I have a strange problem. I saw some topics in forum about that but it doesn't solve my problem. I'm trying to use mediaOutput to output images from database.
My jsf is
<ui:repeat value="#{map.coordinates}" var="coord">
<a:mediaOutput element="img" cacheable="true" createContent="#{map.paint}" value="#{coord}" mimeType="image/gif" />
</ui:repeat>And my bean is
public List<Node.Coorinates> getCoordinates(){
List<Node.Coorinates> result = new LinkedList<Node.Coorinates>();
result.add( new Node.Coorinates( 1, 1 ) );
result.add( new Node.Coorinates( 1, 2 ) );
result.add( new Node.Coorinates( 1, 3 ) );
return result;
}the paint code
public void paint(OutputStream out, Object data) throws IOException {
log.info("start of paint");
if ( data instanceof Node.Coorinates ){
Node.Coorinates coords = (Node.Coorinates)data;
Node node = nodeDAO.findNodeByCoordinates( coords );
MapImage mapImage = (MapImage)node.getImage();
out.write(mapImage.getImage());
}
}Node.Coordinates is a very simple object just with 2 feilds. it implements Serializable.
When cacheable="true" cache doesn't work - I get red squares (empty reply from server). Without cache everything is ok. Maybe I should use paint2d for that?
