You have imported sun.misc.IOUtils, but you probably wanted org.apache.commons.io.IOUtils. Apache IOUtils has the toString() method you want.
To use it in a maven project, include the following dependency:
<!-- https://mvnrepository.com/artifact/commons-io/commons-io -->
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
Or download the jar-file from project homepage: https://commons.apache.org/proper/commons-io/download_io.cgi

Disable Printing Issue with PDF Box

I am using this sample PDFBox code to encrypt and disable printing of a pdf file. Encryption happens successfully, but printing is not disabled.
What could be the issue?
Here's the dependencies section of my pom.xml
<dependencies>
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>2.0.6</version>
</dependency>
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15</artifactId>
<version>1.46</version>
</dependency>
</dependencies>
and below is the source code
import java.io.File;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.encryption.AccessPermission;
import org.apache.pdfbox.pdmodel.encryption.StandardProtectionPolicy;
public class Test {
public static void main(String[] args) throws Exception {
PDDocument doc = PDDocument.load(new File("/tmp/Test.pdf"));
int keyLength = 128;
AccessPermission ap = new AccessPermission();
ap.setCanPrint(false);
StandardProtectionPolicy spp = new StandardProtectionPolicy("Admin", "Password", ap);
spp.setEncryptionKeyLength(keyLength);
spp.setPermissions(ap);
doc.protect(spp);
doc.save("/tmp/Test-Encrypted.pdf");
doc.close();
}
}

How do I set OAuth2 Google Credentials for Spreadsheet Service?

I took example from here. But my code below gives me "The method setOAuth2Credentials(GoogleCredential) is undefined for the type SpreadsheetService".
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson.JacksonFactory;

SPREADSHEET_FEED_URL = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
File p12 = new File("./key.p12");
HttpTransport httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
String[] SCOPESArray = {"https://spreadsheets.google.com/feeds", "https://spreadsheets.google.com/feeds/spreadsheets/private/full", "https://docs.google.com/feeds"};
final List SCOPES = Arrays.asList(SCOPESArray);
GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(httpTransport)
.setJsonFactory(jsonFactory)
.setServiceAccountId("cliend_ID")
.setServiceAccountScopes(SCOPES)
.setServiceAccountPrivateKeyFromP12File(p12)
.build();
SpreadsheetService service = new SpreadsheetService("Test");
service.setOAuth2Credentials(credential); /////// Error occurs here "The method setOAuth2Credentials(GoogleCredential) is undefined for the type SpreadsheetService"
SpreadsheetFeed feed = service.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class);
List<SpreadsheetEntry> spreadsheets = feed.getEntries();
if (spreadsheets.size() == 0) {
System.out.println("No spreadsheets found.");
}
SpreadsheetEntry spreadsheet = null;
for (int i = 0; i < spreadsheets.size(); i++) {
if (spreadsheets.get(i).getTitle().getPlainText().startsWith("ListOfSandboxes")) {
spreadsheet = spreadsheets.get(i);
System.out.println("Name of editing spreadsheet: " + spreadsheets.get(i).getTitle().getPlainText());
System.out.println("ID of SpreadSheet: " + i);
}
}
}
}
I simply copied the code and imported the libraries as mentioned but I don't understand why I'm getting such error as below.

check that you use correct versions of dependencies:

How to read tibetan content from pdf file?

I have a tibetan pdf file, and I want to extract its content. But I tried following three codes to read the file, I got code that isn't what I wanted.
code1:
import java.io.IOException;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.parser.PdfTextExtractor;
public class iTextReadDemo {
public static void main(String[] args) {
try {
PdfReader reader = new PdfReader("");
String page = PdfTextExtractor.getTextFromPage(reader, 1);
System.out.println("Page Content:\n\n" + page + "\n\n");
} catch (IOException e) {
e.printStackTrace();
}
}
}// - See more at:
// http://www.quicklyjava.com/read-pdf-file-in-java-using-itext/#sthash.iAhF00Kj.dpuf
code2 :
import java.io.FileOutputStream;
import com.lowagie.text.Document;
import com.lowagie.text.PageSize;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.PdfReader;
import com.lowagie.text.pdf.PdfStamper;
import com.lowagie.text.pdf.PdfWriter;
public class MainClass {
public static void main(String[] args) throws Exception {
PdfReader reader = new PdfReader("");
byte[] bs = new byte[100];
byte[] streamBytes = reader.getPageContent(1);
for(byte b: streamBytes){
System.out.print((char)b);
}
}
}
code3:
package pdfBox;
import java.io.BufferedWriter;
import java.io.File;
import java.io.IOException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.util.PDFTextStripper;
public class PDFTest {
public static void main(String[] args) throws Exception {
PDDocument pd;
File input = new File("C:\\Users\\Administrator\\Desktop\\tibetan Dictionary pdf/藏英英藏词典 - 副本.pdf");
pd = PDDocument.load(input);
PDFTextStripper reader = new PDFTextStripper("utf-8");
String pageText = reader.getText(pd);
System.out.println(pageText);
}
}
and this is the part of the maven pom dependency
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.5.3</version>
</dependency>
<dependency>
<groupId>com.lowagie</groupId>

</dependency>
<dependency>
<groupId>org.apache.pdfbox</groupId>

</dependency>
what is wrong ?
is he said right?
https://answers.acrobatusers.com/Can-I-convert-PDF-Word-Doc-Tibetan-script-addition-English-language-q219757.aspx
The quality of exported content from a PDF is directly related to the quality of the PDF's "build" (what is under the hood, not what you "see"). Poor quality export indicates a poorly built PDF. Nothing you can do other that ask the originator of the PDF to do a better job.

GoogleTransport class problem

i'm using a maven project with following dependency :
<dependency>
<groupId>com.google.api.client</groupId>
<artifactId>google-api-client-googleapis-auth-clientlogin</artifactId>
<version>1.2.3-alpha</version>
</dependency>
when i run following code:
import java.io.IOException;
import com.google.api.client.googleapis.GoogleTransport;
import com.google.api.client.googleapis.auth.clientlogin.ClientLogin;
import com.google.api.client.http.HttpRequest;
import com.google.api.client.http.HttpResponseException;
import com.google.api.client.http.HttpTransport;
/**
* Hello world!
*
*/
public class App
{
public static void main( String[] args ) throws IOException
{
HttpTransport transport = GoogleTransport.create();
// transport.addParser(new JsonCParser());
try {
// authenticate with ClientLogin
ClientLogin authenticator = new ClientLogin();
authenticator.authTokenType = "ndev";
authenticator.username = "....";
authenticator.password = "....";
authenticator.authenticate().setAuthorizationHeader(transport);
// make query request
HttpRequest request = transport.buildGetRequest();
request.setUrl("https://www.googleapis.com/bigquery/v1/query");
request.url.put(
"q", "select count(*) from [bigquery/samples/shakespeare];");
System.out.println(request.execute().parseAsString());
} catch (HttpResponseException e) {
System.err.println(e.response.parseAsString());
throw e;
}
}
}
i get below exception:
Exception in thread "main" java.lang.IllegalStateException: Missing required low-level HTTP transport package.
Use package "com.google.api.client.javanet".
at com.google.api.client.http.HttpTransport.useLowLevelHttpTransport(HttpTransport.java:129)
at com.google.api.client.http.HttpTransport.<init>(HttpTransport.java:187)
at com.google.api.client.googleapis.GoogleTransport.create(GoogleTransport.java:58)
at com.example.clientlogin.App.main(App.java:18)
what is the problem with GoogleTransport class?

Quick googeling resulted in maven for com.google.api.client.javanet.nethttpresponse Try adding
<dependency>
<groupId>com.google.api.client</groupId>
<artifactId>google-api-client</artifactId>
<version>1.2.3-alpha</version>
</dependency>
or
<dependency>
<groupId>com.google.api.client</groupId>
<artifactId>google-api-client-javanet</artifactId>
<version>1.2.3-alpha</version>
</dependency>
to your POM file

this question is pretty old, but I've added some updates to our Java Google Client Lib + BigQuery samples (here: http://code.google.com/p/google-bigquery-tools/source/browse/samples/java/gettingstarted/BigQueryJavaGettingStarted/).
