第一个DWR程序遇到的问题

 今天在学习DWR时，按着参考文档编写第一个DWR程序，在写完程序后发现报如下异常：

org.directwebremoting.util.CommonsLoggingOutput error严重: A request has been denied as a potential CSRF attack.

解决方案，将web.xml改为： <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>crossDomainSessionSecurity</param-name><param-value>false</param-value></init-param></servlet>

之后，报错:allowScriptTagRemoting is false

将web.xml改为：

<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>crossDomainSessionSecurity</param-name><param-value>false</param-value></init-param><init-param><param-name>allowScriptTagRemoting</param-name><param-value>true</param-value></init-param></servlet>
