custom processor libraries?

Is it possible to have specific libraries for a custom processor? More specifically, we have someone trying to write a custom processor to talk to a web service (because constructing the WS XML in XSLT is too fiddly), and a specific version of axis is required which conflicts with the one shipped in Orbeon.

The Axis library in Orbeon Forms is only used by the oxf:delegation
processor. You may be able to drop a new library without any problem at
all, but at worst this should only break oxf:delegation.

You can't have a library which is "private" to a processor. Everything
is loaded by the same class loader.

Ok - perhaps this could be considered a possible desireable feature then? For example, if I need to talk to two different web services using different versions of axis.

Yes, this has been hanging in the air for a very long time. The solution
is very likely OSGi / JSR-291:

http://www.osgi.org/blog/2006/02/jsr-291-dynamic-component-support-for.html

But don't hold your breath about seeing this in Orbeon Forms soon unless
somebody volunteers to implement it ;-)
