camel Spring DSL onException doesn't fire at all - exception

Question

I am using the Camel DSL Spring route as reported below.
As you can see, I want to convert an xls file and if an exception occurs I need to log an error and move file in a specific folder.
It seems none of these steps happen, I just got an exception when converting the file and got a moveFailed of "file" component .
I suspect the exception mechanism does not transpose the handled flag and then the exception returns to caller , the file comp, and it proceeds with the moving.
How do I execute onException mechanism on exception
<route>
<from uri="file:C:/Users/Administrator/Desktop/HB_DATA/mov?delay=1000&move=../mov_done&moveFailed=../mov_fail"/>
<process ref="processor"/>
<to uri="bean:excelConverter"/>
<onException>
<exception >org.savino.hb.dataprovider.DataProviderException</exception>
<handled>
<constant>true</constant>
</handled>
<log loggingLevel="ERROR" message="HEY I GOT AN EXCEPTION" />
<to uri="file:C:/Users/Administrator/Desktop/HB_DATA/mov_fail?fileName={header.X_UID}"/>
<process ref="processorEx"/>
</onException>
<to uri="bean:finish"/>
</route>

Answer 1

The <onException> has to precede the code that is eager to run in error.
In your particular case, just move the exception handling immediately after the 'from', eg:
<route>
<from uri="..."/>
<!-- Exception handling -->
<onException>
<exception>org.savino.hb.dataprovider.DataProviderException</exception>
<handled>
<constant>true</constant>
</handled>
<log loggingLevel="ERROR" message="HEY I GOT AN EXCEPTION" />
<onException>
<!-- The route definition -->
<process ref="processor"/>
<to uri="bean:excelConverter"/>
<to uri="file:..."/>
<to uri="bean:finish"/>
</route>
A possible (more natural) alternative is a try-catch:
