public class PlainTextResult

A result that send the content out as plain text. Useful typically when needed to display the raw content of a JSP or Html file for example.

• location (default) = location of the file (jsp/html) to be displayed as plain text.
• charSet (optional) = character set to be used. This character set will be used to set the response type (eg. Content-Type=text/plain; charset=UTF-8) and when reading using a Reader. Some example of charSet would be UTF-8, ISO-8859-1 etc.

 

 <action name="displayJspRawContent" >
   <result type="plainText">/myJspFile.jsp</result>
 </action>


 <action name="displayJspRawContent" >
   <result type="plainText">
      <param name="location">/myJspFile.jsp</param>
      <param name="charSet">UTF-8</param>
