Chapter 23. Web Services

Seam integrates with JBossWS (JWS) to allow standard Java EE web services to take full advantage of Seam's contextual framework, including conversational web service support. This chapter guides you through web service configuration for a Seam environment.

For Seam to create contexts for web service requests, it must first have access to those requests. org.jboss.seam.webservice.SOAPRequestHandler is a SOAPHandler implementation that manages the Seam component lifecycle during the scope of a web service request.

standard-jaxws-endpoint-config.xml (a configuration file) should be placed in the META-INF directory of the JAR file that contains the web service classes. This file contains the following SOAP handler configuration:

<jaxws-config xmlns="urn:jboss:jaxws-config:2.0" 
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
              xmlns:javaee="http://java.sun.com/xml/ns/javaee"
              xsi:schemaLocation=
                "urn:jboss:jaxws-config:2.0 jaxws-config_2_0.xsd">
                
  <endpoint-config>
    <config-name>Seam WebService Endpoint</config-name>
    
    <pre-handler-chains>

        <javaee:handler>

            SOAP Request Handler
          </javaee:handler-name>

      </javaee:handler-chain>
      
    </pre-handler-chains>
    
  </endpoint-config>
  
</jaxws-config>
