Question

We are trying to implement a JAXB2Marshaller to our webservice project, but we get a java.lang.NoClassDefFoundError on the class javax.activation.DataHandler, however the dependency to activation artifact exists and we have verified that the activation.jar is in fact being deployed, so this caused by something else.

Here is the app config:

<sws:annotation-driven />

    <sws:dynamic-wsdl id="security" portTypeName="security" locationUri="/">                               
        <sws:xsd location="classpath:security-service.xsd"/>                                                  
    </sws:dynamic-wsdl>

    <bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter">
        <constructor-arg ref="marshaller" />
    </bean>

    <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="classesToBeBound" >
            <list>
                <value>com.app.model.SimpleRoleList</value>
            </list>
        </property>
        <property name="schema" value="classpath:types.xsd"/>
    </bean>

As always, help is really appreciated.

EDIT————–

This only happens when the app is deployed to Tomcat 6.

Answer 1

I just noticed I had older versions jaxb-api.jar and jaxb-impl.jar on the Tomcat’s endorsed folder than the ones I’m using on the app.
There are two ways of solving this; First one is to remove the jars from the endorsed folder and then add jaxb as a runtime dependency on the projects POM:

<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.2.2</version>
</dependency>

The second one is just to update the jars on the endorsed folder to newer versions (In my case its version 2.2.2).

That fixes it.

Hope its helpful to someone.
