Kodo 3.0.0 beta now available

All,
Kodo JDO 3.0.0 beta 1 is now available at:
http://solarmetric.com/Software/beta/3.0.0/
Kodo JDO 3.0.0 is a major release, and contains significant changes to
properties, mapping information, and Kodo-specific APIs. To read more about
these, and to read about how to convert a Kodo 2 project to Kodo 3, see the
migration documentation at:
http://solarmetric.com/Software/beta/3.0.0/b1-docs/docs/kodo2.html
NOTE: the conversion is non-trivial, so we have provided a number of tools
to automate most of the process. So please read and obey the migration
documentation, which will guide you through the migration tool process.
For details about some of the major new features in this release, please
read the release notes at:
http://solarmetric.com/Software/beta/3.0.0/b1-docs/docs/relnotes.html
The full documentation is available online at:
http://solarmetric.com/Software/beta/3.0.0/b1-docs/docs/index.html
Some of the major new features include:
* New mapping system, providing more powerful and flexible mapping options.
* More configuration options for connection pooling.
* Configurable eager fetching of 1-1, 1-many and many-many relations.
Potentially reduces the number of database queries required when iterating
through an extent or query result and accessing relation fields of each
instance.
* More optimized SQL batching.
* Simplified package structure for Kodo-specific APIs.
Known issues:
* DB2, Informix, and Sybase do not fully pass our internal tests yet. Sybase
is close to passing, and DB2 and Informix probably work in many situations
as well, but they are not yet officially supported by this release.
* We have done only limited integration testing with application servers.
* Our IDE integration components are not included in this release.
As usual, please discuss any issues, desires, etc. on the beta newsgroup:

1. I can't see any standalone GUI tool to do mapping tasks, as you have
ever announced.The GUI will have its own beta program and release schedule.
2. the file : <kodo3.0>/samples/jsp/build.xml has a line wrong:

Kodo 3.1.0 Final Now Available

All,
Kodo 3.1.0 is now available! Get your copy while supplies last at
http://www.solarmetric.com/Software/Evaluate/ !
This is a significant new release with much enhanced functionality.
Highlights of 3.1.0 include:
- Added the ability to use Kodo from remote client machines communicating
with a persistence manager server.
- Kodo now supports the "horizontal" O/R inheritance model, where each leaf
of the inheritance hierarchy is mapped to a separate table.
- Sigificantly improved technology preview of Kodo Management / Monitoring
capability based on JMX.
- Added an abstract store manager, which is a building block for allowing
you to add support for non-relational data stores that Kodo does not
support. Includes an example using XML.
- Made major improvements to the Kodo Development Workbench, including more
powerful visualization and editing of mapping information.
- Added object locking APIs to the KodoPersistenceManager for fine-graned
control over object locking.
- Added custom lock group support, allowing field-level optimistic locking
granularity.
- Made many improvements to the Eclipse plugin.
- Made numerous performance optimizations, including improvements to
statement batching, query compilation caching, and more.
- Kodo now uses its own logging framework by default instead of the Commons
Logging framework.
There are a number of additional new features, notable changes and bugfixes.
For more information, please see
the release notes at:
http://www.solarmetric.com/Software/Documentation/3.1.0/docs/relnotes.html
Enjoy,

Note that there is a one-step upgrade process from 3.0. Kodo 3.1 uses
its own internal logging facilities by default. If you want to use the
same logging facilities (log4j, 1.4 logging, or whatever else you were
using), set the kodo.Log property like so:
kodo.Log: commons

Kodo JDO 2.5.0 beta now available

All,
Kodo JDO 2.5.0 beta 1 is now available at:
http://solarmetric.com/Software/beta/2.5.0/
Some notable new features since 2.4 include:
- Queries have received a major overhaul. Queries now support unbound
variables, Collections as parameters to generate SQL IN (...) clauses,
traversing fields of persistence-capable parameters, and more. The SQL
produced by queries is also much more efficient.
- Kodo JDO EE can now participate correctly in XA transactions.
- Kodo JDO now includes support for custom fetch groups.
- Queries and Extents can be constructed for interfaces.
- Multi-table mappings now permit different tables to have different
primary key column names.
- The data cache framework can now cache query results.
Known issues:
- The JCA resource adapter will not seamlessly work with WebLogic -- to
use it with WebLogic, it is necessary to unzip the kodo.rar and remove
empty config-param-value elements
(i.e. <config-properrty-value></config-property-value>).
- We have done only limited integration testing with our IDE plugins.
- Cached query results do not obey the timeouts configured for the classes
in the query's access path.

Kodo JDO 2.5.0 now available

All,
Kodo JDO 2.5.0 is now available. Thanks, everyone, for helping out
throughout the 2.5.0 public beta period. You're all great.
You can get Kodo JDO 2.5.0 at:
http://solarmetric.com/Software/Purchase/download.php
Major changes include:
- Major query modifications. Unbound variables are now supported,
Collections can be used as parameters in queries, and several SQL
inefficiencies have been addressed.
- Custom fetch group support.
- Kodo now supports incremental flushing of data to the database.
This can be useful in EJB environments when using container-managed
transactions, in order to handle any flush-related exceptions
within the bean code. It can also be useful in conjunction with
Kodo's automatic flushing capabilities to accelerate querying when
the javax.jdo.option.IgnoreCache property is set to false.
- Added JDOException subclasses for certain interesting exception
types: OptimisticLockException and ObjectNotFoundException.
- Enhancement-time metadata enhancement has been improved. This means
that you may see some errors the next time you re-enhance your
project, but that's for the best -- they were errors anyways.
- Data caching framework now caches JDOQL query results as well as
persistence-capable data. This provides dramatic acceleration for
commonly executed queries.
- The data caching framework has been reworked to separate out the
data cache capabilities from the remote event notification
capabilities. As a result, 2.5.0 data cache configuration is not
compatible with earlier data cache configuration, and custom cache
extensions will likely need some level of revision. For details,
see the release notes in the Kodo JDO Developer's Guide.

Kodo JDO 2.3.4 now available

All,
Kodo JDO 2.3.4 is now available at http://www.solarmetric.com/. This release
contains a number of bugfixes and a couple enhancements to the reverse
schema tool.
New features
* The schema generator can now accept a list of tables to generate.
* The reverse mapping tool has additional options for using foreign
key names to generate relation names, generating primitive wrapper-type
fields if a column is nullable, and allowing primary keys on many-to-many
join tables.
Bugfixes
* Fixed problems with many-to-many relations between tables that use
vertical inheritance.
* Fixed bug in schematool that caused it to not generate primary key
columns in subclass tables when using datastore identity + custom
names + vertical inheritance.
* Fixed serp library conflict between reverse mapping tool and main Kodo
libraries.
* Fixed a reverse mapping tool bug in which column names that conflicted with
Java keywords would result in the generation of uncompilable Java classes.
* Fixed problem that caused read-only flag to be ignored in many-to-many
relations.
* Multi-table inheritance deletes are now performed from the leaf table
in the inheritance chain up to the base table. Inserts are performed
from the base table down to the leaf. This supports the common
referential integrity model of establishing a foreign key relation
from inherited tables to their parent tables.
Enjoy!

An email will be sent out to owners of the query extension or caching
plugins sometime today (Tuesday).
You'll all be thrilled to hear that our spiffy new licensing system in
2.4 will not require multiple jars, which will make life easier for people
with plugins when upgrades are released.

Best regards,
The Beta 9.2 Team

The Beta 9.2 Team,
9.2 features sounds good and interesting. We are using BEA's Content management system(8.1) extensively.
Our requirement is to create a portlet for Content Owner/Users to create HTML documents with images and upload it into BEA Repository. Upon uploading, Content Admin needs to be notified through email and they will either approve or reject the document. The content status again needs to be notified to the content owner/user via email.
1. As known to everyone 8.1 doesn't have WYSIWYG editor and is included in 9.2. Can i reuse the 9.2 WYSIWYG functionality into 8.1 as a portlet??
2. The following thread(http://forums.bea.com/bea/message.jspa?messageID=400001479&tstart=0) says
- workflow ==> We have limited workflow support. We plan to enhance this in our next major release.
Does this limited workflow support include email notification?
Any inputs would be greatly appreciated!!
Thanks,
-Nach.
