> Recent developments in web standards (HTML5, specifically Web Storage a.k.a. DOM Storage) indicates a move towards widespread availability of client (i.e. web browser) side persistent storage accessible by web applications. Initially useful for making content and applications available offline, this also open up the possibility of object replication between client and server. In this project you will explore the applicability of transaction concepts to applications built on this model. In particular, you will focus on identifying and exploiting new opportunities made available by the existence of persistent storage on the browser, a vital pre-requisite for recoverable transactions.
> To undertake this project you should have a strong interest in web based applications, some javascript programming experience and a basic understanding of transactions concepts. Previous experience of at least one javascript framework would be an advantage. The work will be open source.

> Increasingly sophisticated applications are being implemented using the javascript language. Initially popular for browser based environments, the language is also gaining traction on the server side (NodeJS, etc). A single threaded model promotes use of callbacks and asynchronous I/O operations. Ongoing standardization work is starting to provide APIs for enterprise functionality (commonJS, IndexedDB, etc). The Rhino javascript engine allows javascript to run on any JVM. These factors lead to situations where distributed business applications may be written wholly or partially in javascript and may need to interact with existing business logic or services implemented in Java. In this project you will consider how to provide transaction management capabilities to such applications.
> This project will require a good knowledge of javascript programming, ideally encompassing a server side javascript environment. Candidates should also possess some knowledge of Java and transaction concepts. The work will be open source.

[JBoss JIRA] (JBTM-622) Support for crash recovery of tx-inflow with multiple resource managers

> JCA tx-inflow spec allows the external EIS to provide the Xid for the inflowed transaction. The TM handling the inflowed (i.e. subordinate) transaction uses this Xid verbatim when talking to RMs.
> In current implementation, each RM enlisted in the subordinate tx will see the same Xid as originally provided by the EIS. This screws recovery where multiple resources are involved, since a given Xid no longer belongs to exactly one RM, but may be shared by several. We can no longer return a single XAResource to drive the recovery for a given Xid.
