org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'id' is defined

[Satyajeet Kadam]

Q1)Please let me what has gone wrong in beans.xml?. I am getting error as "org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'id' is defined " when i run the program.


Main.java

   
package com.kogent;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import org.springframework.context.ApplicationContext;
public class Main 
{
  public static void main(String args[])
  {
 //   ApplicationContext acx=new ClassPathXmlApplicationContext("beans.xml");
    ApplicationContext acx=new FileSystemXmlApplicationContext("C:/Documents and Settings/satyajit/My Documents/NetBeansProjects/Aop/build/classes/com/kogent/beans.xml");
    // ApplicationContext acx=new ClassPathXmlApplicationContext("com/kogent/beans.xml"); 
    Code ob=(Code)acx.getBean("id");
    ob.display();
  
  }
}

 

Code.java

  

package com.kogent;
public class Code 
{
  public void display()
  {
    System.out.println("Hello World");
  }
  
}
 

Asp.java

 
package com.kogent;
//import org.aspectj.lang.annotation.Aspect;
//import org.aspectj.lang.annotation.AfterReturning;
//import org.aspectj.lang.annotation.Before;
public class Asp 
{
  
  public void mainMethod()
  {
     System.out.println("Hello from @Before Annotation in Aspectj");
  }
 
  
  public void myMethod()
  {
       System.out.println("Hello from @AfterReturning Annotation in Aspectj");
  }
}

beans.xml

Well, Main.java:13 tries to get a bean named "id", and there isn't one. I suspect you meant "name", which is also not terribly clear.

Also, when posting code/stacktraces/etc. please make sure to wrap very long lines, otherwise we have to scroll to the right quite far in order read your post, edit our post, etc.

[Satyajeet Kadam]

Thanks for your reply.

Event after changing this line from

   

 Code ob=(Code)acx.getBean("id");
 

to this line.

  
  Code ob=(Code)acx.getBean("name");

I am still getting the error?

[David Newton]

What do you mean, "still getting the error"? That's a completely different error.

[Satyajeet Kadam]

I am Sorry.I appreciate you have helped me. But i mean that i am still getting new error. Can you please helpe me?

[Mark Spritzler]

This is your error

Caused by: java.lang.IllegalArgumentException: error at ::0 can't find referenced pointcut display

So there appears to be something wrong in your AOP configuration. Either your pointcut is incorrect, or you are using a named pointcut and the Advice is trying to
point to the name, and it is an incorrect name.
