Heraldo,
I have tried querying a postgis layer and it works great.
This is the code that I use:
protected List queryLayerByPoint(int i, pointObj queryPoint) {
List results = new ArrayList();
layerObj layer = map.getLayer(i);
if (layer != null && isVisible(layer)) {
if (log.isDebugEnabled()) {
log.debug("Querying layer: " + layer.getName());
}
if (layer.queryByPoint(map, queryPoint,
mapscript.MS_MULTIPLE, -1) == mapscript.MS_SUCCESS) {
//resultCacheObj resultCache = layer.ggetResultcache();
if (layer.open() == mapscript.MS_SUCCESS) {
//for (int j=0;j<resultCache.getNumresults();j++) {
for (int j = 0; j < layer.getNumResults(); j++) {
if (log.isDebugEnabled())
log.debug("Layer " + layer.getName() + ",
result number:" + j);
resultCacheMemberObj resultMember = layer.getResult(j);
shapeObj shape = new shapeObj(layer.getType());
layer.getShape(shape,
resultMember.getTileindex(), resultMember.getShapeindex());
if (shape != null) {
Map aResult = getResult(shape, layer);
results.add(aResult);
} else {
log.error("Shape " + j + " is null!");
}
}
layer.close();
} else {
log.error("Cannot open layer: " + layer.getName());
}
} else {
log.info("Query on layer " + layer.getName() + " failed.");
}
}
return results;
}
It is different from yours in that I do not fetch results from the
resultCache and I use layer.getShape instead of getFeature.
Let me know if this fixes your problem.
Regards,
Umberto
