Chris,
I am using session attributes
HttpSession session = request.getSession();
setting my attributes in the session and forwarding it to the jsp to display-
session.setAttribute("balent",balent);
RequestDispatcher dispatcher = getServletContext()
.getRequestDispatcher("/Viewdisplay.jsp");
dispatcher.forward(request,
response);
dispatcher.forward(request, response);
Every other data I am collecting displays in the browser. Why not the picture?
<!-- pic = ${pic} -->
The above gives a runtime error
Thanking you.

Try putting this somewhere on your page, outside of your displaytag and then
"View Source" to see what the value actually is:
<!-- pic = ${pic} -->
If you're correct you should see something like:
<!-- pic = menjeans.png -->
But I suspect you won't. For that to work, something has had to initialize the
pic attribute in one of the page, request, session, or application scopes,
which I suspect isn't happening.
Another thing, ${images/pic} is not the same thing as images/${pic}. The first
is looking for an attribute in the above scopes named "images/pic". The second
is going to add the value of the "pic" attribute (from our comment above) to
the static string images/ so in our example, you should end up with
"images/menjeans.png".
But as was said before, this is basic JSP knowledge, not DisplayTag specific.
Maybe someone here can point you at a good beginners JSP list.

Hi,
${pic}
is a DB table attribute which contains the value or string -
menjeans.png
basically a picture string.
cod
<display:column><img src="${images/menjeans.png}"
alt="Picture"></img></display:column>
<display:column><img src="${images/balpic}"
alt="Picture"></img></display:column>
<display:column><img src="images/menjeans.png"
alt="Picture"></img></display:column>
HTML generation -
<td><img src="0" alt="Picture"></img></td>
<td><img src="0" alt="Picture"></img></td>
<td><img src="images/menjeans.png"
alt="Picture"></img></td></tr></tbody></table>
Thanking you.

What is "pic"? Where's it b being set? Is it a column value? When you say,
"it doesn't work", how do you know that? What does the generated HTML look
like (which is to ask, what is the value of ${pic} when JSP expands that
expression)?
What you need to be doing is arranging for the <img> tag to reference a URL
that includes something that your server can use to load the image file.
I seriously doubt there's a displaytag issue here.

<display:column><img src="images/menjeans.png"
alt="Picture"></img></display:column>
Yes it works.
but how do I display an attribute-
<display:column><img src="images/${pic}" alt="Picture"></img></display:column>
Thank you for your quick reply.

Just on a sanity check, does this work:
<display:column><img src="images/menjeans.png"
alt="Picture"></img></display:column>
?

hello everyone,
I have open up this thread again because I've come to a conclusion it's a
displaytag
problem.
I've the string menjeans.png in a DB. This works for me without displaytag.
<%
String pic2="menjeans.png";%>
<img src="images/<%= pic2 %>">
With displaytag -
<display:column><img src="images/<=bpic>" alt="Picture"></img></display:column>
<display:column><img src="images/=bpic" alt="Picture"/></img></display:column>
<display:column><img src="${images/bpic}" alt="Picture"></img></display:column>
<display:column><img src="images/${bpic}" alt="Picture"></img></display:column>
None of the above works. And this -
<display:column><img src="images/<%=balpic%>"
alt="Picture"/></img></display:column>
Can't even ran my application with that.
So what is your suggestions?
I don't want to have to stop using displaytag as the picture display is an
important part of the application.
Thanking you.
regards
eve
