MappingTool : Java class and Ant task
Hi,
There is 2 ways to use the same MappingTool : as a Java class or as an Ant task.
http://openjpa.apache.org/builds/2.1.0/apache-openjpa-2.1.0/docs/manual/manual.html#ref_guide_integration_mappingtool
http://openjpa.apache.org/builds/2.1.0/apache-openjpa-2.1.0/docs/manual/manual.html#ref_guide_mapping_mappingtool
It look like the same but it is not, at least on syntax point of view :
On command line according to the doc : -schemaAction build
On ant task : <mappingtool action="buildSchema"
On reality from my experience for command line : ... -action buildSchema
Currently, I manage to make it work but I'd like to add more parameters like -dropTables true.
What would be the Ant task syntax for it ?
What would be the recommended way to use it ?

Good guess and thanks for the clarification !

Hi Jean-Baptiste,
The Mapping Tool has two separate "action" parameters: -schemaAction and
-action.
-schemaAction build should be similar to the SchemaTool usage:
-
build: Generate SQL to build a schema matching the one in the given XML
file. Unlike add, this option does not take into account the fact that
part of the schema defined in the XML file might already exist in the
database. Therefore, this action is typically used in conjunction with the
-file flag to write a SQL script. This script can later be used to
recreate the schema in the XML
-action buildSchema is more commonly used and I believe is the action you
are really looking for:
- buildSchema: This is the default action. It makes the database schema
match your existing mappings. If your provided mappings conflict with your
class definitions, OpenJPA will fail with an informative exception.
Since the Mapping Tool already provides the ability to drop tables:
- -dropTables/-dt <true/t | false/f>: Corresponds to the same-named
option on the schema tool.
Since all of the MappingTool parameters should be accessible from the ant
task, the corresponding ant task invocation should be similar to this
(although I have not personally tried it):
<mappingtool dropTables="true" action="buildSchema">
<fileset dir=".">
<include name="**/*.java" />
</fileset>
</mappingtool>
Make sense? I don't use Ant, so I don't know for sure that this all works,
but according to our docs, it should... :-)
Good luck,
Kevin
