这个参数可以根据需要使用多次，但是不能相同。一个使用J2EE的安全机制的例子：<servlet><servlet-name>dwr-user-invoker</servlet-name><servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class><init-param><param-name>config-user</param-name><param-value>WEB-INF/dwr-user.xml</param-value></init-param></servlet><servlet><servlet-name>dwr-admin-invoker</servlet-name><servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class><init-param><param-name>config-admin</param-name><param-value>WEB-INF/dwr-admin.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>dwr-admin-invoker</servlet-name><url-pattern>/dwradmin/*</url-pattern></servlet-mapping><servlet-mapping><servlet-name>dwr-user-invoker</servlet-name><url-pattern>/dwruser/*</url-pattern></servlet-mapping><security-constraint><display-name>dwr-admin</display-name><web-resource-collection><web-resource-name>dwr-admin-collection</web-resource-name><url-pattern>/dwradmin/*</url-pattern></web-resource-collection><auth-constraint><role-name>admin</role-name></auth-constraint></security-constraint><security-constraint><display-name>dwr-user</display-name><web-resource-collection><web-resource-name>dwr-user-collection</web-resource-name><url-pattern>/dwruser/*</url-pattern></web-resource-collection><auth-constraint><role-name>user</role-name></auth-constraint></security-constraint>使用插件(Plug-in)DWR里的很多部件都是可插入的，所以可以通过替换掉DWR的默认实现类来改变其功能。
