DWR出现session error解决方法
今天在使用dwr的时候遇到了session error 错误。解决方法是在web.xml 中添加如下配置

<servlet>   <servlet-name>dwr-invoker</servlet-name>   <servlet-class>    org.directwebremoting.servlet.DwrServlet   </servlet-class>   <init-param>    <param-name>debug</param-name>    <param-value>false</param-value>   </init-param>   <init-param>    <param-name>logLevel</param-name>    <param-value>warn</param-value>   </init-param>   <init-param>    <param-name>crossDomainSessionSecurity</param-name>    <param-value>false</param-value>   </init-param   <load-on-startup>1</load-on-startup></servlet>
