Subject [jira] Created: (GERONIMO-2127) Expose the ability to use Select for Update on CMP entity beans

Expose the ability to use Select for Update on CMP entity beans

         Key: GERONIMO-2127
     Project: Geronimo
        Type: Improvement
    Security: public (Regular issues) 
 Environment: All
    Reporter: Matt Hogstrom
     Fix For: 1.1.1

Currently TranQL supports the generation sql to execute a select for update.  Unfortunately,
OpenEJB does not expose the ability in the current XSD to support this.  As a result the CMP
implementation we have does pass CTS but lacks the ability to deploy an application that is
performant and provides for data consistency.

This improvement will add an attribute into the XSD for OpenEJB so a new attribute will be
added <select-for-update> that is an indicator to use a select for update on a query
so database locking can be employed.

Changes will be made to TranQL (Syntax Factories) to create the correct SQL as well as OpenEJB's
CMP builders to honor the request.
