I only have to consume mails from the mailbox which are from address x OR address y. How can i configure this in a camel uri?
I've only found the searchTerm configuration with 1 address(searchTerm.from=x)
Segment your route using Direct Component, it works like method call.
For example:
<route>
<from uri="imap://admin#mymailserver_1"/>
<to uri="direct:processMail"/>
</route>
<route>
<from uri="imap://admin#mymailserver_2"/>
<to uri="direct:processMail"/>
</route>
<route>
<from uri="direct:processMail"/>
<to uri="bean:MailService?method=process"/>
<to uri="activemq:queue:mail.out"/>
</route>

<multicast>

I am trying to set headers inside the multicast tag. Headers need to be sent to an audit bean named as an audit. below is my route. Can anyone help me on this.
The Multicast EIP allows to route the same message to a number of endpoints and process them in a different way. its is important keyword is SAME.default multicast sync okey but camel dont send changed to to next node. u must call set header before multicast eip
i created a route that is supposed to read from an OPC-UA endpoint. The read operation should be performed every second, based on a timer. Every example i found shows that the route can only have one from item. My route looks like this:
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route id="opctorest">
<from uri="timer://simpleTimer?period=1000"/>
<log message="Triggered Route: opctorest: Sensorreading body: ${body}"/>
<to uri="milo-client:tcp://0.0.0.0:4840/freeopcua/server?nodeId=2&namespaceUri=http://examples.freeopcua.github.io"/>
<convertBodyTo type="java.lang.String"/>
<to uri="stream:out"/>
</route>
</camelContext>
When i deploy the route, it gets called every second, but it writes to the endpoint, since the call is declared in a to element. How can i turn this into a read? I could not find a solution so far. Thanks!
Use the .enrich() to turn it into a read when you want to read in the middle of a route.

For your example something similar to (not tested):
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route id="opctorest">
<from uri="timer://simpleTimer?period=1000"/>
<log message="Triggered Route: opctorest: Sensorreading body: ${body}"/>
<enrich uri="milo-client:tcp://0.0.0.0:4840/freeopcua/server?nodeId=2&namespaceUri=http://examples.freeopcua.github.io"/>
<convertBodyTo type="java.lang.String"/>
<to uri="stream:out"/>
</route>
</camelContext>
I have a route where I'd like to compute if "from" is activemq or something else. I found replaceFromWith, but it seems to be used for testing only. I tried using camel's choice when/otherwise to switch between "from activemq" and "from seda", but that errors out as invalid syntax. I'm looking for something that would do the following:
<route id="doPost">
<choice>
<when>
<groovy>exchange.getIn().getHeader("sometest") != null</groovy>
<from uri="activemq:doPost?..."/>
</when>
<otherwise>
<from uri="seda:doPost?....."/>
</otherwise>
</choice>
Thanks in advance, appreciate the help.
You cannot dynamically select a consumer based on the exchange, the exchange wont exist before consuming it using the <from .../> tag.
Instead, you can construct a route for each consumer, normalize the exchange you receive from different types of consumers, and forward them to a common route for processing.
<route id="activemqConsumerRoute">
<from uri="activemq:doPost?..."/>
<!-- normalize the exchange to be understandable by the next route -->
<to uri="direct:commonProcessingRoute" />
</route>
<route id="sedaConsumerRoute">
<from uri="seda:doPost?....."/>
<!-- normalize the exchange to be understandable by the next route -->
<to uri="direct:commonProcessingRoute" />
</route>
<route id="commonProccessingRoute">
<from uri="direct:commonProcessingRoute" />
<!-- whatever business logic you have -->
</route>
I am new to Camel and I am trying to do the following.
I want to process the same message twice. I have to transform both messages and process one message first and then second only if the first one is sucessfully executed (I have a condition).
I tried to use a multicast first. Then I transform the messages in each route. The first one (the operation_DC) only sends a successfull message to the second one (the operation_AC) only if it is sucessfull. The second operation contains an aggregation that waits until it times out for both messages. I only want to process the messaged from the multicast and discard the other.
<route id="t_operation_ME">
<from uri="direct:operation_ME" id="t.direct.aggregatedService"></from>
<setHeader headerName="id">
<simple>exchangeId</simple>
</setHeader>
<multicast parallelProcessing="true" strategyRef="defaultAggregationStrategy" stopOnException="true" onPrepareRef="cleanHeader" parallelAggregate="false" completionPredicate="">
<to uri="direct:operation_DC"></to>
<to uri="direct:operation_AC"></to>
</multicast>
</route>
<route id="direct:operation_DC">
<from uri="direct:operation_DC" />
<log message="ENTER DC"></log>
<to uri="xslt:{{depasse:core.transformation.xml.path}}client/t/Operation_toDC_request.xsl" id="t.dc.transform.productos" />
<to uri="activemq:QCIn" id="t.dc.qcin.queue.send"></to>
<log message="EXIT DC ${body}"></log>
<choice>
<when>
<xpath>//Data/Status[. = 'OK']</xpath>
<log message="SEND TO AC"></log>
<to uri="direct:operation_AC"></to>
</when>
</choice>
</route>
<route id="direct:operation_AC">
<from uri="direct:operation_AC" />
<log message="ENTER AC"></log>
<aggregate completionTimeout="20000" completionSize="2" discardOnCompletionTimeout="true" strategyRef="tAggregationStrategy">
<correlationExpression>
<simple>header.id</simple>
</correlationExpression>
<log message="ENTER AGG AC ${body}"></log>
<to uri="xslt:{{depasse:core.transformation.xml.path}}client/t/Operation_toAC_request.xsl" id="t.ac.transform.productos" />
<to uri="activemq:QCIn" id="t.ac.qcin.queue.send"></to>
<log message="EXIT AC ${body}"></log>
</aggregate>
<log message="END AC\n${body}"></log>
</route>
The thing is that when I log "EXIT AC" and "END AC" the message is different. This means that while in the server I am watching the process correctly, the AC client receives an incorrect message.
Multicast send copy of messages always to every endpoint between tags. If you want to call route operation_AC only after operation_DC run successfully, you shouldn't use multicast, but you should save your body at the beginning of operation_DC, for example using property and Camel Simple:
<from uri="direct:operation_DC" />
<setProperty propertyName="body">
<simple>${body}</simple>
</setProperty>
and before calling operation_AC set body to bring message body from the beginning:
<setBody>
<simple>${property.body}</simple>
</setBody>
<to uri="direct:operation_AC"/>
Sorry for my english, I'll make my best effort for write this.
I have a xml file like this:
<routes>
<route id="id1">
<from uri="timer://foo?fixedRate=true&period=60s"/>
<onCompletion mode="BeforeConsumer">
<log message="finish"/>
</onCompletion>
<setBody>
<simple>Probando 1</simple>
</setBody>
<log message="working1"/>
<to uri="direct:test1"/>
</route>
<route id="id2">
<from uri="direct:test1"/>
<setBody>
<simple>Test2</simple>
</setBody>
<log message="working2"/>
<to uri="direct:test2"/>
</route>
<route id="id3">
<from uri="direct:test2"/>
<setBody>
<simple>Test3</simple>
</setBody>
<log message="working3"/>
</route>
</routes>
if remove mode="BeforeConsumer" from the first route i get one "finish" in the log, but if i use the xml with mode="BeforeConsumer" i get the message 3 times (one per each route). Is that the behavior expected?
I need that the onCompletion code runs one time but i need too the mode="BeforeConsumer"
