I've made a form in the PDF document and all works well. However, when the content of the document extends over to the second page, the form fields are applied to the second page instead of the first page where the table is.
If I switch the statement writer.addAnnotation(form) to a line before the content that causes the creation of the second page, then all's fine. However, if I add it to the end of the document, this form is applied on the second page.
Is there any way to overcome this? Is there a method I'm missing that allows me to set the page to which the form is applied?
Additionally, I wish to keep one single form that spans across multiple pages with paragraphs between the fields.
Another method of overcoming this is by adding each field to the document as and when they're created instead of adding the entire form at the end of the document as shown in the examples.

My document has Title page (First page) and a Table of Contents (Second page). The requirement is to not have a footer on those two pages only, and the rest will get a footer.
As per XWPFHeaderFooterPolicy, I can only find the following:
static org.openxmlformats.schemas.wordprocessingml.x2006.main.STHdrFtr.Enum DEFAULT
static org.openxmlformats.schemas.wordprocessingml.x2006.main.STHdrFtr.Enum EVEN
static org.openxmlformats.schemas.wordprocessingml.x2006.main.STHdrFtr.Enum FIRST
I know I can add a blank footer on the first page using XWPFHeaderFooterPolicy.FIRST, but I do not know how to do it on the second page.
Is there a way to accomplish it? or perhaps can we delete a footer on a specific page?
I got stuck with PDFBox, trying to integrate a table/list in my acroform.
What I have:
I have a PDF-Template with form fields, which I fill with PDFBox in a JSF application. I must have these templates, because users can upload custom templates (they only have to insert form fields with defined names, that the application will fill).
Now I have the problem, that I want to be able to print a list on a defined form field. This template starts e.g. with a header with logo etc. Then in the middle it has a kind of placeholder where the list/table will be printed. After this a kind of footer (e.g. with signature, ...) will be included. All the content after the list/table must move downwoards, to avoid the table be written over the footer content.
My Questions:
(How) Can this be done with PDFBox?
Can the content under the list be moved downwoards, when the table becomes longer?
I have to create a pdf using itext which will contain a button, when clicked should add a row in an existing PdfPTable. I wrote some code to create a PushbuttonField. While trying to set action I can only find PdfAction.javaScript. I am not able to figure out how to add a row in a table. I tried searching online but all I could find is PdfAction.javaScript
Any help would be greatly appreciated. Thank you.
When you create a PDF file, you draw text, lines and shapes to a canvas. That is also what happens when you add a PdfPTable to a Document. If you look at the syntax of the PDF page, you won't recognize a table. You'll find text (the content of the cells), lines (the borders), and shapes (the backgrounds), but you won't find a table. If the table is distributed over different pages, the "table" on one page won't know that it is related to the "table" on the other page.
Sure, you can add semantic structure to the document by introducing marked content, and by creating a structure tree, but that mechanism which we call Tagged PDF can't be used to make the PDF "editable" the same way a Word document is editable. Tagged PDF is (among others) used to allow assistive technology to present the content to the visually impaired (e.g. in the context of PDF/UA). The presence of structure doesn't change the fact that all text, all lines, and all shapes are added at absolute positions.
This is very different from HTML where the position on a page of a <table>, <tr>, <th>, or <td> is calculated at the moment the page is rendered. In HTML this position can even change when you resize the browser window.
There is no such thing in PDF (except if you use XFA (*), a technology that is deprecated since ISO 32000-2). All content on a page has a fixed position, hardcoded into the page's content stream. Changing the size of the PDF viewer window won't change anything to the position of the page content.
Because of all of this, your question is invalid. It is impossible to create a button in PDF that adds a row to a table, because:
In many cases there is no table: there is just a bunch of text, lines, and shapes at absolute positions,
Even if there is the notion of a table (using Tagged PDF): the visual represenation of that table is fixed at creation time, it can't be changed at consumption time.
You want to use an ordinary PDF viewer as if it were a PDF editor. That is impossible for all the reasons listed above.
(*) XFA was deprecated for different reasons. One of the most important reasons it is the lack of support for XFA. There aren't many viewers that support XFA. If you would post a follow-up question asking *"How can I create an XFA document?", the answer would be: "Don't do this!" Creating XFA is extremely complex, and once you've succeeded in creating an XFA form, you'll discover that many of your customers won't be able to consume the file because their viewer doesn't support the format.
I am trying to combine two or more pdf documents so that the pieces on each document appear on one page in a new pdf.
The pieces on each document contain a form with multiple fields, but the forms only take up a fraction of a page. I know the typical way to merge documents in iText is PdfCopy.addDocument(reader), but I don't want each doucment on it's own page.
Is there a way to copy the fields and/or acroform of each document and put it into a new document where the snippets flow one right after another?
One way I have been thinking about doing this is creating a table with one column in a new document and adding each snippet into a cell, but I haven't been able to get it yet and I don't know if that is even possible.
Or is there a way to make the form a template and copy the template and put it into a cell in a table or on a new document? I don't want the template for the entire page, just the form with the fields.
I also realize that PDF is page-based, but I was hoping there would be a way to combine two pdf pages with form fields onto one page. Also, my fields do not need to be interactive. The forms are already filled out and can be flattened if they need to be.
I have a requirement to convert a PDF from HTML using itext lib in java.
My input HTML page has a tabular structure and it has separate header and footer. I've converted this page to PDF , however as my HTML page has a footer associated with it, I'm trying to relocate footer of my generated PDF to location where actual data of a particular page ends(i.e if a page contains only 10 lines of data from header then I'm trying to add footer after 10th line). PDFEventHelper class helped me to add header and footer,but I'm getting struck with this relocation requirement.
Can anybody tell me how to deal with such scenarios??
does anyone knows how to read blank(unwritten) sectors on PDF page ??
Thanks in advance.
The Document passed into your onEndPage override is actually a PdfDocument.
Once you've cast the parameter to a PdfDocument, you can call PdfDocument.getVerticalPosition(true) to determine where the last Element was laid out and draw your footer accordingly. Note that this only gives the Y position, but that's all you really need for a footer.
The parameter passed to getVerticalPosition is called "ensureNewLine". I strongly suspect what you pass won't matter because this is the End Page Event, and any trailing lines will have already been written/finished/closed/whatever-its-called.
