How do I configure Struts 2 to return a generated PDF?

<action name="trial_employee" 
        class="parity.action.Tri开发者_StackOverflow社区alPrintEmployeeCopyAction">
  <result>/protected/trial_employee.pdf</result>
</action>

I've got an action class that generates a PDF file for download. How do I configure the action result to return the PDF?

The above doesn't work, it gives me a 404 error because the pdf isn't physically on the drive, it's being generated dynamically.

If it is being generated dynamically you can return it as a stream something like

<result name="pdf  File" type="stream">
<param name="contentType">${contentType}</param>
</result>
