RE: OJB Deadlock due to reference descriptor
Hi, OJB detects circular references and stops traversing if it detects an object already instantiated, it uses a cache for that.

Re: OJB Deadlock due to reference descriptor
OJB fully supports mapping of several classes to the same table. In this case, you'll read the same data into two data structures being kind of reflections of each other. -- Ilkka SUMIT JAIN wrote: I am using OJB with java 1.5 I have done the following mapping class-descriptor class=applications.dts.models.testcase.testcasegrid.TestCaseGrid table=dts.testcaseactions field-descriptor name=testCaseActionId column=TestCaseActionID primarykey=true autoincrement=true access=readonly / field-descriptor name=testCaseId column=TestCaseID / field-descriptor name=affectedInsert column=InsertFlag / reference-descriptor name=actionRef class-ref=applications.dts.models.testcase.testcasegrid.testcaseactions.TCAction auto-retrieve=true auto-update=true auto-delete=true foreignkey field-ref=testCaseActionId/ /reference-descriptor /class-descriptor class-descriptor class=applications.dts.models.testcase.testcasegrid.testcaseactions.TCAction table=dts.actions field-descriptor name=testCaseActionId column=TestCaseActionID primarykey=true autoincrement=true access=readonly / field-descriptor name=testCaseId column=TestCaseID access=readonly/ reference-descriptor name=testCaseGrid class-ref=applications.dts.models.testcase.testcasegrid.TestCaseGrid auto-retrieve=true auto-update=true auto-delete=true foreignkey field-ref=testCaseActionId/ /reference-descriptor /class-descriptor Logically it should be a deadlock but OJB does not throw any exception and is working fine.

Re: OJB Deadlock due to reference descriptor
Oops, the tables are not the same, so Roger's reply gives a better answer. -- Ilkka Ilkka Priha wrote: OJB fully supports mapping of several classes to the same table.
