I had searched by google for long time ,but I can't find any open source or commercial soft for manipulating ppt(Microsoft). tonicpoint seems a good one but I don't know how to purchase that. can anybody help me? Thanks and Regards,Ronald

Tonicpoint is the only java stuff I've ever seen for powerpoint, but I've never used it nor have I have done anything remotely close to Java+PPT. From their site it looks like you can contact them for commercial sales I might be totally off base here, but can your task be accomplished by automating an actual running instance of powerpoint on a windows machine (ie. VBA, OLE automation, etc)? It's brutal, inefficient, requires windows and an license for office, but depending on what you're doing...maybe it is a reasonable approach :-) I seem to remember something about Open office and java. Maybe something in there can let you bake your own ppt files.
