Upgrade Guide
The Utility adapters, Email and File, in WebLogic Integration 2.1 SP2 and WebLogic Integration 7.0 SP2, have been replaced in WebLogic Integration 8.1 with system features. Consequently, these two adapters cannot be upgraded and you will need to replace their implementation with the new features.
Note: The Adapter for RDBMS had been replaced by a new RDBMS Adapter for 8.1 and has new capabilities.
The following table shows the WebLogic Integration 2.1 and WebLogic Integration 7.0 SP2 adapters and their replacement in WebLogic Integration 8.1.

Email controls enable WebLogic Integration business processes to send e-mails to specific destinations. To learn more about Email controls, see Email Control in the WebLogic Workshop Help at the following URL:

Business processes use Email event generators to read e-mail messages from a Post Office Protocol (POP3) or Internet Message Access Protocol (IMAP) account on a mail server and publish the contents to Message Broker channels.

File controls read, write, or append to a file in a file system. The files can be one of the following types: XmlObject
, Binary (raw data), or String
. In addition, the File control supports file operations such as copy, rename, and delete. Typically, you use these operations to manipulate large files, without having to process them in any way.

File event generators poll for files in file systems and publish the files to Message Broker channels. Business processes use File event generators to receive events—for example, a business process receives an event when a file appears in a file system that is polled by a File event generator.
