I have to call a C program from WMQI2.1. I have to pass few parameters from an incoming XML message to this C program and the output from that C program has to be mapped to Output XML message.
I think there is a possibility to build a Custom Node(in Java or C) and call an external program from that Custom Node. But in the documentation it is mentioned that Interfacing a C-Plugin to Java and wrappering in JNI is not supported because the broker internally initializes a JVM, which is not available for the plugin interface.
So developing a Custom Node in C is the only solution or is there any other way to do this? |

Hi,
A C custom node is probably the easiest way to do this.
PS Do you know 2.1 is about to go out of service?

To be clearer, 2.1 goes out of service at the end of this month.
And, really, I don't think you need to bother with a custom plug-in at all.
Write a standard MQ program that acts as a server in a request/reply scenario and use aggregation to fetch the response and update the input message.
