I am using a Spring Boot application and I need to dynamically populate the blanks in an existing PDF using the values from the database. I have attached the image of the PDF for your reference.
I want to know the best practice to do so. Please guide me.
Image of the PDF which I want to dynamically populate
I have used now Itext version 7. Where i have created the exact replica of the existing PDF using Itext table cells.
When you are writing the generation code itself in JAVA then there is no problem in mapping the data into the same.

In my current java/springboot project, I need to create a PDF dynamicaly containing paragraphs, images and tables.
And I also need to add the table of content of this document.
I'm wondering if there is a way to automatically generate this table of contents using either openPdf or pdfBox.
I noticed that it is possible to do so using IText, but it is not free...
Thanks in advance for your help.
You can use OpenPDF for this: https://github.com/LibrePDF/OpenPDF
Also see Flying Saucer: https://github.com/flyingsaucerproject/flyingsaucer
Actually neither openPdf nor pdfBox provide a way to automatically generate table of contents :-(
iText provide us with such functionality, but it is under AGPL licence so cannot be used in my case...
For the time being, I will try acheive my needs using apache POI then convert the generated docx to pdf using opensagres/xdocreport (see: Trying to make simple PDF document with Apache poi)
I am working on an application that generates a xdoc output with a series of charts and tables, whose data comes from a given excel file. Currently I have been able to generate the necessary charts and tables managing the data with Apache Poi and generating the actual charts in a separate excel file using GCExcel, nevertheless, Apache does not include support to turn XSSFChart objecs into images in order to insert them into the document, and GCexcel's unlicensed version doesn't allow me to exoprt charts to images either. Anybody knows a way in which I can work around this issue?
Check out Spire.XLS library.

I am not sure if this will actually work because I did not implement something like this before.
I'm creating an Java application for self-employed workers. In this application, the self-employed workers can keep track of hours worked on different projects. Storing hours worked on different projects is now working. I store it in a MySQL database. Next step is to use this data and create invoices. The first option I want to work on is creating an invoice in PDF format. Could you suggest an approach?
One approach is generate an XML document and use that to generate the PDF document. Possible with a template containing a pre-formatted invoice. But how?
Another approach may be to generate a PDF using pure PDFBox. You can use a background image as a template and then overlay it with details that you retrieve from your DB.
You can use Apache FOP to generate a pdf from a xml using xsl transformations
You can use iText library for creating pdf. Its open source and easy to use with Java. Also the documentation provided by iText team is very good for starting any PDF generation project.
I have the need to create some pdf through java code, pdf templates are fixed and are very complex too. Each pdf represents a module and I have to fill it with informations I get from other sources in my application and finally create the complete pdf.
So, is there a library which, given a pdf, scans it and creats some java code which will eventually create it back? This way once I get the pdf template in java code I just have to edit it adding my informations and create it back.
You can check these 2 link it's have all information regarding PDF CRUD operation.

I have used with success iText http://itextpdf.com/ for various tasks involving creating, parsing and modifying pdf files. Please not that this one is not free for commercial use and the pricing isn't cheap either.

itext API'S
I am currently looking for a solution to populate a PDF file from the java code, Is there any APi for that, I googled it and found JustformsPDF does the trick, but it works only for some pdf and not all + its a old API without recent developments/support.
Basically I have an existing PDF (and do not want to build it) I just need to populate my java data inside that pdf.
any suggestions ?
These two should be able to do the job (these are the ones I know, there may be more):
Apache PDFBox
iText
You can use our product PDFOne (for Java). It has a document component that can also fill form fields in existing PDF documents. Viewer and printer components are also available.
