Making a Color Bar

• Let's make a simple application that uses attributes in JSP tags.
• The colorbar that you see at the top of this document can easlily be generated this way.  We can send the table border and the cell background colors as attributes.
• We define one JSP, a tld file, and three tag handlers.
•  ColorBar.jsp The JSP that will generate the color bar.
•  table.tld The tag library definition file, tells us where to find the tag handler classes (below).
•  BeginTable.java Writes the <table> and <tr> tag, and optionally assigns a border.
•  EndTable.java Writes the </tr> and </table> tags.
•  Row.java Writes the <td> tags, with an optional color attribute.
• We also need to add an entry to web.xml as well.
    <taglib>
        <taglib-uri>/tbl</taglib-uri>
        <taglib-location>table.tld</taglib-location>
    </taglib>
• And finally, the result:
