我正在使用以下步骤在服务器端缓存 jsp 页面在服务器端的以下 url 缓存中定义

我在 java 构建路径中有 web-glue.jar，并且在以下步骤中定义了 tld，但是在执行所有步骤后我收到以下错误

java.lang.NullPointerException

那么我该如何解决这个问题，或者请告诉任何其他方式在服务器端缓存jsp

实际上，我正在开发一个 vxml 应用程序，在该应用程序中我动态地从 xml 提供文本，因此我 wabt 在服务器端缓存一些内容

缓存.jsp 页面

<?xml version="1.0" encoding="UTF-8"?>
<vxml version="2.0" application = "eFMS_approot.vxml" xmlns="http://www.w3.org/2001/vxml" xml:lang = "hi-IN">
<%@ taglib uri="Sun ONE Application Server Tags" prefix="mycache" %>

<mycache:cache>

<form id="Dealer_id_mobile_input">


<var name = "choice" />
    <block>
        <assign name = "node_name"  expr = "'DEALER_CALLER ID ENTRY NODE'" />
    </block>

    <!-- Entering the reg id -->
    <field name = "reg_id" type="digits?minlength=6;maxlength=6">
        <property name="termchar" value="*" />

        <prompt xml:lang= "lang_mode+'-IN'">
            <audio src = "../eFMS/audio/enterregidno.wav"  fetchhint="prefetch">
              Please enter your name
            </audio>
        </prompt> 
</field>
</form>
</mycache:cache>
</vxml

谢谢
