The code generated when you add a new Bean property currently produces code 
like this:
private int foo;

public int getFoo() {
  return this.foo;
}

public void setFoo( int foo ) {
  this.foo = foo;
}

A number of developers use the convention that places an underscore in front of 
any private member variables.  The Bean pattern generator should be 
configurable to produce differen styles of code.  

The way I would have written the above getter/setter is:

private int _foo;

public int getFoo() {
  return _foo;
}
public void setFoo( int foo ) {
  _foo = foo;
}
