org.castor.persist.TransactionContext.prepare()

Prepares the transaction prior to committing it. Indicates whether the transaction is read-only (i.e. no modified objects), can commit, or an error has occured and the transaction must be rolled back. This method performs actual storage into the persistence storage. Multiple calls to this method can be done, and do not release locks, allowing checkpoint to occur. An IllegalStateException is thrown if transaction is not in the proper state to perform this operation. @return True if the transaction can commit, false if the transaction isread only @throws TransactionAbortedException The transaction has been aborted due toinconsistency, duplicate object identity, error with the persistence engine or any other reason.

        case Status.STATUS_PREPARED:
        case Status.STATUS_ACTIVE:
            // Can only prepare an active transaction. And error
            // is reported as vote to rollback the transaction.
            try {
              return tx.prepare() ? XA_OK : XA_RDONLY;
                
            } catch (TransactionAbortedException except) {
                throw new XAException(XAException.XA_RBROLLBACK);
            } catch (IllegalStateException except) {
                throw new XAException(XAException.XAER_PROTO);
