Hi,

    I get this exception when trying to deploy a Session Bean as Web Service:

JBoss is looking for a servlet link when the deployed webservice uses an ejb link, this are the xml descriptors:

configuration.xml:


<java-wsdl>

<namespaces target-namespace="http://servicios.com/"
type-namespace="http://servicios.com/types"/>

<webservices ejb-link="HelloBean"/>
</java-wsdl>


ejb-jar.xml:

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns="http://java.sun.com/xml/ns/j2ee" version="2.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">
<display-name>chapter 12 EJB JAR</display-name>
<enterprise-beans>

<ejb-name>HelloBean</ejb-name>
<service-endpoint>com.servicios.Hello</service-endpoint>
<ejb-class>com.servicios.HelloBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>

</enterprise-beans>
<assembly-descriptor>
<method-permission>


<ejb-name>HelloBean</ejb-name>
<method-name>*</method-name>

</method-permission>
<container-transaction>

<ejb-name>HelloBean</ejb-name>
<method-name>*</method-name>

<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>
</ejb-jar>


And this are the generated webservices.xml:

The ejb gets correctly deployed as I can see in JBoss console and jmx console. As you can see, the webservices.xml definition file defines an ejb link:

   <service-impl-bean>
    <ejb-link>HelloBean</ejb-link>
   </service-impl-bean>

Why does Jboss tries to look for a servlet link with this configuration...

I'm using Jboss 4.0.5 GA
