| /** |
| * 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. |
