1. Preface:


The important points of writing programs are to make our code reusable, scalable and flexible.

JSP based on object-oriented Java technology, we can use the design patterns to make these features.

And the combination of JSP and XML allows us to encode a more choice, write sophisticated code is not a distant fairy tale.

Here we will talk about programming using our custom or applying other defined tag. and deploying Taglib.

To apply tag,

-------------Create a TLD file.

TLD (Tld:tag Library descriptor Tag Library descriptor) file, standard XML-formatted markup definition file.

Define tag and his various attributes and processing files, and so on.

-------------tag Handler (tag processor.)

is actually a Java class file, used to handle tag. Each tag tag required in the TLD file

Specifies which class file to use to process this tag.

-------------use tag in JSP

Can be used through JSP directives.

It may be a bit complicated to create taglib and write tag processing files. But when we need to reuse or add functionality

, you will find out what great things we have done! ^_-(hehe, a bit exaggerated)
