Digital Sign

Hello everybody!

I want to digital sign a PDF document generated with BIRT.

My point is to do it with the user's certificate once the document has been rendered.

How could i do it?

Thanks a lot!!

Hi mdelapenya,

Can you explain more about what you're wanting to do? Thanks.

Hello mwilliams, i'll explain the process:

The framework: Struts-Portlet with Liferay.

After processing an user's request, i serve a PDF generated with BIRT to the user. Next, the user should sign it digitally with his-her digital certificate if appropriate.

I use a struts-action to process user's requests, then i use a BIRT-servlet to serve the PDF to an iframe included in a JSP.

The question is, where can i get the bytes to add the sign after all?

I hope i've explained the situation properly.

Many thanks!!

mdelapenya,

I believe BIRT can write the PDF file to an outputstream instead of the browser, then you can do whatever you want with the bytes.

An example writing a PDF to an outputstream can be seen on another post at <a class='bbc_url' href='http://www.birt-exchange.org/forum/eclipse-birt-newsgroup-mirror/9822-embed-javascript-pdf.html'>http://www.birt-exchange.org/forum/eclipse-birt-newsgroup-mirror/9822-embed-javascript-pdf.html</a>
