Using Logging in MSP

- Use logger instead of system.out.println statement
- Use FINE,FINER,FINEST level for logging in sensitive places, for instance in a loop. To improve performance: do something like:

if (logger.isLoggable(Level.FINEST) {
//log at finest level
logger.finest("test");
}

- In catch blocks, always join the exception trace in the log, it makes the life easier when debugging: so use

try {
some code
} catch(Exception e) {
logger.log(Level.SEVERE, "some message", e);
}

Persist data easily

If you need to save data in a database, you might need to use technologies such as JDBC, Hibernate...
Hence, the complexities of those tools are sometime not worth for the needs of persistence.
I found a framework to persist Java beans and manage persistent data easily:
DB40 : http://www.db4o.com
Developer area: http://developer.db4o.com

ObjectContainer db=Db4o.openFile("database.db");
   try {
       Data test1 = new Data("Sebastien",26);

       //persist test1 object
       db.set(test1);

       }
   finally {
       db.close();
   }
