Hi Andreas,
thank you for your response.
I tried this. If I run the Ant task example from the OpenJPA manual for
creating a schema (Schema Tool Ant Task) then the system tells me:
[schematool] The options supplied to the SchemaToolTask are not valid.
Please check your ant build file.
If I try to run the mapping tool against the database I receive the
following:
[reversemappingtool] <openjpa-1.0.2-r420667:627158 fatal user error>
org.apache.openjpa.util.UserException: A JDBC Driver or DataSource class
name must be specified in the ConnectionDriverName property.
Below is my ant task:
Any idea what is wrong?
Thank you, Lars
