Java jnlp应用程序被安全设置阻止

发布时间：2020-12-14 05:49:29 所属栏目：Java 来源：网络整理
导读：我有一个企业级的 Java应用程序,它有大量的jars,通过jnlp文件下载到客户端的jvm缓存中.当我启动应用程序时,我在Java控制台上得到以下堆栈跟踪： Exception in thread "AWT-EventQueue-1" java.lang.NullPointerExceptionat com.sun.deploy.ui.DialogTemplate

我的JNLP文件像以下一些审查描述：

还要注意,我在更多的信息面板上获得了一些不同的例外细节：

我对java控制面板的安全性没有任何安全限制.中等水平如下：

感谢任何帮助

新编辑：当我尝试从jvm 1.6机器运行这个jnlp时,我得到了更多的说明stacktrace,如下所示：

java.lang.NoClassDefFoundError: javax/ejb/EJBAccessException

解决方法

我通过进入Java控制面板(开始菜单>所有程序> Java>配置Java)并将两个URL添加到安全编辑站点列表来解决这个问题.

http://code.google.com

http://androidscreencast.googlecode.com

对于Mac系统偏好设置> Java的

在哪里添加这些网站

Java控制面板>安全标签>编辑网站列表>添加>申请>好
