The PDF online converter can convert from Microsoft Word to PDF as well as a lot of other formats. If the PDF contains only scans from text pages, you can convert it to a searchable PDF file using the OCR functionality. If you want more advanced features like rotate, merge or sort PDF pages, you can use this free PDF editor. How to Convert HTML files. Click inside the file drop area to upload an HTML file or drag & drop an HTML file. Note: You can upload ZIP archives that contain an HTML page along with resources.
I need your help and guidance on how to export a full jsf page to PDF. In my jsf page, I have a button to export to PDF and some fields where I am retrieving the values from a database. The form is ready but I don't know how to program code or program a button to export the page to PDF. I tried to search for an easy and a standard way but unfortunately I didn't find any useful example or code. Could you please instruct and to guide me on how to this.
Thanks

However, it's more likely that like most people you don't really want to 'export the JSF page to PDF', you want to generate a downloadable document in PDF form for viewing, printing and/or saving on the client's machine. Which is entirely different.
And you probably don't want the PDF to literally resemble the screen display, you probably want to construct the PDF to look better as a printed document.
If you literally wanted the screen display in PDF form, Linux (and probably Mac) users can simply use their browser's 'Print as PDF' printer option. I think that this MIGHT be available in newer versions of Windows, as well, but if not, there are 3d-party printer drivers that can do the job.
However, if you want to generate a printer-friendly PDF document, don't do it in JSF. Write a standard (non-JSF) servlet and use one of the available PDF rendering libraries to render the servlet output stream as a PDF. Pass any data you need to exchange between JSF and the servlet in session- or application-scope objects.
JSF wasn't intended to be a do-everything framework, and PDF's are one of the things that it wasn't intended to do.

Some people, when well-known sources tell them that fire will burn them, don't put their hands in the fire.
Some people, being skeptical, will put their hands in the fire, get burned, and learn not to put their hands in the fire.
And some people, believing that they know better than well-known sources, will claim it's a lie, put their hands in the fire, and continue to scream it's a lie even as their hands burn down to charred stumps.
What libraries do you recommend to read about? Are there any examples?
I often use Apache FOP, which allows me to use an XML template for the document instead of coding the document elements in logic.

What do you recommend for beginners? Is it Itext or Apache Fob?
The PDFs will contain only text, 2 tables and few fields to be retrieved from the database?

i'm planning to let user to print in pdf format when they click the 'print' button..
any suggestions on how to start with it?
Jys<br /><a href='http://jy-s.com' target='_blank'>
and this line.. response.getOutputStream().write(yourdata[]);
i will pass all the things i want to retrieve from database here? do u happened to have a complete example for me to refer?
thks in advance..
Jys<br /><a href='http://jy-s.com' target='_blank'>
sorry, this is my first time generating pdf so i'm not really sure what do i need and how do i do that.
Jys<br /><a href='http://jy-s.com' target='_blank'>
Jys<br /><a href='http://jy-s.com' target='_blank'>
hmm.. might used that, but still not sure how they do column and etc .. cos wat i can see is that they only using paragraph.. cos i'm generating reports, so they will be a lot of columns and tables involves...
in my jsp page, how can i called the backing bean? cos if i were to use jsp to generate pdf(s), i may need to refer to backing beans to do retrieval from the database.. and i think i won't have any jsf tags in that jsp page that generate pdf...
Jys<br /><a href='http://jy-s.com' target='_blank'>
Remember that method I showed you?
Ok, lets change that just a bit...
Now, supose you have a commandButton that calls a backing bean method called generatePDF(). Let's take a look at what that method might look like..
And that's it. It can all be done in the backing bean. That is what we have been trying to convey.
it will work
am doing this works great with itext.

Hello sridhar panini,
Please, can you give me the libraries used for this code? Thank you
I will suggest use Jasper reports, you will get the PDF within no time.
I have the made a sample long ago. If you want let me know.

I tried to use JasperReport 3.7.5 but I got some problemes. This my code with JasperReport
When I run this code, I get an empty pdf. Please can you help me to use Jasperreport to make my Reports.
Thank You
I didn't look at the code before. Try to pick .jasper directly from IReport and see.
It should work. From where you data is coming?

I can see that you are using the compiler inside the code. I wanted to know from where
your data is coming?

I wanted to know from where your data is coming?
With ireport, I defined a Database JBDC Connexion. And, in my jrxml file, I used a query whose the database connexion parameters are defined in the Database JBDC Connexion. I hope that I answered correctly to your question. English isn't my mother tongue, so excuse me for my bad english
Thank you

posted 9 years agoThats true. So basically is your query parameter based, like a criteria query. For example, find all all employees
whose salary is greater then your specified parameter. If you see that, you are passing a empty hashmap to your
jrxml. You are not passing any parameters. You need to put your parameters in the hashmap and send that hashmap.
Be sure that your your parameter in Hashmap is of the same name as in the JRXML.

Where are you calling the getConnection() method to get the connection. In your code, i don't see anywhere that you are calling
the getConnection method.
Put in your printPdf() method as
I feel your connection reference is not properly initialized.
Have you checked your SQL in a editor like SQL editor, is it returning any results? Additionally, try to use the .jasper file directly and comment
the JRXML compile. To me your JRXML looks okay. Additionally, check is is your connection object null means is it able to correct to database
properly?

Now the report is generated, but I can't open it because it is used by another process. After verification, this is the process 'java.exe' which use the genereted report.
I try to resolve it. Please, don't forget me If you have an idea to resolve the probleme.
I appreciate the attention you have given me
Can you tell me what exception you are getting exactly? Additionally i would like to know did you try to use
.jasper file directly rather then using the built in compile utility.
