I'm currently developing a req/reply flow which includes aggregate nodes.
I have to store a certain value obtained from the request message in the local environment as i would need to retrieve the value and consolidate it with the reply message later.

Okay, here's a newbie question. Can the value stored in the Local Environement (during the request flow) be retrieved later during the reply flow? If yes, how can it be done now? Please advice ... TQ

I'm currently on WMQI V2.1 with CSD 2 running on Win2K.

Hi. Another question related to the same agg req/reply flow. I'm encountering the error BIP2291E.

BIP2291E: No constant for parser class name for root element name 'ComIbmAggregateReplyBody'. The message broker could not locate a constant for a parser class name for a root element name.
Contact the author or supplier of the loadable implementation library implementing the parser to check whether or not the constant has been registered. If it has not, install an updated version of the loadable implementation library. If registration has taken place, contact your IBM support center.

This is stopping my development work. Any ideas on what the error msg means? TQ.

You can't just output the aggregated message as no parser exists to handle it.

You must construct your own output message in a compute node - this can be a few lines of ESQL to create an XML message from the aggregated message.

Please read chapter 10 of redbook SG24-6509-00.
