Thanks, Kevin. I'll open a JIRA issue. I guess there's a similar issue with the configuration flag "-schemas" for Reverse Mapping Ant Task. The documentation (Part 3, chapter 14, paragraph 1.5) says that "the task's parameters correspond exactly to the long versions of the command-line arguments to the org.apache.openjpa.jdbc.meta.ReverseMappingTool". Don't know, if it goes with the command line call, probably it does, but if I run the Ant task I get the error message "reversemappingtool doesn't support the "schemas" attribute". I checked the source code of org.apache.openjpa.jdbc.ant.ReverseMappingToolTask, this attribute is not listed in the javadoc.
Kind regards, Michael. > -----Ursprüngliche Nachricht----- > Von: Kevin Sutter [mailto:kwsut...@gmail.com] > Gesendet: Mittwoch, 14.
