Hi All, Thank you so much for the many replies. Tried out the solution and library suggested by Xi just now, since his solution was the easiest to verify. It works.
After having downloaded this library: http://sourceforge.net/projects/migbase64/ I convert the byte string like this: String base64String = "data:image/png;base64," + Base64.encodeToString(image,false); Then simply use it at the client side like this: Image image = new Image(base64String); The image now displays. I think the base64 library I initially used was not browser safe as Jens and Thad suggested. Would have build a servlet as Jens suggested if it had not worked. As for your question Alexandre, I don't know why the service developer suggested I could not use base64. Could have been inexperience on his behalf :-). Clearly base64 does work.
