Can not do class diagram to java code generate with annotation

Hi,

We want to generate java code from the class diagram which has annotation.

For example:
I make a simple class diagram Class1 with an attribute a1.I add an annotation on this attribute.

when I generate java code(has annotation) from the class diagram,the code followed:

public class Class1 {

private string a1;

}

But I want the results:

public class Class1 {
/**
* something important!!!
*/
private string a1;

}

How to generate the annotations in java code? Please let us know.

Thanks and Regards
Tang
