Question

我只想在web.xml中添加一个servlet，如下所示：

<servlet>
        <display-name>AxisJMSServlet</display-name>
        <servlet-name>JMSListener</servlet-name>    
        <servlet-class>com.sinosoft.prpall.web.jms.JMSListenServlet</servlet-class>
        <load-on-startup>110</load-on-startup>
  </servlet>

一切都很好，当我开始我的节目时，我得到了这个：

有人能告诉我发生了什么吗？

你正在尝试创建一个InitialContext，但没有为它提供适当的参数。以下是在Weblogic上创建InitialContext的示例：

http://docs.oracle.com/cd/E15051_01/wls/docs103/javadocs/weblogic/jndi/WLInitialContextFactory.html

如果您没有手动创建InitialContext，则需要从管理控制台配置JNDI设置。

我有这个错误：无法使用哈希表中指定的工厂创建InitialContext
