Using 20.5 and Trunk in same project?
Hi all,
we've a project in which fop20.5 is already working for many year. now
we wants to add some new features and are not sure if it is possible to
use 20.5 and the trunk version in the same application.
all jars are in the same classpath....
has someone some experience with this?
we don't want to port the 20.5 yet..
Thanks
Dirk

Yes, I do have experience with that. I've written a wrapper API for
XSL-FO implementations [1] where I support exactly that: Support
multiple FO implementations in the same VM. For that to work you have to
isolate the two versions using different class loaders. FOP Trunk still
uses the same package names as 0.20.5 so you can't have both in the same
classpath. The problem with [1] is that it's currently a little behind.
If you want to use it with the latest FOP release I'd have to update it
first. And I'm still looking for a better name for that thing. Sun
doesn't like my using "JAXG". :-( You can also just look at the source
code to get some ideas how to isolate the FOP versions.
