<para>One of the view technologies you can use with the Spring Framework

is Java Server Pages (JSPs). To help you implement views using Java Server Pages
|

the Spring Framework provides you with some tags for evaluating errors, setting

themes and outputting internationalized messages.</para>

<para>Please note that the various tags generated by this form tag library

are compliant with the <ulink url="http://www.w3.org/TR/xhtml1/">XHTML-1.0-Strict specification</ulink> and attendant <ulink url="http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_XHTML-1.0-Strict">DTD</ulink>.</para>

<para>A MessageSourceResolvable argument (direct or through JSP EL).
|
|
Fits nicely when used in conjunction with Spring's own validation error
|
|
classes which all implement the MessageSourceResolvable interface. For
|
|
example, this allows you to iterate over all of the errors in a form,
|
|
passing each error (using a runtime expression) as the value of this
|
|
'message' attribute, thus effecting the easy display of such error
|
|
messages.</para>
