Problem debugging Exception
Hello,
I have the attached project.
The problem is I get an exception. I cannot catch this exception in the
Eclipse debugger to see what is wrong.
When I comment out the line: .setHeader("id",
xpath("/Product/id/text()")).log("id = ${in.header.id}")
it works.
When I leave it in it does not work I get the exception:
[el-1) thread #4 - ShutdownTask] DefaultShutdownStrategy INFO
Waiting as there are still 3 inflight and pending exchanges to complete,
timeout in 298 seconds.
[mel-1) thread #0 - file://data] DefaultErrorHandler ERROR Failed

ID-ID02405-65164-1367748163096-0-2). Exhausted after delivery attempt: 1

org.apache.camel.impl.DefaultExchange.setException(DefaultExchange.java:272)[camel-core-2.11.0.jar:2.11.0]
I looked at the line of the incoming file to see if I see something weird
but I cannot find anything.
I also cannot 'debug' my code to see where it goes wrong.
My question is to any Camel expert:
1. What is wrong here?
2. How can I easily debug a Camel project. Do I need to add additional
logging.
3. I saw something like Fuse that can debug/trace stuff. This is not
opensource anymore, is there an alternative to debug in Fuse terms instead
of low level Java.

Izaak

Hi
Here is some pointers how to debug Camel routes
http://camel.apache.org/debugger.html
But in your case there must be more information in that stacktrace
that can tell you what the problem is.
As you use XML and XPath its 99% a problem with your xpath expression
not working. There is XML / XPath tooling you can use to try and test
your expressions to make sure its valid.
And mind that if your XML uses namespaces, then the xpath expression
must use that as well.
This is a common issue with the xpath api in Java and you can google
about this to find out how to do it.
As well we got some pointers here: http://camel.apache.org/xpath
