Struts PDF Generating Example

To generate a PDF in struts you need to use struts stream result type as follows

<result name="success" type="stream">
	<param name="contentType">image/jpeg</param>
	<param name="inputName">fileStream</param>
	<param name="contentDisposition">attachment;filename="document.pdf"</param>
	<param name="bufferSize">1024</param>
</result>
