public class EndTransactionDroplet
extends DynamoServlet

The EndTransactionDroplet is used in a page to "manually" commit or rollback the current transaction. Any errors that occur during the commit or rollback process are reported to an OPARAM, thereby allowing the application to report transaction failures to the user. Any errors that occur are also logged.

The EndTransactionDroplet takes the following parameters:

• "op" - the value of this attribute must be either "commit" or "rollback", indicating how that transaction should be ended.
• "errorOutput" - this is an optional OPARAM that will be executed if an error occurs during the commit or rollback. Within the OPARAM, the error will be communicated through the following parameters:
  • "errorMessage" - a text message indicating the error
  • "errorStackTrace" - the full stack trace of the error
• "successOutput" - this is an optional OPARAM that will be executed if the commit or rollback operation completes successfully.
