Answer 1

Do you have a namespace declaration in your tag? Something like this:

<beans 
xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
...>

Answer 2

I had the same problem and solved it by arranging namespace and schemalocation as 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:p="http://www.springframework.org/schema/p"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:aop="http://www.springframework.org/schema/aop" 
        xsi:schemaLocation="
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd 
            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"
        default-destroy-method="destroy"
        default-init-method="afterPropertiesSet"
        default-autowire="byName"
>

Notice that the schemalocation contains both uri:s, the one declared for xmlns:aop and the one for the xsd-file

Answer 3

You can define the namespace for AOP in your xml file.......

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:mvc="http://www.springframework.org/schema/mvc"
     xmlns:context="http://www.springframework.org/schema/context"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans     
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/mvc 
      http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop.xsd">

copy and paste the aop lines

Answer 4

You have the namespace declaration for aop but you lack the xsi:schemaLocation for the aop as well. check the 'context' schema usage (it appears also in the schemaLocation)

Answer 5

Please convert your project to aspectj project by downloading aspectj jars and copying them to eclipse plugin and feature folders correspondingly.

When you do this then restart Eclipse , right click on project and you will find some aspecj Tools option over there then you can convert to aspectj selecting source as aspectj .
