The following are the conditions for the Web Service Implementation Class:

• You must implement all the methods of SEI. If all the methods are not implemented, an error message is output to the standard error output and log (KDJW61011-E).
• As a Web Service operation, you cannot define the finalize method that overrides the finalize method of the Object class. If such a method is defined, an error message is output to the standard error output and log (KDJW61012-E).
• You must define a public default constructor. If such a constructor is not defined, an error message is output to the standard error output and log and the error is notified to the apt command (KDJW61013-E).
• You must code the javax.jws.WebService annotation. If the javax.jws.WebService annotation is not coded, the class is determined as a non-Web Service Implementation Class. If it is determined that the Web Service Implementation Class does not exist, a warning message is output (KDJW61001-W).
• The javax.jws.WebService annotation can be defined using a static inner class. If a non-static inner class is used, an error message is output to the standard error output and log (KDJW61015-E).
• Set the access modifier of the Web Service Implementation Class to public. You cannot specify final and abstract. If a value other than public is specified, an error message is output to the standard error output and log (KDJW61016-E).
• The Web Service Implementation Class might perform implements for SEI. If you are writing implements, and the -sourcepath option is specified when the apt command is executed, you must specify both SEI and the Web Service Implementation Class in the argument. If implements is not performed and SEI is not specified in the argument of the apt command, the SEI information is only referenced by the endpointInterface element of the javax.jws.WebService annotation, but is not included as a target for compilation, so the SEI class file is not generated.

In the mapping of the Web Service Implementation Class to SEI, you can use the endpointInterface element of the javax.jws.WebService annotation to link the Web Service Implementation Class and SEI.

When only the Web Service Implementation Class is defined, the endpointInterface element is not used. In this case, the abstract information defined in SEI is extracted from the information in the Web Service Implementation Class and is assumed that a virtual SEI exists (implicit SEI).

For details about the endpointInterface element of the javax.jws.WebService annotation, see 16.2.9 javax.jws.WebService annotation.
