is there a anyway to create a proxy in spring other than using ProxyFactoryBean ?

is there any other way to impliment ProxyFactoryBean a than creating this way?
<bean id="adder" class="org.springframework.aop.framework.ProxyFactoryBean">

this is my impl class
package com.spring.aop; public class AdderImpl implements Adder { public int add(int a, int b){ return a+b; } }

this is my advice
package com.spring.aop; import java.lang.reflect.Method; import org.springframework.aop.MethodBeforeAdvice; public class LogBeforeCallAdvice implements MethodBeforeAdvice{ public void before(Method method, Object[] args, Object target) { System.out.println("Before Calling the Method"); } }

this is my test class
package com.spring.aop; import org.springframework.beans.factory.BeanFactory; import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import org.springframework.core.io.*; public class AdderTest { public static void main(String args[]){ ApplicationContext factory =new ClassPathXmlApplicationContext("hello.xml"); Adder adder = (Adder)factory.getBean("adder"); int result = adder.add(10,10); System.out.println("Result = " + result); // result = adder.add(0,0); System.out.println("Result = " + result); } }

this is my xml file
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> <bean id="beforeCall" class="com.spring.aop.LogBeforeCallAdvice" /> <!-- Implementation Class --> <bean id="adderImpl" class="com.spring.aop.AdderImpl" /> <!-- Proxy Implementation Class --> <bean id="adder" class="org.springframework.aop.framework.ProxyFactoryBean"> <property name="proxyInterfaces"> <value>com.spring.aop.Adder</value> </property> <property name="interceptorNames"> <list> <value>beforeCall</value> </list> </property> <property name="target"> <ref bean="adderImpl" /> </property> </bean> </beans>

this examle working fine.
but my problem is where is the pointcut in this example?

this is my dog class
package Test; import java.util.Collection; import com.aruna.Animal; public class Dog implements Animal { private Chicken ch; private Collection<Cats> cat; public Collection<Cats> getCat() { return cat; } public void setCat(Collection<Cats> cat) { this.cat = cat; } public Dog() { } public Dog(Chicken c) { System.out.println("Dog Eattttttttttttttttttttttttt"); ch=c; } @Override public void eat() { System.out.println("Dog Eattttttttttttttttttttttttt"); if(ch!=null){ ch.LayEgg(); } } public Chicken getCh() { return ch; } public void setCh(Chicken ch) { this.ch = ch; } }

this is my xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> <bean id="mydog" class="Test.Dog"></bean> <bean id="chicken" class="Test.Chicken"> <property name="leg" value="3"></property> </bean> <bean id="ab" class="Test.Cats"></bean> <bean id="cd" class="Test.Cats"></bean> <bean id="ef" class="Test.Cats"></bean> <bean id="secondDog" class="Test.Dog"> <constructor-arg ref="chicken"></constructor-arg> <property name="cat"> <list> <ref bean="ab"/> <ref bean="cd"/> <ref bean="ef"/> </list> </property> </bean> </beans>


this is my cat class
package Test; public class Cats { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } }

this is my main class
package Test; import java.util.Collection; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class MainApp { public static void main(String args[]){ ApplicationContext ctx = new ClassPathXmlApplicationContext("my.xml"); //Dog test=(Dog)ctx.getBean("mydog"); //test.eat(); Dog second=(Dog)ctx.getBean("secondDog"); Chicken c=second.getCh(); System.out.println("legsssssssssssssssssssss "+c.getLeg()); second.eat(); Collection<Cats> d=second.getCat(); System.out.println("xxxxxxxxxxxxxxxxxxxxxx "+d); } }

when i run i get out put as follow
xxxxxxxxxxxxxxxxxxxxxx [Test.Cats@704baa, Test.Cats@77a7f9, Test.Cats@1b4fad5]

how to get cat objects from collection d??

lets imagin i don't like to put my xml file to src folder.
so i need it to put Diretly to project folder.

1)if i did that way how can i use ClassPathXmlApplicationContext to load beans?
2)or is there any other best way to do this other than using src folder?

I am reading Spring in Action book.
it saying that beans has life cycle several steps.
3 rd one is Set bean name =If the bean implements BeanNameAware, Spring passes thebean’s ID to setBeanName().

1)my question is what is BeanNameAware interface?
2)when do we impliment that interface?

I put a jboss-web.xml file inside the project and make a war file.
here is jboss-web.xml
<jboss-web> <context-root>TicketSystem</context-root> </jboss-web>

but the starting line of this xml file give this message

No grammar constraints (DTD or XML schema) detected for the document.

when i start jboss server and type this in IE
http://localhost:8080/Abc/

it is working.it gives expected results.
but when i type this
http://localhost:8080/TicketSystem
it says
type Status report message /TicketSystem description The requested resource (/TicketSystem) is not available. JBoss Web/2.1.3.GA

i don't know why?

project attached as a zip file

the problem is that i created a war file without a jboss-web.xml fle.
But it is also working.
my problem is how it is working without a jboss-web.xml.

I change the name of war file to Abc.war.
now i type http://localhost:8080/Abc/ in Explore.
it is working fine.
but still i am unable to fine extracted war file in tem folder.

it is working fine.
anyway i put a war file without a jboss-web.xml file.
it is also working fine.
1)i don't know why?
2)can you tell me where is the place to jboss extract the war files?

ok.
here is my jboss-web.xml file

<jboss-web> <context-root>TicketSystem</context-root> </jboss-web>

it in WebContent folder of my web application.
is it ok now.
