    <p>I would change the approach rather than using an interceptor. If you need to invoke the exception strategy wihout triggering the until-succesful router first, I would move your cxf:jaxws-client etc. to a private flow. To quote Mule in Action 2nd edition on private flows: </p> <blockquote> <p>This decoupling allows defining processing and error handling strategies that are local to the private flow.</p> </blockquote> <pre><code>&lt;flow name="ProvaClient" doc:name="ProvaClient"&gt; ... &lt;until-successful objectStore-ref="OS_Bean" maxRetries="2" secondsBetweenRetries="2" doc:name="Until Successful" deadLetterQueue-ref="myQueue"&gt; &lt;processor-chain doc:name="Processor Chain: Wait For Web Service Response"&gt; &lt;processor-chain doc:name="Processor Chain: Web Service"&gt; &lt;flow-ref name="externalCallFlow" /&gt; &lt;/processor-chain&gt; &lt;logger message="PAYLOAD: #[payload]" level="INFO" doc:name="Logger" /&gt; &lt;/processor-chain&gt; &lt;/until-successful&gt; ... &lt;/flow&gt; &lt;flow name="externalCallFlow"&gt; &lt;cxf:jaxws-client operation="getCode" clientClass="it.aizoon.prova.client.ProvaService" port="ProvaPort" enableMuleSoapHeaders="true" doc:name="SOAP"&gt; &lt;/cxf:jaxws-client&gt; &lt;http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" path="service/prova" method="POST" doc:name="HTTP" /&gt; &lt;catch-exception-strategy doc:name="Catch Exception Strategy"&gt; &lt;!-- Handle exception here locally and return custom exception or error message for the unil-successful router --&gt; &lt;/catch-exception-strategy&gt; &lt;/flow&gt; </code></pre> <p>You can then handle exceptions locally and return a custom exception or error message for the until-successful router to catch using the following attribute: failureExpression="exception-type:java.lang.NumberFormatException"</p> <p>Here's a dummy example I knocked up to throw a NumberFormatException, log the exception in the exception strategy and retry:</p> <pre><code>&lt;flow name="test" doc:name="test"&gt; &lt;http:inbound-endpoint address="http://localhost:8081/test" doc:name="HTTP" /&gt; &lt;until-successful objectStore-ref="OS_Bean" maxRetries="2" secondsBetweenRetries="2" doc:name="Until Successful"&gt; &lt;processor-chain doc:name="Processor Chain: Wait For Web Service Response"&gt; &lt;processor-chain doc:name="Processor Chain: Web Service"&gt; &lt;flow-ref name="externalCallFlow" doc:name="Flow Reference" /&gt; &lt;/processor-chain&gt; &lt;/processor-chain&gt; &lt;/until-successful&gt; &lt;/flow&gt; &lt;flow name="externalCallFlow" doc:name="externalCallFlow"&gt; &lt;scripting:component&gt; &lt;scripting:script engine="groovy"&gt; throw new java.lang.NumberFormatException(); &lt;/scripting:script&gt; &lt;/scripting:component&gt; &lt;default-exception-strategy&gt; &lt;processor-chain&gt; &lt;logger level="ERROR" message="NumberFormatException Occurred : #[message.payload.getException().getCause()]" /&gt; &lt;scripting:component&gt; &lt;scripting:script engine="groovy"&gt; throw message.payload.getException().getCause(); &lt;/scripting:script&gt; &lt;/scripting:component&gt; &lt;/processor-chain&gt; &lt;/default-exception-strategy&gt; &lt;/flow&gt; </code></pre>

    1. COFirst of all thank you for the response. If the getCode() return an exception like NumberFormatException, how can I set as payload this exception name in the message in the exception strategy? My goal is to send a mail with the exception thrown. I don't want to get the SOAPFaultException, but the NumberFormatException

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
