spring inside eclipse

[preethi Ayyappan]

Hi,
I have downloaded and installed eclipse.I want to work in spring framework.But i am very new to spring and eclipse too.I have installed the spring ide(spring-ide_updatesite_2.0.0_v200706271108.zip) inside the eclipse through update manager site.Then i have tried a sample program in the new spring project.First i had selected the interface and typed the GreetingService.java in src folder in the NewSpringProject.

   
public interface GreetingService {
   public void sayGreeting();
}
 

Then i had typed the class file GreetingServiceImpl.java in src folder

  
public class GreetingServiceImpl implements GreetingService {
   private String greeting;
   public GreetingServiceImpl() {}
   public GreetingServiceImpl(String greeting) {
      this.greeting = greeting;
   }
   public void sayGreeting() {
      System.out.println(greeting);
   }
   public void setGreeting(String greeting) {
      this.greeting = greeting;
   }
}
  

After that I had selected an xml file and typed the following code

  
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
   "http://www.springframework.org/dtd/spring-beans.dtd">
 
<beans>
   <bean id="greetingService"
         class="com.springinaction.chapter01.hello.GreetingServiceImpl">
      <property name="greeting">
         <value>Buenos Dias!</value>
      </property>
   </bean>
</beans>
  

Finally i have typed the class file HelloApp.java

   
import java.io.FileInputStream;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
 
public class HelloApp {
   public static void main(String[] args) throws Exception {
      BeanFactory factory =
         new XmlBeanFactory(new FileInputStream("hello.xml"));
 
      GreetingService greetingService =
         (GreetingService) factory.getBean("greetingService");
 
      greetingService.sayGreeting();
   }
}
 

.
here I am getting the following errors:

BeanFactory cannot be resolved to a type
The import org.springframework cannot be resolved
XmlBeanFactory cannot be resolved to a type

.please guide me why i am getting the following errors and please anyone gude me how to work in spring initially.How to start a program basically in spring.

In Eclipse, in your project settings, did you set the spring.jar library ? Right-click your project, select Properties... In Java Build Path/Library, you need to add spring.jar.

How to start a program basically in spring.

By using an IDE you are comfortable with !

[preethi Ayyappan]

Thankyou.I have added the spring.jar. Now i am getting only one error.

The constructor XmlBeanFactory(FileInputStream) is undefined

Why is it so?

Is it tough working with an ide in initial stage?Then how should i start to work in spring.please do help me.I dont know anything about spring framework.

[Christophe Verré]

Why is it so?

Because if you look at Spring's API, you'll see that there is no such constructor in XmlBeanFactory. Maybe you wanted to write it like this :

BeanFactory factory = new XmlBeanFactory(new FileSystemResource("beans.xml"));

It's ok to use an IDE if you're not going to wasted hours trying to figure out how to configure something Well, it's compiling now, so you should be ok.

Hi,
Thanks for your reply.It is working fine.But when i give like this:

  
BeanFactory factory = new XmlBeanFactory(new ClassPathResource("hello.xml", HelloApp.class));
  

I am getting the following error:

just change the location of hello.xml file

like currently i assume your file should me in root directory of the application but you have to put this file in src folder , in my case i got same error so i changed the location and it is working fine.

Please let us know if you have any issue further.
