Troy:
If I read your message correctly, I posit that you may be a C++ programmer
originally,
as it appears you want multiple inheritance.
There is no multiple inheritance in Java except via interfaces. You could make
a
MyPage interface and a MyJSPage interface and a MySessionUtil interface which
declare the methods in each. Then create a MyPageImpl class, a
MyJSPageImpl class, and a MySessionUtilImpl class which implement the
interfaces.
Then have pg_MyPage implement MyPage, MyJSPage, MySessionUtil
private MyPage myPage = new MyPageImpl();
private MySessionUtil mySessionUtil = new MySessionUtilImpl();
... and then delegate all the calls:
public void someMyPageMethod() {
myPage.someMyPageMethod();
}

Subject: [ND] Superclassing problems
Hey all,
I was wondering if someone can help me out. I have been been creating my
own classes such as MYButton, MyPage etc..
What I am having trouble with though is trying to superclass 2 or more
modules.
i.e. I have 3 modules: MyPage, MyJSPage,MySessionUtil
Problem occurs when I want to give pg_MyPage the properties of 2 or more of
these modules.
I end up having to superclass pg_MyPage --> MySessionUtil which I must then
superclass to MyJSPage which is then superclassed to MyPage
This implementation works fine... but then I lose the ability to implement
only MySessionUtil or MyJsPage by themselves.
I know I have probably gone about this the wrong way and I would really
appreciate any suggestions.
Thanks,
Troy
