java.lang.String cannot be cast error

Question

I have a DAO method:

     Criteria crit = statelessSession.createCriteria(APRecord.class, "apr");
     crit.createAlias("mAId", "mId", Criteria.INNER_JOIN);

     rit.setProjection(Projections.projectionList()
        .add(Projections.groupProperty("pName"), "pName")
        .add(Projections.groupProperty("kNum"), "kNum")
        .add(Projections.countDistinct("agentG"), "count"));

           return crit.scroll(ScrollMode.FORWARD_ONLY);

This returns me an error:

      java.lang.ClassCastException: java.lang.String cannot be cast to test.model.AR.APRecord

Anyone know what the error is? any help appreciated

Please send the full stack strace and also you entire method. What is the return type of your method ? — Razink, Aug 11 '15 at 17:16

I think the problem lies in this line:

Criteria crit = statelessSession.createCriteria(APRecord.class, "apr");

Basically you are trying to cast a string "apr" to APRecord.class

You can find here some examples for criteria usages.
