...

The Database Connector can be deployed in any servlet container i.e.tomcat or in Standalone mode.

Enhancements:

• #18166 - Batch processing of POST/Create requests. JDBC inserts are batched instead of performing individual inserts.
• Logging improvements
• KIOSK mode - when no configuration.xml is defined, the KIOSK mode pre-loads BIRT (ClassicModels) and myStore QuerySets with in-memory Derby databases. This will make it very easy to try out the DB Connector.
• #19243 - Support for JSON payload from business rules when performing POSTs and PUTs.
• #20546 - Query statements are validated when the DB Connector starts instead of when used.
• Console prints the DB Connector version and revision number.
• #18620 - Generating max-length for SQL Server NVARCHAR
• #20532 - Ability to disable QuerySets and/or Querys while developing your integration.
• #18708, #18676 - Returns blank or null in the JSON results for columns that have blank or null values..
• The database.war is  executable - there is the option to either deploy the WAR in an existing Servlet Container or simply run the WAR in standalone mode (with java -jar dbconnector.war).
• The SQL Server JDBC driver is included in the Database connector war.
• QuerySet and Query names only allow alphanumeric, dot, dash and underline characters. They must start with letters. This change makes sure that they are automatically XML and JSON friendly.
• The driver and validationQuery attributes in <resource-def> are now optional: they will be properly inferred based on the current database.
• The configuration.xml file is automatically picked up from the current directory where the DB Connector was launched or from ./config/configuration.xml. It can be manually set by using the frevvo.connectors.database.configuration property as before. This is specially useful when running the DB Connector standalone.
• #9564 - Ability to generate schemas for all queries in a queryset. This makes it possible to download a single XSD for all queries at once.

Tickets Fixed:

• #19062 - MySQL column w/ timestamp datatype failing when trying to insert date/time control value.
• #9244  -  http.post() to DB connector not working from rules for URL parameters and JSON payload in POST/PUT requests.
• #9565  -  A query with '<' sign in it does not work.
• #12750 - DB Connector:Support PUT/POST for European Characters.
• #13134 - Database POST fails when there is % character in one of the fields.
• #18620 - SQLSERVER : Datatype nvarchar does not generate max-length restrictions   
• #18207 - Errors while inserting, updating, selecting row(s) using the DB connector are simply logged and ignored: it always returns an HTTP 200 status code.
