Question

我知道问题可能已经出现过，但是在Java 7u51之后发生了重大变化。由于applet几乎已经死了，我需要将我项目的applet之一转换为可以在客户端机器上启动的JNLP文件。关于如何使用JSP做任何指针？我是否还需要动态签署JNLP和jar？我目前正在研究Java 7u80。

<%@page pageEncoding="UTF-8"%>
<%@page contentType="application/x-java-jnlp-file" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%>
<%@taglib uri="/WEB-INF/security.tld" prefix="sec" %>

<%

response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache");
response.setDateHeader("Expires", -1);
response.setContentType("application/x-java-jnlp-file");


String strFileName = (String) request.getAttribute("FileName");
HttpSession objHttpSession = request.getSession(false);
String strSessionId =    (String)objHttpSession.getAttribute(MWIConstants.SESSION_ID);
            if (!(objHttpSession.getId().equalsIgnoreCase(strSessionId)) || null == objHttpSession.getAttribute(MWIConstants.HELPER))
            {%>
                <logic:redirect forward="LOGIN"/>
            <%}
