Hi all,
I am trying to go through the process of forward mapping using the
MappingTool. I am using a persistence.xml and an orm.xml to do this. An
org.apache.openjpa.util.MetaDataException exception is thrown each timne I
run the MappingTool though, please advise on what steps I can take to
remedy. I run it like this, using the '-schemaAction build':
java -cp
/home/vic/openmdx/dev/openmdx2/jre-1.6/core/lib/openmdx-base.jar:/home/vic/Downloads>
/apache-openjpa-2.2.1/src/java:/home/vic/Downloads/apache-openjpa-2.2.1/openjpa-2.2.1.jar:/home/vic/Downloads/apache-openjpa-2.2.1/openjpa-all-2.2.1.jar
org.apache.openjpa.jdbc.meta.MappingTool -p persistence.xml -schemaAction
build orm.xml
I get the following output for that, what I can not understand is that my
persistence metadata is contained inside the orm.xml file so there IS
metadata, (persistence.xml and orm.xml follow after the output log):
31 openjpa INFO [main] openjpa.jdbc.JDBC - Using dictionary class
"org.apache.openjpa.jdbc.sql.MySQLDictionary".
