Example problem from Spring in Action AOP

[Bahadir Mert Uzan]

Hello everyone, I am very new to the Spring development and I want to learn in without going through expensive courses.
Because of that I bought a book Manning Spring in Action 2nd Edition. That book being much more understandable than other references
I try to follow every example with Netbeans IDE which supports Spring 2.5 library. Now I am stuck in the 2nd exercise of the first chapter
of the book.Here is the class I hope you are

 
package com.springinaction.chapter01.knight;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class KnightApp {
  public static void main(String[] args) throws Exception {
      try{
    ApplicationContext ctx = 
      new ClassPathXmlApplicationContext(
          "com/springinaction/chapter01/knight/knight.xml");

    Knight knight =
        (Knight) ctx.getBean("knight");

    knight.embarkOnQuest();
      }catch(Exception e){
          System.out.println("The problems\n"+e.getMessage());
      }
  }
}   

Try catch is for my self because otherwise it throws a huge number of errors. So far I can catch this error

The problems
Unexpected exception parsing XML document from class path resource [com/springinaction/chapter01/knight/knight.xml]; nested exception is java.lang.NoClassDefFoundError: org/aspectj/lang/JoinPoint    

This is the XML code that should do the trick but it doesn't

                pointcut-ref="questPointcut"
                arg-names="bean" />

            <aop:after-returning
                method="singAfter"
                pointcut-ref="questPointcut"
                arg-names="bean" />
        </aop:aspect>
    </aop:config>
</beans> 

I am a person who can understand things properly in their execution. So if you can help me that will be brilliant.
For the full code source code is available in http://www.manning.com/walls3/ and in that source code its chapter 1's knights example.
Once again a simple solution which I can do with Netbeans will be very appreciated.

Looks like you're missing library dependencies.

I have both used netbeans 2.5 Spring library, downloaded the zip version with dependencies and add it to my project.
Doesn't solve it. :(

[David Newton]

What libraries are you deploying?

[Bahadir Mert Uzan]

David Newton wrote:What libraries are you deploying?

Spring Framework 2.5 -
commons-logging-1.1.jar
cglib-2-2.jar
-spring-2.5.jar (sorry it's a little late in here)
alse everything from Spring-framework-2.5.6.Sec01 zip

[David Newton]

What's "soring-2.5.jar"? In any case, when you say "everything", it'd really be a LOT more useful if you just told us what you're deploying, rather than making us do all the work.

A very simple java application with java classes. Its about 9 simple classes and I am trying to learn AOP. I ll show you how easy the classes are.

    package com.springinaction.chapter01.knight;


public class KnightOfTheRoundTable implements Knight {
  private String name;
  private Quest quest;
  
  public KnightOfTheRoundTable(String name) {
    this.name = name;
  }
  
  public Object embarkOnQuest() throws QuestFailedException {
    return quest.embark();
  }
  
  public void setQuest(Quest quest) {
    this.quest = quest;
  }
  
  public String getName() {
    return name;
  }
}

and the other class

   package com.springinaction.chapter01.knight;

import org.apache.log4j.Logger;

public class Minstrel {
  private static final Logger SONG = 
      Logger.getLogger(Minstrel.class);

  public Minstrel() {}
  
  public void singBefore(Knight knight) {
    SONG.info("Fa la la; Sir " + knight.getName() +
        " is so brave!");
  }
  
  public void singAfter(Knight knight) {
    SONG.info("Tee-hee-he; Sir " + knight.getName() +
        " did embark on a quest!");
  }
}

Not what I asked. I asked you to list, specifically, the libraries you're deploying. Or maybe how you're trying to run it. One way or another, the missing class isn't there when the program is being run.

just add this library : aspectjrt.jar ---> (spring-framework-2.5.6.SEC01\lib\aspectj)

Hope this could help.

Yes I add both aspectjrt.jar and aspectweaver.jar and it works. Strange I thought these would have resided in Spring Libraries that Netbeans have.
Thanks everyone.
About Deployment I don't know the details but netbeans usually do jar modification and other stuff it self. I don't think it does anything fancy.

[David Newton]

"Jar modification"? "Deployed" means "what jars are on the classpath when you execute the program."

I deploy them with these libraries attached.
(these are from libraries in Netbeans Spring Framework2.5)
commons-logging-1-1.jar
cglib-2.2.jar
spring2.5.jar

and these 2 that solved the problem

aspectjrt.jar
aspectweaver.jar

[David Newton]

Yes, I saw that it was already solved. I was trying to clear up your confusion about terminology.
