Java.lang.NullPointerException in the code to read a properties file

Question

I have written the following code to read a properties file...........
<b>
public Property(String fileName)
    try
       InputStream is = MyClassName.class.getClass().getClassLoader().getResourceAsStream(fileName);     
       prop.load(is);
       is.close();
    catch (Exception ex)
        System.out.println("The Exception is:        " + ex.getMessage());
        ex.printStackTrace();
</b>
But this code is giving <b> java.lang.NullPointerException </b> at <b> prop.load(is) </b>
please help me....

hi,
    If you are loading a resource (property) file from a jar file you can use
getResourceAsStream("com/test/test.properties").
    if the propery file is in outside of your jar file . you can use
Property portalProps = new Property ();
try {
               FileInputStream fileInputStream = new FileInputStream("<FilePath + FileName>");
               portalProps.load(fileInputStream);
               fileInputStream.close();
          } catch (IOException e) {
               //Log the error
