Tag Handlers for Basic Tags

The handler for a basic tag without a body must implement the doTag method of the SimpleTag interface. The doTag method is invoked when the end element of the tag is encountered.

The basic tag discussed in the first section, <tt:basic />, would be implemented by the following tag handler:

public HelloWorldSimpleTag extends SimpleTagSupport {
    public void doTag() throws JspException, IOException {
        getJspContext().getOut().write("Hello, world.");
    }
}
