where to keep wsdl file when using webservices with EJB ?

[RaviNada Kiran]

Hi ,

I exposed Stateless SessionBean EJB as webservice , i have generated wsdl file using java2wsdl , now where should i keep this wsdl file ???

Usually your container/application server takes care of that.

In a J2EE 1.4 container the relationship between the WSDL and the session bean is captured in webservices.xml

<!-- RMH Listing 23-5 webservices.xml File for BookQuote SLSB -->
<webservices
    xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:mh="http://www.Monson-Haefel.org/jwsbook/BookQuote/BookQuote"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://www.ibm.com/webservices/xsd/j2ee_web_services_1_1.xsd"
    version="1.1">
  <webservice-description>
    <webservice-description-name>BookQuote</webservice-description-name>
    <!-- location of the file describing the web service -->
    <wsdl-file>/META-INF/wsdl/bookquote.wsdl</wsdl-file>
    <jaxrpc-mapping-file>/META-INF/bookquote.map</jaxrpc-mapping-file>
    <port-component>
      <!-- unique (within webservices.xml) component identifier 
           used by deployment tools and  the jax-rpc mapping file -->
      <port-component-name>BookQuoteBean</port-component-name>
      <wsdl-port>mh:BookQuotePort</wsdl-port>
      <service-endpoint-interface>com.jwsbook.jaxrpc.BookQuote</service-endpoint-interface>
      <service-impl-bean>
        <!-- Refer to the "ejb-name" as defined in the "session" element of the ejb-jar.xml -->
        <ejb-link>BookQuoteSLSB</ejb-link>
      </service-impl-bean>
    </port-component>
  </webservice-description>
</webservices>

<!-- RMH Listing 23-6 ejb-jar.xml File for the BookQuoteSLSB -->
<ejb-jar ...>
  <enterprise-beans>
    <session>
       <!-- This name is used in the webservices.xml ejb-link -->
       <ejb-name>BookQuoteSLSB</ejb-name>
       <ejb-class>com.jwsbook.jaxrpc.BookQuoteBean</ejb-class>
       <session-type>Stateless</session-type>
       ...
    </session>
  </enterprise-beans>
  ...
</ejb-jar>

Thanks Peer for your time . My question may be foolish , but i still wanted to know that i am using Apache axis to expose stateless SB EJB as web service , still we need web services.XML file ???

Apache Axis 1.x (or Axis2 for that matter) doesn't support EJB - so you are going to need a separate EJB container

Apache Axis 1.x never followed the J2EE 1.4 deployment standard for web services - it doesn't use a webservices.xml at all. It uses the server-config.wsdd (Deployment WSDD reference) instead.

Apache Axis 1.x generates its own WSDL dependent the WSDD settings.

Ultimately what goes where is dependent on the integration between Axis 1.x and the EJB container that you are using.
