The result is that you get a copy of the original object and not the

used to invoke an EJB across a network in a client-server fashion. There
are no restrictions on the Remote interface itself, but there are on the
data passed in and out of the remote interface. The <em>values</em> passed into a
method or returned from a method of a Remote interface <em>must be
-serializable</em>. It is fine for the method signature to be, for e<IMG class="emoticon" src="https://cwiki.apache.org/confluence/images/icons/emoticons/error.gif" height="16" width="16" align="absmiddle" alt="" border="0">ample,

<p>{info:title=JNDI Names}
Note that JNDI names for Java SE clients are not standardized by the EJB
spec. This is unfortunate and something being addressed in EJB 3.1. The
default schema that OpenEJB uses is ejbName + interfaceType (i.e. Local,
-Remote, LocalHome, RemoteHome), so in our e<IMG class="emoticon" src="https://cwiki.apache.org/confluence/images/icons/emoticons/error.gif" height="16" width="16" align="absmiddle" alt="" border="0">ample "CalculatorImpl" +
+Remote, LocalHome, RemoteHome), so in our example "CalculatorImpl" +
"Local" and "CalculatorImpl" + "Remote". You can in fact change this
default to be absolutely <a href="jndi-names.html">anything you want</a>
including interface class name, ejb class name, and more.
