我正在尝试通过 jsp 部署 jnlp jsp 文件如下所示：

<%response.setContentType("application/x-java-jnlp-file");

String merchantId = request.getParameter("merchantId");
String restaurantId = request.getParameter("restaurantId");
System.out.println(merchantId+"::"+restaurantId); %>
<?xml version="1.0" encoding="utf-8"?> 
<jnlp spec="1.0+" codebase="http://menuzapp-dev-2.appspot.com/" >
    <information>
        <title>Menuzapp Printing</title>
        <vendor>YONG MOOK KIM</vendor>
        <homepage href="http://menuzapp-dev-2.appspot.com/" />
        <description>print tickets</description>
    </information>
    <security>
        <all-permissions/>
    </security>
    <resources>
        <j2se version="1.6+" />
        <jar href="PrinterApplication.jar" main="true" />
        <jar href="bluecove-2.1.1-SNAPSHOT.jar"/>
        <jar href="gson-1.6.jar"/>
        <jar href="jackson-core-lgpl-1.7.2.jar"/>
        <jar href="jackson-mapper-lgpl-1.7.4.jar" />
    </resources>
    <application-desc main-class="com.PrinterApp" >
      <argument><% out.print(merchantId); %></argument>
      <argument><% out.print(restaurantId); %></argument>
    </application-desc>
</jnlp>

我已经使用相同的证书认证了所有 jar，当我尝试在本地服务器上运行它时，它成功启动了 jar，但是当我更改服务器 url 时，我得到如下异常：
