• Before You Begin

• General Guidelines

This topic describes how to integrate transactions in RMI applications that run under BEA WebLogic Enterprise.

Before you begin, you should read Introducing Transactions, particularly the following topics:

• Transactions in WebLogic Enterprise RMI Applications

• Transactions Sample RMI Code

For more information about RMI applications, see Using RMI in a WebLogic Enterprise Environment.

The following general guidelines apply when implementing transactions in RMI applications for WebLogic Enterprise:

• WebLogic Enterprise allows for flat transactions only. Transactions cannot be nested.

• For RMI applications running under WebLogic Enterprise, the AUTOTRAN setting (if specified) in the INTERFACES section of the UBBCONFIG file is ignored.

• Use standard programming techniques to optimize transaction processing. For example, properly demarcate transaction boundaries and complete transactions quickly.

• For RMI applications, callback objects are not recommended for use in transactions because they are not subject to WebLogic Enterprise administration. For more information about callback objects, see "Using RMI with Client-side Callbacks" in Using RMI in a WebLogic Enterprise Environment.

For general guidelines about the WebLogic Enterprise Transaction Service, see Capabilities and Limitations.
