overlay images retrieved from a Database
Hi there, I have a image of a map and want to overlay a set of images with x
y coords from a database.
This is my code which does not work!
img:image
src=/images/map_01.gif
dir=generated
name=map_rendered.jpg
attributes=alt='A sample image'
refresh=true
quality=1.0
img:resize scale=100% /
!--load all points to map --
c:forEach var=poimaps
items=${requestScope.poimaps}
img:overlay x=${poimaps.x_id}
y=${poimpas.y_id} color=0xff tolerance=35
img:image
src=/images/${poimaps.imageName}.gif /img:image
/img:overlay
/c:forEach
/img:image
This is the error message!
javax.servlet.ServletException: Overlay must be a nested tag of Image Tag!
Help would be appreciated

Re: overlay images retrieved from a Database
For better or worse, img:overlay appears to require that it's
parent tag (not just an ancestor) be an instance of
org.apache.taglibs.image.ImageHolder. In your case, c:forEach is the
parent tag so the exception gets thrown.

Re: overlay images retrieved from a Database
Thanks Kris, got the what you are saying can't find any samples for what
I am looking for. Doesn't anyone use the image tag lib to generate on the
fly overlayed images?
