jRelationalFramework / News: Recent posts

The jRelationalFramework is a java-to-relational mapping tool that is generic enough to work for most any project and relational database, simple enough to be easy to learn and use, yet flexible enough to handle complexity when needed.

The first official beta release of jRelationalFramework 2.0 is now available. The 1.x codebase has been largely refactored and many new features added for greater efficiency and flexibility.... read more

- Added com.is.jrf.MySQLDatabasePolicy. Thanks to David Marshall. David has documented where the tests fail due to MySQL issues in the Readme-MySQL.txt file.
- Added com.is.jrf.BigDecimalSpec, com.is.jrf.SQLDateColumnSpec, and com.is.jrf.StringArrayColumnSpec. Thanks to Alix Jermyn at IconMediaLab in Belgium.
- Added an example using the VideoStore code inside of EJB. See examples/ejb at the root of the distribution.
- Removed the requirement to use a properties file. A warning message will be printed that it can't be found, but it won't fail anymore unless the JDBCHelper and the DatabasePolicy is not set properly by the application code.
- Made some changes to the way transactions are managed to better work with the XA data source spec.
- Renamed the package names for log4j now that it is an Apache Jakarta tool.

New features in JRF release 1.5

- JDBCHelper pooling (and hence connection pooling) capability.
- Now logging with Log4j (http://www.log4j.org) instead of our home-grown LogWriter.
- Added FloatColumnSpec and LongColumnSpec objects.
- Updated the documentation to explain JDBCHelperPool and the new logging mechanism.

This release has a code generator for AbstractDomain and PersistentObject subclasses using the JDBC metadata information. Other minor changes.

Thanks to Ralph Schaer there is a code generator that will be released within the next week. This will generate AbstractDomain and PersistentObject subclasses based on an existing database.

There was a problem on Oracle with the 1.3 code changes that is fixed in this release. There is also a better ResultPageIterator class in this "bug-fix" release.

This release has additional support for optimistic locking using numeric columns and adds a new domain superclass for performance gains. <p><a href="http://sourceforge.net/project/shownotes.php?release_id=10227">

The latest release has support for HypersonicSQL as well as support for deep joins. Check the change notes for more details.

This release improves on the database-independence of the test cases with the addition of a new CreateTableSQLGenerator class. This release also improves configurability via a properties file.

The first public release of the jRelationalFramework is now available. Thank you to the is.com management for their support of this project!
