File templates - lower, upper, camel case

I have a few file templates to generate stub Java classes.

It works well but how can I use passed variable to make field definition?

For instance I pass MyClass as the param and in stub it's:

private MyClass myClass;

public MyClass getMyClass() {

     return myClass;

}

public void setMyClass(MyClass myClass) {

     this.myClass = myClass;

}

So the question is how to make camel case name from the class name in the template?
