I have defined a bean that has a property (among others) called userTS of type java.sql.Date.



I have a jsp that contains a maintenance form. When the page loads, it invokes to grab the elements of the previous form submit and populate the bean with them.



I have a hidden element in the form corresponding to the userTS property (which is not an editable element) and have ensured that it is in the appropriate yyyy-mm-dd format.



I have an overloaded setter method called setUserTS, one form of which accepts a String and converts it to a java.sql.Date by means of a valueOf call, and another that accepts a java.sql.Date directly.

When the form is submitted, my hidden element code...


<%=ts%>' >


... causes an "org.apache.jasper.JasperException: argument type mismatch" exception (under Tomcat).



I'm sure I'm making some kind of stupid basic error, but I have as yet proven too thick to find it. Any ideas?
