how to deal with the Frame when using sitemesh

1. install the sitemesh described in the above article.

2. To be able to specify which mappers will be applied to a request, create the file [web-app]/WEB-INF/sitemesh.xml that contains the following:

   <sitemesh>
       <property name="decorators-file" value="/WEB-INF/decorators.xml" />
       <excludes file="${decorators-file}" />
   
       <page-parsers>
           <parser content-type="text/html"
               class="com.opensymphony.module.sitemesh.parser.FastPageParser" />
           <parser content-type="text/html;charset=ISO-8859-1"
               class="com.opensymphony.module.sitemesh.parser.FastPageParser" />
       </page-parsers>
   
       <decorator-mappers>
           <mapper class="com.opensymphony.module.sitemesh.mapper.ConfigDecoratorMapper">
               <param name="config" value="${decorators-file}" />
           </mapper>
       </decorator-mappers>
   </sitemesh>
   

   in this example, the only mapper that will be applied is the ConfigDecoratorMapper, and that will only be applied to responses of type text/html or text/html;charset=ISO-8859-1. Responses of any other content type (eg image/gif) will be ignored by Sitemesh. Additionally, any files that match a pattern specified in the excludes file (in this case '/WEB-INF/decorators.xml') will not be touched by Sitemesh.

3. The excludes file points to an XML file that contains an <excludes /> block similar to the following: add the following code in your decorators.xml

   <decorators defaultdir="/decorators">
    <excludes>
     <pattern>/plainPage.jsp</pattern>
     <pattern>/ewebeditor/*.*</pattern>
    </excludes>
    <decorator name="main" page="main.jsp">
     <pattern>/*</pattern>
    </decorator>
   </decorators>
