That may be wrong, the various Writer/Calc/Impress pdf import really
just handles hybrid pdf (so later it can do an ODF import), nothing
else. Only Draw does pdf import.

If you only need to handle ODF documents, there is a thumbnail in these
documents, so providing preview for them is quite easy. For random
formats, I think you have to be more creative: e.g. convert to ODF
(that's always a good idea) and extract the thumbnail, or just convert
to PDF, and then convert to PDF to some image. It's up to you.

If you want to do document conversion from Tomcat, I would check how the
existing jodconverter-tomcat project does it, it should save you quite
some time, unless you like experimenting. :-)

HTH,
