The Bank Transformation Toolkit provides an extendable set of custom
JSP tags that make it easier to create JSPs by limiting the amount of Java™ coding
required to implement a JSP. The toolkit custom JSP tags are based on the
JSP Custom Tags defined in the JSP 1.1 specification. The toolkit uses a tag
library to describe the custom tags, their attributes, and their related Java classes
(beans). A tag library (a TLD file) is an XML document that externalizes the
tags. The toolkit uses the tags to instantiate JSPs based on the attributes
of the tags and then render the HTML to display the JSPs.
You use the toolkit
custom JSP tags in the same way you use any custom JSP tag that conforms to
the JSP 1.1 specification. (If you are using Rational® Application Developer to develop
JSPs, you can see a representation of the tags at design time. See Visual
custom tags.)
The JSP tags provided by the toolkit can be divided into
the following categories:
- Simple components. These are a set of classes responsible for rendering
the HTML contents based on the attributes of the tag and the dynamic information
obtained from the context for the associated data name. These classes are
stateless (no data from the session is needed). Following are the simple components:
Containers. The following tags are containers for the simple components
listed above:
Control tags. These tags provide the functionality needed for
submitting the required hidden fields to the client. This is done to get them
back to the server side when the user performs a submit action in the rendered
page. FormTag is also a container. Following are the control tags:
