public class JboExHelperLocalized

extends JboExceptionHelper

The superclass for localized exceptions for Business Components.

This class provides tools for localizing exception messages for various target languages, and for message formatting.

Message-text localization occurs when the client calls getLocalizedMessage(), rather than at time the exception occurs, because the client may need to present the message in a number of different languages.

The components of a message are:

• a non-translated product code string, such as "FRM" or "ORA".
• a non-translated error code string, such as "10234"
• non-translated message text.
• message parameters, equal in number to the number of '%' symbols in the message text.
• a "details" list containing background information.

Additional components may be introduced in future.

A counterpart subclass of ResourceBundle, JboExceptionBundle, is used to determine the overall formatting of the message. The default format is

productCode-errorCode: messageBody

For example, ORA-10234: I don't think so.

Most subclasses wll provide a value for the error code in a specialized constructor.

Applications may define subclasses of most JBO exceptions. To do this the application should override the following methods to provide the correct set of values for the messaging services:

• getResourceName
to return the name of the appropriate resource bundle.
• getProductCode
to return the name of the product.

Other methods may be overridden to modify the message format.
