Method Detail

doInclude

protected void doInclude(java.lang.String uri,
                         boolean flush)
                  throws javax.servlet.ServletException,
                         java.io.IOException
Override the regular forward to use the file in the user's custom layout, if it exists. Replaces pages matching AppUtils.systemLayoutDirectory with the user's custom layout directory. If the resulting page doesn't map to an existing file, uses the original instead.

This same process happens in BaseRequestProcessor to handle forwards coming from the Struts request.

Overrides:
doInclude in class org.apache.struts.tiles.taglib.InsertTag
Parameters:
uri - The page that will be included (as defined in the Tiles definition XML files)
Throws:
javax.servlet.ServletException - - Thrown by call to pageContext.include()
java.io.IOException - - Thrown by call to pageContext.include()
