Oracle GlassFish Server 3.0.1 Application Development Guide

Example 2

This query returns all products in a specified price range. It defines two query parameters which are the lower and upper bound for the price: double low, double high. The filter compares the query parameters with the price field:

low < price && price < high

Query ordering is set to price ascending.

The finder element of the sun-ejb-jar.xml file looks like this:

   <query-params>double low, double high</query-params>
   <query-filter>low &lt; price &amp;&amp; price &lt high</query-filter>
   <query-ordering>price ascending</query-ordering>
