How to use CompositeData for mbean operations

Question

Hi all,
I am trying to register a mbean whose operations have a composite data type interface something like below, any ideas how to achieve this?
/**MXBean**/
public interface someXXXXxxxMXBean {
    public ReturnCompositeDataInterface doSomething(ParamCompositeDataTypeInterface param1);
/**ReturnCompositeDataInterface **/
public interface ReturnCompositeDataInterface {
    public String getString();
    public double getDouble();
    public TimeStamp getTimeStamp();    
/**ParamCompositeDataTypeInterface **/
public interface ParamCompositeDataTypeInterface {
    public String getString();
    public int getInt();
    public Date getDate();    
}thanks in advance.

Krish,
This should just work. The only potential source of problems that I see is the TimeStamp class, depending on how that is defined. But if its definition doesn't match the MXBean rules, you should get an exception message explaining what's wrong.
