Your configuration is okay but you have misused the action tag. You
can't embed an inline image within an HTML page.
ie. you've started sending a result, which is from JSP, and then
part-way though you've attempted to output some binary data in the same
output stream.
You do not need special tags. As Gabriel suggested, you simple need an
image tag.
default.jsp:
<p>The image follows</p>
<img src="pgetpicture.action" alt="generated image"/>
That means there's first an HTML stream (from the JSP), then separately
browser opens the image stream from your action.
Hope that makes sense.

I'm sorry again.
The mailing list manager does not allow attached files.
But the problem is still the same.
I get the image from DB, but I see binary characters and not the image.
Probably I have to use some special tags but I cannot understand what.
Thanks.

I'm sorry, I intend "mistake", writing the modules, not "error".
The image is stored in an Oracle DB, not in a file system.
I get the BLOB from DB, but when I try to view the image what I see
is in the file attached to this mail.
I see binary characters and not the image.
Thanks.

Please post the error (stack trace?).
I suppose that if you want to "show" the image, you need some <img>
tag in your html page result. <s:action> tag doesn't generate <img>
tags for you AFAIK.

Hello,
I have a web application that must get image from blob field stored
