how to read and save a server-side pdf with adobe in a client-side web browser ? (plugin, applet / java servlet, …)

Hello,

My need is:

• read a pdf present on a server to display it in a web browser
• the user can add tooltips, change the order of pages, delete pages, ... and changes must be save server side

Currently, I'm using an independent applet that uses a servlet to open a connection between the client and the server.

This allows you to read and save the pdf as a byte stream.

The environment is : intranet, tomcat, java, jsp, internet explorer

Do you know how I can do this with Adobe ? (Plugin, ...)

Thanks
