ExHandler.cs is used to handle SOAP Exceptions that may be encountered when making Cognos service requests. The ExHandler.cs class allows you to display a meaningful error message to the end user. It captures the severity, error code, message and details of the exception that has been encountered. These values are appended and returned as a string.
This is example code to capture the Exception’s severity.
/// Return the exception severity. ///
public string Severity{
get{
XmlNode severityNode = exSoap.Detail.SelectSingleNode( "//severity");
if (severityNode != null)
{
return severityNode.InnerText;
}
return "";
}
}
Your web solution should have all of it’s TRY-CATCH statements updated in order to reference the functionality ExHandler.cs class file. You would simply have to instantiate the object in your updated Catch statements.
ExHandler exCognos = new ExHandler(exSoap);
Here is a more detailed example showing the updated Catch statement and appending a string object with the full exception message.
try
{
_cmService = new contentManagerService1();
_rptService = new reportService1();
_dispC8 = ConfigurationSettings.AppSettings["CognosDispatcher"];
_NmSpace = ConfigurationSettings.AppSettings["CNmspace"];
_Pwd = ConfigurationSettings.AppSettings["CTSpwd"];
_Uid = ConfigurationSettings.AppSettings["CTSuid"];
_CSTypePkg = ConfigurationSettings.AppSettings["CSTypePkg"];
_CSTypeRpt = ConfigurationSettings.AppSettings["CSTypeRpt"];
_cmService.Url = _dispC8;
_rptService.Url = _dispC8;
_cogSDK = new CognosSDK();
_cogSDK.CognosLogon(_cmService,_NmSpace,_Uid, _Pwd);
_rptService.biBusHeaderValue = _cmService.biBusHeaderValue;
}
catch (SoapException exSoap)
{
ExHandler exCognos = new ExHandler(exSoap);
_ErrMsg = exCognos.Details + " :-: " + exCognos.Message + " :-: " + exCognos.Severity + " :-: " + exCognos.ErrorCode;
}
catch (Exception ex)
{
_ErrMsg = ex.Message.ToString();
}
