Supporting this JSR: IBM Section 2: Request
2.1 Please describe the proposed Specification:Background The J2EE Connector Architecture 1.5 defines a standard architecture for connecting to heterogeneous Enterprise Information Systems (EIS) in both synchronous and asynchronous mode. It also provides a pluggability layer for JMS (Java Message Service) and JDBC (Java Database Connectivity) providers. Proposal The purpose of the Java EE Connector Architecture 1.6 specification is to address areas in J2EE Connector Architecture 1.5 where further support has been requested by the Connector expert group and the public. The areas this specification intend to address are the following: Generic Inflow Context Connector Architecture 1.5 supports transaction inflow context. The WorkManager contracts are closely tied with transaction inflow context. This feature will enhance the transaction inflow context to a more generic context to accommodate additional functionality like security. The WorkManager mechanism will be made more flexible and independent of the Inflow contracts. General Improvements to the Connector 1.5 specification.
The existing connector 1.5 specification will be reviewed and strengthened.
Following is an initial list of areas considered for this activity. Note that
this list is not a final list and hence all items in this list may not be
completed in the timeframe of this specification whereas some other items which
are not present in the list might be taken up.
Ease of Development Following the common programming model for Java EE, this expert group will also consider making resource adapter development easier by defining helper classes and annotations for the Connector API wherever applicable. This simplification will be applicable for both inbound and outbound areas of the connector API. 2.2 What is the target Java platform? (i.e., desktop, server, personal, embedded, card, etc.)This specification is targeted for Java EE. 2.3 The Executive Committees would like to ensure JSR submitters think about how their proposed technology relates to all of the Java platform editions. Please provide details here for which platform editions are being targeted by this JSR, and how this JSR has considered the relationship with the other platform editions.The Java EE Connector architecture is specifically designed for the Java EE platform environment. 2.4 Should this JSR be voted on by both Executive Committees?No. It should be voted on by the Java SE / EE Executive Committee only. 2.5 What need of the Java community will be addressed by the proposed specification?The goal of the proposed specification is to address the needs of the Java community by augmenting the functionality of J2EE Connector Architecture to address requests received from the Java community and the expert group for additional features. 2.6 Why isn't this need met by existing specifications?See 2.5 above. The existing J2EE Connector Architecture 1.5 specification does not address the areas described in section 2.1. Vendors and developers are forced to use implementation-specific architectures or contracts, resulting in non-portable solutions. 2.7 Please give a short description of the underlying technology or technologies:The J2EE Connector Architecture is based on the technologies that are defined and standardized as part of the JavaTM EE platform environment. Specifically, the J2EE Connector Architecture leverages concepts and mechanisms defined by Java EE, Java Transaction API (JTA), JDBC and JMS specifications. 2.8 Is there a proposed package name for the API Specification? (i.e., javapi.something, org.something, etc.)The API specification will continue to use the javax.resource package and its subpackages. 2.9 Does the proposed specification have any dependencies on specific operating systems, CPUs, or I/O devices that you know of?No 2.10 Are there any security issues that cannot be addressed by the current security model?No 2.11 Are there any internationalization or localization issues?No 2.12 Are there any existing specifications that might be rendered obsolete, deprecated, or in need of revision as a result of this work?No. This is an update to JSR 112: J2EETM Connectors Architecture 1.5 2.13 Please describe the anticipated schedule for the development of this specification.We hope to deliver the final specification, reference implementation, and TCK in the Q4 of 2008. A rough estimate of the schedule would be
December 2007 Expert group formed 2.14 Please describe the anticipated working model for the Expert Group working on developing this specification.The primary means of communication will be email and conference calls. Face-to-face meetings will be scheduled if needed. We will solicit feedback from the community. See section 2.15 for the transparency measures we will use. 2.15 It is important to the success of the community and each JSR that the work of the Expert Group be handled in a manner which provides the community and the public with insight into the work the Expert Group is doing, and the decisions that the Expert Group has made. The Executive Committees would like to ensure Spec Leads understand the value of this transparency and ask that each JSR have an operating plan in place for how their JSR will address the involvement of the community and the public. Please provide your plan here, and refer to the Spec Lead Guide for a more detailed description and a set of example questions you may wish to answer in your plan.The Expert Group will publish early drafts for review by the community at convenient points during the development of the specification. The Expert Group will solicit feedback from the community via public fora(e.g., public presentations, blogs, and other online postings). 2.16 Please describe how the RI and TCK will de delivered, i.e. as part of a profile or platform edition, or stand-alone, or both. Include version information for the profile or platform in your answer.Sun will deliver a Reference Implementation (RI) and Technology Compatibility Kit (TCK). The RI will be made available as part of the Java EE 6 RI. The TCK will be delivered both standalone and as part of the Java EE 6 TCK. 2.17 Please state the rationale if previous versions are available stand-alone and you are now proposing in 2.13 to only deliver RI and TCK as part of a profile or platform edition (See sections 1.1.5 and 1.1.6 of the JCP 2 document).N/A 2.18 Please provide a description of the business terms for the Specification, RI and TCK that will apply when this JSR is final.Pursuant to Section 2.2.1 of the Java Community Process version 2.6, the following is a summary of Sun's anticipated principal license terms and conditions for the JSR, Java EE Connector Architecture 1.6. The Java EE Connector Architecture 1.6 Technology Compatibility Kit (TCK) will be available both as a standalone TCK and included as part of the Java EE 6 Compatibility Test Suite (CTS). The Java EE Connector Architecture 1.6 Reference Implementation (RI) will be available as part of the Java EE 6 RI. The TCK license does not limit how a compatible implementation of the specification can be used or distributed, e.g., by limiting the hardware devices or operating environments that can be supported. Non-Commercial Use As required by the Java Specification Participation Agreement (JSPA), the Java EE Connector Architecture 1.6 TCK will be licensed at no charge without support to qualified not-for-profit entities. Such qualification will be verified by the Compatibility Testing Scholarship Program. Support may also be provided at no charge with approval of the scholarship board. For more information, please refer to: http://java.sun.com/scholarship/. The RI will be available at no cost under an open source license as part of the Java EE 6 RI. Commercial Use Covers all use that doesn't fall under "Non-Commercial Use" above. Java EE Connector Architecture 1.6 TCK Java Licensee Engineering (JLE) support, available for a fee not to exceed $50k, is required for commercial use for each Marketed Product* which implements the Java EE Connector Architecture 1.6 specification. TCK JLE support includes access, updates and upgrades to the TCK at no additional charge. Java EE Connector Architecture 1.6 RI and TCK JLE and marketing support will be made available at no extra charge to Java EE licensees under their Java EE business terms. The RI will also be made available at no cost under an open source license for commercial use as part of the Java EE 6 RI. For purposes of these terms: Marketed Product is intended to describe a licensee's product that has its own differentiation and marketing collateral. It may comprise one price list entry, or in some cases multiple entries (for example, to account for different localizations or delivery packaging). By way of example, in terms of Sun's product line we wouldn't consider Sun's Java Application Server to be a Marketed Product, but Sun's Java Application Server Platform Edition, Standard Edition, and Enterprise Edition are 3 Marketed Products. Sun's Java Studio Enterprise is a fourth Marketed Product. Section 3: Contributions
