The default name of the bean is "myBean" according to the WebBeans
specification, so try using:
<?php
echo java_bean("myBean");
?>
You can override the default name with @Named("my-name") as a class
annotation.
Also, if you turn on "fine" logging, you should see the bean get
registered in the logs, and it should show the name that Resin's
assigned.
