How to use properties file

Question

Hi,
I want to use properties file in my application. I have kept properties file inside a directory called properties which is inside myProject(which is the parent directory of my project) i.e "myProject/properties".
My java file where i want to call this properties file is inside the myProject/WEB-INF/src/java.
How can i call the properties file from myProject/WEB-INF/src/java/PropertyReader.java
I wrote java program in myProject/WEB-INF/src/java/PropertyReader.java like:::::
ResourceBundle resBun = ResourceBundle.getBundle("Test", Locale.getDefault()); // Test.properties is inside myProject/properties
resBun..getString("name");
After running the program i am getting the following errors:::::
Exception in thread "main" java.util.MissingResourceException: Can't find bundle for base name Test, locale en_US
at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:836)
at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:805)
at java.util.ResourceBundle.getBundle(ResourceBundle.java:576)
at PropertiesReader.main(PropertiesReader.java:4)
What is the issue? How to use properties file?
Waiting for reply.
Thanks

Still getting same exception. As you explained i tried like the below:::
1. I am using ant as build tool.
2. My properties file is for database configuration
My properties file is::
database.properties (inside myProject/properties)
JDBCDriver=org.gjt.mm.mysql.Driver
JDBCConnectionURL=jdbc:mysql://pmdbmysql:3306/bandwidthshaper?user=admin&password=admin
My java package structure is
WEB-INF/src/java
WEB-INF/src/classes
For build WEB-INF is the base directory and build.xml is inside the src directory
In my build.xml i wrote the following lines for compilation::
          <target name="compile" >
               <javac srcdir="src" destdir="src/classes" debug="true" debuglevel="lines,vars,source">
                    <classpath refid="class.path"/>
               </javac>
<copy todir = "src/classes" >
<fileset dir = "../properties" />
</copy>
               <jar jarfile="lib/${project.jar.file}" basedir="src/classes"/>
          </target>
I am copying properties file to the classes directory.
Now in java file which is inside /WEB-INF/src/java, I wrote::
try {
Properties programProps = new Properties();
InputStream is = getClass().getResourceAsStream("/database.properties");
if(is == null)
throw new IllegalStateException("Properties file missing ");
programProps.load(is);
System.out.println("driver name::::::: "+programProps.getProperty("JDBCDriver"));
is.close();
} catch(Exception e) {
e.printStackTrace();
After compilation in my classes directory i am getting database.properties file and my java file with package.
At the time of running i am getting "java.lang.IllegalStateException: Properties file missing"
Now tell me where is the fault. Why again i am getting exception.
Thanks
