If you decide not to use the .NET SOAP engine, PowerBuilder uses the EasySoap Web service engine. Earlier releases of PowerBuilder supported the EasySoap Web service engine only. Unlike the .NET Web service engine, the EasySoap engine does not support the XML-type array datatype or header sections in SOAP message envelopes. The EasySoap Web service engine is retained for backward compatibility and for use with targets deployed to UNIX machines.
You set the Web service engine that you want to use on the first page of the Web Service Proxy Wizard or on the Web Service tab of the Property sheet for a Web service project. The Use .NET Engine check box is selected by default for new Web service projects. You must clear the check box if you are developing a Web service application that you intend to deploy to UNIX machines.
