Since I am only able to pass simple beans around using my Web Service
framework, I wonder how to incorporate business logic around these beans.

My idea was to let my Beans be the base class and simply extend these
with more sophisticated classes with the nessesary business logic
inside. However, when I do a cast from MyObjectBean to MyObject I get a
ClassCastException. Is it not possible to cast in this direction?

public class MyObjectBean
{
    publc MyObjectBean(){}
    private String strMember;

    public setStrMemeber(String str)
    {
        strMember = str;
    }

    public getStrMemeber()
    {
        return strMember;
    }
}

public class MyObject extends MyObjectBean
{
    public void print()
    {
        System.out.println(this.getStrMember());
    }
}

...
MyObjectBean myobjectbean = new MyObjectBean();
MyObject mo = ( (MyObject)myobjectbean ).print(); << ClassCastException
...

Thanks in advance,
Casper
