Hi,
I will tell u the complete procedure that I followed.
1)Created the various service units and assemblies corresponding to the
example:
http://cwiki.apache.org/SM/order-file-processing.html
2) In order to try spring aspects , I did all possible steps required for it
i.e defining the pointcuts etc.
My camel-context.xml looked like the one pasted in the previous.
3) After deploying it in service mix, I got exception ..RefelectionUtils .
isNotEqualMethod not defined.
I changed the camel version in the pom.xml to avoid this error. The relevant
portion of pom.xml currently is like this:
<plugin>
<groupId>org.apache.camel</groupId>
<artifactId>camel-maven-plugin</artifactId>
<version>1.6.0</version>
</plugin>
<dependency>
<groupId>org.apache.servicemix</groupId>
<artifactId>servicemix-camel</artifactId>
<version>${servicemix-version}</version>
</dependency>
<dependency>
<groupId>org.apache.servicemix</groupId>
<artifactId>servicemix-core</artifactId>
<version>${servicemix-version}</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-spring</artifactId>
<version>2.0-M2</version>
</dependency>
</dependencies>
<properties>
<servicemix-version>3.2.3</servicemix-version>
<!-- <camel-version>1.4.0</camel-version>-->
<camel-version>1.6.0.0-fuse</camel-version>
</properties>
4) After doing this , the aspect was not being called.I think the pointcut
expression i.e the method which the aspect was defined, its class was not
being loaded by spring framework.
5)So I tried to create an aspect on the route builder class.I changed my
camel-context.xml to the following:
<?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:camel="http://camel.apache.org/schema/spring";
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://camel.apache.org/schema/spring/camel-spring.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd
">
<context:annotation-config />
<aop:aspectj-autoproxy/>
<camelContext id="camel5" xmlns="http://camel.apache.org/schema/spring";>
<routeBuilder ref="myBuilder" />
</camelContext>
<bean id="myBuilder" class="org.camel.su.MyRouteBuilder"/>
<bean id="firstAspect" class="org.aspect.FirstAspect"/>
</beans>
I changed my point cut expression so that my advice gets called before the
routebuilder configure method.
But now I am getting an exception
unexpected element (uri:"http://camel.apache.org/schema/spring";,
local:"camelContext").It is expecting all uris having activemq.
I have attached my camel-su pom.xml for your reference
