hibernate: java.lang.IllegalArgumentException: org.hibernate.QueryException: Unable to resolve path

 >PROBLEM

java.lang.IllegalArgumentException: org.hibernate.QueryException: Unable to resolve path [e.title], unexpected token [e] [select e from br.com.adr.model.entity.security.uni.RoleEntity WHERE e.title = :title]

>SOLUTION

Original code:

String sql = "select e from " + this.entityName + " WHERE e.title = :title";

Query query = em.createQuery(sql, RoleEntity.class);

query.setParameter("title", title);

Fixing the code:

Missing the 'e' entity alias:

String sql = "select e from " + this.entityName + " e WHERE e.title = :title";
