Hey guys,
There is main issue with our poi bundle. It does not contain poi-ooxml-schemas
artifact which contains stuff necessary for docx and office 2007 stuff. I've
tried to update this bundle to have ooxml-schemas embedded as well, but then
I've hit another issue which prevented me from reading docx contents. I don't
know details of xmlbeans (and honestly I won't go into detail), but it uses
some weird constructions to register generated code in schema registry (below)
causing errors (at the end). The workaround to make everything working smoothly
is to embed xmlbeans together with poi. I prepared a new version of poi 3.9
bundle which wraps xmlbeans 2.3 used by this version of poi. The big question
is how we can solve this to let our bundle users work with it. There are couple
of posts about these issues, so do you accept workaround solution? :) I'm not
sure what's going on with poi and xmlbeans, however maybe some of you can make
pressure on them as we did with wicket to avoid split packages and so on?
