I got stuck with this one...I followed your instruction but i dont know how
to integrate in the last part. This is to be rendered in web page. In pages
1 and 2, im successful in storing the pdf in memory but the last page which
contains overflow String, I cant write the columnText to writer. Could you
guide how to do it? Below is my code.
// TODO Auto-generated method stub
/*
* Set HTTP Content Type

response.setContentType("application/pdf");
//response.addHeader("Pragma", "public");
//response.addHeader("Cache-Control", "max-age=0");

filename=\"sarFormDI.pdf\"");
/*
* If User clicked on the Save button, force the browser to open a
Save As dialog.
*/

response.setHeader("Content-Disposition", " attachment;
filename=\"sarFormDI.pdf\"");
