Hi, I am trying to do an aggregation pattern using camel
Here is my java code and here is the camel-context.xml
<camelContext id="camel"
xmlns="http://activemq.apache.org/camel/schema/spring";>
<routeBuilder ref="myBuilder" />
</camelContext>
<bean id="myBuilder" class="com.nsn.hiq.test.MyRouteBuilder"/>
public class MyRouteBuilder extends RouteBuilder {
public void configure() {
// TODO create Camel routes here. For example:-
//
// from("activemq:test.MyQueue").to("file://test");
/*from("timer://tutorial?fixedRate=true&delay=3000&period=10000") // 1
.setBody(constant("<message>Hello world!</message>"))
// 2
.to("log:tutorial");
*/
from("jbi:service:http://servicemix.apache.org/test/camel-receiver";)
.aggregate().xpath("/p:snmp-getResponse/p:NE/@ipaddr",
String.class)
.completionSize(1)
//.to("jbi:endpoint:http://servicemix.apache.org/test/file_sender_getbulk/endpoint";);
// 3
.to("log:tutorial");
}
}
To compile the java code I need camel-core at least 2.3.0
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-core</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>2.5.6</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>2.5.6</version>
</dependency>
However the moment I give this came-core 2.3.0 and try to deploy it in
servicemix 3.3.1 I get a depolyment error.
I tried to use the se\pring xml without the java code, but I have not
figured how to get the correlationExpression proper as I am getting no
result out of it. Any suggestions appreciated ( I cannot change the
servicemix version as this is outside my control)

Here is the spring xml for camel which does not throw any errors, but does
not seem to work properly
<camelContext id="camel"
xmlns="http://activemq.apache.org/camel/schema/spring";>
<route>
<from
uri="jbi:service:http://servicemix.apache.org/test/camel-receiver"; />
<aggregate completionSize="1" groupExchanges="true" >
<correlationExpression>
<jxpath>/p:snmp-getResponse/p:NE/@ipaddr</jxpath>
</correlationExpression>
<to
uri="jbi:endpoint:http://servicemix.apache.org/test/file_sender_getbulk/endpoint";
/>
<to uri="log:tutorial"/>
</aggregate>
</route>
</camelContext>
