Service mix + camel + spring aop aspects

Hi,
I have implemented the following example http://cwiki.apache.org/SM/order-file-processing.html and it is working fine. I need to add few modifications to my camel context.xml. My question is , is it possible to add spring aspects to camel-context.xml i.e <?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://activemq.apache.org/camel/schema/spring http://activemq.apache.org/camel/schema/spring/camel-spring.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="camel" xmlns="http://activemq.apache.org/camel/schema/spring"> <package>org.camel.su</package> </camelContext> <bean id="firstAspect" class="org.aspect.FirstAspect"/> </beans> I have my pointcuts defined in the java code using spring annotations. The code is as follows: @Aspect public class SystemArchitecture { @Pointcut("execution(* *(..))") public void myFirstPointCut() { } } package org.aspect; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; @Aspect public class FirstAspect { @Around("SystemArchitecture.myFirstPointCut()") public void firstAspect(ProceedingJoinPoint joinPoint) { System.out.println("PRINTING FIRST ASPECT"); try { joinPoint.proceed(); } catch (Throwable e) { // TODO Auto-generated catch block e.printStackTrace(); } } } If defining aspects in camel-context.xml is possible, then how do I define aspects on my RouteBuilder class.Because I want a particular piece of code to be always executed before my route builder class is called and I do not want to embed that code in the routebuilder class. For ex: If I do some thing like this below, <?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://activemq.apache.org/camel/schema/spring http://activemq.apache.org/camel/schema/spring/camel-spring.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="camel" xmlns="http://activemq.apache.org/camel/schema/spring"> <routeBuilder ref="someRouterBuilder"/> </camelContext> <bean id="firstAspect" class="org.aspect.FirstAspect"/> <bean id="someRouterBuilder" class="org.camel.su.MyRouteBuilder"/> </beans> public class MyRouteBuilder extends RouteBuilder { @Override public void configure() throws Exception { System.out.println("IN ROUTE BUILDER#####"); // from our camelService which is called by the file poller from("jbi:service:http://servicemix.apache.org/example/orderProcessing") // we process the received order xml .process(new OrderProcessor()) // and send the result xml back to the file sender .to("jbi:service:http://servicemix.apache.org/example/fileSender"); } } I get an exception is saying that routeBuilder should of type org.apache.camel.builder.RouteBuilder. I do not understand why I am getting this exception as my RouteBuilder class is already extending the camel RouteBuilder class. Please help me these queries.I thank you all for your time. |

L.S.,
We should be able to get this to work, but I guess the way classes are loaded in JBI can make this just a bit harder -- some of the Spring AOP bits are being loaded from the JBI container classloader so we might have to add things there. Just a few informational questions before we start digging into this: - what version of servicemix are you using and which version of the servicemix-camel component? - could you make sure that you're using the same version of Camel in your own pom.xml (e.g. when defining extra components etc)? - can you send us the complete stack trace that you're seeing?

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 pom.xml

I believe I used service-mix-camel-service-unit while creating the service unit.To avoid the exception
unexpected element (uri:"http://camel.apache.org/schema/spring", local:"camelContext"), I think I would have to use camel-archetype-spring. My main concern is how to make the aspect run on routebuilder.

L.S.,
With this configuration, you're using jar files from three different Camel versions together: ServiceMix 3.2.3 comes with Camel 1.4.0 and I see references to 1.6.0 and 2.0-M2 in your pom.xml file. If you want to use Camel 1.6.0, I would strongly recommend you to upgrade to Servicemix 3.3.1 which ships with support for Camel 1.6.0. The only way to use Camel 2.0-SNAPSHOT/Mx in ServiceMix at the moment is by building the servicemix-camel component locally yourself (cfr. https://issues.apache.org/activemq/browse/SMXCOMP-563) Aligning on one single version of Camel will probably get rid of most of the Exceptions you're seeing...

L.S.,
For the plugin, you can use the latest version available (4.1). The components also no longer carry the same version number as the container, because they are now being shared between containers (e.g. servicemix-camel 2009.01 is being used in ServiceMix 3.3.1 and 4.0.0). ServiceMix 3.3.1 comes with servicemix-camel 2009.01 and uses Camel 1.6.0.

Re: Service mix + camel + spring aop aspects

I did this:
<plugin> <groupId>org.apache.camel</groupId> <artifactId>camel-maven-plugin</artifactId> <version>4.1</version> </plugin> After doing this, I am getting the following errors. Reason: Unable to download the artifact from any repository org.apache.camel:camel-maven-plugin:pom:4.1 from the specified remote repositories: central (http://repo1.maven.org/maven2), apache (http://people.apache.org/repo/m2-ibiblio-rsync-repository), apache.snapshots (http://people.apache.org/repo/m2-snapshot-repository) These r not present in the above locations.Do I need to add a new repository location where I would find the missing artifact. I was getting the similar error when I changed service mix version to 3.3.1 i.e <dependency> <groupId>org.apache.servicemix</groupId> <artifactId>servicemix-camel</artifactId> <version>3.3.1</version> </dependency> As you said , I am using 4.1 plugin , service mix version 3.3.1 and camel version 1.6

Can you please tell me the correct versions to use to avoid this error.I am pretty sure it is some jar version issue but when I try to change from one version to other, I get some new error. As I said in my previous post, I was getting artifacts not present at the location , so I thought to use service mix version 3.3.1-17 fuse. Thanks for your help.
