Strictly speaking, one would render a JSF View as PDF using an alternative renderer instead of the default HTML renderer. 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.
posted 15 years agoi'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.

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.

Skype for business problem verifying certificate.
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.

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.
HTH,

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.

The Definitive Guide to JSF in Java EE 8 Book Description:
Learn and master the new features in the JSF 2.3 MVC web framework in this definitive guide written by two of the JavaServer Faces (JSF) specification leads. The authors take you through real-world examples that demonstrate how these new features are used with other APIs in Java EE 8. You’ll see the new and exciting ways JSF applications can use to communicate between a client and a server, such as using WebSockets, invoking bean methods directly from Ajax, executing client-side JavaScript when Ajax calls complete, and more.
Along the way you’ll broaden your knowledge of JSF components and web APIs best practices, and learn a great deal about the internals of JSF and the design decisions that have been made when building the JSF API. For example, you’ll see what artefacts are now CDI injectable, how CDI changed JSF internally, and what some of the caveats are when working with the CDI versions of a JSF artefact.

Furthermore, you’ll build an example application from scratch. After reading The Definitive Guide to JSF in Java EE 8, you’ll be ready to build your own efficient and secure web applications.
What You Will Learn
- Leverage the new features in JSF 2.3 in your existing applications
- Integrate JSF and CDI
- Use the brand new Component Search Expression framework, which enables you to more easily locate components from your template
- Extend the Component Search Expression framework with your own search operators
- Work with the different ways of mapping requests to JSF, make your application use extensionless URLs, and programmatically inspect which resources are present in your application
- Master the best practices for web application development and see which are obsolete
Who This Book Is For
Existing JSF or Java developers who need to create a web UI. No prior knowledge of JSF is required, but the book does skew towards the more experienced developer. Concepts such as dependency injection and MVC are assumed to be known, as is a general knowledge about HTML, HTTP and other web standards.
