今天调试项目登录是网页提示session error的错误查了资料才知道是crossDomainSessionSecurity配置的问题。

原web.xml中的dwr配置如下：

<servlet>
    <servlet-name>dwr-invoker</servlet-name>
    <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>activeReverseAjaxEnabled</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>initApplicationScopeCreatorsAtStartup</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>maxWaitAfterWrite</param-name>
      <param-value>500</param-value>
    </init-param>
        
    <load-on-startup>1</load-on-startup>
  </servlet>

修改之后的web.xml中的dwr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>true</param-value>
    </init-param>
    <init-param>
      <param-name>activeReverseAjaxEnabled</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>initApplicationScopeCreatorsAtStartup</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>maxWaitAfterWrite</param-name>
      <param-value>500</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>

新加入了：

 <init-param>  
            <param-name>crossDomainSessionSecurity</param-name>  
            <param-value>false</param-value>  
     </init-param>

在 Direct Web Remoting 2.0中 crossDomainSessionSecurity默认配置是true意思是禁止其他域发送请求。

改为false问题解决。
