Java creating PDF file

I am currently working at a project which generates contracts. The idea is that I put the data in a form and save it in a simple database.
So long, this was my favorite place to search for good ideas and simple solutions.
Now I am facing another problem and I don't know how I can solve that. I want to create a PDF and replace some placeholders with some data from my form.
One idea was, that I use an existing Word template with some bookmarks and replace them with the data from my form. Maybe there is a way to do that, and I am just too stupid to find it.
Another idea was, that I am using XML. Therefore, I thought I was clever and just converted the Word template to an PDF, so I am able to convert that PDF to an XML. Attached, you find the XML file. But now I need the XSL file - is there an easy way to create the XSL file?
Or maybe there is another simple solution to solve my problem.
In these attachments you find the PDF file, the Word template and the XML:
Thank you a lot :)

Using a template is a good idea - it makes some changes much quicker to make and then deploy. The comments above are focused on conversion, but don't forget you need to merge your data in (population) first.
If you can use Adobe tools, you can have a PDF template and use the Adobe tools to populate. This saves a "conversion" stage.
You mentioned using Word for templates. This means you to run through two stages of processing:
population - docx is a zipped set of XML files - so you can process them with your own code or using a library.
conversion - you need pdf, so you have to convert the docx to pdf. You also have to watch out for fonts at this stage (ie make sure they are available on your host).
The population stage you could do yourself since you are familiar with XML. But it is definitely complicated. The conversion needs to use a tool that is ideal for it. There are a few mentioned in the comments already.
There are some free/os and commercial tools that can do both parts:
docx4j
JOD Reports
Libre Office (using the Java Uno API) (I blogged this once - Java Convert Word to PDF with UNO)
Docmosis (please note I work for Docmosis)
I suggest starting with the simple example you have attached and prove you can both populate and convert that. Then switch to a more complicated example to see if you can do the other things that might be required (eg repeating or conditions or other logic) during the population stage.

Creating Docx, PDF, XSL-FO

[Background Info]
We had a solution in place to use Word automation serverside to convert HTM documents into Docx, PDF or Print documents. This solution broke in the latest version of Windows Server 2012. We learned that MS does not intend on Word working in this manner and after trouble shooting with MS support Engineers we have come to the conclusion that it will never work.
[Currently]
I am currently researching potential technologies and tools that my company can use to regain this functionality. We need to be able to create Docx, PDF and print files to a local printer.
I have looked into a number of tool already and I am currently leaning towards Apache FOP this seems to handle PDF and Printing for us.
However, I'm looking for some advice and suggested tools that we could use to implement a pure Java approach. Currently our application creates HTM files with all the required information. So ideally we would like to take these HTM files and "Convert" them into Docx/XLS-FO format.
[Question]
So my question that I'm hoping you will be able to help me with.
What is the best tools that I can use to get from
HTM to Docx
HTM to PDF
Or what would be the best process for achieving this? has anyone had success finding a solution for this in the past?
Thank You

It depends on the level of control and the complexity of the source HTML. There are HTML to FO stylesheets but you might find them wanting for your specific need.
So you could use the Jericho parser to read the HTML and generate FO. Or you generate the target format directly using Apache PDFBox and Apache POI
It all boils down to the level of control you want/need

docx4j-ImportXHTML will get you from XHTML to docx. From there, you can use docx4j (or some other solution eg LibreOffice/OpenOffice) to do docx to PDF.
docx4j supports docx to XSL FO, and by default uses FOP.

extracting text AND Images from PDF file

I have been bumping my head against the wall with this one, have researched and pretty much tried every library suggested to me. I am currently trying to write a program in java that will extract text AND images from a pdf file and allow me to write the extracted content to a word file. I have managed to extract the content using the ICEpdf library, however the problem is that I need to be able to write the content in the exact same order as it was read. So, to clarify, I need a library that will help me keep track of where exactly in the page the text and images are situated so I can put them in the same place in my word file.

A PDF to Word converter is a horribly complex proposition.
Your best bet will probably to use Open Office to do it for you and not even try to handle the intermediate steps.

Look at this: Advanced PDF parser for Java
OFF:
-Also to my knowledge there is a python parser that sorta converts the pdf to html (that way you can keep track of the ordering of the objects within the pdf). I know its not java, but you might be able to use the output.

Convert html+css+js to PDF

I want to create something like this (code is here):
in pdf format. I'm using google charts and regarding to this forum converting chart to pdf is impossible. I've already tryied iText+XMLWorker, but there is some problem with css and any js supporting at all, I think.
So, the questions are: How can I convert html+css+js to .pdf file? Or, may be, the issue have other variants?

As promised in the comment, I've asked Raf. This was his answer:
One way to use XML Worker for HTML+CSS+JS is to use a browser engine to preprocess the HTML. Examples of such a browser engine are WebKit (Chrome, Safari) and Gecko (Firefox). These can interpret the CSS and JS and give you HTML that is ready to be parsed by XML Worker.
Examples of competing products are:
wkhtmltopdf, a command line tool that uses WebKit as its rendering engine.
Prince XML supports HTML+CSS+JS to PDF using their own engine.
Maybe there are others, but this is what Raf told me. I hope this helps.

How can I use Java to take a "screenshot" of displayed HTML?

Do you know how to convert (save) HTML to an image? Any format is acceptable: jpg, png, ... I tried this code but it does not correctly convert images from HTML (<img> tag).
A solution in Java would be preferred; however, I would appreciation any approach.

Well, here is the outline of a solution, at least:
You need a HTML renderer (Gecko, Webkit et al). Then you need to capture it's "output".
The first approaches that spring to mind are
Create a batch tool yourself, using an open source rendering engine - then render this to an image. This could be done with Qt and QWebKit, maybe even with Qt Jambi (for java). There is an example for c++ here, in the Qt developer blog.
Automating an X11 browser and using capture to capture the contents of the window. Could be a problem with scrolling, IDK.

One solution would be to use WebDriver
Another solution could be provided by this article : Capture screenshots with Selenium
They are both Java solutions.

Your description is a little shy on what your trying to do. Could you please give more details?
If you are just trying to take the html and make an image of it what you might want to try is to create a new image and insert the html as text into the image. Once that is done, you can save the image to the type of your choice. I don't know if this is what you are looking for though.
