Error description

  • JAXRS applications that specify a rest servlet such as
    com.ibm.websphere.jaxrs.server.IBMRestServlet in the web.xml
    must
    specify an application <init-param> will fail on application
    startup.  Currently the messaging is insufficient to allow the
    customer
    to determine that the <init-param> is missing.
    

Local fix

  • In our particular case the following worked:
    
    The reason for specifying the IBMRestServlet in the web.xml is
    to
    associate it with an Application subclass - in this case, the
    sample.ApplicationConfig class.  The JAX-RS implementation
    should be
    able to scan the WAR file and find appropriate Application
    subclases -
    so long as they are annotated with @ApplicationPath.  But if the
    user
    specifies the IBMRestServlet, then the JAXRS implementation in
    WAS will
    need to associate it with an application.  Without the
    init-param that
    indicates the application class, it won't know which application
    class
    is associated with which servlet (and more importantly, which
    servlet
    URI path).
    
    The customer should include the init-param element as such:
    <servlet>
      <servlet-name>JAX-RS Servlet</servlet-name>
    
    <servlet-class>com.ibm.websphere.jaxrs.server.IBMRestServlet</se
    rvlet-c
    lass>
      <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>sample.ApplicationConfig</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
    </servlet>
    
    We tested this addition to the web.xml and were able to start
    the server
    and web app without exception.

    *                      specifying a rest servlet in the        *
    *                      web.xml requires an application         *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When JAXRS applications specify a rest servlet, such as
    com.ibm.websphere.jaxrs.server.IBMRestServlet in the web.xml,
    then must also specify an application <init-param> or the
    application will fail to start.   Currently there is no
    messages to indicate clearly that this problems exists and
    explain what to do.
    

Problem conclusion

  • The following messages have been added to resolve this issue:
    CWWKW0101W (warn.servlet.specified.without.application)
    CWWKW0102W (warn.servlet.specified.with.invalid.application)
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 9.0.0.6.  Please refer to the Recommended Updates
