Export problems

How can I Export a blender 3D object to a macromedia product, for publish it on HTML.
I don’t know what format I could use, I tried to use a xtras thing of macromedia to change the obj export of blender to w3d file, and the installer is too much old, I tried to use some scripts to directly change the format, but the script doesn t work aswell.
Please I need help here, I’m making a website with 3D stuffs on it, it’s too much boring to make an animation frame by frame on flash.
Thanks for the help.
