The build descriptor option serverTypeidentifies the type of Web Application Server in which your output will be deployed. The option is used to create appropriate output when you generate either an EGL-written Web service or a service binding library that binds to a Web service (which may or may not be written with EGL).
The appropriate setting depends on the Web application server on which you intend to deploy the generated output.
This build descriptor option is used with option J2EELevel.
