I'm trying to create a new entity bean for an existing application. When I deploy I get the following error:
anonymous wrote : org.jboss.deployment.DeploymentException: Field changeDate in prim-key-class must be of the same type.
New table sql
CREATE TABLE `projecthistory` (
| `ProjectId` int(11) NOT NULL default '0',
| `ChangeDate` datetime NOT NULL,
| `UserID` varchar(50) NOT NULL,
| `Status` int(11) NOT NULL default '0',
| PRIMARY KEY (`ProjectId`, `ChangeDate`),
| KEY `projecthistory_ProjectID_FK` (`ProjectId`),
| CONSTRAINT `projecthistory_ProjectID_FK` FOREIGN KEY (`ProjectId`) REFERENCES `projects` (`ID`) ON DELETE CASCADE ON UPDATE CASCADE
| );
prim-key in ejb-jar.xml
<prim-key-class>lingonet.projecthistory.ProjectHistoryKey</prim-key-class>
The key class
public class ProjectHistoryKey {
| public Integer projectID;
| public Date changeDate;
|
| public ProjectHistoryKey (Integer projectID, Date changeDate) {
| this.projectID = projectID;
| this.changeDate = changeDate;
| }
| }
|
I am using java.util.date in my java code, which works for other beans where the date isn't a primary key? Do I need to use java.sql.date or is there just a problem using dates in primary keys or something else entirely? Some guidance here would be appreciated.
Mike
