Struts 2 and WebWork: Validator XML Syntax Trivia
I had to write a validator to check if a date entered in a form is not one in the future. I could not find an example of this in the documentation, and had to search around a bit to figure out the right XML syntax.
<validators> <field name="someDate"> <field-validator type="fieldexpression"> <param name="expression"><![CDATA[!someDate.isAfter(@com.domainlanguage.timeutil.Clock@today())]]></param> <message>Please enter a date on or before today</message> </field-validator> </field> </validators>
Notice the ‘@’s. Posting this here for anyone who might find it helpful. :-)
