JSF Primefaces p:fileDownload file name contains UTF-8 characters

I am working on Java 8, JSF 2, Primefaces 5.1.
Conversation to PDF or Docx works, but when I am displaying file name, it just skips UTF-8 encoded letters, in my case, Lithuanian letters like ą,č,ę,ė,į,š,ų,ū
What I have tried so farm is :
<h:form enctype="multipart/form-data;charset=UTF-8">
Charset.forName("UTF-8").encode(myString)
or
byte[] bytes = templateTitle.getBytes(Charset.forName("UTF-8"));
String title = new String(bytes, Charset.forName("UTF-8"));
or
UTF-8 text is garbled when form is posted as multipart/form-data
checked some tuttorials about encoding, still, no use,
also checked this, but I just do not understand this example...
Primefaces fileDownload non-english file names corrupt
my code:
Download file as docx
public void downloadTemplateAsDocx() throws Exception {
try {
InputStream content = null;
String objID = this.actData.getMainActs().get(0).getId();
ContentStream cmisStream = folderCatalogue.getDocumentContentStream(objID);
content = cmisStream.getStream();
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage();
AlternativeFormatInputPart afiPart = new AlternativeFormatInputPart(new PartName("/hw.html"));
afiPart.setBinaryData(content);
afiPart.setContentType(new ContentType("text/html"));
Relationship altChunkRel = wordMLPackage.getMainDocumentPart().addTargetPart(afiPart);
CTAltChunk ac = Context.getWmlObjectFactory().createCTAltChunk();
ac.setId(altChunkRel.getId());
wordMLPackage.getMainDocumentPart().addObject(ac);
wordMLPackage.getContentTypeManager().addDefaultContentType("html", "text/html");
File fileTmp = File.createTempFile("tempDocFile", "docx");
wordMLPackage.save(fileTmp);
streamedContent = new DefaultStreamedContent(new FileInputStream(fileTmp), cmisStream.getMimeType(),
templateTitle + ".docx", "UTF-8");
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (InvalidFormatException eInv) {
eInv.printStackTrace();
} catch (IOException ioEx) {
ioEx.printStackTrace();
} catch (Docx4JException docxEx) {
docxEx.printStackTrace();
}
}
code for .Pdf file download.
public void downloadTemplateAsPdf() {
try {
InputStream content = null;
String objID = this.actData.getMainActs().get(0).getId();
ContentStream cmisStream = folderCatalogue.getDocumentContentStream(objID);
content = cmisStream.getStream();
File fileTmp = File.createTempFile("tempFile", "pdf");
OutputStream fileStream = new FileOutputStream(fileTmp);
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, fileStream);
document.open();
XMLWorkerHelper worker = XMLWorkerHelper.getInstance();
worker.parseXHtml(writer, document, content, Charset.forName("UTF-8"));
document.close();
fileStream.close();
streamedContent = new DefaultStreamedContent(new FileInputStream(fileTmp), cmisStream.getMimeType(),
templateTitle + ".pdf");
} catch (FileNotFoundException e) {
e.printStackTrace();
System.out.println("File was not found");
} catch (IOException ex) {
ex.printStackTrace();
} catch (Exception exeption) {
exeption.printStackTrace();
}
}
EDIT:
<p:fileDownload value="#{controller.streamedContent}" />
private StreamedContent streamedContent;

Solution,
String title = URLEncoder.encode(templateTitle, "UTF-8");
StringBuilder fileName = new StringBuilder(title);
if (title.contains("+")) {
for (int i = 0; i < title.length(); i++) {
if (title.charAt(i) == '+') {
fileName.setCharAt(i, ' ');
}
}
}
This Encoding works fine, just it replaces all spaces to + that's why I loop over it.

Create a new Pdf from an existing Pdf and (HTML + CSS)

My use case is that I am generating pdf on the fly. Also I have a pdf with single page. I want to concatenate the newly generated PDF after/before the existing pdf page.
I was already able to generate PDF from HTML (this may result in 2-3 pages) Pdf from HTML with CSS
I tried looking up at the examples one of which is to concatenate existing PDFs pagewise Working with existing PDFs - Concatenate

This page shows exactly what you request with prepend and append static PDF with composed HTML and CSS content.

How to read .doc file line by line in java using all necessary jar file?

I want to display the difference between two .doc files line by line. I have done it with .txt files and it is working perfect. For this purpose I used the following code:
FileReader File1Reader = new FileReader(File1.getPath());
FileReader File2Reader = new FileReader(File2.getPath());
// Create Buffered Object.
BufferedReader File1BufRdr = new BufferedReader(File1Reader);
BufferedReader File2BufRdr = new BufferedReader(File2Reader);
// Get the file contents into String Variables.
String File1Content = File1BufRdr.readLine();
String File2Content = File2BufRdr.readLine();
//New String Builder
StringBuilder buffer = new StringBuilder();
Is there any way to read the doc files line by line.
I'm using following following code to read from doc file but this is not line by line. Here is the code:
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.extractor.WordExtractor;
public class read_From_Doc_Docx {
public static void main(String[] args) {
//Alternate between the two to check what works.
//String FilePath = "D:\\Users\\username\\Desktop\\Doc1.docx";
String FilePath = "/Users/esna786/Removal of Redundancy.docx";
FileInputStream fis;
if (FilePath.substring(FilePath.length() - 1).equals("x")) { //is a docx
try {
fis = new FileInputStream(new File(FilePath).getAbsolutePath());
XWPFDocument doc = new XWPFDocument(fis);
XWPFWordExtractor extract = new XWPFWordExtractor(doc);
System.out.println(extract.getText());
} catch (IOException e) {
e.printStackTrace();
}
} else { //is not a docx
try {
fis = new FileInputStream(new File(FilePath));
HWPFDocument doc = new HWPFDocument(fis);
WordExtractor extractor = new WordExtractor(doc);
System.out.println(extractor.getText());
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

Just use getParagraphText() method instead of getText().

Yes,i have seen many posts about this error. Still i couldnt find the solution to read this file.
Thanks
file.pdf
This is my code:
static String pdftoText(String fileName) throws IOException {
PDFParser parser;
String parsedText = null;;
PDFTextStripper pdfStripper = new PDFTextStripper();
PDDocument pdDoc = null;
COSDocument cosDoc = null;
File file = new File(fileName);
if (!file.isFile()) {
System.err.println("File " + fileName + " does not exist.");
return null;
}
try {
parser = new PDFParser(new FileInputStream(file));
} catch (IOException e) {
System.err.println("Unable to open PDF Parser. " + e.getMessage());
return null;
}
try {
parser.parse();
cosDoc = parser.getDocument();
pdfStripper = new PDFTextStripper();
pdfStripper.setSuppressDuplicateOverlappingText(false);
pdDoc = new PDDocument(cosDoc);
int endPage=pdDoc.getPageCount();
if(endPage>300)
endPage=300;
pdfStripper.setStartPage(1);
pdfStripper.setEndPage(endPage);
parsedText = pdfStripper.getText(cosDoc);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (cosDoc != null)
cosDoc.close();
if (pdDoc != null)
pdDoc.close();
} catch (Exception e) {
e.printStackTrace();
}
}
return parsedText;
}

This one works
static String pdftoText(String fileName) throws IOException {
String parsedText = null;;
PDFTextStripper pdfStripper = new PDFTextStripper();
PDDocument pdDoc = null;
File file = new File(fileName);
if (!file.isFile()) {
System.err.println("File " + fileName + " does not exist.");
return null;
}
try {
pdDoc=PDDocument.loadNonSeq(file, null);
} catch (IOException e) {
System.err.println("Unable to open PDF Parser. " + e.getMessage());
return null;
}
try {
pdfStripper = new PDFTextStripper();
int endPage=pdDoc.getPageCount();
if(endPage>300)
endPage=300;
pdfStripper.setStartPage(1);
pdfStripper.setEndPage(endPage);
parsedText = pdfStripper.getText(pdDoc);
System.out.println(parsedText);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (pdDoc != null)
pdDoc.close();
} catch (Exception e) {
e.printStackTrace();
}
}
return parsedText;
}

How to read raw text from pdf file using java [duplicate]

I need to extract text (word by word) from a pdf file.
import java.io.*;
import com.itextpdf.text.*;
import com.itextpdf.text.pdf.*;
import com.itextpdf.text.pdf.parser.*;
public class pdf {
private static String INPUTFILE = "http://ontology.buffalo.edu/ontology%28PIC%29.pdf" ;
private static String OUTPUTFILE = "c:/new3.pdf";
public static void main(String[] args) throws DocumentException,
IOException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document,
new FileOutputStream(OUTPUTFILE));
document.open();
PdfReader reader = new PdfReader(INPUTFILE);
int n = reader.getNumberOfPages();
PdfImportedPage page;
// Go through all pages
for (int i = 1; i <= n; i++) {
page = writer.getImportedPage(reader, i);
System.out.println(i);
Image instance = Image.getInstance(page);
document.add(instance);
}
document.close();
PdfReader readerN = new PdfReader(OUTPUTFILE);
PdfTextExtractor parse = new PdfTextExtractor();
for (int i = 1; i <= n; i++)
System.out.println(parser.getTextFromPage(reader,i));
}
When I compile the code, I have this error:
the constructor PdfTextExtractor is undefined
How do I fix this?

PDFTextExtractor only contains static methods and the constructor is private. itext
You can call it like so:
String myLine = PDFTextExtractor.getTextFromPage(reader, pageNumber)

If you want to get all the text from the PDF file and save it to a text file you can use below code.
Use pdfutil.jar library.
import java.io.IOException;
import java.io.PrintWriter;
import com.testautomationguru.utility.PDFUtil;
public class PDFToText{
public static void main(String[] args) {
try {
String pdfFilePath = "C:\\abc.pdf";
PDFUtil pdfUtil = new PDFUtil();
String content = pdfUtil.getText(pdfFilePath);
PrintWriter out = new PrintWriter("C:\\abc.txt");
out.println(content);
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
