can I get help some help in understanding a snippet from one of the Red Books
| Quote: |
7.1 Description of Java plug-in nodes
Plug-in nodes, or custom nodes, can be written in C or Java. A broker extension
or plug-in parser can only be written in C. The files are then distributed as:
A shared object on UNIX systems, named with a filetype of .lil (loadable
implementation library).
A dynamic link library (DLL) on Windows systems, again with a filetype of .lil
A Java Archive file (JAR), with a filetype of .jar
The plug-in is loaded when the broker is initialized. Registration functions in the
plug-in are invoked so that the broker understands what nodes or parsers are
supported by the plug-in.
The programmer must avoid the use of operating system-specific functions. This
enables them to work on a variety of platforms with re-compilation only, without
any change to the source code.
Java can only be used to write plug-in processing nodes or input nodes. |
any directions for searching red book for plug-in nodes in C

One of the first Red Books for MQSI had a major section on writing a PlugIn in C. It was SG24-6154 Business Integration Solutions with MQSeries Integrator.
I would image that there are others as well.
Cheers,

Take a look at SupportPac website. They have some plug-in nodes with source code in C language.
[Moving to WMQI Forum]

Hi,
Take a look at the v2.1 Programming Guide which describes how to code C plugins. Also, v2.1 has sample code for a message parser and message processing node.
Both v5.0 and v2.1 is supplied with sample C code.

Besides my quesiton for direction for writing Plug-in Node in C...
can I get some clear light in two lines below..
Plug-in nodes, or custom nodes, can be written in C or Java.
Java can only be used to write plug-in processing nodes or input nodes

Thanks!
To answer your questions,
You can write plug-in processing nodes (like MQGet, SendMail, etc) in C or Java language. But, if you are planning to write a plug-in input node then must use Java.

Yes, that's true.
Plug-in parsers - in C only
Plug-in processing nodes - C & Java
Plug-in Input Nodes - Java only
Am I missing anyting?

Now my question has gone back to square one....
This what I read in one of the RedBooks....(sg246579 - Developing Solutions in WebSphere MQ Integrator, chapter#7)
Plug-in nodes, or custom nodes, can be written in C or Java.
Java can only be used to write plug-in processing nodes or input nodes
so.. u think. there cud be a typo the publication.??

Nope! If you re-read the statement 5-10 times, you can see it from a different angle!

As Jeff pointed out, you can write plug-in parsers in C language only. This means, you cannot use Java to write plug-in Parsers.
