SimpleJPAQuery

Now instead of creating named queries, or writing down your queries in JPA, all you need is to fill a bean of the JPA class you want to query and call the "findByExample" method, and it will filter accordingly. You can also customize how the query is built by some annotations that can be added to the JPA class (@Exact for exact string instead of using like, @Exclude to exclude fields or a value for this field, @From and @To for date ranges... and more).
