Re: Understanding Object Usage

Ah.. ...that makes sense for the ConnectionBean. I have done refactoring
before, I'm just always paranoid that it misses something. I guess it's time
to start trusting it. ;-)

I agree with the JSP thing. I some times put Java code in the JSP and I hate
doing every time. I just wrote my first simple JSF page and I can see where
this would be very powerful. And yes, my problem was putting it into
production. Luckly it's a small shop and that's basically how I learned all
my programming is by writing various programs there.

Probably a question for a different post, but hand code vs. WYSIWYG for JSF
and Swing UI's? I have done both, but I see conflicting information all the
time about this.

I do have a ConnectionBean I have created. It works in conjunction with a

Just refactor it, if you need to. If you do not know how, put the
cursor on the identifier "ConnectionBean" and right-click, Refactor,
Rename. This will rename the class, i.e. the java file, and all the
places in the source where it is used.

A better name might be "FooBarConnection" where FooBar is the _system_
you need to connect to, not the machine or the operating system. This
will also make it clearer in your mind what actually belongs in the class.

I just wanted to make sure to get all my ducks in a row before I start
deploying a bunch of Java stuff. When learning how to write JSP's I made
quite a mess at the last place I worked on an intranet site so I really

want

to avoid that again. I would be embarrased for anyone to actually see

some

of that code.

I believe that the reason JSP's are hard to write well, is the fact that
you mix two languages - one for presentation and one for business logic
- and that it is extremely easy to blend the two together, and THEN you
have the mess.

I have found that it creates a reasonable code base to use taglibs only
in JSP pages (hence move the presentation stuff in CSS), and use
JavaServer Faces to do the work. It is however a bit uphill to get
working properly.

(and your basic problem was you put your initial prototype in production
;-) )

Thank you all for your comments and suggestions. I'm glad to know for the
most part I wasn't too far off in my though pattern with this.

You are most welcome. Learning new programming paradigms is not easy
on your own.
