org.xml.sax.SAXParseException: s4s-elt-invalid-content.1: The content of 'schema' is invalid. Element 'import' is invalid, misplaced, or occurs too often.

[Hervé BARRAULT <he...@gmail.com>]

Hi,

I'm using camel 2.4.0.fuse-00-00 (linked to cxf 2.2.9.fuse-01-00).


I have deployed 2 webservices using camel-cxf :

<cxf:cxfEndpoint id="notificationServiceEndpoint"
    address="http://0.0.0.0:8081/notification"
    serviceClass="com.example.cxf.NotificationPojoProvider">
    <cxf:properties>
      <entry key="schema-validation-enabled" value="true"/>
      <entry key="jaxb-validation-event-handler">
        <bean class="com.example.cxf.MyValidationHandler" />
      </entry>
    </cxf:properties>
  </cxf:cxfEndpoint>

<cxf:cxfEndpoint id="subscriptionServiceEndpoint"
    address="http://0.0.0.0:8081/subscription"
    serviceClass="com.example.cxf.SubscriptionPojoProvider">
    <cxf:properties>
      <entry key="schema-validation-enabled" value="true"/>
      <entry key="jaxb-validation-event-handler">
        <bean class="com.example.cxf.MyValidationHandler" />
      </entry>
    </cxf:properties>
  </cxf:cxfEndpoint>

These two services are defined in the same WSDL.

When using these two endpoints, I have systematically the following warning
due to an Exception (twice).
13:22:36,240 | WARN  | 2968410@qtp-20212684-13 | EndpointReferenceUtils |
SAXException for newSchema()

To be more precise : If I send my first message to Notification endpoint, I
have this exception only on Subscription Endpoint (for all messages) and
vice versa.
Does any have done a similar test before ?
How can I avoid this warning ?

Hervé

PS : Sorry i posted on both camel and cxf mailing list as I don't know if
it is more a cxf or a camel issue.
