When you generate Java™ code, the j2eeLevel build descriptor option specifies the J2EE level in the application server to which an EGL Web service is deployed.
This build descriptor option is used with the serverType build descriptor option, if the value of that option refers to Apache Tomcat or WebSphere® Application Server. If the j2eeLevel build descriptor option is not specified, the default is determined by the value of the serverType build descriptor option.
