How to open a properties file from another package on Netbeans (JAVA)

Question

I have a bean that needs to take some parameters from a properties file but I can not find it (java.lang.NullPointerException) in order to open it. My bean is in the extra.beans package while the properties file is in the extra.dao package. I am trying to do

file = new FileInputStream("database.properties");
prop.load(file);

and I have tried any possible combination for the path but I can not find it. I am using Netbeans 7.4. How can I open it?

Answer 1

You can Use Resource Bundle for that.

ResourceBundle resBundle =  ResourceBundle.getBundle("PropertyFileName");  // without extention 
String name=  resBundle.getString("Required Attribute");  // example username

Answer 2

Specify the full path. It should work.

Answer 3

If you're loading the properties file into a Properties object, try the something like:

Properties properties = new Properties();
properties.load(getClass().getResourceAsStream("../dao/database.properties"));

I don't know your full package structure but using this approach and putting the full path to the properties file would also work, ie: /extra/dao/database.properties

Answer 4

file = getClass().getClassLoader().getResourceAsStream("extra/dao/database.properties") ;
prop.load(file);
