jndi - 从 JDK 11 客户端到 Weblogic 10.3.6 (JDK 7) 服务器的简单 JNDI 查找不起作用

Question

服务器环境:Weblogic 10.3.6、JDK 1.7

我有一个使用 JDK 7 运行的简单 Java SE 客户端应用程序。在客户端，我正在对上面提到的资源托管服务器进行非常简单的 JNDI 外观。

ClassPath 中的 jar : wlthint3client.jar

public static void main(String[] args) throws Exception {
    Hashtable t = new Hashtable();
    t.put(InitialContext.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
    t.put(InitialContext.PROVIDER_URL, "t3://localhost:7003/");
    InitialContext ic = new InitialContext(t);

    String jndiName = "weblogic.jdbc.DataSource.Workflow";

    Object obj = ic.lookup(jndiName);
    System.out.println("Found it");
}

我必须升级我的工作 Java SE 客户端应用程序从 JDK 7 到 JDK 11。服务器环境保持不变。

当我将客户端升级到 JDK 11 时，我遇到了以下错误。这是预期的，因为 corba jar 已从 JDK 11 中移出。

Exception in thread "main" java.lang.NoClassDefFoundError: org/omg/CORBA/SystemException

添加 jacorb-omgapi-3.8.jar 到客户端类路径以修复上述异常。

在此之后，我遇到了超时异常并且没有给出任何线索。服务器已启动并正在运行，因为我的旧客户端正在运行。

错误在这一行

InitialContext ic = new InitialContext(t);

问题

1. 有没有人使用配置？任何想法如何解决这个问题？我是否需要添加任何特定版本的 corba jar？
2. 我认为 JNDI 查找的标准 J2EE 功能应该可以工作。 Weblogic 10.3.6 与 JDK 11 客户端不兼容吗？

非常感谢任何帮助。

没有可在 JDK 11 上运行的 WebLogic Server 发布版本。WLS 10.3.6 甚至还没有接近(它甚至在 JDK 8 上都不起作用)。

最接近的发布版本是 WLS 12.2.1.3.0，它在 JDK9 上几乎可以工作，但随着 JDK 10 和 JDK 11 的后续更改而被破坏。

计划在 2019 年下半年推出通过 JDK 11 认证的 WebLogic Server 版本。
