Sorry, pressed &quot;Submit&quot; too quickly.<br />

EJB-QL does not restrict you from only returning collections.

&gt; &nbsp;Should it be java.lang.Double rather than java.util.Double<br />
<br />
That is a very good point!! &nbsp;Well spotted :-)

EJB Query Language

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
