Hi folks,
I have these classes:
package com.myapp;
public class Minerals extends WebPage{
public Minerals(){
RepeatingView repeater = new RepeatingView("repeater");
//data from database - images and descriptions
ArrayList dataFromDB = (new ImagesMinerals()).load();
//descriptions
ArrayList desc = new ArrayList();
desc = (ArrayList) dataFromDB.get(0);
//images
ArrayList images = new ArrayList();
images = (ArrayList) dataFromDB.get(1);
int size = images.size();
for(int i = 0; i < size; i++){
String repeaterID = repeater.newChildId();
ImageRepeater repeaterChild = new
ImageRepeater(repeaterID);
//add description
repeaterChild.add(new Label("description", (String)
desc.get(i)));
//add image
DBImage image = new DBImage();
image.setImageData((byte[]) images.get(i));
//not caching on browser
Double random = Math.random();
//put shared resource (image) on clean path
Start.get().getSharedResources().add("image" +
random.toString() + ".jpg", image);
ResourceReference imageResource = new
ResourceReference("image" + random.toString() + ".jpg");
String url =
RequestCycle.get().urlFor(imageResource).toString();
//href in <a> and src in <img> should have same path
because lightbox won't work...
ExternalLink odkaz = new ExternalLink("anchor",
url);
WebMarkupContainer imageSrcAttribute = new
WebMarkupContainer("image");
imageSrcAttribute.add(new AttributeModifier("src",
new Model<String>(url)));
odkaz.add(imageSrcAttribute);
odkaz.add(new SimpleAttributeModifier("title",
(String) desc.get(i)));
repeaterChild.add(odkaz);
repeater.add(repeaterChild);
}
this.add(repeater);
}
}
package com.myapp;
public class ImagesMinerals extends
LoadableDetachableModel<ArrayList<byte[]>>{
@Override
protected ArrayList load(){
DBGetImages databaseMinerals = new DBGetImages();
ArrayList dataMineraly = databaseMinerals.getData();
return dataMinerals;
}
}
My problem is that when i again and again click on page the memory in tomcat
is eaten and I end-up with
Java heap space error. Doesn't matter if heap is 64MB or 1GB on start, after
some clicks memory is eaten.
Somethink wrong with my LDM?
