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

问题描述 投票：1回答：1

服务器环境：Weblogic 10.3.6，JDK 1.7

我有一个运行JDK 7的简单工作Java SE客户端应用程序。在客户端我正在做上面提到的资源托管服务器的非常简单的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");
}

我必须将我正在工作的Java SE客户端应用程序从JDK 7升级到JDK 11.服务器环境保持不变。

一旦我将客户端升级到JDK 11，我就会遇到以下错误。这是预期的，因为corba罐已从JDK 11中移出。

将jacorb-omgapi-3.8.jar添加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，并没有提供任何线索。服务器启动并运行，因为我的旧客户端正在运行。

错误就在这一行

InitialContext ic = new InitialContext(t);

问题

  1. 有人有配置吗？知道如何解决这个问题吗？我是否需要添加任何特定版本的corba罐子？
  2. 我认为JNDI查找的标准J2EE功能应该可行。 Weblogic 10.3.6与JDK 11客户端不兼容吗？

任何帮助是极大的赞赏。

没有适用于JDK 11的WebLogic Server的发布版本.WLS 10.3.6甚至没有关闭（它甚至不能在JDK 8上运行）。

最接近的发行版本是WLS 12.2.1.3.0，它几乎在JDK9上工作，但随着JDK 10和JDK 11的后续更改而被打破。

计划在2019年下半年获得在JDK 11上认证的WebLogic Server版本。
