spring utility project - java.io.FileNotFoundException on Ubuntu

Question

I'm newly at Spring. I tried to write easy project and stack with weird exception FileNotFoundException.

To my mind it is some problem with loading app-context.xml. But I sure that set correct absolute path.

Any suggestions?

Main code:

package com.prospring.ch2;

public class HelloWorldSpringDI {

    public static void main(String[] args) {
        ApplicationContext ctx = new ClassPathXmlApplicationContext(
                "/home/nazar_art/workspace/ch2/src/main/resources/META-INF/spring/app-context.xml");
        MessageRenderer mr = ctx.getBean("renderer", MessageRenderer.class);
        mr.render();
    }
}

Here content of app-context.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"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <bean id="provider" class="com.prospring.ch2.HelloWorldMessageProvider" />
    <bean id="rendere" class="com.prospring.ch2.StandartOutMessageRenderer" 
        p:messageProvider-ref="provider" />

    <!--<description>Example configuration to get you started.</description --> 
    <!-- context:component-scan base-package="com.prospring.ch2" />  -->
</beans>

snippet of console message:

14:24:06,360  INFO t.support.ClassPathXmlApplicationContext: 456 - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@3f62e847: startup date [Wed Nov 13 14:24:06 EET 2013]; root of context hierarchy

I checked path to app-context.xml from terminal all looks ok:

nazar_art@nazar-desktop:~/workspace/ch2/src/main/resources/META-INF/spring$ pwd
/home/nazar_art/workspace/ch2/src/main/resources/META-INF/spring
nazar_art@nazar-desktop:~/workspace/ch2/src/main/resources/META-INF/spring$ ls -lg
total 4

Here is looking of my struckture:

Answer 1

You are using the class path application context loader ClassPathXmlApplicationContext and passing an absolute path to it.

You need to use FileSystemXmlApplicationContext

If you want to use ClassPathXmlApplicationContext then you have to make sure your app-context.xml is in the class path of your application and pass the appropriate resource name, which is different from the absolute path on a filesystem.

Answer 2

Use either

public static void main(String[] args) {
    ApplicationContext ctx = new FileSystemXmlApplicationContext(
            "/home/nazar_art/workspace/ch2/src/main/resources/META-INF/spring/app-context.xml");
    ...
}

or

public static void main(String[] args) {
    ApplicationContext ctx = new ClassPathXmlApplicationContext(
            "META-INF/spring/app-context.xml");
  ...
}

FileSystemXmlApplicationContext

ClassPathXmlApplicationContext
