Iii JavaServer Faces Specification. March 2017 1.2.3 Application Developers 1–13 1.2.4 Tool Providers 1–13 1.2.5 JSF Implementors 1–14 1.3 Introduction to JSF APIs 1–14 1.3.1 package javax.faces 1–14. Files of the type JSP or files with the file extension.jsp can be easily converted to PDF with the help of a PDF printer. A PDF printer is a virtual printer which you can use like any other printer. The difference to a normal printer is that a PDF printer creates PDF files. You do not print on physical paper. JavaServer™ Faces (JSF) is the standard component-oriented user interface (UI) framework for the Java EE platform. In terms which may sound more familiar, it's a Java-based web framework. JSF is included in the Java EE platform, so you can create applications that use JSF without adding any extra libraries in your project.
posted 15 years ago- JavaServer Faces This IBM® Redpaper™ publication introduces the features, benefits, and architecture of JavaServer Faces (JSF), a framework that simplifies building user interfaces for web applications. This paper is intended for web developers interested in JSF. The paper includes.
- Java Server Faces (JSF) technology is a front end framework which makes the creation of user interface components easier by reusing the UI components. JSF is designed based on the Model View Controller pattern (MVC) which segregates the presentation, controller and the business logic.
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?

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.

sorry, this is my first time generating pdf so i'm not really sure what do i need and how do i do that.

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..

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?
Checkout my snippet of code.

Eve eft for mac. 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 youThats 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.
