One of my client put the file request under directory placeorder with below configuration in CAMEL
<route id="FileToJMS">
<from uri="file:target/placeorder" />
<to uri="jms:incomingOrders" />
</route>
Once processing is done from incomingOrders, i want to send the some response to customer who initiated file request. How can i achieve it with CAMEL (probably using request reply or return address pattern). Any ideas?
Like so:
<route id="FileToJMS">
<from uri="file:target/placeorder" />
<to uri="jms:incomingOrders" />
<to uri="mock:response"/>
</route>
replace "mock:response" with whatever component you want to send the response with

I have a Camel route that looks something like the one below. If all records parse successfully, then I get an email from the onCompletion step. If one record gets an exception then the rest of the records will process, which is fine, but the onCompletion step does not fire.
What I'd like is for the onCompletion step to run even if there are errors and to be able to send a message saying "route completed with errors". How can I do this?
<route id="route1">
<from uri="file://C:/TEMP/load?noop=true&idempotentRepository=#sysoutStore&sorter=#externalDataFilesSorter"/>
<choice>
<when>
<simple>${file:name} regex '*file.*.(txt)'</simple>
<to uri="direct:RouteFile" />
</when>
</choice>
</route>
<route id="testRouteDirect">
<from uri="direct:RouteFile" />
<onException>
<exception>java.lang.IllegalArgumentException</exception>
<redeliveryPolicy maximumRedeliveries="1" />
<handled>
<constant>true</constant>
</handled>
<to uri="log:java.lang.IllegalArgumentException"></to>
</onException>
<onException>
<exception>java.text.ParseException</exception>
<redeliveryPolicy maximumRedeliveries="1" />
<handled>
<constant>true</constant>
</handled>
<to uri="log:java.text.ParseException"></to>
</onException>
<split parallelProcessing="false" strategyRef="exchangePropertiesAggregatorStrategy" >
<tokenize token="\r\n"/>
<to uri="log:Record"></to>
</split>
<onCompletion>
<to uri="log:completion"></to>
<to uri="smtp://mail.com?contentType=text/html&to=done#test.com&from=route#test.com&subject=we're done" />
</onCompletion>
</route>
The best part of your route is, you have onException inside your route with handled=true. So move your onCompletion to the parent route(route1), It should work !
There are a bunch of tickets related to oncompletion on the camel site: Camel Jira URL. I upgraded to a newer version of camel & I don't get this issue any more.
Help needed on setting headers based on the method call from bean integration.
within my application I am using a custom POJO and there are before I actually send the message over the wire I want to do set the headers on the exchange, but don't want to do it within my bean and rather do it where my spring DSL is written for the route.
I know that usually the value returned from method is sent as body for the message to the next the endpoint but i want to send values returned as header.
I have attached a sample of my route needs to be, and want:
<route id="someRoute">
<from ref="InboundAsyncEndpoint" />
<to uri="bean:validatorBean?method=validateMessageInternals(MyCostomMessagePojo obj)" />
<choice>
<when>
<simple>
${body.getMetaData().getFinalDestinationName()} == 'AMQEndpoint'
</simple>
<to uri="bean:payloadAndHeaderExtractor?extractHeader(MyCostomMessagePojo obj)" />
<to uri="bean:payloadAndHeaderExtractor?extractPayload(MyCostomMessagePojo obj)" /> <!-- i want the headers being set on the exchange from the map that is returnd from the previous bean and method -->
<to uri="activemq:someQueue"
</when>
<otherwise>
...
...
</otherwise>
</choice>
You can do that in the following way:
<setHeader headerName="YOUR_HEADER">
<simple>bean:payloadAndHeaderExtractor?extractHeader(MyCostomMessagePojo obj)</simple>
</setHeader>
Hope this helps.

I am able to called Web Service, now what ever response came from web service, i need to fetch same response in java code so that i am able to further processing.
<camelContext xmlns="http://camel.apache.org/schema/spring" trace="false">
<route id="my_Sample_Camel_Route_with_CXF">
<from uri="file:src/data?noop=true"/>
<log loggingLevel="INFO" message=">>> ${body}"/>
<to uri="cxf://http://www.webservicex.net/stockquote.asmx?wsdlURL=src/main/resources/META-INF/stockquote.wsdl&serviceName={http://www.webserviceX.NET/}StockQuote&portName={http://www.webserviceX.NET/}StockQuoteSoap&dataFormat=MESSAGE"/>
<log loggingLevel="INFO" message=">>> ${body}"/>
</route>
Instead of logging using
I have a simple route in camel, which reads messages from an activemq queue 'A' and writes it to another activemq queue 'B'.I was able to get this to this part to work.
But I need to add a new property to the message before writing it to 'B'. I have tried to add the property 'prop1' to the message using the Spring DSL below, but the property is not being added to the message.
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="activemq:queue:A"/>
<setProperty propertyName="prop1">
<simple>prop1Value</simple>
</setProperty>
<to uri="activemq:queue:B"/>
</route>
</camelContext>
Is this the correct way to add a property to a message in SPRING DSL?
Use a header instead of a property:
<route>
<from uri="activemq:queue:A"/>
<setHeader headerName="prop1">
<constant>prop1Value</constant>
</setHeader>
<to uri="activemq:queue:B"/>
</route>
<route>
<from uri="activemq:queue:B" />
<log message="prop1 = ${header.prop1}" />
</route>
Camel headers are transferred to JMS properties which are transferred back to Camel headers as can be seen looking at the implementation of org.apache.camel.component.jms.JMSBinding. The Camel properties are skipped.
I want to do File Poller of CSV, then unmarshaling.like this:
<route>
<from uri="file:///some/path/to/pickup/csvfiles?delete=true&consumer.delay=10000" />
<unmarshal>
<csv />
</unmarshal>
<to uri="bean:myCsvHandler?method=doHandleCsvData" />
</route>
But I also want to get also the file name in my bean.
How do I do this ?
Have doHandleCsvData bind using the Exchange doHandleCsvData(Exchange exchange) then you can get the file name from the headers, extract the body and process the data.
