Hi Experts,
I am having trouble displaying BLOB data in my page. My requirement is that I
must be able to show some predefined types(PDF, HTML, GIF, JPEG, DOC, XLS) of
BLOB data in my page. This page must have the header of my application. I tried
to use the example given at http://www.irian.at/myfaces/fileupload.jsf. I tried
that example and it seemed to work for Images. But after I incorporated it in
my app, I am getting the exception. Upload works, but problem is with
displaying the content of the BLOB data. We have a field in the table where we
set what type of data is in the BLOB, so I set the ContentType from that.
I am using Myfaces 1.1.5, Tomahawk 1.1.3, Ajax4Jsf 1.1.1. server is WLS8.1 sp6.
I understand that it is a problem with the page encoding/ content type set for
the page.I tried it with UTF-8 and ISO-8859-1, but neither of them worked. Any
help is appreciated. below is my jsp file and the exception I am getting. the
jsp file is included in a tile.
Thanks,
Sushma
