Enterprise Portal has implemented Web service support using Apache SOAP 2.3.1, and has tested it with the client side of the same version. EP has also successfully performed compatibility tests with Apache Axis.

Enterprise Portal allows you to create Web services elements and incorporate those elements into portlets. An example of a Web service might be weather conditions that are returned based on postal code, or stock quote results based on company symbols.
You create Web service elements that use standard WSDL files or service keys (globally unique identifiers that refer to services published in a UDDI Business Registry), then add the elements to portlets that execute local or remote Web services to extract and display portlet content.
Enterprise Portal also lets you create Web services portlets and publish the portlets as Web services to any of these UDDI registries—IBM test, IBM public, TrySybase, and Microsoft test.
