Here's an untested idea. What if you use a proxy tag to satisfy overlay's parenting constraints? You'd do something like:
<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="${requestScope.poimaps}"> <imgHelper:proxy> <img:overlay x="${poimaps.x_id}" y="${poimpas.y_id}" color="0xffffff" tolerance="35"> <img:image src="/images/${poimaps.imageName}.gif"/> </img:overlay> <imgHelper:proxy> </c:forEach> </img:image> Here's the code for the proxy tag: package com.directthought.taglibs.image; import com.mullassery.imaging.Imaging; import java.awt.image.BufferedImage; import javax.servlet.jsp.JspException; import javax.servlet.jsp.tagext.BodyTagSupport; import javax.servlet.jsp.tagext.TryCatchFinally; import org.apache.taglibs.image.ImageHolder; public class ProxyTag extends BodyTagSupport implements TryCatchFinally, ImageHolder { private ImageHolder ancestor; public ProxyTag() { super(); } public int doStartTag() throws JspException { this.ancestor = (ImageHolder)findAncestorWithClass(this, ImageHolder.class); if (this.ancestor == null) { throw new JspException("ProxyTag could not find an ImageHolder ancestor"); } return EVAL_BODY_BUFFERED; } public void doCatch(Throwable t) { // no-op } public void doFinally() { this.ancestor = null; } public BufferedImage getImage() { return this.ancestor.getImage(); } public void setImage(BufferedImage image) { this.ancestor.setImage(image); } public Imaging getImaging() { return this.ancestor.getImaging(); } } On 10/22/07, Kris Schneider <[EMAIL PROTECTED]> wrote: > Hang on, I've got an idea that might work.
