Storing configuration related information in Java

Question

I am working on the Java desktop application using Swing. As the application is data centric, I am using the JDBC for connection with mySql. I would like to store database connection (connectionString), username and password in the seperate file. What will be the best approach for this?

(In .net app.config store these informations)

the property files will work fine for read and write operation — clevertension, Mar 09 '12 at 06:47

You can store the parameters in a properties file like

hostname=localhost:3306/mydb
username=root
password=pass

Store this information in a properties file like say config.properties. You can load the properties in java during runtime using the Properties class in java

Properties prop = new Properties();
prop.load(new FileInputStream("config.properties"));
String connectionString = prop.getProperty("hostname")
String username = prop.getProperty("username")
String password = prop.getProperty("password")

You can use a properties file for that. Hibernate has already its properties configuration file. You can also use hibernate.cfg.xml.
