public class TransactionDroplet
extends DynamoServlet

The TransactionDroplet is used in a page to enclose an area of a page within its own transaction context behavior. Several transactional behaviors are available - the same set available for EJB's. The "output" OPARAM is rendered within the context of the specified transactional behavior. If any transaction-related error occurs, the "errorOutput" OPARAM is rendered after the "output" OPARAM is rendered, otherwise the "successOutput" is rendered after the "output" OPARAM is rendered. If a transaction-related error occurs before the "output" OPARAM is rendered, then the "output" OPARAM will not be rendered but the "errorOutput" OPARAM will.

The TransactionDroplet takes the following parameters:
