Trazas en el log de webservices

El siguiente código te permitirá imprimir en el log las trazas de entrada y salida de un servicio web:

Si usas JDK 7 en adelante:

 static {
        System.setProperty("com.sun.xml.ws.transport.http.client.HttpTransportPipe.dump", "true");
        System.setProperty("com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump", "true");
        System.setProperty("com.sun.xml.ws.transport.http.HttpAdapter.dump", "true");
        System.setProperty("com.sun.xml.internal.ws.transport.http.HttpAdapter.dump", "true");
    }

Como agregar un wsee-security y basic-authentication aun webservice con JAX-WS

Después de investigar un problema relacionado con la duplicidad de encabezados en los Handlers al intentar manipular el mensaje SOAP que enviamos mediante un WebService utilizando la libreria JAX-WS, he encontrado al fin una solución que les aliviará los dolores de cabeza con estos errores. 

Seguramente te habrás encontrado la duplicidad de targetnamepsace:

• S="http://schemas.xmlsoap.org/soap/envelope/" 
• SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/". 

El posible origen del problema es que estas usando JAX-WS para generar el servicio web (bajo JAX-B) y posteriormente usas SoapHandler (bajo SAAJ) para manipular el mensaje SOAP.

¿Cómo lo sé? La respuesta es que el targetnamepsace S lo genera JAXB y el targetnamepsace SOAP-ENV lo genera SAAJ.

Al usar el SOAPHandler posiblemente estés obteniendo el mensaje de esta forma:

SOAPMessage msg = SOAPMessageContext.getMessage();

Al obtener el mensaje usando  SOAPMessageContext.getMessage() automaticamente SAAJ intenta crear una cabecera por lo que agrega un header vacío. y en su defecto declara el nuevo targetnamespace SOAP-ENV.

Para resolver el problema, diseñe una clase Helper que te facilitará el trabajo de agregar en JAX-WS la cabecera sin manipular el mensaje. Además verás otras utilidades interesantes que se pueden incluir en el helper.
