我已經瀏覽了上述主題的所有帖子，但無法解決此問題。情況是這樣的：Tomcat JNDI資源無法訪問
1）我已經定義了一組在CONF資源/ server.xml中（的Tomcat GlobalNamingResources）8.0.20 2）I已經在Tomcat的CONF聲明ResourceLink/context.xml中 3）從Web應用程序中，我得到名稱不受約束的異常。
根據我的理解，在resource.xml中聲明的資源如果映射到ResourceLink中，則可以從上下文訪問，現在爲所有Web應用程序加載conf/context.xml，並且資源應該可用但他們不是。我錯過了什麼。
下面是這些文件：

感謝
Tomcat中任何資源的名稱都以'java：comp'開頭。 – EJP
是的，JNDI解析是initialContext.lookup（「java：comp/env」），然後是context.lookup（「zookeeperHost」） – Ironluca
