Jakarta ee 无法解决<；JNDI>；

我在JNDI中有一个SessionBean绑定在“ejb.Bb\u restriction\u USRemoteHome”下。Weblogic控制台也证实了这一点

但在通过以下代码访问它时：

private static Context getInitialContext() throws NamingException {
      Context ctx = null;
      Hashtable ht = new Hashtable();
      ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
      ht.put(Context.PROVIDER_URL, "t3://localhost:7001");
      ctx = new InitialContext(ht);
      return ctx;
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    try {
        Context ctx = getInitialContext();
        System.out.println(ctx.list("java:comp/env"));
        System.out.println(ctx.lookup("ejb.Bb_restriction_USRemoteHome").getClass());
    } catch (NamingException e) {
        e.printStackTrace();
    }
}

，我得到了以下错误：

“System.out.println（ctx.list（“java:comp/env”）；”的输出是weblogic.jndi.internal。NameClassPairEnumeration@aee30f只是

有谁能告诉我如何检索JNDI名称为“ejb.Bb\u restriction\u USRemoteHome”的对象吗？

您正在尝试在全局JNDI上下文中访问JNDI名称“ejb.Bb\u restriction\u USRemoteHome”。显然，容器可以解析ejb部分，但不能解析“Bb_restriction_USRemoteHome”，因此名称显然不正确

您可以尝试简单地列出ejb上下文的内容，然后从那里开始工作

为此，请使用以下方法：

NamingEnumeration namingEnumeration = ctx.list("ejb");
while (namingEnumeration.hasMoreElements()) {
    NameClassPair entry = (NameClassPair) namingEnumeration.nextElement();
    System.out.println(entry.getName());
}

您可以显示会话bean的

ejbjar.xml

条目吗？
