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

The following works for me...

 

<display:column headerClass="data" class="data_left_centered" title="State Emp." sortable="true">

      <img src="images/check.gif"/>

</display:column>

 

So put the image name and path in a request variable, and it should work.

 

<display:column headerClass="data" class="data_left_centered" title="State Emp." sortable="true">

      <img src="${path_to_image}"/>

</display:column>

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.

Hello Paul,
 
 <display:column><img src="${images/pic}" alt="Picture"></img></display:column>
 
pic is a the DB attribute.  IT should work but no.
 
<display:column><img src="images/menjeans.png" alt="Picture"></img></display:column>
 
THe above works though in the DB 'pic' attribute contains the string menjeans.png
 
So That's why I need to display it as the first line above..
 
Basically, if I have 1000 pictures to display I wouldn't want to hard code it as
 
<display:column><img src="images/menjeans.png" alt="Picture"></img></display:column>
 
Thanking you.

What does your <display:table> tag look like?  Does it have an "id" attribute?

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.

I've the string menjeans.png in a DB.  This works for me without displaytag.
 
               <%

None of the above works. And this -

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

Thanking you.

Hi,
 
I am invoking  an entity which takes data from the database and
displays it to the user.  I invoke in a servlet and the servlet forwards
data to the jsp to display.
 
That's I use displaytag
 
servlet-
 
 
try{
                 //call the allitems method
                 balent=balBeanRemote.findAllBals();
                  HttpSession session = request.getSession();
                  session.setAttribute("balent",balent);
                  RequestDispatcher dispatcher = getServletContext()
                                               .getRequestDispatcher("/Viewdisplay.jsp");
                                               dispatcher.forward(request, response);
                                //forward data to the Viewdisplay.jsp to present
                                //it to user
                                  dispatcher.forward(request, response);
             }
            catch(Exception ex){
   System.err.println("Can not show the all bale page");
   }
            }
    
 
jsp -
 
<display:table name="sessionScope.balent" uid="datum" defaultsort="1" defaultorder="descending" pagesize="7" class="tabledata">

What does your <display:table> tag look like?  Does it have an "id" attribute?

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.

Subject: Re: [displaytag-user] displaying images with displaytag issues

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>

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.

Hi,
 
I get this with:-
 
 
<td>menjeans.png</td>
 
with this-
 
 <display:column property="pic" title="should be picture"/>
 
and I get this with -
 
 <!-- pic =  -->
 
with this-
 
<!-- pic = ${pic} -->
 
So the displaytag one above displays the string from my database.
I need to turn that string into a picture.
 
Thanking you.

You can't just reference "pic" like that.

Give your <display:table> tag an attribute like this:  id="row"

Then, instead of ${pic}, use ${row.pic}.

You can't just reference "pic" like that.

Give your <display:table> tag an attribute like this:  id="row"

Then, instead of ${pic}, use ${row.pic}.

Well the table has no data in it at all!  That's what the message, "No
data found to display" means.

Try just using "bent" for your table name (though it depends on what
JSP container you're using).

Hello,
 
I went back to my JSTL code and everything works.  Unfortunately, I have had to
give up on display tag for now.
 
Thanking you all.
