The iText library contains classes to generate PDF text in various fonts, generate tables in PDF document, add watermarks to pages, and so on. There are many more features available with iText. It is not possible to demonstrate all of them in a single article.
We will cover the basics required for PDF generation. For more detailed information, refer to the documentation from the vendor.
We will use Eclipse for the development of our sample application. Being an open source IDE, Eclipse is freely available and quite powerful. You can download Eclipse now. The com. Document is the main class for PDF document generation.
This is the first class to be instantiated. Once the document is created, you require a writer to write into it. PdfWriter is a PDF writer. Some of the other commonly used classes are given below:. What can demonstrate any technology better than a working sample, created by your own hands? Now that you have the requisite tools Eclipse IDE and libraries iText librarywe are all set to design and develop a sample running program.

December 20, at AM.In this tutorial, we will discuss how to extract a database table data specifically Oracle to a PDF report in table format, using Java programming language. These details will be used by the program to connect to the instance. We also attach the column data to the table in this step.
This writes the report to the PDF and we close the document following this action. The report is ready! FileOutputStream; import java. If you have a question, you can post it in the comments section. Thank you. Its working good.

The code fragment that does this is given below:. In this step, we add the logical report table created out of the earlier step, to the PDF document. As good programmers do, we close all connection objects Query, Statement and DB objects at this step.

Spring MVC - Generate PDF Example
Radioset Radioset to Filter a List. To generate the PDF as shown in the above example, the following jrxml template was used. HttpServletRequest; import org. Logger; import org. LoggerFactory; import org. Autowired; import com. SecurityService; import com. ExposeToClient; import com.
HideFromClient; import org. HttpClient; import org. HttpMethod; import org. GetMethod; import java. HashMap; import javax. HttpServletResponse; import net. JasperReport; import net. JasperDesign; import net. HtmlExporter; import net.
JRPdfExporter; import net. JRXmlLoader; import net. SimpleExporterInput; import net. SimpleHtmlExporterOutput; import net. SimpleOutputStreamExporterOutput; import net. Set the Source Property from the properties panel for Iframe.
You can download the PDF file. The complete output is as follows:.Basically I want to connect a form to a database and have the user to select on enter information to a field. Then have it to queier the database and fill in the form with the information in the database.
Is this possible to do? If it is how? Wow, you have got a few bumps to get over before you will be able implement anything close to what you are talking about doing.
So the user's only needs Acrobat or Reader, they do not need LiveCycle to use these forms. LiveCycle is only a design tool for creating the form. XFA forms are a relatively new technology. There is also a traditional AcroForm model. But both form types are displayed and used in Acrobat and Reader.
By local, I mean a DB on the user's file system. Possible a shared drive. It is possible to connect the form to a remote DB, but the user will need to have the correct DB drivers installed on thier own system. This DB connection will not work or work reliably for random users on the internet. Also, it only works for users on Windows. A Mac user will not be able to use a DB connected form. The only way to reliably connect the form to a remote DB, for any user, on Windows or Mac, and from Reader or Acrobat, is through a server script that handles the data transactions.
Your project is not impossible, it's just a steep uphill climb. Too much for one post. Have you looked at the Learning Center on this site? It only works reliably or at all for a local database. It does not work for distributed forms, and there are big issues for Win 7 and 64 bit because the necessary drivers aren't there.
How to create and export PDF files in Java
And it only works on Windows. There is no equivelent for Mac. Another option is to connect the form to a server DB throught the form submit functinality. To do this you need to write a server script to handle the actual transactions with the DB.
If you're using a version of Acrobat prior to X, then you can do it with a form created in Acrobat you don't have to use LiveCyclebut it is quite tricky and requires a lot of scripting knowledge. It only needs to pull the records that is associate with that one partical person. It is basically like doing a Mail Merge in Microsoft Word. The file would have to be posted to the intranet site where the extended right would have to be applied so the end user would be able to use it.
I would have the IT guy at the site to setup the local databases for the users. It seems like this project is going to be impossible to do because the end user is not going to have livecycle just adobe reader.
Plus if it is anything more than them entering in a name or pressing a button it might be a little too much. We just got Microsoft Office here a year ago. Plus they have most of the sites blocked and disabled the capability to watch videos on the internet to learn how to do the things that they need me to do and I don't even have full access to everything on my computer.

I am using Spring MVC. I have to write a service that would take input from the request body, add the data to the pdf and returns the pdf file to the browser.
The pdf document is generated using itextpdf. I have tried using this. I am just putting some random data in the pdf for time being. I am sure this is wrong. Please help me out. You were on the right track with response.
Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:. Learn more. Asked 6 years, 11 months ago.

Not necessarily; however, since the beauty of a PDF created from your Oracle database is having non-editable point-in-time documentation of the data of interest, the work necessary to create and store the PDF could be well worth the investment.
Many Oracle applications' reports are already being converted to an XML friendly format.
