is there a specific way to write sql queries in entity beans in ejb spec 3
rather than normal sql query?
i have defined namedquery as follow.
@NamedQueries( [EMAIL PROTECTED](name = "Language.findByAgentCode",
query = "SELECT l FROM Language l WHERE l.AgentCode =
:agentcode")})
but when deploying following exception is thrown
2007-11-28 10:03:31,237 WARN [org.jboss.system.ServiceController] Problem
starting service persistence.units:ear=sdb.ear,jar=sdb3.jar,unitName=Language
