This subsection describes the precautions for using the addressing functionality.

• Fault message containing wsa:MessageAddressingHeaderRequired in the sub-code
  If the JAX-WS engine of the Web Service machine sends a fault message ^#1 containing wsa:MessageAddressingHeaderRequired in the sub-code, set up the same value (wsa:MessageAddressingHeaderRequired) as the sub-code in the sub-sub code of the fault message.
  
• Fault message containing wsa:ActionNotSupported in the sub-code
  If the Web Service-side JAX-WS engine sends a fault message ^#2 containing wsa:ActionNotSupported in the sub-code, no value is set up in the sub-sub code of the fault message.
  

#1

Fault message without a required element in the addressing header

#2

Fault message in which the value of the wsa:Action element of the addressing header differs from the wsa:Action value in the Web Service
