I'm reading about the packaging rules for creating an ejb-jar.jar file, and I'm wondering whether it's possible to include a jar file (containing helper classes) inside of the ejb-jar file. A "lib" dir (for containing such helper jars) doesn't seem to be part of the ejb-jar file format.
The EJB 3 spec has this to say (Ch 20, "Enterprise JavaBeans 3.0, Final Release): "The ejb-jar file must also contain, either by inclusion or by reference, the class files for all the classes and interfaces that each enterprise bean class and the home interfaces, component interfaces, and/or web service endpoints depend on, except Java EE and J2SE classes. This includes their superclasses and superinterfaces, dependent classes, and the classes and interfaces used as method parameters, results, and exceptions"
Now, it seems that the root of the the ejb-jar file contains all the classes (in the appropriate Java package layout). But what about including JAR files? The ejb-jar spec seems to have nothing to say about a "lib" dir that can contain jars (as a WAR file can).
Summary of questions: 1) Can an ejb-jar file contain a jar file? If so, how/where? 2) Can the ejb-jar file's META-INF/MANIFEST.MF file contain a reference to a JAR file?
I'm not considering correct design at the point... I'd just like to know if these 2 scenarios are possible.
"Note : The Class-Path header points to classes or JAR files on the local network, not JAR files within the JAR file or classes accessible over internet protocols. To load classes in JAR files within a JAR file into the class path, you must write custom code to load those classes. For example, if MyJar.jar contains another JAR file called MyUtils.jar, you cannot use the Class-Path header in MyJar.jar's manifest to load classes in MyUtils.jar into the class path. "
