Using WST, you can create a Web service from an EAServer component and use SOAP to expose it across your firewall. You can select any components in EAServer for a Web service that have return values or parameters of supported datatypes. The components you select for a Web service must be installed in EAServer.
Web services use XML to transfer data between service endpoints. WST includes standard mappings for some basic Java datatypes to XML and vice versa. It also allows you to create user-defined datatypes and mappings for complex datatypes.
