FUSE-ESB 4.4.1: can't create specific fault for cxf web service

[dako_t]

Hi all,

I can't create a specific fault message for a cxf web service. The web service works fine but if an error occurs I get always

a common soap error. I've tested it with soapUI and got the following response after an Exception within my camel route:

  <soap:Fault>

    <faultcode>soap:Server</faultcode>

    <faultstring>Fault occurred while processing.</faultstring>

  </soap:Fault>

  This is my route which starts with an cxf web service invocation in OSGI module A.

        <camelContext xmlns="http://camel.apache.org/schema/spring">

                <route id="getPositions4ShipsEndpointRoute">

                        <from uri="cxf:bean:getPositions4ShipsEndpoint"/>

                        <bean ref="consumerLayerService" method="fillExchangeWithMinDateOfData"/>

                        <to uri="activemq:queue:getPositions4Ships"/>

                </route>

        </camelContext>

        In OSGI module B I have a route and an exception handler. within the method "getPositions4Ships" I create a StringIndexOutOfBoundsException.

        <camelContext xmlns="http://camel.apache.org/schema/spring">

                <propertyPlaceholder id="properties" location="ref:props"/>

                <onException>

                        <exception>java.lang.Exception</exception>

                        <handled><constant>true</constant></handled>

                        <transform>

                                <simple>$</simple>

                        </transform>

                        <to uri="activemq:queue:exceptionHandlerQueue"/>

                </onException>

                <route id="getPositions4ShipsDataRoute">

                        <from uri="activemq:queue:getPositions4Ships" />

                        <bean ref="aisDataService" method="getPositions4Ships"/>

                </route>

        </camelContext>

        After the exception is thrown the route ends within the "errorService".

  <camelContext xmlns="http://camel.apache.org/schema/spring">

                <route id="exceptionHandlerRoute">

                        <from uri="activemq:queue:exceptionHandlerQueue" />

                        <bean ref="errorService" method="returnErrorMessage"/>

                </route>

        </camelContext>

        This is the code of the method "returnErrorMessage".

  The expected StringIndexOutOfBoundsException was logged but the web service returns always the fault string listed above "Fault occurred while processing.".

        public void returnErrorMessage(Exchange exchange) {

                Throwable cause = exchange.getIn().getBody(Exception.class);

                String errorMessage = cause.getMessage();

                log.error("returnErrorMessage, exception:", exchange.getIn().getBody());

                SoapFault fault = new SoapFault(errorMessage, new QName("ff", "dd"));

                fault.setMessage(errorMessage);

                exchange.getOut().setFault(true);

                exchange.getOut().setBody(fault);

        }

        What should I change to return a specific error?

        After invoking the method "returnErrorMessage" I have the following warning within my ServiceMix log:

        13:11:55,995 | WARN  | qtp4895594-292   | PhaseInterceptorChain | 141 - org.apache.cxf.bundle - 2.4.6 | Interceptor for GetAisPositions4DVElbeEndpointService#getPositions4Ships has thrown exception, unwinding now

Hi,

I didn't found any route which has the camel-cxf endpoint.

I'm not sure how you route the response back.

Here is an unit[1] in the camel-cxf that you can take a look.

Hi Willem,

this is my cxf-Endpoint configuration.

><cxf:cxfEndpoint id="getAisPositions4ShipsEndpoint" address="http://0.0.0.0:8383>/cxf/GetAisPositions4Ships/"

  >serviceClass="de.mycompany.dataserver.consumer.webservice.GetPositions4ShipsEndpo>int">

<cxf:inInterceptors>

   <ref bean="securityInInterceptor" />

</cxf:inInterceptors>

<cxf:properties>

   <entry key="publishedEndpointUrl" value="${ships.publishedEndpointUrl}" />

</cxf:properties>

</cxf:cxfEndpoint>

I've tried some code of your example but I got the same result. I've set the following within my ErrorService:

SoapFault fault = exchange.getProperty(Exchange.EXCEPTION_CAUGHT, SoapFault.class);

exchange.getOut().setFault(true); exchange.getOut().setBody(fault);

Where should I set the following code snippet within my route?

from(routerEndpointURI).setFaultBody(constant(SOAP_FAULT));

Best regards

Hi,

Could you please add your xml into tag

...

, so that we can get a better view.

Hi Freeman,

I have added quote tags, now the code should be better readable.

Best regards

hi,

any answer to this issue after all ?

[dako_t]

Unfortunately no, currently I can live without specific error responses.
