| /** |
| * This class is used to generate iPlanet Application Server (iAS) 6.0 stubs and |
| * skeletons and build an EJB Jar file. It is designed to be used with the Ant |
| * <code>ejbjar</code> task. If only stubs and skeletons need to be generated |
| * (in other words, if no JAR file needs to be created), refer to the |
| * <code>iplanet-ejbc</code> task and the <code>IPlanetEjbcTask</code> class. |
| * <p> |
| * The following attributes may be specified by the user: |
| * <ul> |
| * <li><i>destdir</i> -- The base directory into which the generated JAR |
| * files will be written. Each JAR file is written |
| * in directories which correspond to their location |
| * within the "descriptordir" namespace. This is a |
| * required attribute. |
| * <li><i>classpath</i> -- The classpath used when generating EJB stubs and |
| * skeletons. This is an optional attribute (if |
| * omitted, the classpath specified in the "ejbjar" |
| * parent task will be used). If specified, the |
| * classpath elements will be prepended to the |
| * classpath specified in the parent "ejbjar" task. |
| * Note that 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. |
| * <li><i>suffix</i> -- String value appended to the JAR filename when |
| * creating each JAR. This attribute is not required |
| * (if omitted, it defaults to ".jar"). |
| * </ul> |
| * <p> |
| * For each EJB descriptor found in the "ejbjar" parent task, this deployment |
| * tool will locate the three classes that comprise the EJB. If these class |
| * files cannot be located in the specified <code>srcdir</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. |
