Question

How do I load resources like images from the java code with Jboss7.1?

This used to work with Jboss4:

this.getClass().getClassLoader().getResourceAsStream("/myapp/includes/images/image1.png");

Now this returns null.

What is best practice for loading resources in java code now with Jboss7?

I did some testing:

URL url = this.getClass().getResource("");
System.out.println(url);
url = this.getClass().getResource("../../../");
System.out.println(url);
url = this.getClass().getResource("../../../../");
System.out.println(url);
url = this.getClass().getResource("../../../../../");
System.out.println(url);
url = this.getClass().getResource("includes");
System.out.println(url);

As documented on the JBoss community wiki (without using a jboss-deployment-structure.xml file):

1. Create a module for the configuration file (jboss-as-7/modules/com/yourcompany/configuration/main/module.xml):

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.mycompany.configuration">
    <resources>
        <resource-root path="."/>
    </resources>
</module>

2. Add properties to the module:

jboss-as-7/
   modules/
      com/
         yourcompany/
            configuration/
               main/
                 module.xml
                 settings.properties
                 other-settings.xm

3. Add the module to the CLASSPATH using a MANIFEST.MF entry:

Manifest-Version: 1.0
Dependencies: com.mycompany.configuration

4. Load a properties file from the CLASSPATH:

InputStream settingsStream = 
  getClass().getClassLoader().getResourceAsStream("settings.properties");

I had to create a module folder called com/mycompany/main and add all the images in there. So this sits outside the WAR at least though within JBOSS_HOME. Then I could load the image using:

URL imgUrl = this.getClass().getClassLoader().getResource("myimage.jpg");
