[jira] Commented: (OJB-112) Tool for forward engineering from
repository.xml
[ http://issues.apache.org/jira/browse/OJB-112?page=comments#action_12426900 ]

----------------------------------
Hi Tom,
now the forward engineering tool works nearly perfect.
I found only one specific test mapping (based on a test posted by a user) in OJB-test-suite that cause problems. It's a "one-side" m:n mapping, the n-side object doesn't list the m-side objects, thus in the mapping only one class-descriptor declare the m:n-collection-descriptor. In this case the forward tool only create an indirection table with all m-side FK entries and completely ignore the n-side FK entries. With the attached test repository (repository_test.xml) you can reproduce the issue. Don't ask me if this specific use cause makes any sense, but it would be great if the tool can handle this.
Additionally I start writing a forward engineering howto (section about the 'forward' ant task is completed - in bad English ;-)). It would be great if you find time to write a few words about how to use your tool, requirements, pitfalls. No need to respect the Apache-Forrest notation simply write the text and send it to me.

> Currently there are no tools which support forward generation from OJB's repository.xml. Such a tool should read in the metadata mappings and generate the Java bean source code as well as SQL schema. The SQL schema can be generated in Torque format so that DDLUtils can generate the DB specific schema.
