Here's the updated SPI based on Gavin's clarification and Adrian's suggestion:
/**
| * A container should implement this interface to allow the Web Beans RI to
| * discover the Web Beans to deploy
| *
| * @author Pete Muir
| *
| */
| public interface WebBeanDiscovery
| {
|/**

web-beans.xml files
| */
|public IterableClass? discoverWebBeanClasses();
|
|/**
| * @return A list of all web-beans.xml files in the app classpath
| */
|public IterableURL discoverWebBeansXml();
|
|/**
| * @return A Map of EJB descriptors, keyed by the EJB bean class
| */
|public MapClass?, EjbDescriptor? discoverEjbs();
|
| }
public interface EjbDescriptorT
| {
|/**
| * @return The EJB Bean class
| */
|public ClassT getType();
|
|/**
| * @return The JNDI name under which the EJB is registered
| */
|public String getJndiName();
|
|/**
| * @return The local interfaces of the EJB
| */
|public IteratorClass? getLocalInterfaces();
|
|/**
| * @return The remove methods of the EJB
| */
|public IteratorMethod getRemoveMethods();
|
| }

Basically this is saying, give me all classes from classpath of a deployment which has web-beans.xml file in its metadata path? I don't understand other two restrictions - ejb-jar.xml and Java class.

I don't understand the second restriction great either. Gavin? The third one I think is saying give me all the classes from any shared (lib/) jar that has web-beans.xml in it's metadata path.

He's talking about the spec defined behaviour (although it is not actually recommended that people use it) see the JavaEE5 spec 8.3.1.3.d anonymous wrote : | Another exception to this rule is JAR files located in the library | directory (usually named lib) in the application package. Note that the | presence of component-declaring annotations in shared artifacts, such as | libraries in the library directory and libraries referenced by more than one | module through Class-Path references, can have unintended and | undesirable consequences and is not recommended. | The reason its not recommend is because if you have for example two ejb jars that reference the same helper jar via the manifest they could both get processed for an ejb contained in the helper jar which could in turn lead to the ejb constructed twice and then not able to bind the remote interface to the same jndi name twice. And other similar problems.

Isn't it more scalabe to use
Iterableclass?
which could be a Set but also could be something more performant
if there are a very large number of classes.

Pete, you slightly mangled the quote from the spec by removing it from context :-) What its really saying is that the web bean manager needs to get given: * a list of all web-beans.xml files in the app classpath * a list of all classes in classpath archives with web-beans.xml files * a list of all EJBs in the application, including their JNDI name and component type View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4189459#4189459 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4189459 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
