Displaying Photos stored in Oracle in HTML generated by servlet
I am working on a project that queries staff information and photos from our
oracle database and I need to display this information in a web page.
I can query and display the textual data but now I need to add the image
along with the text.
If this is not the right form, please direct my to the most appropriate.
Otherwise, any help will be appreciated.
Thanks
Calvin

I'm not quite sure what you want.
Are you asking if it is possible? Are you looking for a program that does
what you want? Are you looking for code fragments that show the gist of how
to do what you want? Are you concerned with how to get the picture out of
the database or how to display it once you've retrieved it or both?
In a nutshell, it sounds like it ought to be pretty straightforward to do
what you want to do. I've obtained blobs from databases before - but it was
a DB2 or MySQL database, not Oracle - it wasn't too hard. Simply displaying
a JPEG, GIF, or PNG from the filesystem within a servlet is easy. Fetching a
blob from a database and then displaying it might be a little harder; you
may have to put the image in the file system first although, now that I
think about it, the ImageIO classes should be able to grab the photo without
first having to write it to the file system.
Of course, I'm assuming that your program will be written in a recent
version of Java that support ImageIO.
