This has workied for me. I had to separate java.sql.Date and java.sql.Time, and the following works for mr. <query> | <query-method> | <method-name>findByTimeInterval</method-name> | <method-params> | <method-param>java.sql.Time</method-param> | <method-param>java.sql.Time</method-param> | </method-params> | </query-method> | <ejb-ql> | <![CDATA[ | SELECT OBJECT(time) | FROM TimeEJB AS time | WHERE time.time1 > ?1 | AND nonWorkingDay.endTime < ?2 | ]]> | </ejb-ql> | </query> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964420#...
