i'm using camel to validate an xml and in the route I'm doing the following:
<route>
<from uri="file:{{file.inbox}}?preMove=inprogress&move=../.done"/>
<doTry>
<to uri="validator:classpath:idocOrderStatus.xsd"/>
<to uri="file:{{file.outbox.valid}}"/>
<doCatch>
<exception>org.apache.camel.ValidationException</exception>
<to uri="file:{{file.outbox.invalid}}"/>
</doCatch>
</doTry>
</route>
and I'm getting the following error:

I do not understend why I'm getting this error? There is anyway to import this class in the camel context? How should I do it?

Any idea on this?
This will work camel 2.x operation but if you try to upgrade camel 3.x for existing code. So, in that case you need to change this code to like below sample . but rather than myBean provide whole class package path.
Try below sample code..
for more details, please check below official website..
https://camel.apache.org/components/3.17.x/languages/bean-language.html
I have the following route definitions file (linehaul-routes.xml):
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://camel.apache.org/schema/spring"
xsi:schemaLocation="
http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd">
<route id="route1" errorHandlerRef="myErrorHandler">
<from uri="amqp:queue:DSMLH_consignment_event"/> <!-- AMQP queue to which I send messages to trigger the route !-->
<to uri="https://pesho.free.beeceptor.com/"/> <!-- Returns http 500 !-->
</route>
</routes>
I also have a file with error handler in the same directory (linehaul-error-handlers.xml):
<errorHandlers>
<errorHandler id="myErrorHandler" type="DefaultErrorHandler">
<redeliveryPolicy maximumRedeliveries="5" redeliveryDelay="2000"/>
</errorHandler>
</errorHandlers>
And application.properties
camel.context.name=testContext
camel.main.routes-include-pattern=classpath:routes/linehaul-routes.xml,classpath:routes/linehaul-error-handlers.xml
When I run the code I get the following stacktrace

What is wrong with the route to error handler mapping ?
(My goal is to make my route to re-try several times on http 500)
Camel Quarkus only supports 'simple' XML routes. You cannot define beans directly like you can with Camel Spring XML.
Instead, you can declare a CDI bean and reference it in the XML. For example.
#Named("myErrorHandler")
public DefaultErrorHandlerBuilder createDefaultErrorHandler() {
return new DefaultErrorHandlerBuilder()
.maximumRedeliveries(5)
.redeliveryDelay(2000);
}
Then you can reference the bean via errorHandlerRef on the route tag.
<route id="route1" errorHandlerRef="myErrorHandler">
I'm using apache camel http4 for http server.
JBoss Fuse Karaf container 6.3.0.redhat-310
has bundled camel-core 2.17 - (2.17.0.redhat-630310)
I'm trying to use exception class
org.apache.camel.component.http.HttpOperationFailedException
to catch HTTP response exceptions.
However, the associated routes fail to start due to
Caused by: java.lang.ClassNotFoundException: org.apache.camel.component.http.HttpOperationFailedException
I've added as dependency camel-http, with no change, still fails.
It doesn't seem that this class is included anymore?
Q. Is the Caused by: java.lang.ClassNotFoundException: org.apache.camel.component.http.HttpOperationFailedException available to http4 servers, or does anyone know what I'm doing wrong.

Caused by: java.lang.ClassNotFoundException: org.apache.camel.component.http.HttpOperationFailedException
I've also tried using the Global exception handler using
<exception>org.apache.camel.component.http.HttpOperationFailedException</exception>
<continued>true</continued>
</onException>
but, here I get an ERROR exception saying Continued cannot have children????
thank you!
I was facing the same issue, the correct class is
org.apache.camel.http.common.HttpOperationFailedException
it should there inside the http4 component
I just used the simple language to achieve what I needed. I simply need to continue the route after an http error code not OK or 200. this approach works, but I would love to understand how to accomplish this with my original question.
can this be done with camel's http4 component, it appears these classes are not part of it anymore?
also, if someone can, what is wrong with my onException clause?
thanks!
this is what I did
<to id="http4-1" uri="http4://d1e53858-2903-4c21-86c0-95edc7a5cef2.predix-uaa.run.aws-usw02-pr.ice.predix.io:443/oauth/token?throwExceptionOnFailure=false"/>

After upgrading from Camel 2.1 to 2.17 and some code modification we are having some problems with the exception handling in Camel. We send message from app A to app B. The happy flow works fine, but the unhappy flow doesn't.
We send the message to cause an exception but it is not correctly handled in the onexception block.
Actually, we see the following tracelog: ProcessTaskEx - message received, but I don't see: ProcessTaskEx - exception
The exception we get from Camel is:
camel exchange failed without an exception: <SOAP-ENV:Fault xmlns:SOAP-ENV>
Our route looks like this, any idea what the problem could be? Thank you very much for your time community! :)
<?xml version="1.0" encoding="ASCII"?>
<routes xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="switchyard://ProcessTaskEx"/>
<log message="ProcessTaskEx - message received: ${body}" loggingLevel="DEBUG" logName="WebServiceQueues" />
<to uri="switchyard://RequestCapacity"/>

<exception>java.lang.Exception</exception>
<exception>webservicequeues.utilities.WebServiceQueueException</exception>

</route>
</routes>
As fas as I remember, faults are not handled by default. In order to enable this a property must be set: handleFault="true". It can be set for the whole Camel context or for individual routes.
Example for a route in XML:
<route handleFault="true">
...
</route
I have the onException block below that worked before I upgraded to from camel 2.14 to camel 2.16.1. Before the update, I would get my error caught and printed in the log - "Error posting to MR". After I upgraded to camel 2.16.1, I still get my error in the log, but now, always, my handled error is followed by another timestamp with what appears to be camel default error handler for the error I think I already handled. It looks like this:
"2016-01-26 15:07:09,571 [Camel (mrPostContext) thread #56 - JmsConsumer[mrPost]] ERROR org.apache.camel.processor.DefaultErrorHandler - Failed delivery for (MessageId"....
I don't know if I'm doing something wrong, I tried using java.lang.Throwable instead of java.lang.Exception but so far had no luck. Haven't found anything helpful in documentation yet. As I'm far from being good with camel, I will much appreciate some help.
<route id="mrPost">
<from uri="activemq:mrPost?concurrentConsumers=8" />
<onException>
<exception>java.lang.Exception</exception>
<redeliveryPolicy maximumRedeliveries="2" redeliveryDelay="1000"/>
<handled>
<constant>true</constant>
</handled>
<to uri="activemq:mr-post-fail" />
<log loggingLevel="ERROR" message="Error posting to MR body:${out.body} exception message: ${exception.message} body:${exception.responseBody}" />
</onException>
<setHeader headerName="CamelHttpMethod">
<constant>PUT</constant>
</setHeader>
<recipientList>
<simple>{{mr.source}}/${headers.id}</simple>
</recipientList>
</route>
Here is a much cleaner solution in case someone is looking for it:
<errorHandler id="loggingErrorHandler" type="LoggingErrorHandler" logName="LoggingErrorHandler" level="OFF"/>
<camelContext id="mrPostContext" trace="false" errorHandlerRef="loggingErrorHandler" >
I think that camel is failing where it puts the message on to the error queue mr-post-fail and is throwing an exception when doing so, hence your exception is propogating to the DefaultExceptionHandler. Since the logging is after the put queue call it is not working as you expected.
If not the case can you give the whole line of the error thats being printed.
"2016-01-26 15:07:09,571 [Camel (mrPostContext) thread #56 - JmsConsumer[mrPost]] ERROR org.apache.camel.processor.DefaultErrorHandler - Failed delivery for (MessageId"..
I got the defaultErrorHandler to collapse with these 2 adjustments:
- set messageHistory="false" on CONTEXT
- set logStackTrace="false" for onException block, like this:
<redeliveryPolicy maximumRedeliveries="2" redeliveryDelay="1000" logStackTrace="false" />
The timestamp with default error handler still shows up, but much easier on the eye, it looks like this:
2016-02-01 11:26:27,792 [Camel (mrPostContext) thread #262 - JmsConsumer[mrPost]] ERROR org.apache.camel.processor.DefaultErrorHandler - Failed delivery for (MessageId: ID-qn7nwscms01-com-44939-1454025367155-1569-4 on ExchangeId: ID-qn7nwscms01-com-44939-1454025367155-1569-5). Exhausted after delivery attempt: 3 caught: org.apache.camel.http.common.HttpOperationFailedException: HTTP operation failed invoking http://mr.cloud.dig.com/api/contents/news/30939510 with statusCode: 409. Processed by failure processor: FatalFallbackErrorHandler[Pipeline[[Channel[SetHeader(CamelExceptionCaught, Simple: Headers: ${headers} Message: ${exception.message} Body: ${exception.responseBody})], Channel[sendTo(Endpoint[activemq://mr-post-fail])], Channel[choice{when Filter[if: Simple: ${exception.message} not contains "statusCode: 409" do: Pipeline[[Channel[SetHeader(Content-Type, text/plain)], Channel[SetHeader(to, Simple: lw#ac.com)], Channel[SetHeader(subject, Simple: Error posting to MR)], Channel[SetBody(Simple: ${header.CamelExceptionCaught})]]]]}], Channel[Log(mrPost)[Error posting to MR ID: ${headers.contentId}, type:${headers.cmsContentType}, modified:${headers.lastModifiedDate}, getTime:${headers.lastModifiedGetTime}]], Channel[Log(merlinPost)[Error posting to MR body:${out.body} exception message: ${exception.message} body:${exception.responseBody}]]]]]
I hope there is a way to turn it off completely.
I also tried using defaultErrorHandler setup:
<errorHandler id="defaultErrorHandler" type="DefaultErrorHandler">
<redeliveryPolicy logStackTrace="false"/>
</errorHandler>
but it makes no impact.
You can use like the example in this page: http://camel.apache.org/exception-clause.html
<!-- setup our error handler as the deal letter channel -->
<bean id="errorHandler" class="org.apache.camel.builder.DeadLetterChannelBuilder">
<property name="deadLetterUri" value="activemq:mr-post-fail"/>
</bean>
<!-- this is the camel context where we define the routes -->
<!-- define our error handler as a global error handler -->
<camelContext errorHandlerRef="errorHandler" xmlns="http://camel.apache.org/schema/spring">
<route>
<!-- the route -->
<from uri="activemq:mrPost?concurrentConsumers=8" />
<setHeader headerName="CamelHttpMethod">
<constant>PUT</constant>
</setHeader>
<recipientList>
<simple>{{mr.source}}/${headers.id}</simple>
</recipientList>
</route>
</camelContext>
Or, set in rote, to the error handle work only with an specific route
<route errorHandlerRef="errorHandler">
...
</route>
And remove from camelContext
