Error Messages
The developer writes servlets that use connectors to connect with the back end. Error messages are generated to assist the developer in debugging these processes. This appendix contains a list of identified errors and the error handling code that is used to identify the error.
The following topics are described:
Description of Errors
Table A-1 lists the error handling codes, msgid, and the corresponding messages.

Error Handling Code
The error handling code is an example of how to handle an exception raised by the connector.
When there is an error in the process, the iPlanet Application Server Enterprise Connector for R/3 throws a BspException object. The exception object contains a data object. The data object contains the numeric code, msgid, as listed in Table A-1.
An example of error handling code is shown in Code Example A-1.
Code Example A-1 Error Handling Code Sample
try
|
|
{
|
|
... some code in the servlet
|
|
}
|
|
catch (BspException e)
|
|
{
|
|
IBSPDataObjectStructure info = null;
|
|
errorMessage += " Error : " + e.getMessage() ;
|
|
info=e.getInfo();
|
|
if (info != null && info.attrExists("msgid") )
|
|
{
|
|
errorMessage += " Error code : " + info.getAttrInt("msgid")
;
|
|
}
|
|
}
