Hello Claus,
sorry to bother, but i am still losing the plot with Exception Handling :(
i read Camel In action chapter, and this is what i came out with:
<camel:route>
<camel:from uri="seda:processBloombergShares" />
<camel:onException>
<camel:exception>java.lang.Exception</camel:exception>
<camel:handled>
<camel:constant>true</camel:constant>
</camel:handled>
<camel:to
uri="bean:exceptionHandler?method=handleException" />
</camel:onException>
<camel:process ref="bloombergProcessor" />
<camel:bean ref="bloombergServiceActivator" method="fetchData"
/>
<camel:to uri="bean:endpointBean?method=handleBloombergShare" />
</camel:route>
the BloombergProcessor is throwing an Exception , as in code b elow
public void process(Exchange exchange) throws Exception {
// TODO Auto-generated method stub
Set<String> set = new HashSet<String>();
set.add("BLOOMBERG-WMT");
//set.add("BLOOMBERG-GE");
String portfolio = (String)exchange.getIn().getBody();
throw new Exception("Exception from Bloomberg PRocessor...");
}
this is the signature of my exception handler handleException method
public void handleException(Map<?, ?> in, String payload, Map<String,
Object> out) {
LOGGER.info("-------Handling exceptions:");
//exceptions.add(exception);
}
But somehow that method is never called...
am i using the right signature?
what am i forgetting?
w/kindest regards
marco
