> The general approach would be along the lines of:
> Startup
> ======
> Embedded embedded = EmbeddedFactory.create();
> embedded.startup();
> embedded.deploy(new File("my-rar.rar").toURI().toURL());
> embedded.deploy(new File("my-ds.xml").toURI().toURL());
> In use
> =====
> InitialContext initialContext = new InitialContext();
> UserTransaction ut = (UserTransaction)initialContext.lookup("UserTransaction");
> DataSource dataSource = (DataSource)initialContext.lookup("java:/"+"TestDS");
> Shutdown
> =======
> embedded.undeploy(new File("my-ds.xml").toURI().toURL());
> embedded.undeploy(new File("my-rar.rar").toURI().toURL());
> embedded.shutdown(); // does not work - some threads don't stop
> Problems?
> =========
> JCA transitive dependencies?
> Accessing ds files from war?
> Accessing rar from war?
> May have to provide these both upfront.

[JBoss JIRA] (JBTM-1472) JTA for Compensations
by Tom Jenkinson (JIRA)

> Reporter: Paul Robinson
>
> We essentially provide a JTA-like implementation for using compensations. We would support distribution over Web services and REST via WS-BA and REST-JDI. This is similar in how we do distributed ACID transactions today; the application is developed against the JTA, but through configuration we enable distributed transactions over a particular transport (remoting, IIOP, WS).
> It would be good to have some subset of functionality that worked on a raw VM (i.e. no appserver). This would hopefully broaden the market.

> During profiling, BeanPopulator can represent a 7% overhead. It may not seem like a lot, but for something as relatively simple as what BeanPopulator should be doing, it seems to be quite a bit.
