Of the public methods in the Web Service Implementation Class, the public methods that you do not want to make public as an operation can be excluded from the mapped operations by annotating the method with the javax.jws.WebMethod annotation where the element value of the exclude element is true. For methods in an inherited parent class, that method is overridden and can be excluded from the mapped operations by annotating the method with the javax.jws.WebMethod annotation where the element value of the exclude element is true.

The precautions for specifying the exclude element are as follows:

• If public methods do not exist due to exclusion from the mapped operations, an error message is output to the standard error output and log and the processing ends (KDJW61093-E).
• If true is specified in the element value of this element in the Web Service Implementation Class, other elements cannot be specified in the javax.jws.WebMethod annotation of the Web Service Implementation Class. If other elements are specified, an error message is output to the standard error output and logs (KDJW61010-E).
• If this element is specified in SEI, specify false in the element value. If you specify true, an error message is output to the standard error output and logs (KDJW61021-E).
• If the parent class methods are overridden in the Web Service Implementation Class and if this element is specified in both the parent class and the Web Service Implementation Class (child class), the element specified in the Web Service Implementation Class (child class) gets priority.
• If the endpointInterface element of the javax.jws.WebService annotation is not specified in the Web Service Implementation Class, all the public methods, to which the static modifier or final modifier of the Web Service Implementation Class is not applied, are mapped to an implicit SEI. Also, even if one javax.jws.WebMethod annotation where the exclude element is not true is specified in the public methods, to which the static modifier or final modifier of the Web Service Implementation Class is not applied, the methods of the Web Service Implementation Class that fulfill the conditions in the following table are mapped to an implicit SEI.
  

  Table 16-13 Specification of annotations and mapping to implicit SEI

  No.	Methods of the Web Service Implementation Class (WebMethod annotation)	Methods in implicit SEI
  1	No	Not mapped.
  2	Yes (without exclude element)	Not mapped.
  3	exclude=false	Not mapped.
  4	exclude=true	Not mapped.

• If the endpointInterface element of the javax.jws.WebService annotation is not specified in the Web Service Implementation Class and if the javax.jws.WebMethod annotation where the exclude element is not true is specified in the public methods, to which the static modifier or final modifier of the Web Service Implementation Class has been applied, the error message (KDJW61102-E) is output to the standard error output and log.

The operationName element is specified when you customize the mapping for the operation name. If you specify the element value in the operationName element, you can customize the message name that has the operation name in the default mapping value. For the non-wrapper style, you can also customize the global element name and part name.

The precautions for specifying the operationName element are as follows:

• Specify the operationName element using one-byte alphanumeric characters and underscore (_). If other characters are specified, the operations might not function properly (error message is not output).
• Specify a value complying with the Java identifier naming rules provided in the Java language specifications. If the value does not comply with the Java identifier naming rules, a compilation error occurs during the execution of the cjwsimport command in the Web Service client development.
• For the wrapper style, the localName element of the javax.xml.ws.RequestWrapper annotation must be the same as the 'operation name'. If the element is not the same, an error message is output to the standard error output and logs (KDJW61047-E). However, if the javax.xml.ws.RequestWrapper annotation does not exist or if a blank character ("") is specified in the localName element of the javax.xml.ws.RequestWrapper annotation, a comparison is not done to check whether the names are the same and hence no message is output.

The action element is mapped to the action of the SOAP operation. In the action element, you can specify characters satisfying xsd:anyURI defined in RFC 2396, but the specified value is ignored at runtime.
