jasper ireports concat

[bmccorkle]

Hello,

I am tring to dynamically render 3 jpeg images into an Apex report using ireport and jasper.  I am tring to dynamically create the file name.

Here is what I have so far:  I created the report and added the images to the report, created a parameter for each image.

Now I need to be able to dynamically create the image name because I 25 jpeg images but I only want certain ones that match my varibles.

Now under the parameter for the image in the expression I am tring to create example   "big-blue.jpg"   where big-blue is a varible.

I have tried different ways like   """ + $P{big-blue} + ".jpg" + """  This does not work for me.  I really need the " around the file name..

Thanks in advance..
