Failed to Read Schema for spring-aop-2.0.xsd

[just_a_kid83]

Hi i get this error message below when is was testing my sampe application copied from Chapter 6. Aspect Oriented Programming with Spring

schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/aop/spring-aop-2.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
	at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source)

Below is my SpringAop.xml

<beans xmlns="http://www.springframework.org/schema/beans"
      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-2.0.xsd
      http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">

   <!-- this is the object that will be proxied by Spring's AOP infrastructure -->
   <bean id="fooService" class="biz.DefaultFooService"/>

   <!-- this is the actual advice itself -->
   <bean id="profiler" class="biz.SimpleProfiler"/>

   <aop:config>
      <aop:aspect ref="profiler">

         <aop:pointcut id="theExecutionOfSomeFooServiceMethod"
                    expression="execution(* biz.FooService.getFoo(String,int))
                    and args(name, age)"/>

         <aop:around pointcut-ref="theExecutionOfSomeFooServiceMethod"
                  method="profile"/>

      </aop:aspect>
   </aop:config>

</beans>

Any My Boot java is as below

import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;


public final class Boot {

   public static void main(final String[] args) throws Exception {
      BeanFactory ctx = new ClassPathXmlApplicationContext("SpringAop.xml");
      FooService foo = (FooService) ctx.getBean("fooService");
      foo.getFoo("Pengo", 12);
   }
}

Any idea?
i copied this example from Spring Chapter and i run i ran to above error.

Thanks

Hi

Okay for the time being it is okay ,
what i did i save as the aop.xsd and save in my local computer

but after i test . i didnt see any interceptor lines

here is my output

NAME +++>Pengo

my Foo Service as below

interface FooService {

	   String getFoo(String fooName, int age);
	}


public class DefaultFooService implements FooService {

	   public String getFoo(String name, int age) {


		   System.out.println("NAME +++>"+name);
		   
		   return "1";
	   }
	}

My Profiles is as below

import org.aspectj.lang.ProceedingJoinPoint;
import org.springframework.util.StopWatch;

public class SimpleProfiler {

   public Object profile(ProceedingJoinPoint call, String name, int age) throws Throwable {
      StopWatch clock = new StopWatch(
            "Profiling for '" + name + "' and '" + age + "'");
      System.out.println("PROFILING for "+name);
      try {
         clock.start(call.toShortString());
         return call.proceed();
      } finally {
         clock.stop();
         System.out.println(clock.prettyPrint());
      }
   }
}

Anything wrong with my code??
By right if this one works , i should be able to see "PROFILING" String


here is my SpringAop.xml

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

         <aop:around pointcut-ref="theExecutionOfSomeFooServiceMethod"
                  method="profile"/>

      </aop:aspect>
   </aop:config>

</beans>

Any Idea Guys?

Or do you have any simple working example for interceptors using Spring Aop?

Thanks

I have run your example using spring 2.0.3 snapshot and the interceptor works fine. Which version of spring is being used?
My output is:

PROFILING for Pengo
NAME +++>Pengo
StopWatch 'Profiling for 'Pengo' and '12'': running time (millis) = 10
-----------------------------------------
ms     %     Task name
-----------------------------------------
00010  100%  execution(getFoo)

Probably you do not have spring-aop.jar in your path
