We are trying to build a message flow (error description flow) to provide some meaningful error description to our end user by analyzing the Exceptionlist of any message flow or broker exceptions caught. We found the “Text” field under ----Exception (such as RecoverableException, ParserException, ConversionException …..) normally contains reasonably easy to understand descriptions. We also see “Text” field under each insert which may or may not contain information. Also the description, if exist, are not very easy to understand by users who are not trained on the product. Hence we want to use the “Text” field under ----Exception.
However in the infocenter under the topic “ExceptionList tree structure”, there is a footnote saying
“Do not use the File, Line, Function, and Text elements for exception handling decision making. These elements ensure that information can be written to a log for use by IBM service personnel. “
Does it mean that we should not be using that field for the purpose? I was wondering if that means IBM may use the field for other things in the future which can make our "error description" flow useless ? |

Put it in an Insert.
Don't modify an ExceptionList tree yourself.

Hi jefflowrey, thanks for the quick response. I think I was not clear on my description. I am not changing any field of the exceptionlist. I just want to use the field of the exceptionlist to output, for example, an xml message to the end user. I was wondering if I should use the "Text" field under
"---Exception "
For example in a ParserException as shown in the trace below, I have
"'CPI Text Buffer Input Data Too Short'" in ParserException.Text.
I also have 'CWFWorker::ReadDataFromBitstream' in insert.Text. Of course the Text field under ParserException is more meaningful to a general user than what is in the Text field under insert. So I was planning to output that as a description to my end user until I saw the footnote I mentioned above. This footnote gives me the impression that I should not use it. Any suggestion ?
(0x01000000):ParserException = (
(0x03000000):File = 'F:\build\S600_P\src\cpi\pwf\cwf\cwfreader.cpp'
(0x03000000):Line = 398
(0x03000000):Function = 'CWFWorker::ReadDataFromBitstream'
(0x03000000):Type = ''
(0x03000000):Name = ''
(0x03000000):Label = ''
(0x03000000):Catalog = 'BIPv600'
(0x03000000):Severity = 3
(0x03000000):Number = 5503
(0x03000000):Text = 'CPI Text Buffer Input Data Too Short'
(0x01000000):Insert = (
(0x03000000):Type = 2
(0x03000000):Text = '3'
)
(0x01000000):Insert = (
(0x03000000):Type = 5
(0x03000000):Text = 'CWFWorker::ReadDataFromBitstream' |

It doesn't say not to use them.
It just says not to use them for decision making.
I think what is meant here is that the Text descriptions put into the Inserts are subject to change, but the the BIP number isn't. The sentence you quoted is probably there to allow the Broker development team to change these at whim, without worrying if someone's production environment will break.
So use them, but don't rely on them.
