MQSeries.net :: View topic - Accessing optional RFH2 folders from C/C++

Hi,

The scenario I have is that an XML message passes through a MQSI 2.1 flow, arriving on a queue where some business/status data has been stored in a <usr> folder in the MQRFH2 header. This message is intended to be processed by a legacy C program which I'm able to amend. Identifying and stripping off the MQRFH2 header (before the rest of the message is fed to an XML parser to be turned into a tree) is straightforward as the total length is in the static part of the header.

Before I reinvent a wheel, does anyone have some cunning code for accessing the optional folders (mcd et al) at the end of an RFH2 header, or can I be pointed in the direction of a manual / support pac / etc?

Secondly, what's the perceived wisdom on using C these days? As it's being changed is it "better" to take a hit and rewrite it in C++? Does it simplify header processing? I have some lattitude with this, being both architect and coder.

Thirdly, and least importantly, my only real limitation is I can't convert it into Java. Slight shame as I understand access to JMS makes this sort of folder processing easy(ier). Is this true and would it make sense to migrate from C/C++ to Java?

Many thanks for any assistance / advice offered.
