Office Integration!

Team,

I wanted to integrate Office products like word, excel in Web Dynpro and then to publish on portal.

Does any one have step-by-step guide on how to integrate office products using ABAP. Actually I have started using SE80 but I'm getting the error called "Office control must be bound" after activating the Web Dynpro component.

Please forward me step-by-step guide .

Regards,

Amey
