How to use pdfviewer in liferay portlet to see a pdf
Hi ,
My requirement is to open a pdf document from my local machine hard disk or
from a online available pdf link in my liferay portlet.
I am looking into PDFBox but I am not able to understand how to start. What
APIs I should use to open a pdf document in my portlet.
Can anyone help me with some sample code or directions to use pdfviewer for
opening a pdf in browser.

Re: How to use pdfviewer in liferay portlet to see a pdf
Posted by Sipin Verma <si...@gmail.com>.
I have created a <a> link in my jsp and have called the
<portlet:actionURL/> .
*<a href="<portlet:actionURL/>" > show pdf</a>*
In my processAction() I have kept below code:
*URL url = new URL("http://samplepdf.com/sample.pdf");
PDDocument.load(url);*
It's not showing anything to me after the jsp page is loaded. My doubt is
that after loading the document, how is it shown in jsp? Do we have to use
some tag to show the pdf?
Can you add the missing part in my code or give me a working sample of code
that loads a pdf document and shows in jsp.
Thanks

you have several options:
a) download that file (you can use HttpURLConnection or something else),
store it locally and use PDDocument.load(file)
b) open inputstream from that remote server and use
PDDocument.load(inputstream)
c) use PDDocument.load(url)
actualy this is not matter of pdfbox.

ok. Thanks for your reply.
I have 2 options to read pdf files.
1) from document library
2) from some other server
Suppose I have the pdf download link then how can I feed this link to pdf
box so that it opens it in my portlet page.

Hi Sipin,
portlet is not able to open file from your local machine.
portlet has access to server files only.
so you have to make portlet where user can upload some pdf file, then
portlet can process that file (and then use pdfbox)
