I'm building an android app and I want to use iText for creating pdf file, but I can't use Document class. As I seen in tutorials, there should be import com.itextpdf.text.Document for using Document class. For this app, I'm using com.itextpdf:itext-pdfa:5.5.9 library. I want to create a simple pdf file with 2 paragraphs, something like this:
try{
File pdfFolder = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOCUMENTS), "pdfdemo");
if (!pdfFolder.exists()) {
pdfFolder.mkdir();
}
Date date = new Date() ;
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(date);
File myFile = new File(pdfFolder + timeStamp + ".pdf");
OutputStream output = new FileOutputStream(myFile);
Document document = new Document();
PdfAWriter.getInstance(document, output);
document.open();
document.add(new Paragraph(mSubjectEditText.getText().toString()));
document.add(new Paragraph(mBodyEditText.getText().toString()));
document.close();
}catch (Exception e) {}
'
Could anyone help me with this problem? What am I doing wrong?
You say:
I'm using com.itextpdf:itext-pdfa:5.5.9 library
That is wrong for two reasons:
itext-pdfa is an addon to iText that is meant for writing or manipulating PDF/A documents. It requires the core iText libary. Read about the different parts of iText on the official web site: https://developers.itextpdf.com/itext-java
You say you want to use iText on Android, but you are referring to iText for Java. iText for Java contains classes that are not allowed on Android (java.awt.*, javax.nio,...). You should use the Android port for iText, which is called iTextG: https://developers.itextpdf.com/itextg-android
It's as if you're using iText without having visited the official iText web site. How is that even possible?
Just open your app level gradle file and add following code into your dependencies
implementation 'com.itextpdf:itext-pdfa:5.5.9'
It works for me

I have dynamics docx with few tables and I'm trying to convert to a PDF. When I converted to PDF then it covers two pages. I use Apache POI XWPF converter in 2.0.2 version.
In docx file everything is okey but when I convert to PDF then tables are spited
Someone have any idea or better library to convert docx to pdf?
PdfOptions options = PdfOptions.getDefault();
options.fontProvider((familyName, encoding, size, style, color) -> {
try {
BaseFont baseFont = BaseFont.createFont("fonts/times.ttf", encoding, BaseFont.EMBEDDED);
return new Font(baseFont, size, style, color);
} catch (Exception e) {
throw new RuntimeException(e);
}
});
PdfConverter.getInstance().convert(document, out, options);
There is no library to convert a doc[x] file into a completely correctly formatted PDF. The only program that can do that is Word itself.
I have achieved this by using the Word API in a PowerShell script:
$document_path = $args[0]
$document_parent_folder = $args[1]
$file_name = $args[2]
$word_app = New-Object -ComObject Word.Application
$document = $word_app.Documents.Open($document_path)
$pdf_filename = "$($document_parent_folder)\$($file_name)"
$document.SaveAs([ref] $pdf_filename, [ref] 17)
$document.Close()
$word_app.Quit()
Yes it is not the best solution and it is heavily dependent on having Microsoft Office installed in the machine and a lot of other problems that accompany this solution... But it is the only solution that formatted my documents exactly how I wanted them.
The script takes three arguments
The path of the document that will be converted
The folder where it is located
The name of the pdf file
doc file in byte[] type.
Is it possible to convert it from byte[] into .docx file.
tried just change file extension programilly but it does not work.
any suggestions?
I generate report using BiRT eclipse
code of saving doc:
options = new RenderOptionBase();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
options.setOutputStream(bos);
options.setOutputFormat("doc");
if(parameters != null){
task.setParameterValues(parameters);
}
task.setRenderOption(options);
task.run();
return bos.toByteArray()
//IRunAndRenderTask task;
problem is that we use BIRT 3.7 which not support DocxRenderOption
Take a look at Aspose.Words for Java -- http://www.aspose.com/java/word-component.aspx
It has really good doc too -- http://www.aspose.com/docs/display/wordsjava/load+or+create+a+document
Code will be as simple as
// Open a document.
Document doc = new Document("input.doc");
// Save document.
doc.save("output.docx");
Step1: save the doc file
Step2: using this lib convert the file and save as docx file.
I've recently been working on an automated system to make and print out letters to post. The system works as follows:
I create a file, with all the information in it, and replace some things with %... placeholders. For example, %name, %date, etc.
When I run the application, I can select a name from the list, and it automatically loads the document, replaces all the placeholders with information supplied by a MySQL database, and prints out the document. For testing purposes, I'm just saving the document for now.
I've found some tutorials on the internet, and found a code that suited my needs. Unfortunately, this code only works for Word versions older than 2007 (.doc files). What would I change for 2007+ compatibility (.docx files)?
public static void main(String[] args){
try{
FileInputStream fis = new FileInputStream("/Users/Jasper/Desktop/document.doc");
POIFSFileSystem fs = new POIFSFileSystem(fis);
HWPFDocument doc = new HWPFDocument(fs);
Range range = doc.getRange();
range.replaceText("%name", "Jasper");
range.replaceText("%age", "17");
FileOutputStream fos = new FileOutputStream("/Users/Jasper/Desktop/document2.doc");
doc.write(fos);
fis.close();
fos.close();
}catch(Exception e){
e.printStackTrace();
}
}
Please see my answer here I used this solution to automate generation of documents and it has been used since more than 1 year on production.
I have a web application. I've generated MS Word document in xml format (Word 2003 XML Document) on server side. I need to show this document to a user on a client side using some kind of viewer. So, question is: what libraries I can use to solve this problem? I need an API to view word document on client side using java.
You cannot reliably display a Word document in a web page using Java (or any other simple technology for that matter). There are several commercial libraries out there to render Word, but you will not find these to be easy, cheap or reliable solutions.
What you should do is the following:
(1) Open the Word engine on the server using a .NET program
(2) Convert the document to Rich Text using the Word engine
(3) Display the rich text either using the RTF Swing widget, or convert to HTML:
String rtf = [your document rich text];
BufferedReader input = new BufferedReader(new StringReader(rtf));
RTFEditorKit rtfKit = new RTFEditorKit();
StyledDocument doc = (StyledDocument) rtfKit.createDefaultDocument();
rtfEdtrKt.read( input, doc, 0 );
input.close();
HTMLEditorKit htmlKit = new HTMLEditorKit();
StringWriter output = new StringWriter();
htmlKit.write( output, doc, 0, doc.getLength());
String html = output.toString();
The main risk in this approach is that the Word engine will either crash or have a memory leak. For this reason you have to have a mechanism for restarting it periodically and testing it to make sure it is functional and not hogging memory.
docx4all is a Swing-based applet which does Word 2007 XML (ie not Word 2003 XML), which we wrote several years ago.
Get it from svn.
That's a possible approach for editing. If all you want is a viewer, which not convert to HTML or PDF? You can use docx4j for that. (Disclosure: "my" project).
You might have a look at the Apache POI - Java API to Handle Microsoft Word Files which is able to read all kinds of word documents (OLE2 and OOXML formats, .doc and .docx extensions respectively).
Reading a doc file can be easy as:
import java.io.*;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.extractor.WordExtractor;
public class ReadDocFile {
public static void main(String[] args) {
File file = null;
WordExtractor extractor = null ;
try {
file = new File("c:\\New.doc");
FileInputStream fis=new FileInputStream(file.getAbsolutePath());
HWPFDocument document=new HWPFDocument(fis);
extractor = new WordExtractor(document);
String [] fileData = extractor.getParagraphText();
for(int i=0;i<fileData.length;i++){
if(fileData[i] != null)
System.out.println(fileData[i]);
}
}
catch(Exception exep){}
}
}
You can find more at: HWPF Quick-Guide (specifically HWPF unit tests)
Note that, according to the POI site:
HWPF is still in early development.
I'd suggest looking at the openoffice source code and implement that.
It's supposed to be written in java.
I have a docx template that I am saving as .xml and then parsing the content.
Then I am generating a new updated word document. After the word document is generated I am unable to open it. It says " document corrupt ". I press ok. Then it says " Press OK if Do you want to retrieve the document ". I press ok. Then I get the updated document. This happens everytime. I have created the same program as stand alone java application. The document generated through the stand alone Java application opens without any errors. Could anyone provide me an insight into this ? I have used the same code for the server side also.
Here is the code that I use to generate the docuemnt.
try {
// Prepare the DOM document for writing
Source source = new DOMSource(doc);
// Prepare the output file
FileOutputStream file = new FileOutputStream(filename);
Result result = new StreamResult(file);
// Write the DOM document to the file
Transformer xformer = TransformerFactory.newInstance()
.newTransformer();
xformer.transform(source, result);
file.close();
} catch (TransformerConfigurationException e) {
System.out.println("Transformation Configuration Excepiton in WriteXMLFile");
} catch (TransformerException e) {
System.out.println("Transformation Excepiton in WriteXMLFile");
} catch (Exception e) {
System.out.println("Transformation Excepiton in WriteXMLFile");
e.printStackTrace();
}
I use POI library to generate Word documents (.doc, not .docx but it should work too).
With POI you can :
- open your word document
- edit whatever you want with a clean API (not mess up in XML)
- write the result
http://poi.apache.org/
You can use POI or docx4j to ensure you create valid Word documents.
Had you check the encoding of JVM?. I had have that problem, and finally I discovered that in Eclipse I had UTF-8, but in standalone I didn't specify encoding, so JVM take ISO-8559.
Please, check it with parameter -Dfile.encoding=UTF-8.
I have used both Apache POI and docx4j extensively, and having said that docx4j is more robust as it offers more support out of the box for not only the document itself but for tables and images. A lot of what docx4j does is automated, where areas Apache's POI you have to do a lot of manual coding for docx support. Unfortunately not much has been done for POI for docx support. I would suggest using docx4j as they have native support for opening and saving a new .docx file out of the box.
