java - How to pack resources in a Maven Project?

Question

I am looking for suggestion in putting image file maven web project. One of classes under src/main/java need to use an image file. My problem is, if i put image file under src/main/webapp/images as well as under src/main/resources/Images then application server cannot find that path on runtime(where myeclipse can ) because war archive do not have specified path "src/main/webapp/images".

My question is where should i put the image file that my project can find it without prompting any error or exception.

I am using

• Java Web Application with Mavenized falvour
• MyEclipse 10
• Application Server: JBoss 6

Currently i do have following dir structure

Project Directory Structure

-src/main/java
      -- classes
  -src/main/resources
     -- applicationContext.xml
  -src/main/resources/Images
      -- myImage.png (target image)
  -src/test/java
      -- test classes
  -src/test/resources
       (nothing)

  -src
    -- main
        --- webapp
              --WEB-INF
                 ---faces-config.xml
                 ---web.xml
              --Images
                 --OtherImages
                 --myImage.png( second place for image)
              --Css
              --Meta-INF
              --login.jspx
              --jsfPageType1
                 --page1.jspx
              --jsfPageType2
                 --page2.jspx
  -target
  -pom.xml

And pom.xml's build snippet is as follows

<build>
    <sourceDirectory>${basedir}/src/main/java</sourceDirectory>
    <outputDirectory>${basedir}/target/${project.artifactId}/classes</outputDirectory>
    <resources>
      <resource>
        <directory>${basedir}/src/main/resources</directory>
        <excludes>
          <exclude>**/*.java</exclude>
        </excludes>
      </resource>
    </resources>
    <testResources>
      <testResource>
        <directory>${basedir}/src/test/resources</directory>
      </testResource>
    </testResources>
    <finalName>${project.artifactId}</finalName>
    <plugins>
      <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>${jdk.version}</source>
          <target>${jdk.version}</target>
          <optimize>true</optimize>
          <useProjectReferences>true</useProjectReferences>
        </configuration>
      </plugin>
      <plugin>
        <artifactId>maven-war-plugin</artifactId>
        <version>2.1.1</version>
        <configuration>
          <warSourceDirectory>${basedir}/src/main/webapp</warSourceDirectory>
          <webResources>
            <resource>
              <directory>${basedir}/src/main/resources</directory>
              <directory>${basedir}/src/main/resources/Images</directory>
            </resource>
          </webResources>
        </configuration>
      </plugin>
    </plugins>
  </build>

and MyProject.war's dir structure look like

     MyProject.war

              --Images
                 ---OtherImages
              --Css
              --Meta-INF
              --login.jspx
              --jsfPageType1
                 --page1.jspx
              --jsfPageType2
                 --page2.jspx
               --WEB-INF
                  --classes
                       ---applicationContext.xml
                       ---com(classes package)
                       ---Images
                          ----myImage.png
                  --lib
                  --web.xml
                  --faces-config.xml

In MyClass i am trying to access image

1st Try

private static String PATH_TITLE_IMAGE = "src/main/resources/Images/myImage.png";
com.itextpdf.text.Image bckGrndImage = com.itextpdf.text.Image.getInstance(PATH_TITLE_PAGE_IMAGE);   

2nd Try

private static String PATH_TITLE_IMAGE = "src/main/webapp/Images/myImage.png";
    com.itextpdf.text.Image bckGrndImage = com.itextpdf.text.Image.getInstance(PATH_TITLE_PAGE_IMAGE);

as oers Said i should use

MyClass.class.getResource("/images/image.jpg")

after adding suggested solution (but it still dont work)

    private static String PATH_TITLE_IMAGE = "Images/myImage.png";
URL url =  MyClass.class.getResource(PATH_TITLE_IMAGE);
com.itextpdf.text.Image bckGrndImage = com.itextpdf.text.Image.getInstance(url);  

Thanks in advance

The default resource directory for all Maven projects is src/main/resources which will end up in target/classes and in WEB-INF/classes in the WAR. The directory structure will be preserved in the process.

.
 |-- pom.xml
 `-- src
     `-- main
         |-- java
         |   `-- com
         |       `-- example
         |           `-- projects
         |               `-- SampleAction.java
         |-- resources
         |   `-- images
         |       `-- sampleimage.jpg
         `-- webapp
             |-- WEB-INF
             |   `-- web.xml
             |-- index.jsp
             `-- jsp
                 `-- websource.jsp

The suggested way to put your resources is in the src/main/resources
