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

Question

我有一个运行应用程序，它是基于 Java 1.6 和 Weblogic 10.3.6 构建的。现在我正在迁移到 Java 1.8 和 Weblogic 12cR2 (12.2.1.3)。我有一个构建在 ANT 上并部署在 Weblogic 中的 EAR 文件。

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。 .EAR 文件生成时没有任何错误。现在我试图在我最新的 Weblogic 中部署它，但出现以下错误：

weblogic.application.ModuleException:

我检查了我的代码，我没有使用任何重复的 ejb jndi 参考和所有。检查了我的 weblogic.xml，weblogic-ejb-jar.xml 一切正常。

请帮助我找出在迁移到新的 Weblogic 服务器时遗漏了什么。

另外，我想通知您，在我的本地机器上，旧的和新的 weblogic 服务器都存在。 Java 6 中的旧代码在旧的 weblogic 中运行很好，也通过重新部署进行了测试，一切都很好。它只是在我的新 weblogic 中它不是运行。我已经升级了项目 class-path 中所有必需的 JAR 文件，并使用 Weblogic 12cR2 附带的相同文件。还有什么我想念的吗？请帮忙。

Answer 1

问题已解决。

解释：我的应用程序有多个 JAR 等依赖项。 JAR 依赖项正在从应用程序类路径中读取。因此在所有 JAR 清单文件中都存在相同的名称。

我现在在创建目标期间使用默认应用程序类路径以外的其他类路径：

<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。
