How to get ResultSetMetaData from enity manager?

Given a simple table (开发者_运维百科example_table) with the following columns: id, first_name, last_name is it possible, by executing a JPA native sql query em.createNativeQuery("select * from example_table") retrieve the column names as well as the data? Running the getResultList() on the query only returns the data. How else can I retrieve the column names?
