Thanks for the help guys.
I've got it all working correctly now. For other people's future reference.
I think this is the page that Igor was referring to which I pretty much
copied : https://cwiki.apache.org/WICKET/uploaddownload.html
I am retrieving the images from a db as a byte array
//heres a simplified version of my code. Hope this helps someone!
//this is the class that serves up the images
public class ImageResource extends DynamicWebResource {
private static final long serialVersionUID = 1L;
public ImageResource() {
super();
}
@Override
protected ResourceState getResourceState() {
ValueMap params = getParameters();
String id = params.getString("id");
if (id.equals("image1")) {
//show image 1
return new ResourceState() {
@Override
public byte[] getData() {
//get the image1 from server....
return image;
}
@Override
public String getContentType() {
return "image/jpeg";
}
}
} else (id.equals("image2")) {
//show image 2
return new ResourceState() {
@Override
public byte[] getData() {
//get the image2 from server....
return image;
}
@Override
public String getContentType() {
return "image/jpeg";
}
}
}
}
}
//this is how I access the image from wicket
add(new Label("profileImage", "") {
private static final long serialVersionUID = 1L;
@Override
protected void onComponentTag(ComponentTag tag) {
ResourceReference imageResource = new
ResourceReference("imageResource");
tag.put("src",
RequestUtils.toAbsolutePath(getRequestCycle().urlFor(imageResource).toString())+"?id=image1");
super.onComponentTag(tag);
}
});
//and this needs to be added to the wicket application init method
getSharedResources().add("imageResource", new ImageResource());
