Local fix

• Problem can be workarounded by adding the following JVM
  argument to the process which is generating the wsdl:
  
   -Dcom.ib
  m.websphere.webservices.WSDL_Generation_Extra_ClassPath=<WAS_Ins
  tall_Dir>/plugins/javax.j2ee.validation.jar

  ****************************************************************
  When deploying a JAX-WS web service application without a WSDL
  packaged, if the application uses a Java validation API in its
  web service implementation, the following error will be
  reported:
  WSWS7027E: JAX-WS Service Descriptions could not be correctly
  built because of the following error:
  javax.xml.ws.WebServiceException: WSWS7054E: The Web Services
  Description Language (WSDL) file could not be generated for
  the example.sampleService Web service implementation class
  because of the following error:
  java.lang.NoClassDefFoundError:
  javax.validation.ConstraintViolation
  

Problem conclusion

• When deploying a JAX-WS web service application which uses the
  Java Validation API, the JAX-WS runtime failed to generate the
  WSDL file because there was no Java Validation library in the
  classpath.
  
  The JAX-WS runtime is changed to include the necessary Java
  Validation library in the classpath while generating a WSDL
  file for the web service application.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.18 and 9.0.5.5. For more information, see 'Recommended
  Updates for WebSphere Application Server':
