我的WebSphere 8.5应用程序有一个包含MDB项目的EAR项目，该项目构建为生成JAR。该JAR有一个类，它引用来自第三个项目的EAR中的辅助JAR中的类。
包含MDB的jar（ASyncEJB.jar）的清单是
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.2
Class-Path: ASync.jar
lib\aopalliance\aopalliance-1.0.jar
lib\asm\asm-3.1.jar
etc (more lib references)
EAR中包含企业项目的清单看起来像
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.2
Created-By: abc
Built-By: xyz
Built-Date: September 18 2014
Implementation-Version: Value_not_provided
看起来ASyncEJB.jar清单中的类路径应该允许它从辅助ASync.jar加载类。
The structure of the EAR is
lib
META-INF
ASync.jar
ASyncEJB.jar
带有MANIFEST.MF的META-INF文件夹的application.xml看起来像
<?xml version="1.0" encoding="UTF-8"?>
<application id="Application_ID" version="6" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_6.xsd">
<display-name>AsyncEnterprise</display-name>
<module id="Module_1381933529290">
<ejb>ASyncEJB.jar</ejb>
</module>
</application>
为什么我会在ASyncEJB.jar中的类调用的ASync.jar中的类上获得java.lang.ClassNotFoundException？
错误是：
