Hi People,

i downloaded the latest code for beginning Spring 2. Since the code base does not include sample for AOP i tried to add some AOP features to the Pix application.

i added the following segment to the pix-servlet.xml

<aop:config>
        <aop:pointcut id="samplePointcut"
                      expression="execution(com.wrox.beginspring.pix.dao .persistUser(..))"/>

        <aop:aspect id="sampleAspect" ref="advice">
            <aop:around method="lookup" pointcut-ref="samplePointcut"/>
        </aop:aspect>
    </aop:config>

    <bean id="advice" class="com.wrox.beginspring.pix.cache.CacheService "/>

also implemented the class wrox.beginspring.pix.cache.CacheService with the method "lookup"

When i try to deploy first it gaves a ClassNotFoundException with the class name org.objectweb.asm.commons.EmptyVisitor
This class is there in the asm-commons-2.2.1.jar.
Once i added this jar back again it says ClassNotFoundException for org.objectweb.asm.FieldWriter.

this class(FieldWriter)is not there in the asm-1.5.3.jar but it is there in the asm-3.1.jar.

when i add this jar (after deleting asm-1.5.3.jar ) it gives the following error.

hodError: org.objectweb.asm.ClassWriter.<init>(Z)V

which version of the asm jar file should be added ?
