How to add resources in Maven Classpath

Question

I am new to Spring and Maven. I am trying to build a spring app using maven archetypes. So i have set up the project with maven pom.xml. All things work fine but the only issue is my IDE (netbeans) is not including my spring.xml in the classpath. As a result the build fails with file not found exception. I have to specifically give the fully qualified path of the spring.xml to get this working.

So the below fails - AbstractApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");

If i change it as below it works -

AbstractApplicationContext context = new ClassPathXmlApplicationContext("file:///Users/shoukat/NetBeansProjects/csm/src/main/java/spring.xml");

I find that this is happening because my classpath does not include the main/java directory. Below are the results when i try to print the classloader URLs using the below code-

        ClassLoader sysClassLoader = ClassLoader.getSystemClassLoader();

        //Get the URLs
        URL[] urls = ((URLClassLoader)sysClassLoader).getURLs();

        for(int i=0; i< urls.length; i++)
        {
            System.out.println(urls[i].getFile());
        }

Result -

/Users/shoukat/NetBeansProjects/csm/target/classes/
/Users/shoukat/.m2/repository/commons-logging/commons-logging/1.1.3/commons-logging-1.1.3.jar
/Users/shoukat/.m2/repository/org/hamcrest/hamcrest-core/1.3/hamcrest-core-1.3.jar
/Users/shoukat/.m2/repository/org/slf4j/jcl-over-slf4j/1.7.5/jcl-over-slf4j-1.7.5.jar
/Users/shoukat/.m2/repository/org/slf4j/slf4j-api/1.7.5/slf4j-api-1.7.5.jar
/Users/shoukat/.m2/repository/org/springframework/spring-context/4.0.0.RELEASE/spring-context-4.0.0.RELEASE.jar
/Users/shoukat/.m2/repository/org/springframework/spring-aop/4.0.0.RELEASE/spring-aop-4.0.0.RELEASE.jar
/Users/shoukat/.m2/repository/aopalliance/aopalliance/1.0/aopalliance-1.0.jar
/Users/shoukat/.m2/repository/org/springframework/spring-beans/4.0.0.RELEASE/spring-beans-4.0.0.RELEASE.jar
/Users/shoukat/.m2/repository/org/springframework/spring-core/4.0.0.RELEASE/spring-core-4.0.0.RELEASE.jar

Ideally this should also include the src directory as i am putting my resources spring.xml file in there. What do i need to change so the my src/main directory is included in classpath and i do not have to hardcode my program with the fully qualified system path of my spring.xml file?

Thanks

When using ClassPathXmlApplicationContext search spring.xml in your classpath but maven when compile ignore resources like * .xml put in src/main/java

For this to work you have to create the resource folder and the folder tree is like:

src/main/java/..
src/main/resources/spring.xml

Then you can use:

AbstractApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
