从 NetBeans 平台客户端应用程序调用 Weblogic EJB 时发生 LinkageError

Question

我在 NetBeans 平台应用程序中遇到以下链接错误，我在该应用程序中调用在 Weblogic 服务器上运行的 EJB。问题似乎是Oracle提供的wlfullclient.jar（Weblogic客户端）和JDK中的rt.jar（尝试使用JDK 6和7）包含一些相同的CORBA包。 wlfullclient.jar 作为包装的 JAR 包含在执行 EJB 调用的模块中。

我编写了一个独立的 Java 程序，它执行相同的操作并且运行良好。

任何帮助将不胜感激。

Answer 1

我设法通过删除 wlfullclient.jar 并将其替换为 Weblogic 应用程序服务器的 /wlserver_10.3/server/lib 目录中包含的最小 wlclient.jar 来解决此问题。我将 wlclient.jar 添加为项目模块之一中的包装 JAR。
