where to put the XML file for dependency injection.

[Niranjan Deshpande]

Hi all,

I am trying to run a sample Dependency Injection code from Spring in Action Book's chapter 1. The application that sets the ball rolling is -

public class KnightApp {
 
public static void main(String[] args) throws Exception {
BeanFactory factory = new XmlBeanFactory(new             
                FileSystemResource  ("knight.xml"));
Knight knight = (Knight) factory.getBean("knight");
knight.embarkOnQuest();
}
}

But when I try to run the code, I get this exception -

Feb 21, 2008 9:51:40 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions
INFO: Loading XML bean definitions from file [C:\Workspace\springTest\knight.xml]
Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from file [C:\Workspace\springTest\config\knight.xml]; nested exception is java.io.FileNotFoundException: config\knight.xml (The system cannot find the file specified)

at com.springinaction.chapter01.knight.KnightApp.main(KnightApp.java:14)

Please let me know where should I put my knight.xml. I am using this file just to inject some dependencies into the Knight object.

What are other ways of loading these XML? The folder structure that I am using is -

springTest/src/*.java are placed
springTest/knight.xml

In your case the xml file would need to be directly where you are running your code from so in your case it is looking in

C:\Workspace\springTest\config\knight.xml

There are several different factories for grabbing the descriptor files. Just take a look at the Spring docs.

Hi

The problem is solved now. I simple corrected the file name from knight to
knight.xml

But I am getting the following stack trace now -

I am using spring-framework-2.0.6
I read some where that the sring.jar's version matters, whether your are using 2.04rc blah blah.. something like that.

Please help me out.

Hi

the applicaiton is working now. I just changed

<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">

to

<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">

You can make out the difference

But now I am trying to add some AOP stuff to my application and I got this exception:

The prefix "aop" for element "aop:config" is not bound.

What can be wrong now?

hi,

you can download the code from http://www.manning.com/walls3/
Then you'll see what's missing.
