XmlBeanFactory and NullPointerException

Hi,
I'm pretty new with Spring, and I'm trying to start with my very first example but I can't get it working, my code is the following in the main method:

Code:

---

XmlBeanFactory factory = new XmlBeanFactory(new InputStreamResource(new FileInputStream("src/prueba/beans.xml")));

---

And my beans.xml, placed in the same package is 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="pruebaBean" class="prueba/PruebaBean" />
</beans>

---

If you need my PruebaBean code too please tell me, but it's pretty simple...
When I try to run this code I obtain the following (running in Eclipse):

Code:

---

Exception in thread "main" java.lang.ExceptionInInitializerError
        at prueba.PruebaApp.main(PruebaApp.java:28)
Caused by: java.lang.NullPointerException
        at org.springframework.beans.factory.support.DefaultListableBeanFactory.<clinit>(DefaultListableBeanFactory.java:104)
        ... 1 more

---

Please I need an answer because I've tryied almost everything!!! thanks in advance!

I suggest a basic java tutorial.... the class should be prueba.PruebaBean and not with a /...

yes of course, I copied it wrongly, but that doens't solve the problem at all...

Is the class "PruebaBean" in the package prueba and is it compiled while running the app?

Take a look at http://static.springsource.org/sprin...l#beans-basics

parvinder: Thanks!
I replaced my code with the following:

Code:

---

ApplicationContext ctx = new FileSystemXmlApplicationContext("src/com/prueba/beans.xml");

---

And it works like a charm!
