DBWS Road Map
Backlog of work items
- bug 300398 - Add "get(String, Class)" method to DynamicEntity
- bug 275156 Support complex PL/SQL arguments for Stored Functions
- Currently, complex schemas are generated for the arguments to named Stored Procedures that are PL/SQL collection/records or JDBC Object/Varrays; Need to extend this capability to Stored Functions
- requires core Foundation work
- Align DBWS internal metadata with JPA/JAXB metadata (requires JPA/JAXB work)
- Support optional arguments for Stored Procedures (requires core Foundation work)
- bug 290156 Validate SOAP message arguments (must be very efficient!)
- Currently perform no validation on objects passed via SOAPMessage. While complete validation is likely to be prohibitively expensive, some validation could result in errors better than "java.lang.reflect.InvocationTargetException"
- bug 303333 Handle overloaded Stored Procedure/Functions as WSDL operations
- bug 305522 Dynamic Entities do not work with JPA 2.0 Criteria Queries
2.2
{divide items into 'above the line' and 'below the line' - items above the line require new DBWS development; items below the line are either i) done or ii) being investigated in parallel}
- DBWS Sparse Merge (bug 322948)
- Sparse merge requirements
- build on top of newly-added support for Sparse Merge for Dynamic Persistence
- add usecase to DBWS section of User Guide
- nightly JUnit testing
- For DBWS Custom SQL usecases, get resultSet metadata at design-time to build eclipselink-dbws-schema.xsd (bug 322949)
- add additional term (1=0) to WHERE clause
- need either a GUI so that a user can indicate the correct place to add term, or a reliable parser that can handle arbitrarily complex WHERE clauses
- result set metadata using OracleResultSetMetaData?
- add additional term (1=0) to WHERE clause
- AQ Web Services
- Investigate how to support; add usecase to DBWS section of User Guide
- DBRS
- Look at role of DBWS in RESTful web applications
- Jetty/Equinox support (mostly done)
- DBWS Server tests
- expand existing WLS server tests to run on WAS, JBoss and Glassfish
- TBD: expand test coverage - what additional tests are useful?
- Distributed transactional support via WS-AT
- Q1: Is WS-AT policy even supported for Dynamic JAX-WS Endpoints?
- Q2: If Q1 == true, what role does DBWS play? Adding the policy annotation is done completely through JDev 'Policy Inspector'
- need expert help
- JPub -> EclipseLink DBWS migration strategy
- Need to document a path explaining steps a user needs to take to switch from JAX-RPC based technologies to DBWS (JAX-WS) solution
2.1
- accommodate internal changes for AttributeChangeTracking
- support DBWSBuilder-generated JAX-WS Provider on JRockit
- stop DBWSBuilder from truncating GROUP BY/ORDER BY clauses
- DBWSBuilder supports Eclipse WTP Dynamic Web Project structure
2.0.1
- align DBWS internal implementation with new Dynamic Persistence features
- DBWSBuilder utility auto-detect Optimistic Lock field
- fix issue with JDBC metadata and overloaded Stored Functions
- Support MTOM attachments
- fix Web service faults: contain better server-side root cause information
1.2
- For OraclePlatform, support advanced PL/SQL datatypes (records, collections, mixture of the two) as arguments to Stored Procedures
- need compatible JDBC 'shadow' types to align with PL/SQL types
- For OraclePlatform, support complex JDBC datatypes (objects, varrays, mixture of the two) as arguments to Stored Procedures
- Fix WSDL inline-schema to support above complex args
- Add support for SOAP 1.2
- Fix Delete operation (part of table-based CRUD): use only PK fields, not whole instance
- Use nillable="true" to represent database null
- DBWSBuilder utility to produce DDL for the compatible JDBC shadow types
1.1
- Deploy to JAX-WS 2.n complaint server (WebLogic 10)
- For OraclePlatform, support simple PL/SQL datatypes (PLSINTEGER, BOOLEAN, etc) as arguments to Stored Procedures
- Improve server-side exception handling
1.0
The focus is on providing capabilities based upon the 3 types of database artifacts:
- table: CRUD lifecycle
- Stored Procedure: specialized queries
- Result set: returned from SQL SELECT queries
