The custom tag tag has many features, such as:
· You can customize the tag label properties in a JSP page
· Accessing all objects in a JSP page
· Can dynamically modify page output
· They can communicate with each other. You can create a JavaBeans component and then call this JavaBeans component in a tag and call it in another tag.
· Tag allows you to nest with each other, and you can perform some complex i
the tag library available for Web ApplicationsDeclare a tag Library
Before using any custom tag, add the taglib command to the page to declare that the JSP page will use the tag defined in the tag Library:
The URI attribute indicates the URI that uniquely identifies the tag library Descriptor (TLD). The URI is described in the tag library descriptor. This URI can be direct or non-direct. The prefix attribute defines the prefix between the tag def
describes how JSP pages use labels and describes different types of labels.
To use labels, the page creator must do the following two things:
· Declare a tag library containing labels
· Make the tag library implementation available for Web applications
Declaring tag libraries
By adding the TAGLIB directive to the page before using any custom labels, declaring the JSP page will use the label defined in the tag library:
The URI attribute represents a URI that uniquely identifies the tag lib

2 Find specific classes to implement these custom behaviors
The first requirement-find a custom behavior that belongs to that tag library-is done by the prefix of the label directive (Taglib directive ' s Prefix), so elements that use the same prefix on the same page belong to this tag library. Each tag library defines a default prefix that is used in a document in a tag library or in a page to insert a custom label. So, you can use prefixes other than those such
