User-defined function in multiple Message Mappings

Hi,

I have created a user defined function in a message

mapping, and the same functionality is required in

multiple message mapping within the namespace or outside

the namespace. How can I use it ?

If I import it as a JAR Archive than too, I need to

import this class in the every user deined function

where I want to use this functionality.

That way I can copy that code also instead of importing

the archive.

Is there any other way through which I can use one of

my user defined function in multiple maps ???

Thanks,

Vijay
