dwr遇到这种错误：
org.directwebremoting.util.CommonsLoggingOutput error
严重: A request has been denied as a potential CSRF attack.
在参照dwr的官方网站时，如果在后台出现如下的提示信息：A request has been denied as a potential CSRF attack

则，需要在web.xml中的如下配置修改一下

xml 代码
<servlet> 
    <servlet-name>dwr-invokerservlet-name> 
    <servlet-class>uk.ltd.getahead.dwr.DWRServletservlet-class> 
    <init-param> 
        <param-name>debugparam-name> 
        <param-value>trueparam-value> 
    init-param> 
servlet> 
修改为：

xml 代码
<servlet> 
    <servlet-name>dwr-invokerservlet-name> 
    <servlet-class>uk.ltd.getahead.dwr.DWRServletservlet-class> 
    <init-param> 
        <param-name>debugparam-name> 
        <param-value>trueparam-value> 
    init-param> 
    <init-param> 
        <param-name>crossDomainSessionSecurityparam-name> 
        <param-value>falseparam-value> 
    init-param> 
  servlet> 
即加入了跨域调用功能



报错:allowScriptTagRemoting is false

在WEB.xml中加入:

<init-param>
<param-name>allowScriptTagRemoting</param-name>
<param-value>true</param-value>
</init-param>
