Recently I got a weird error with the SQL tag of JSTL. We are using JSTL for simple database table maintenance and it worked fine before. I don't know what is changed but now we got sql error ORA-17004 (Invalid column type) every time when user tries to insert a new record. However, if all the form fields are filled in, there will be no problem. Does anybody have similar experience before?
By the way, We are using <sql aram...> and <sql ateparam...> to pass the values to the Sql statement, but I checked several times of the values passed in and there should not be any problem.
