DBWS Road Map
2.3
- DBWS should support batch SQL operations bug 326953
- Request to put transaction-handling SQL into the DBWSBuilder file (encompassing more than one SQL statement)
- DBWS Server tests
- expand existing WLS server tests to run on WAS, JBoss and Glassfish
- TBD: expand test coverage - what additional tests are useful?
- 329435 - DBWS does not handle %ROWTYPE mix of PL/SQL types and JDBC Advanced types
- Eclipse IDE based integration for the DBWS tooling
- Need to provide an API that gives us the capability to specify where to find the driver class files
- Build environment
- Plan to include DBWS feature in SDK bundle made available in p2 repository
Completed in EclipseLink2.3
- .
Backlog of work items
These items are not currently targetted for a specific release. Future Bugs
- bug 234385 Support optional arguments for Stored Procedures (requires core Foundation work)
- 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
- bug 303333 Handle overloaded Stored Procedure/Functions as WSDL operations
- bug 332221 Support Stored Procs returning multiple rowsets.
- Brand new core capability. Only for those platforms (Sybase, MySQL) that support it
- AQ Web Services bug 322950)
- Investigate how to support; add usecase to DBWS section of User Guide
- Highlighted as lower priority
- 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'
- DBWSProvider does not handle package REF CURSOR bug 325124
- DBWS for PL/SQL procedure with out ref cursor parameter fails at runtime
- DBRS
- Look at role of DBWS in RESTful web applications
- bug 300398 - Add "get(String, Class)" method to DynamicEntity
- Align DBWS internal metadata with JPA/JAXB metadata (requires JPA/JAXB 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 305522 Dynamic Entities do not work with JPA 2.0 Criteria Queries
- 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
- Development tooling support through IDEs
- Manageability features for DBWS
- Provide exposure through MBeans to show underlying SQL query, etc
- DBWS running under OSGi: test on other platforms
2.2
- For DBWS Custom SQL usecases, get resultSet metadata at design-time to build eclipselink-dbws-schema.xsd (Custom SQL Design-time Schema, bug 322949)
- use ResultSetMetaData to build DbColumn's and from that, a schema
- Feature available in EclipseLink 2.1.2
- 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
- DBWS running under OSGi (done)
- DBWS as OSGi bundle
- Environment: Equinox + Jetty server
- Documented here
- DBWS cannot execute certain Stored Procedure on MySql/J 5.1.13 bug 326804
- EclipseLink2.2 bugs: OPEN
- EclipseLink2.2 bugs: RESOLVED
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
