OK, I'll try to paste some of the entity objetcs code to this thread.
Check out the Company and BranchPO below. All getter and setters omitted.
We're using a webservice to fill-out CompanyPO with information. Som companies
have more then 700 branches, which all are aded to the branches collection of
CompanyPO.
After finishing the company with all the branches, address etc. the company
entity is persisted, if all rules is passed.
The persists operation completes succesfully after about half a secondf, but
when we then are doing a flush operation on the entitymanager the container
will hang and after a while a timeout is thrown.
Maybe a solution is to perstist and flush more often, which shouldn't be
neccesary with the relative small data amount. But, I'll give it try anyway.
If you need more information please tell me which.
