DBWS Road Map

2.2

Items 'above the line' are under development or potential development items for this release. Items below the line have been completed for this release

• DBWS should support batch SQL operations bug 326953
  • New enhancement request, needs scoping out
  • Request to put transaction-handling SQL into the DBWSBuilder file (encompassing more than one SQL statement)
• 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'
• DBWS Server tests
  • expand existing WLS server tests to run on WAS, JBoss and Glassfish
  • TBD: expand test coverage - what additional tests are useful?
• AQ Web Services bug 322950)
  • Investigate how to support; add usecase to DBWS section of User Guide
  • Highlighted as lower priority
• DBWSProvider does not handle package REF CURSOR bug 325124
• DBRS
  • Look at role of DBWS in RESTful web applications

---

Completed in EclipseLink2.2

• 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 also available in EclipseLink2.1.2
• 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
• Jetty/Equinox support (done)
  • DBWS deployed 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

Backlog of work items

These items are not currently targetted for a specific release. Future Bugs

• 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)
  • Use 'orm.xml' and 'oxm.xml' for metadata
• 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
• 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
• Jetty/Equinox support
  • TBD: Glassfish's Felix and HK2

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:

1. table: CRUD lifecycle
2. Stored Procedure: specialized queries
3. Result set: returned from SQL SELECT queries
