java - Error in WS client, NoClassDefFoundError: com.ibm.ws.wstx.handler.WSATGenerator

Question

I'm using the web client generation tool of IBM RAD Eclipse for web service. In all generated classes I have the following comment at the beginning.

//
// Generated By:JAX-WS RI IBM 2.1.1 in JDK 6 (JAXB RI IBM JAXB 2.1.3 in JDK 1.6)
//

I export the generated project to a JAR file and then add it to my EAR. When I call to WebService with the Client stub from my web application I get the following exception:

[26/09/13 14:17:15:737 CEST] 0000001f servlet       E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: Se ha creado una excepción no detectada en uno de los métodos de servicio del servlet action en la aplicación WATTEAR.

What is this WSATGenerator, and in which jar it should be available? Is it a standard library on WebSphere, or must it be manually configured?

Thanks

You are missing the IBM Websphere JAX-WS runtime in your client application. The class definition which fails to be found resides in the com.ibm.jaxws.thinclient_8.0.0.jar.
