Spring Roo JSPX and form tag

I am trying to use the form tag within a Spring Roo JSPX file: But everytime I run the application, I keep getting the following exception:

The prefix "form" for element "form:form" is not bound.

I have the form tag library included (xmlns:form="http://www.springframework.org/tags/form"). Can anyone help me get started on troubleshoot this error message? T开发者_如何学Gohanks!

A good start is to check maven repositories, dependencies and its versions in pom.xml file.

In XML files every tag has to be bounded with a closing tag. For Example has to be closed with tag. Usually in html files you don't need to close link tags, but in Spring and other xml formats like jspx, you have to close these tags.
