Following steps helps in disabling schema validation in JAXB when SOAP response is received from SOAP web service call.

<entry key="set-jaxb-validation-event-handler" value="false"/>
e.g
<jaxws:client id="serviceSoa" serviceClass="com.koushik.enterprise.services.ServiceSoa"
address="url of service" username="username" password="password">
<jaxws:properties>
<entry key="set-jaxb-validation-event-handler" value="false"/>

</jaxws:client>
