Hi lisandrodc, please carefully read all documents
http://code.google.com/appengine/docs/java/datastore/ and http://www.datanucleus.org/products/accessplatform_1_1/guides/jdo/daolayer_design.html Also many people cannot read spanish, if you would write in english you may get more answers. I think you problem is that you datastore operation failed in catch block and since you are closing persistence manager first and then rollbacking it fails. Solution: 1) read everything as carefully as possible, look at example and try experiment. 2) in finally block rollback first and then close persistence manager On Jul 18, 11:01 pm, lisandrodc <lisandr...@gmail.com> wrote: > Hi!
