Hi All, Newbie trying to experiment with JPA2 (openjpa - TomEE). I would appreciate any pointers on where I might be going wrong with the example below ....
I can read data from my Persistence-unit, but cannot write data (and no error is generated) and I cannot see any generated SQL The only log output I get is as follows: ============================= 25019 PRSX TRACE [http-bio-8080-exec-5] openjpa.jdbc.SQL - <t 25544092, conn 20981618> executing prepstmnt 19451103 SELECT t0.bidEndDate, t0.bidStartDate, t0.createdDate, t0.initialPrice, t0.name FROM item t0 WHERE t0.id = ?
