                Hi


                I was having the same issue as you and I went through the iText Seam example and found that they have the itext.jar in their build path.  Once I added this to my build path it worked.


                Hope it helps.


                PS : No where did I read that the itext.jar had to be added to the build path.

                    Yes Sheldon is right.I added iText.jar into my build path, it worked.
