LTW + Spring

[joni.loky]

Hi, I'm trying to use Load-Time Weaving with spring but I just can't get it to work.

this is my META-INF/aop.xml file:

<aspectj>

<weaver>

<!-- only weave the following classes -->
<include within="ar.mycompany.cda..*"/>

</weaver>

<aspects>

<!-- weave in just this aspect -->
<aspect name="ar.mycompany.cda.aop.LoadTimeWeaving"/>

</aspects>
</aspectj>

this is my aspect:

package ar.mycompany.cda.aop;

import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class LoadTimeWeaving {

Logger logger;

@Before("loggeoCDA()")
public void logBefore(JoinPoint jp){
logger = Logger.getLogger(jp.getTarget().getClass());
logger.debug("INICIO: " + obtenerFirmaCompleta(jp));
}

@After("loggeoCDA()")
public void logAfter(JoinPoint jp){
logger = Logger.getLogger(jp.getTarget().getClass());
logger.debug("FIN: " + obtenerFirmaCompleta(jp));
}

@Pointcut("execution(* ar.mycompany.cda..*.*(..))")
public void loggeoCDA(){}

private String obtenerFirmaCompleta(JoinPoint jpoint){
StringBuffer buffer = new StringBuffer();
buffer.append(jpoint.getTarget().getClass().getSim pleName() + "." + jpoint.getSignature().getName() + "(");

Object[] args = jpoint.getArgs();
for (int i = 0; i < args.length; i++) {
Object arg = args[i];
buffer.append(arg.getClass().getSimpleName()+" arg"+i);
if (i+1<args.length){
buffer.append(", ");
}
}
buffer.append(")");
return buffer.toString();
}
}

and finally this is my spring-beans.xml config:

<?xml version="1.0" encoding="UTF-8"?>

</beans>

I'm setting the -javaagent:C:/Spring-Agent/spring-agent.jar as a VM parameter. The app runs as if nothing happened. I know the <context:load-time-weaver/> tag is being noticed because if i don't specify the -javaagent param for the VM I get an exception.

Did I miss something configuring LTW? I'm using JAVA 5.
