Handling Exceptions

The Client Object API defines server-side and client-side exceptions.

• Server-Side Exceptions
  A server-side exception occurs when a client tries to update or create a record and the Unwired Server throws an exception.
• HTTP Error Codes
  Unwired Server examines the EIS code received in a server response message and maps it to a logical HTTP error code, if a corresponding error code exists. If no corresponding code exists, the 500 code is assigned to signify either a Sybase Unwired Platform internal error, or an unrecognized EIS error. The EIS code and HTTP error code values are stored in log records.
• Mapping of EIS Codes to Logical HTTP Error Codes
  A list of SAP® error codes mapped to HTTP error codes. By default, SAP error codes that are not listed map to HTTP error code 500.
• Client-Side Exceptions
  Device applications are responsible for catching and handling exceptions thrown by the client object API.
