Power point presentation using java

hi all,

I am developing a web application for e-learning. I have a problem. I am very new to all this stuff. I want to allow a user to upload a power point presentation and this should be visible to all as one slide after the other by clicking next. Please help me with any example source code or an example.

Any help would be highly appreciated.

Thanks in advance,

Regards,
