Hi all,
I have cleard SCJP 1.4 with 85%. And want to give scwcd1.5. But i donno
how to start preparation .Servlet and basics of JSP are ok for me.
But when it comes to tag libraries i ll go mad. Every time my efforts of giving SCWCD stops in tag library.

Atleast recommend me some material where i can easily understand tag libs.

Thanks in advance... and congratulations to all who have passed the SCWCD ..

I learned tag libs and tag files by coding as many examples as I could think of. This was a real big help in my passing the exam.

I agree with both Deepti and Michael.

The HFSJ chapters on custom tags is about as good as I have seen (or created; I was a course developer for Sun in a previous life).

But nothing compares with learning from experience. I would recommend coding a simple loop custom tag from scratch. For example, have you ever needed to loop over the values of an enumerated type? (to populate the <option>s of a <select> tag for example?)

Imagine your webapp includes an enum of hobbies:


And you want a JSP form to ask the user select their hobbies. You could do this using scriptlet code like this:


Buut as we know "scriptlets are bad, ngKay" (a'la Mr. Garison from South Park).

So a better solution is to use a custom tag:


Your mission --if you choose to accept it-- is to develop the forEnum tag. The easiest solution will be to develop a "Simple Tag" handler. Start there, but when you get that done create a second implementation using a "Classic Tag" handler. When you get that created you will know 80% of what you will need for the SCWCD exam. Note: a "Tag File" is not an appropriate technology for this exercise.

Good luck on your mission and if you need assistance feel free to email me at b_basham@yahoo.com

Regards,
Bryan
