Eclipselink seems to have an extension in place there. Here is the javadoc for that method: {code} /** * Create an instance of <code>TypedQuery</code> for executing a * Java Persistence query language statement. * The select list of the query must contain only a single * item, which must be assignable to the type specified by * the <code>resultClass</code> argument. * @param qlString a Java Persistence query string * @param resultClass the type of the query result * @return the new query instance * @throws IllegalArgumentException if the query string is found * to be invalid or if the query result is found to * not be assignable to the specified type * @since Java Persistence 2.0 */ public <T> TypedQuery<T> createQuery(String qlString, Class<T> resultClass); {code} Notice specifically... {quote} The select list of the query must contain only a single item, which must be assignable to the type specified by the <code>resultClass</code> argument {quote} -- This message was sent by Atlassian JIRA (v6.4.11#64026)
