/**
* Compiles EJB stubs and skeletons for the iPlanet Application Server.
* The EJBs to be processed are specified by the EJB 1.1 standard XML
* descriptor, and additional attributes are obtained from the iPlanet Application
* Server-specific XML descriptor. Since the XML descriptors can include
* multiple EJBs, this is a convenient way of specifying many EJBs in a single
* Ant task. The following attributes are allowed:
* <ul>
* <li><i>ejbdescriptor</i> -- Standard EJB 1.1 XML descriptor (typically
* titled "ejb-jar.xml"). This attribute is
* required.
* <li><i>iasdescriptor</i> -- EJB XML descriptor for iPlanet Application
* Server (typically titled "ias-ejb-jar.xml).
* This attribute is required.
* <li><i>dest</i> -- The is the base directory where the RMI stubs and
* skeletons are written. In addition, the class files
* for each bean (home interface, remote interface, and
* EJB implementation) must be found in this directory.
* This attribute is required.
* <li><i>classpath</i> -- The classpath used when generating EJB stubs and
* skeletons. This is an optional attribute (if
* omitted, the classpath specified when Ant was
* started will be used). Nested "classpath"
* elements may also be used.
* <li><i>keepgenerated</i> -- Indicates whether or not the Java source
* files which are generated by ejbc will be
* saved or automatically deleted. If "yes",
* the source files will be retained. This is
* an optional attribute (if omitted, it
* defaults to "no").
* <li><i>debug</i> -- Indicates whether or not the ejbc utility should
* log additional debugging statements to the standard
* output. If "yes", the additional debugging statements
* will be generated (if omitted, it defaults to "no").
* <li><i>iashome</i> -- May be used to specify the "home" directory for
* this iPlanet Application Server installation. This
* is used to find the ejbc utility if it isn't
* included in the user's system path. This is an
* optional attribute (if specified, it should refer
* to the <code>[install-location]/iplanet/ias6/ias
* </code> directory). If omitted, the ejbc utility
* must be on the user's system path.
* </ul>
* <p>
* For each EJB specified, this task will locate the three classes that comprise
* the EJB. If these class files cannot be located in the <code>dest</code>
* directory, the task will fail. The task will also attempt to locate the EJB
* stubs and skeletons in this directory. If found, the timestamps on the
* stubs and skeletons will be checked to ensure they are up to date. Only if
* these files cannot be found or if they are out of date will ejbc be called
* to generate new stubs and skeletons.
