Aspectj in spring

I am getting the following error when i try to auto wire aspectj in spring

org.xml.sax.SAXParseException: The prefix "aop" for element "aop:aspectj-autoproxy" is not bound.


my appContext.xml entry looks like
.....

<aop:aspectj-autoproxy/>

<bean id="helloFromAspectJ" class="com.cvs.esps.aspect.logging.TestAspect"/>


.....

some help on how can i remove this error.. unfortunately the site http://forum.springsource.org is blocked by out network firewall.. any help fast will be highly appreciated.




here is what i get if i add the line

<bean id="loggerProxy" class="org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator" />

Answer

Actually to make things more clear i will include the appcontext.xml and the aspect class that i wrote

<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"
xmlns:cxf="http://cxf.apache.org/core"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-2.5.xsd
    http://cxf.apache.org/core
    http://cxf.apache.org/schemas/core.xsd
    http://cxf.apache.org/jaxws
    http://cxf.apache.org/schemas/jaxws.xsd"
xmlns:aop="http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop.xsd"

default-autowire="byName">

and the other entry

<aop:aspectj-autoproxy />
<!-- <bean id="loggerProxy" class="org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator" /> -->
<bean id="sampleAspectj" class="com.cvs.esps.aspect.logging.TestAspect"/>

AND THE ASPECT CLASS

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 TestAspect {
@Pointcut("execution(* getPatientDataJSON(..))")
public void logTestMessage(){}

@Before("com.cvs.esps.service.patient.PatientServiceImpl.doPostGetPatientDataJSON(..)")
public void sayHelloBefore(){
    System.out.println("*********************************************hello before");
}

@After("com.cvs.esps.service.patient.PatientServiceImpl.doPostGetPatientDataJSON(..)")
public void sayHelloAfter(){
    System.out.println("*********************************************hello after");
}
}
