hi jacek, thanks for your help, i did change my birthdate field to sql.Date now. the error message remains. but i realized, that the error message just appears at the first write operation: all following write operations are executed successfully. i will try to make my tests, i think i'll just ignore the first write action and start my tests from the 2nd write operation on.
for the moment, thanks! mario. 2008/7/6 Jacek Laskowski <[EMAIL PROTECTED]>: > On Sun, Jul 6, 2008 at 11:34 AM, Mario Kofler <[EMAIL PROTECTED]> wrote: >> > > Hi Mario, > > Let's make it simpler by removing some unneeded, defaulted > configuration values in your sample. > >> <persistence xmlns="http://java.sun.com/xml/ns/persistence"; >> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; >> >> xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"; >> version="1.0"> >> <persistence-unit name="valhalla" transaction-type="JTA"> > > Hint: you may remove transaction-type as it's JTA in managed > environment like Geronimo. > >> <description>videothek</description> >> >> <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> > > Provider defaults to openjpa in Geronimo.
