Hi there Xdoclet users,
I have a question regarding value objects and the reetrant issue. I know it has
been talked about a lot and I have scoured the archives for a solution, but my
problem still exists...
I am using weblogic8.1 and container mananged persistence. I am developing a
timesheet application. Anyway, I have a 1:n relationship between a timesheet
and a shift. Implemented as follows:
/**
* @ejb.relation
* name="Timesheet-Shift"
* role-name="timesheet-has-shifts"
* @weblogic.target-column-map
* foreign-key-column="C_TIMESHEET_ID"
* key-column="C_TIMESHEET_ID"
* @ejb.interface-method
* view-type="local"
* @ejb.value-object
* compose="au.gov.qld.des.aftimesheet.dto.ShiftTransferObject"
* compose-name="Shift"
* members="au.gov.qld.des.aftimesheet.ejb.ShiftLocal"
* members-name="Shift"
* relation="external"
* type="java.util.Collection"
*/
public abstract java.util.Collection getShifts();
/**
* @ejb.interface-method view-type="local"
*/
public abstract void setShifts(java.util.Collection shifts);
I am creating two timesheet value objects, one which is a
"TimesheetLightTransferObject" and does not include this relationship as a
strategy to avoid the reentrant problem.
The Shift bean on the N side of the relationship has it's relationship defined
as follows:
/**
* @ejb.relation name="Timesheet-Shift"
* role-name="shift-belongs-to-timesheet"
* @ejb.value-object
* aggregate="au.gov.qld.des.aftimesheet.dto.TimesheetLightTransferObject"
* aggregate-name="Timesheet"
* relation="external"
* @weblogic.column-map
* foreign-key-column="C_TIMESHEET_ID"
* key-column="C_TIMESHEET_ID"
*/
public abstract TimesheetLocal getTimesheet();
public abstract void setTimesheet(TimesheetLocal timesheetLocal);
Please note that the "setTimesheet" method has no @ejb.interface, but is still
showing up in the generated value object??
However, having done all this weblogic is still chucking a fit (ie,
ReentrantException), whenever I try to uupdate a timesheet through the local
interface from my session bean. I have scoured mailing lists and sites for the
last 2 days to no avail. Any assistance would be greatly appreciated.
Cheers,
Matt.
