I have exactly the same problem... any clue ?

I finally solved this using Strings encoded with BASE64Encoder.

Hmm...

Can you change this type to built-in WebDynpro type <b>binary</b> that corresponds to byte[]?

Hi VS,

I think I haven't explained it clearly.

I have used the file upload component to get the data from a file.. and of course with a context attribute of binary type. I have to assign this byte[] to the web service model method parameter. But to my fascination, the webdynpro application crashes on start throwing the above mentioned exception.

Any Idea??

thanks
