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
