Description copied from class: TagLibraryValidator

Validate a JSP page. This will get invoked once per unique tag library URI in the XML view. This method will return null if the page is valid; otherwise the method should return an array of ValidationMessage objects. An array of length zero is also interpreted as no errors.

Overrides:

validate in class TagLibraryValidator

Parameters:

prefix - the first prefix with which the tag library is associated, in the XML view. Note that some tags may use a different prefix if the namespace is redefined.

uri - the tag library's unique identifier

page - the JspData page object

Returns:

A null object, or zero length array if no errors, an array of ValidationMessages otherwise.
