How to use or manage UserTransaction API to persist jcr data in AEM nodes through OsGi service.

yes agree.. I came across the link and I m facing issues with setting context to UserTransaction Object.

No, I dont want to update JCR and data source simultaneously, I want to save all the JCR transactions once in the end, by utx.commit()  if there are no failure rates, and utx.rollback() in case of single failure. So I think if anyway we can make use of JTA transactions, to store transient data and submit and rollback as needed

repository = JcrUtils.getRepository("http://localhost:4502/crx/server");

   //Create a Session

javax.jcr.Session session = repository.login( new SimpleCredentials("admin", "admin".toCharArray()));

   Object sling;

//final SlingRepository repository = sling.getService(SlingRepository.class);

//   Session session = repository.loginAdministrative(null);

   Node root = session.getRootNode();

   Hashtable env = new Hashtable();

   Context ctx = null;

   env.put(Context.PROVIDER_URL, "http://localhost:4502/crx/server");

   env.put(Context.INITIAL_CONTEXT_FACTORY,"jcr/repository");

   ctx = new InitialContext(env);

   UserTransaction utx = (UserTransaction)

     ctx.lookup("javax.transaction.UserTransaction");

Why would you use javax.transaction API? The JCR session API already offers transaction support. Of course you cannot span a transaction multiple datasources (for example a SQL database which should be updated in the same transaction as JCR).

It's that what you want to do?

Not a lot of transaction inforomation online about JCR and transactions. See this doc that may help -- JCR 2.0: 21 Transactions (Content Repository for Java Technology API v2.0)
