Java: Unzip Folder with subfolders

I am having issue with extracting files into subfolders. The zip files I need to unzip have multiple folders, and I am trying to keep the directory structure when unzipping.
package components;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
/**

*/
public class UnzipUtility {
/**
* Size of the buffer to read/write data
*/
private static final int BUFFER_SIZE = 4096;
/**
* Extracts a zip file specified by the zipFilePath to a directory specified by
* destDirectory (will be created if does not exists)
* #param zipFilePath
* #param destDirectory
* #throws IOException
*/
public void unzip(String zipFilePath, String destDirectory) throws IOException {
File destDir = new File(destDirectory);
if (!destDir.exists()) {
destDir.mkdir();
}
ZipInputStream zipIn = new ZipInputStream(new FileInputStream(zipFilePath));
ZipEntry entry = zipIn.getNextEntry();
// iterates over entries in the zip file
while (entry != null) {
String filePath = destDirectory + File.separator + entry.getName();
if (!entry.isDirectory()) {
// if the entry is a file, extracts it
extractFile(zipIn, filePath);
System.out.println(filePath);
} else {
// if the entry is a directory, make the directory
File dir = new File(filePath);
System.out.println(filePath);
dir.mkdir();
}
zipIn.closeEntry();
entry = zipIn.getNextEntry();
}
zipIn.close();
}
/**
* Extracts a zip entry (file entry)
* #param zipIn
* #param filePath
* #throws IOException
*/
private void extractFile(ZipInputStream zipIn, String filePath) throws IOException {
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(filePath));
byte[] bytesIn = new byte[BUFFER_SIZE];
int read = 0;
while ((read = zipIn.read(bytesIn)) != -1) {
bos.write(bytesIn, 0, read);
}
bos.close();
}
}
The output I get from the code is below. The issue is that it the file DoD-DISA-logos-as-JPEG.jpg is part of a child folder to subfolder. So path should be folder/subfolder/childfolder/DoD-DISA-logos-as-JPEG.jpg. It is not including that childfolder so it gets IO exception I believe.
java.io.FileNotFoundException: /Users/user/Desktop/folder/subfolder/DoD-DISA-logos-as-JPEG.jpg (No such file or directory)

You should not rely on entry.isDirectory() or on the fact that the ZipEntry iterator will list all the folders hierarchies.
A zip files structure may contain only a ZipEntry file wich contains in its name a subfolders hierarchy. Eg. foo/bar/file.txt will be a ZipEntry but not foo/ nor foo/bar/
Thus for :
a file, you should get the parent directory and create the whole hierarchy if it does not exists with File#mkdirs
a directory, you should create the whole hierarchy if it does not exists with File#mkdirs
Your code should be transformed to something like that:
if (!entry.isDirectory()) {
// if the entry is a file, extracts it
new File(filePath).getParentFile().mkdirs();
extractFile(zipIn, filePath);
System.out.println(filePath);
} else {
// if the entry is a directory, make the directory
File dir = new File(filePath);
System.out.println(filePath);
dir.mkdirs();
}
I recommend to use an external library to zip/unzip like zt-zip.

Error while extracting a zip file

I am trying to unzip a compressed folder using java.util.zip package:
Now my compressed folder structure is :
My compressed folder name is classes.zip
Inside this zip folder i have a classes folder inside that i have sub folders as well as files:
If you further go inside the www folder then again it has sub folder which is a java package and inside the package structured folder i have .class files.
Now i am trying to unzip this compressed folder and my code is:
package www.eor.com;
/**
* A console application that tests the UnzipUtility class
*
*/
public class UnzipUtilityTest {
public static void main(String[] args) {
String zipFilePath = "D:/classes.zip";
String destDirectory = "D:/Dojo";
UnzipUtility unzipper = new UnzipUtility();
try {
unzipper.unzip(zipFilePath, destDirectory);
} catch (Exception ex) {
// some errors occurred
ex.printStackTrace();
}
}
}
and the supporting class is :
package www.eor.com;
import java.io.BufferedOutputStream;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

File destDir = new File(destDirectory);
if (!destDir.exists()) {
destDir.mkdir();
}
ZipInputStream zipIn = new ZipInputStream(new FileInputStream(zipFilePath));
ZipEntry entry = zipIn.getNextEntry();
// iterates over entries in the zip file
while (entry != null) {
String filePath = destDirectory + File.separator + entry.getName();
if (!entry.isDirectory()) {
// if the entry is a file, extracts it
extractFile(zipIn, filePath);
} else {
// if the entry is a directory, make the directory
File dir = new File(filePath);
dir.mkdir();
}
zipIn.closeEntry();
entry = zipIn.getNextEntry();
}
zipIn.close();
}
/**

int read = 0;
while ((read = zipIn.read(bytesIn)) != -1) {
bos.write(bytesIn, 0, read);
}
bos.close();
}
}
Now when i run UnzipUtilityTest class it is giving me exception as :
java.io.FileNotFoundException: D:\Dojo\classes\camel-config-xml.xml (The system cannot find the path specified)

at www.cognizant.com.UnzipUtility.unzip(UnzipUtility.java:41)
at www.cognizant.com.UnzipUtilityTest.main(UnzipUtilityTest.java:16)
Why it is giving this exception and how to rectify this problem?

It's probably due to the parent of the file classes/ does not exists, so it can't create a file in it.
When you extract entries of a zip, you have to create the parent folders for the file. A zip does not necessarily contain entries for every single folder. But every entry in zip is of the form path/to/entry/filename.ext so you can derive the parent path of the entry and create the parent folders accordingly.
so before extracting the file, do
new File(filePath).getParent().mkdirs()

how to export a svn repository as zip file in svnkit?

I am trying to export whole repository in zip format .I am not able to find anything related to exporting a folder or repository in svnkit.

I have never tried zipping the whole repository using org.tmatesoft.svnkit. But I have an utility that zips files from a local folder. So if you copy the remote repository locally (into a temp directory), you should be able to zip it using the following class. It needs 2 values, starting folder path and the full, zip file name.

Add files and repertories to a Tar archive with Apache Commons Compress library in non machine dependent way

I'm working on an application that need to create a tar archive in order to calculate his hash.
But I encounter some problems :
the tar is not the same in different machine, then the hash calculated is different
I'm not able to add directories properly
If I add an zip file, at the end, in the tar, I have the content off my zip file :/
I have read different post in SO and the dedicated tutorial on apache, and also the source test code of the apache commons compress jar, but I don't get the right solution.
Are there anybody that can find where my code is not correct ?
public static File createTarFile(File[] files, File repository) {
File tarFile = new File(TEMP_DIR + File.separator + repository.getName() + Constants.TAR_EXTENSION);
if (tarFile.exists()) {
tarFile.delete();
}
try {
OutputStream out = new FileOutputStream(tarFile);
TarArchiveOutputStream aos = (TarArchiveOutputStream) new ArchiveStreamFactory().createArchiveOutputStream("tar", out);
for(File file : files){
Utilities.addFileToTar(aos, file, "");
}
aos.finish();
aos.close();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
return tarFile;
}
private static void addFileToTar(TarArchiveOutputStream tOut, File file, String base) throws IOException {
TarArchiveEntry entry = new TarArchiveEntry(file, base + file.getName());
entry.setModTime(0);
entry.setSize(file.length());
entry.setUserId(0);
entry.setGroupId(0);
entry.setUserName("avalon");
entry.setGroupName("excalibur");
entry.setMode(0100000);
entry.setSize(file.length());
tOut.putArchiveEntry(entry);
if (file.isFile()) {
IOUtils.copy(new FileInputStream(file), tOut);
tOut.closeArchiveEntry();
} else {
tOut.closeArchiveEntry();
File[] children = file.listFiles();
if (children != null) {
for (File child : children) {
addFileToTar(tOut, child, file.getName());
}
}
}
}
Thank you.

I finally found the solution after reading the post of caarlos0 : Encoding problem when compressing files with Apache Commons Compression on Linux
Using the apache-commons-1.8.jar library, I have made a tool class that can do the job :

Thanks for read me.
EDIT : Little correction, I have add the sort of the arrays.
EDIT 2 : I have corrected the code in order to have the same archive on all machine. The hash calculated on the archive is the same everywhere.

How to get raw text from pdf file using java

I have some pdf files, Using pdfbox i have converted them into text and stored into text files, Now from the text files i want to remove
Hyperlinks
All special characters
Blank lines
headers footers of pdf files
“1)”,“2)”, “a)”, “bullets”, etc.
I want to get valid text line by line like this:
We propose OntoGain, a method for ontology learning from multi-word concept terms extracted from plain text. OntoGain follows an ontology learning process dened by distinct processing layers. Building upon plain term extraction a con-cept hierarchy is formed by clustering the extracted concepts. The derived term taxonomy is then enriched with non-taxonomic relations. Several dierent state-of-the-art methods have been examined for implementing each layer. OntoGain is based upon multi-word term concepts, as multi-word or compound terms are vested with more solid and distinctive semantics than plain single word terms. We opted for a hierarchical clustering method and Formal Concept Analysis (FCA) algorithm for building the term taxonomy. Furthermore an association rule algorithm is applied for revealing non-taxonomic relations. A method which tries to carry out the most appropriate generalization level between a relation's concepts is also implemented. To show proof of concept, a system prototype is implemented. The OntoGain allows transformation of the derived ontology into OWL using Jena Semantic Web Frame-work1. OntoGain is applied on two separate data sources a medical and computer corpus and its results are compared with similar results obtained by Text2Onto, a state-of-the-art-ontology learning method. The analysis of 11.5 CCD1.1 results indicates that OntoGain performs better than Text2Onto in terms of precision extracts more correct concepts while being more selective extracts fewer but more reasonable concepts.
How can I achieve this?

Using pdfbox we can achive this
Example :
public static void main(String args[]) {
PDFParser parser = null;
PDDocument pdDoc = null;
COSDocument cosDoc = null;
PDFTextStripper pdfStripper;
String parsedText;
String fileName = "E:\\Files\\Small Files\\PDF\\JDBC.pdf";
File file = new File(fileName);
try {
parser = new PDFParser(new FileInputStream(file));
parser.parse();
cosDoc = parser.getDocument();
pdfStripper = new PDFTextStripper();
pdDoc = new PDDocument(cosDoc);
parsedText = pdfStripper.getText(pdDoc);
System.out.println(parsedText.replaceAll("[^A-Za-z0-9. ]+", ""));
} catch (Exception e) {
e.printStackTrace();
try {
if (cosDoc != null)
cosDoc.close();
if (pdDoc != null)
pdDoc.close();
} catch (Exception e1) {
e1.printStackTrace();
}
}
}

Hi we can extract the pdf files using Apache Tika
The Example is :
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.metadata.TikaCoreProperties;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.sax.BodyContentHandler;
public class WebPagePdfExtractor {
public Map<String, Object> processRecord(String url) {
DefaultHttpClient httpclient = new DefaultHttpClient();
Map<String, Object> map = new HashMap<String, Object>();
try {
HttpGet httpGet = new HttpGet(url);
HttpResponse response = httpclient.execute(httpGet);
HttpEntity entity = response.getEntity();
InputStream input = null;
if (entity != null) {
try {
input = entity.getContent();
BodyContentHandler handler = new BodyContentHandler();
Metadata metadata = new Metadata();
AutoDetectParser parser = new AutoDetectParser();
ParseContext parseContext = new ParseContext();
parser.parse(input, handler, metadata, parseContext);
map.put("text", handler.toString().replaceAll("\n|\r|\t", " "));
map.put("title", metadata.get(TikaCoreProperties.TITLE));
map.put("pageCount", metadata.get("xmpTPg:NPages"));
map.put("status_code", response.getStatusLine().getStatusCode() + "");
} catch (Exception e) {
e.printStackTrace();
} finally {
if (input != null) {
try {
input.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
} catch (Exception exception) {
exception.printStackTrace();
}
return map;
}
public static void main(String arg[]) {
WebPagePdfExtractor webPagePdfExtractor = new WebPagePdfExtractor();
Map<String, Object> extractedMap = webPagePdfExtractor.processRecord("http://math.about.com/library/q20.pdf");
System.out.println(extractedMap.get("text"));
}
}

You can use iText for do such things
//iText imports
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.parser.PdfTextExtractor;
for example:
try {
PdfReader reader = new PdfReader(INPUTFILE);
int n = reader.getNumberOfPages();
String str=PdfTextExtractor.getTextFromPage(reader, 2); //Extracting the content from a particular page.
System.out.println(str);
reader.close();
} catch (Exception e) {
System.out.println(e);
}
another one
try {
PdfReader reader = new PdfReader("c:/temp/test.pdf");
System.out.println("This PDF has "+reader.getNumberOfPages()+" pages.");
String page = PdfTextExtractor.getTextFromPage(reader, 2);
System.out.println("Page Content:\n\n"+page+"\n\n");
System.out.println("Is this document tampered: "+reader.isTampered());
System.out.println("Is this document encrypted: "+reader.isEncrypted());
} catch (IOException e) {
e.printStackTrace();
}
the above examples can only extract the text, but you need to do some more to remove hyperlinks, bullets, heading & numbers.
