问题
I'm trying to expose a web service using fuse esb + apache camel + seda/activemq and I'm facing to an issue returing a status message to the web service call.
here is my simple camel route :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://camel.apache.org/schema/cxf"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd
http://camel.apache.org/schema/cxf http://camel.apache.org/schema/cxf/camel-cxf.xsd">
<cxf:cxfEndpoint id="msgInEndpoint" address="http://localhost:9000/msgin/"
serviceClass="com.test.jaxws.MsgInEndpoint">
</cxf:cxfEndpoint>
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route id="control">
<from uri="cxf:bean:msgInEndpoint" />
<to uri="log:incomingMsgIn" />
<to uri="seda:OpCon.MSGIN" />
<transform>
<constant>OK</constant>
</transform>
</route>
</camelContext>
</beans>
When I do a web service request using soapUI, in going to a timeout issue :
Exhausted after delivery attempt: 1 caught: org.apache.camel.ExchangeTimedOutException: The OUT message was not received within: 30000 millis.
The stacktrace cause :
Caused by: org.apache.camel.ExchangeTimedOutException: The OUT message was not received within: 30000 millis. Exchange[Message: $CONSOLE:DISPLAY,test]

I have the same result using seda or activemq as consumer, but it works fine with file consumer.
I'm on apache-servicemix-4.4.1-fuse-02-05 version.
Any idea of what I'm doing wrong? Thanks for your help
回答1:
When you send the message to the seda endpoint using
<to uri="seda:OpCon.MSGIN" />
And the message originates form a web service, then the message is using InOut as the Message Exchange Patterh (eg request/reply), which means Camel is expecting a 'reply' from the seda queue, in the sense it will wait for the message to be processed. But as the message is not processed, then a timeout of 30 sec is triggered, and why you see that exception. See the timeout options at: http://camel.apache.org/seda
Instead it looks like you want to send back asap an OK message to the web service, while sending a message to a queue for asynchronous further processing. There is an EIP for that, and its the WireTap EIP. So use that instead: http://camel.apache.org/wire-tap
<wireTap uri="seda:OpCon.MSGIN" />
回答2:
To fix the issue you can increase the timeout value or you can just disable timeout by using 0 or a negative value.
How to disable the timeout?
Ans: "seda:someName?timeout=0"
After setting timeout=0, you will not face timeout error.
