EJB Deployment Descriptors not deploying to WLS

Question

Hi,
We're using Eclipse 3.4.1 with the OEPE to target WLS 10.3 with Java 6/JEE 1.4 on a Windows XP Professional development machine.
We have an EJB 2.1 project as part of a larger EAR. The beans (all stateless session beans) and associated interfaces and deployment descriptors within are maintained manually for internal reasons; we do not rely on EJBGen or XDoclet or anything like that to manage these. We are NOT using any annotations in these EJBs, as is the default when you create a bean. Instead we rely on weblogic-ejb-jar.xml and ejb-jar.xml.
We're having an issue where deploying to the local Weblogic server instance fails with the following error displaying in the Eclipse console:
<Dec 19, 2008 9:21:13 AM CST> <Warning> <Deployer> <BEA-149004> <Failures were detected while initiating deploy task for application 'xxxxxxx'.>

[EJB:011023]An error occurred while reading the deployment descriptor. The error was:

We DO have multiple beans defined, but it seems that WLS just isn't aware of them due to the lack of a deployment descriptor. It appears that Eclipse/OEPE is not copying the ejb-jar.xml and weblogic-ejb-jar.xml files to the build directory when the project is build:
xxxxxEJB
|-- ejbModule
|.....|-- META-INF
|.....|.....|-- ejb-jar.xml
|.....|.....|-- MANIFEST.MF
|.....|.....|-- weblogic-ejb-jar.xml
|.....|-- com (etc., .java files)
|-- build
......|-- classes
............|-- META-INF
............|......|-- MANIFEST.MF
............|-- com (etc, .class files)
Other notes:
- Cleaning the project does not help.
- Starting a new workspace does not help.
- It works under Eclipse 3.3.2 with the Europa version of OEPE.
- Explicitly exporting an EJB Jar file DOES include the two deployment descriptors (just not deploying to the embedded test server we've defined in our Servers view)
Any ideas? This seems like either a bug in the OEPE, or maybe WTP.

Yes, I have a simple EJB2.1 project with hand-crafted EJB remote/home interfaces/classes and deployment descriptors. Also tried Clean/Rebuild and manually delete
files under /build/classes.
Here are my descriptors files:
ejb-jar.xml
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar id="ejb-jar_ID" version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">
     <display-name>TestEJB</display-name>
<enterprise-beans>
<session>
<display-name>HelloSessioin</display-name>
<ejb-name>HelloSession</ejb-name>
<home>sessions.HelloSessionHome</home>
<remote>sessions.HelloSession</remote>
<ejb-class>sessions.HelloSessionBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
<security-identity>

</security-identity>
</session>

</ejb-jar>
weblogic-ejb-jar.xml

</weblogic-enterprise-bean>
</weblogic-ejb-jar>
Did you check if there is any error/warning in Error Log view?
