PDF handling

Read and open the PDF in a new browser window

The goal is to use JSF to open a PDF file inline in a new browser window without showing the full PDF path and filename for some (security) reasons. You can use either a h:commandLink or a h:commandButton for this:

<h:form>
    <h:commandLink value="Download PDF" action="#{myBean.downloadPDF}" target="_blank" />
</h:form>
<h:form target="_blank">
    <h:commandButton value="Download PDF" action="#{myBean.downloadPDF}" />
</h:form>

Note: when using an ajax-capable command button/link from a library such as PrimeFaces, then don't forget to turn off the ajax capability by e.g. adding ajax="false" in case of PrimeFaces command components. It's namely not possible to download files using ajax, for the simple reason that JavaScript is due to security restrictions not capable of forcing a Save As dialogue from the client side on.

The downloadPDF() method of the backing bean MyBean.java sends the PDF to the HttpServletResponse as follows:

package mypackage;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.Closeable;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletResponse;

public class MyBean {

    // Constants ----------------------------------------------------------------------------------

    private static final int DEFAULT_BUFFER_SIZE = 10240; // 10KB.

    // Actions ------------------------------------------------------------------------------------

    public void downloadPDF() throws IOException {

        // Prepare.
        FacesContext facesContext = FacesContext.getCurrentInstance();
        ExternalContext externalContext = facesContext.getExternalContext();
        HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();

        File file = new File(getFilePath(), getFileName());
        BufferedInputStream input = null;
        BufferedOutputStream output = null;

        try {
            // Open file.
            input = new BufferedInputStream(new FileInputStream(file), DEFAULT_BUFFER_SIZE);

            // Init servlet response.
            response.reset();
            response.setHeader("Content-Type", "application/pdf");
            response.setHeader("Content-Length", String.valueOf(file.length()));
            response.setHeader("Content-Disposition", "inline; filename=\"" + getFileName() + "\"");
            output = new BufferedOutputStream(response.getOutputStream(), DEFAULT_BUFFER_SIZE);

            // Write file contents to response.
            byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
            int length;
            while ((length = input.read(buffer)) > 0) {
                output.write(buffer, 0, length);
            }

            // Finalize task.
            output.flush();
        } finally {
            // Gently close streams.
            close(output);
            close(input);
        }

        // Inform JSF that it doesn't need to handle response.
        // This is very important, otherwise you will get the following exception in the logs:
        // java.lang.IllegalStateException: Cannot forward after response has been committed.
        facesContext.responseComplete();
    }

    // Helpers (can be refactored to public utility class) ----------------------------------------

    private static void close(Closeable resource) {
        if (resource != null) {
            try {
                resource.close();
            } catch (IOException e) {
                // Do your thing with the exception. Print it, log it or mail it. It may be useful to 
                // know that this will generally only be thrown when the client aborted the download.
                e.printStackTrace();
            }
        }
    }

}

The names of the getFilePath() and getFileName() are self-explaining, so there is no need to describe those methods.

If you don't care about showing request parameters or filenames in the URL, then you can also consider to use a FileServlet.

Hi Balu,

Thanks a lot for all your JSF articles. They have all been very useful.

I tried the sample for "PDF handling" and it worked fine by opening the pdf file on the same window as the commandLink.

I tried to implement the jsp file option - where the pdf opens in a new window other than the commandLink window. As soon as I click on the commandLink, it opens a new window and displays the "java null pointer exception" error. I believe I am doing exactly the same code as you given in your sample. Can you please let me know why I am receiving the error?

Thanks
Aish

BalusC said...

Some object in your code is null while it is been accessed. This would throw a NPE.

Read the stacktrace in the application server logs, find the root cause and fix it accordingly.

Sekar said...

Hi Baluc,

Just wanted to check with you if you had a chance to see my earlier response. If you get a moment, can you please take a look at the log and let me know why I am getting a JPE?

Thanks a lot

Hi Balusc,
I have two blob objects that hold the different pdf files.i want to show these two pdf files as one file using a servlet response.Could you please let meknow how could i do that?
I can show one file from the servlet response.if i try to combine them uisng the inputstream and display ,iam not able to .

BalusC said...

Use the iText API to merge PDF files in Java.

Kiran0927 said...

THanks for the previous response.

is there any way i could combine the blobs that contain the pdfs without using the iText API to display them using the servlet response.

Kiran0927 said...

Hi balusc,
As you suggested iam planning to use Itext api for combining the pdfs.

i am reading two blobs from data base as streams into a List Inputstream and returing that list using the stateless EJB to a servlet .My idea is getting that list in the servlet and concatenate them using the itext API to display as one pdf.
But iam getting an exception to read it from the bean.

exception is something like as below..

java.rmi.UnmarshalException: cannot unmarshaling return; nested exception is:

Let meknow if you got any idea about this error...Eventually iwant to use the way it was done in the below url..
http://java-x.blogspot.com/2006/11/merge-pdf-files-with-itext.html

Kiran0927 said...

hi Balusc,
Do you have any code to combine the pdfs that are in the BLOBS and display .
Could you pleas epost it if you have any code..

thanks

BalusC said...

Just get the byte array (inputstream) from the BLOB and handle accordingly.

Kiran0927 said...

Hi BAlusc,
I am getting the byte array (input stream) and was able to dispaly it when there is one pdf document.When i have more than one document,iam keeping all those byte arrays in a different list objects .allthose byte arrays iam writing them to an output stram to dispaly as one servlet response.At this point aim seeing an error in dispalying the pdf and could able to see a part of the first document alone.
let me know if you gto any code snippet to combine the byte array strams to dispaly in single servlet response.

thanks

BalusC said...

As said, you can use iText to merge PDF files. Just glueing the unchanged byte arrays together is NOT going to work. If you don't want to use 3rd party API's but rather write your own, then learn how PDF files are structured at binary level and write code accordingly.

Kiran0927 said...

Iam okay to user the Itext API .I am just wondering how to concatenate the pdfs using the API when i have the byte array in a list which i got from the blob.All i ahve in my servlet is List cotain different lists and each list contain the pdf files byte arrays.

Do you got any code for this type of list to read from itext apit to combine.

let meknow.
Many thanks for your valuable suggestions

Kiran0927 said...

Balusc,
LEt meknow if you have any idea as iam having issues when i try to use the iText APi .The exception when iam rreading the byte array using iText PdfReader is as below..


java.io.IOException: Unknown encryption type (4)
at com.lowagie.text.pdf.PdfReader.readDecryptedDocObj(Unknown Source)
at com.lowagie.text.pdf.PdfReader.readDocObj(Unknown Source)
at com.lowagie.text.pdf.PdfReader.readPdf(Unknown Source)

BalusC said...

Try posting this issue at the iText mailinglist.

Kiran0927 said...

Hi Balusc,
I am bale to concatinate the pdf with the help of iText API.The problem with was due to the standard security handler.iText api giving us the error as the pdf was the secutiry enabled with the password setup .
Anyway,Many thanks for everthing and i am very much happy to found your BLOG to discuss these king of issues with you.

Thanks you so much

Hi, I made a button for generating a pdf. When I run it localy its ok, but when I put the application on Tomcat I get the error: java.lang.NoSuchMethodError: org.apache.fop.fonts.FontInfo.fontLookup([Ljava/lang/String;Ljava/lang/String;I)Lorg/apache/fop/fonts/FontTriplet; org.apache.fop.fo.properties.CommonFont.getFontState(CommonFont.java:157)
although I have the library for FOP and the class FontInfo it's there..any ideas?

Thanks in advance

Daniel said...

Hi, first of all tanks for the great post,
My question is might be off the topic, but, I handled the pdf in the same way, and i also used the target="_blank" , but every time i open a pdf a get the new empty window being opened, i tried to close it from the servlet in couple ways, but without any luck, is there any recommended way to close the new window?
from servlet or using js sowmhow?

sri said...

Hi balusC,

I really appreciate your posts on JSF.

I am trying to open a PDF file on clicking a link from my portlet which is on JSF.

But my PDF files are stored on another machine.

I am using the physical path to my file to pen using h:requestLink

But the browser always looks in my local machines path to get the file and hence says file not found.

Can you direct me in the right way in making this work.

Thank you
Sri.

BalusC said...

Check the FileServlet link which I posted at the bottom of the article.

Daniel said...

Hi again... couple of weeks ago i posted a question in this thread...
Any cahnce to get a respond?

Thanks ahead...

A said...

Hi, BalusC,
Thank you for your post. But I tried you code solution for opening xml file and it gets opened in a new tab, not in a new window. Do you know any solutions to this issue?

BalusC said...

This is a browser configuration. Nothing to do against.

If you actually wanted a popup, use Javascript's window.open() with an URL pointing to some servlet like the FileServlet example.

success_21 said...

Hi Balu,

I tried your code and in the following way.

1. I added a h:commandLink in my page.
2. if i click the commandlink it will generate a PDF report and display the prompt to open or save. i am also able to open or save the PDF. Everything is fine till this point.
3. Now if I go to my JSF page and try to do any other actions (other than PDF commandLink), the corresponding action is called, and immediately after that action was called,it again shows up the save/open prompt again. I could not understand what the problem was. could you please help me to find out the issue?

jpedro said...

I've tried your tutorial with ICEfaces and this does not working.

What can i do?

thanks in advance!!

Elaborating the "not working" part in more detail.

BalusC said...

Sounds like some bug in IceFaces. Have you addressed this behaviour at their forum/mailinglist/issuetracker?

Helge said...

Hi,

I've tried your solution, but I tried adding the h:commandLink into a h:datatable. This didn't work very well, when clicking the link it didn't even invoke the downloadPDF-method, just loaded the same page in a new window. Then I tried putting the h:commandLink outside the datatable, and it invoked downloadPDF().

I'm trying to present a list over pdf-documents, and give a link to each of them, so I'd really like to access them from from the datatable...

Could you point me in the right direction?

Thanks,
Helge

BalusC said...

The data loading logic is apparetly wrong. The datatable value has to be same during the form submit as it was during the initial display (yes, that are 2 requests). Check the 'Using datatables' article.

Helge said...

Thanks, I was building the list in the backing bean, which obviously is no good idea if using a commandLink/commandButton. Instead I build the list in the BO.

The 'Using datatables' article was very useful.

Tarun Walia said...

Hi Balu,

Thanks a lot for all your JSF articles. They have all been very useful.
I am developing a application that shows file structure on the page using rich tree.
to download the file I have a context menu ,on clicking it call the action method same as yours.
its working well but when again I click on tree it shows the content of file on the page.how I can stop this.Should I Open a new window to download the file.
pls help me out.

BalusC,
I'm generating a pdf using code similar to you posting. I'm trying to open the pdf in a popup using:

h:commandLink action="#{MyBean.generatePdf}" target="#{MyBean.generate}"" title="Pdf" value="Pdf File" styleClass="shortcut_pdf" onclick="popWindow('', 'Generate','350','250','yes');cancelPropagation(event);">



The first time I click on the commandLink the browser creates the popup, goes out to the server to my MyBean.generatePdf method and creates the pdf in the popup. If I don't manually close the popup and click on the link again the main browser gets replicated in the popup.

I followed it in debugger on server and I see the first time it directly goes into my MyBean.generatePdf method but the second click only takes me into the getter for MyBean.generate and just returns the String "Generate".

Another thing I found is that if I try a third click it works correctly as it did the first time. Why wouldn't it see the action correctly the second time in?

ANy help is greatly appreciated.

Thanks,

Richard

Hello BalusC,
I am using your code for downloading an excel file. The content-Type I have given is "application/vnd.ms-excel". The code is same as yours.
But it on clicking the link the files is loaded in browser itself as text file.
I have also tried for pdf, and the result is same. the browser is firefox. And in IE-7 even the text is also not shown. I am using myfaces 1.2 implementation for jsf.

Hi BalusC,
Thank you for you post.
I've tried to do this in my JSF application. The browser(IE6) is always displaying the content of the pdf file in text format in the browser instead of opening the file with a pdf plugin.

I'm using your code with almost no changes.

Any ideas ??

Thanks in advance.

Hi BalusC,
You code is working when I had it in a simple servlet.

BTW I've forgot to mention I'm using Richfaces 3.3.2.

I think it has to do with a4j:commandButton. I replaced this with h:commnadButton. Now the pdf is displayed in the browser.

Hi..I used the code to open an excel sheet from jsf application and it worked fine. However I have another button the page that is used to do something else. When i view the excel file on this page and click on the hoer button the page doesn't get submitted for the first time. It gets submitted when i Click it again.

If I remove the part of code for opening the excel sheet from the action method of the first button everything works fine. Can you please explain why opening an excel sheet breaks the second button for the first time.

Bauke Scholtz said...

Make sure that you're not invoking the action method by ajax. It's not possible to download files by ajax.

am i using an iframe not a command button since i want to display the pdf in an iframe so i dont have a component which has ajax my code is calling downloadPdf in a PostConstruct method and the iframe is taking the file name as src

I keep stumbling upon your blogs for a while now, always clear and well explained info which helps me lot in dev life! A big thumbs up there! However this one didn't do it for me =( Don't know why, there is just nothing happening, no useful log entries, nada.
I managed to fix it though by combining your fileservlet blog with a simple prettyfaces mapping. Overkill? Probably. Maybe I blog about it one day myself =)
Cheers from the Netherlands!

Hi Balu.
Thanks for the article. It worked well for me in IE, Chrome n firefox.
Is there a way where i can do the same for ipad, tables and smart phone. I failed using the same method for samsung tablets

Hey Bauke Your tutorials are really of great help. I need help in converting xhtml page to pdf. Can you guide on those lines with some reference.
