从10.3.6升级到Weblogic 12cR2后，由于NameAlreadyBoundException而导致Weblogic部署问题

Question

我有一个基于Java 1.6和Weblogic 10.3.6的运行应用程序。现在我正在迁移到Java 1.8和Weblogic 12cR2（12.2.1.3）。我有一个EAR文件，它构建在ANT上，部署在Weblogic中。

我已经在我的系统中安装了JDK 1.8和Weblogic 12cR2。我已经编译了我的代码库，并成功地在ANT上构建了它。生成的EAR文件没有任何错误。现在，我正试图在我最新的Weblogic中部署它，我得到了以下错误：

weblogic.application.ModuleException: 
Unable to bind Business Interface to the JNDI name: myapp_admin_ejb_jarAdminServiceBean_Home, 
throw exception javax.naming.NameAlreadyBoundException: [EJB:011224]Unable to bind the interface com.abc.xyz.admin.ejb.session.AdminServiceRemote to remote. 
Another EJB has already bound an interface to that name.; 
remaining name 'ejb/admin_service_jndi'. 
NestedException Message is :

我已经检查了我的代码，我没有使用任何重复的ejb jndi引用等等。检查了我的weblogic.xml，weblogic-ejb-jar.xml一切都很好。

请帮助我找出在迁移到新的Weblogic服务器时遗漏了什么。

另外，我想通知大家，在我的本地机器中，新旧weblogic服务器都存在。Java 6中的旧代码在旧weblogic中运行良好，经过重新部署测试，一切正常。它只是在我的新weblogic中，没有运行。我已经升级了项目类路径中所有必需的JAR文件，并使用了Weblogic 12cR2附带的JAR文件。还有什么我遗漏的吗。请帮忙。

问题已解决。

说明：我的应用程序有多个JAR和依赖项。JAR依赖项是从应用程序类路径中读取的。所以在所有JAR清单文件中都有相同的名称。

在目标创建过程中，我现在使用的是除默认应用程序类路径之外的其他类路径：

<path id="mf.classpath">    
    <path refid="common.classpath" />
    <fileset dir="${dist.dir}" includes="/**/*.jar" excludes="/**/*ejb*"/>
</path>

这解决了我的问题。
