load time weaver and tomcat 6 problem!

[Muttley]

Dear Spring community

what have i missed?

I am trying to get load-time-weaver working in spring 3
on tomcat 6 in eclipse Eclipse Java EE IDE for Web Developers.

Build id: 20090920-1017

i have followed the instructions given here

7.8.4 Load-time weaving with AspectJ in the Spring Framework

heres my aspect
package com.pre.school.aop;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class KevynAucoin extends BaseAspect {

/**
* A join point is in the Data Access Object layer if the method is defined
* in a type in the com.pre.school.persistent.hibernate package or any
* sub-package under that.
*/
@Pointcut("within(com.pre.school.dao..*)")
public void inDataAccessObjectLayer() {
}

/**
* the execution of any method with a name beginning with "set"
*/
@Pointcut("execution(* com.pre.school.dao.*.*(..))")
public void setBeechey() {
}

@Around("inDataAccessObjectLayer()")
public Object doSetting(ProceedingJoinPoint pjp) throws Throwable {
Object retVal = pjp.proceed();
return retVal;
}

}

heres my aop.xml in META-INF
<!DOCTYPE aspectj PUBLIC
"-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>

<weaver>

<!-- only weave classes in our application-specific packages -->
<include within="com.pre.school.dao.*" />

</weaver>

<aspects>

<!-- weave in just this aspect -->
<aspect name="com.pre.school.aop.KevynAucoin" />

</aspects>

</aspectj>

this my spring config for aspect

<?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:context="http://www.springframework.org/schema/context"

http://www.springframework.org/schema/context/spring-context-3.0.xsd">


<bean id="preSchoolPresentationAspects" class="com.pre.school.aop.KevynAucoin" />

<!-- this switches on the load-time weaving -->
<context:load-time-weaver />

</beans>

heres my tomcat 6 context.xml

<Context path="/Aardvark">
<Loader loaderClass="org.springframework.instrument.classl oading.tomcat.TomcatInstrumentableClassLoader"/>
</Context>

the thing is my tomcat 6 install doesnt appear to have a $CATALINA_HOME/server/lib folder! why is that?

so i cant follow this instruction
"Copy org.springframework.instrument.tomcat.jar into $CATALINA_HOME/server/lib, where $CATALINA_HOME represents the root of the Tomcat installation."

so i put this jar "org.springframework.instrument.tomcat-3.0.0.RELEASE.jar"
in the $CATALINA_HOME/lib folder

one question i have is... how do you work out what your docbase is in this

<Context path="/myWebApp" docBase="/my/webApp/location">
<Loader
loaderClass="org.springframework.instrument.classl oading.tomcat.TomcatInstrumentableClassLoader"/>
</Context>

I have now managed to get aspects working fine...

As long as i always follow these steps

1). Clean Tomcat server
2). Start server
3). Test ... everything ok

if i now stop and start the tomcat server (without clean)
the aspects do not get weaved!

This is within eclipse (galileo)

Why Why Why ? do i have to clean before every server start?
