Form taglib ver. 1.5

    Custom JSP taglib. Provides a JSP based replacement for standard HTML <form> tag with several useful enhancements. Also this taglib serves as an ancestor for other GUI-related tags from Coldtags suite like submission protection and client based validation.

For example:

<%@ taglib uri="taglib.tld" prefix="html" %>

<html:form method="post" action="http://host/cgi-bin/script">

Tag form automatically encodes URL in action in order to support URL-rewriting.

Body tag parameter lets you add parameters for your form (hidden fields):

<html:form method="post" action="http://host/cgi-bin/script">
   <html:parameter name="var1">value for var1</html:parameter>
   <input type=text name=User>

Also you may modify your existing forms to some MVC framework. Body tag controller lets you describe a real target URL for actions. In this case value for action field will be passed as a parameter for request. For example:

<html:form method="post" action="http://host/cgi-bin/script">
   <html:controller name="oldURL">http://host/servlet/OneEntry</html:controller>

Here data will be actually posted to http://host/servlet/OneEntry and value for action field (http://host/cgi-bin/script) will be passed as a parameter oldURL. So with the very limited changes (replace old form tag with html:form and add controller) you may convert existing web application into MVC-based stuff.

Also you can automatically set target to the hidden iframe (attribute iframe). It lets you easily implement remote scripting with forms.
