initialization.

Verify that a WSDL file is generated for each web service when the Axis server is initialized. The WSDL file for a web service is updated each time when the service is dynamically deployed or undeployed successfully. A WSDL file is required for each web service. Typically, when a web service is made available using Axis, a unique URL is associated with that web service. The URL name is typically http://localhost:8080/usm/services/

webservice

. An example is http://localhost:8080/usm/services/UserService for the web service named UserService. Name your WSDL files using the convention

webservice

.wsdl, where

webservice

is the name of the web service.

Verify that each WSDL file contains the information, including method signatures, required to call currently deployed services. The WSDL files help you to differentiate the following parts of a service:

Abstract functionality description
Concrete details description, such as message format and communication protocol. Examples include SOAP, HTTP, and MIME.

Thus, you can reuse a WSDL file for different types of clients.

If you use a Java program to call the methods, verify that the following jar files are in the class path. These files are installed in USM_HOME/webapps/usm/WEB-INF/lib:

axis.jar
jaxrpc.jar
commons-logging.jar
commons-discovery.jar
wsdl4j.jar
mail.jar
