NullPointerException Using QueryBuilder is JAVA USe API extending WCMUSePojo

Question

Hi All,

I am getting NullPointerException at --> Query query = builder.createQuery(PredicateGroup.create(map), session);

I have used -->

@Reference
private QueryBuilder builder ; before (Outside) activate method.

Code Snip:::

Map<String, Object> map = new HashMap<String, Object>();
       map.put("type", "cq:Page");
       map.put("path", roothPath);
       map.put("1_property", "=@jcr:content/someprop");
       map.put("1_property.value", "somevalue");
       map.put("1_property.operation", "like");
       map.put("orderby", "@jcr:content/jcr:lastmodified");
       map.put("orderby.sort", "desc");
       map.put("p.limit", "-1");
    Query query = builder.createQuery(PredicateGroup.create(map), session);

       SearchResult result = query.getResult();

Can anyone suggest where am i missing this.

Thanks,

Raghava.

Got My Mistake,@Override public void activate() throws Exception {  resolver = getResourceResolver();  session = resolver.adaptTo(Session.class);  builder = getSlingScriptHelper().getService(QueryBuilder.class); instead of reference }

Other possibility is to use Sling-Models, then you can use the @Inject annotation.
