Please check the code suggest correction:

}
}
The code is to fetch the data from excel sheet and login automatically.But I am getting an error--
"Exception in thread "main" java.lang.NullPointerException: Cannot invoke "org.apache.poi.ss.usermodel.Workbook.getSheet(String)" because "loginWorkbook" is "null"
at com.framework.DataDriveFramework.readExcel(DataDriveFramework.java:31)
at com.framework.DataDriveFrame.main(DataDriveFrame.java:60)"

You missed a dot '.' in the below line in readExcel() method:
else if(fileExtension.equals("xls"))
it should be like:
else if(fileExtension.equals(".xls"))

Can i take a screenshot and paste it in a word file in appium using Java?

I'm currently using the below method to take screenshots and store them in a folder called 'Screenshots'. But what i want is, to take these screenshots and paste them in a word document according to the test cases to which they belong.
Is it possible? If so could somebody please guide me?
public String FailureScreenshotAndroid(String name) {
try {
Date d = new Date();
String date = d.toString().replace(":", "_").replace(" ", "_");
TakesScreenshot t = (TakesScreenshot)driver;
File f1 = t.getScreenshotAs(OutputType.FILE);//Temporary Location
String permanentLocation =System.getProperty("user.dir")+ "\\Screenshots\\"+name+date+".png";
File f2 = new File(permanentLocation);
FileUtils.copyFile(f1, f2);
return permanentLocation;
}catch (Exception e) {
String msg = e.getMessage();
return msg;
}
}

Try below:

Unprotect word document using java

how can we unprotect the word document using java apache poi? I have protected the document as read-only using password pro-grammatically.Now I want to unprotect it. How can we do ? Is there any method to unprotect the document. I have used removePasswordProtection() but that document is not editable even after using that method.
The sample code that I have used for protection is
XWPFDocument document=new XWPFDocument();
document.enforceReadonlyProtection(strPassword,HashAlgorithm.sha1);
The document is getting protected successfully.
But when I am unprotecting document using the below code snippet it is not working.
if(document.isEnforcedReadonlyProtection())
{
if(document.validateProtectionPassword(strPassword))
{
document.removeProtectionEnforcement();
}
}
Can anyone help me what method that I can use to unprotect the document?

Cannot reproducing.
Following code produces two Word documents. One, WordProtected.docx, which is protected and one, WordUnprotected.docx in which protection is removed.
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;
import org.apache.poi.poifs.crypt.HashAlgorithm;
class XWPFReadOnlyProtection {
public static void main(String[] args) throws Exception {
XWPFDocument document = new XWPFDocument();
String strPassword = "password";
document.enforceReadonlyProtection(strPassword, HashAlgorithm.sha1);
FileOutputStream fileout = new FileOutputStream("WordProtected.docx");
document.write(fileout);
fileout.close();
document.close();
document = new XWPFDocument(new FileInputStream("WordProtected.docx"));
document.removeProtectionEnforcement();
fileout = new FileOutputStream("WordUnprotected.docx");
document.write(fileout);
fileout.close();
document.close();
}
}

use this code for Word to Protect
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.hssf.record.crypto.Biff8EncryptionKey;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
public class WordTest {
public static void main(String[] args) throws IOException {
FileInputStream in = new FileInputStream("D:\\govind.doc");
BufferedInputStream bin = new BufferedInputStream(in);
POIFSFileSystem poiFileSystem = new POIFSFileSystem(bin);
Biff8EncryptionKey.setCurrentUserPassword("P#ssw0rd");
HWPFDocument doc = new HWPFDocument(poiFileSystem);
Range range = doc.getRange();
FileOutputStream out = new FileOutputStream("D:\\govind.doc");
doc.write(out);
out.close();
}
}
this is use for protected word File unportected

import java.io.FileInputStream;

How to add digital signature to Excel and JPG files?

I am using below code to generate and add digital signatures to the Excel file:
SignedObject signedHashObject =null;
signatureConfig.setKey((PrivateKey) privateKey);signatureConfig.setSigningCertificateChain(Collections.singletonList(Util.getX509Certificate(certificateAlias)));
OPCPackage pkg = OPCPackage.open(selectedFileName, PackageAccess.READ_WRITE);
signatureConfig.setOpcPackage(pkg);
SignatureInfo si = new SignatureInfo();
si.setSignatureConfig(signatureConfig);
si.confirmSignature();
pkg.close();
Here the private key is java.security.mscapi.rsaprivatekey.
After fixing all the version compatibility issues, I am stuck with the below error,
The specified key of type sun.security.mscapi.RSAPrivateKey is not an RSAPrivateKey

I've fixed this now via #62159.
Make sure to set -Dorg.apache.xml.security.ignoreLineBreaks=true in the JVM properties.
Complete example, i.e. my test code:

Printing results from PDF box output to a text file

I am working on a class which Parses a PDF document with PDF Box, its purpose is to create a text file (its name is PdfTestFile.txt) with the results. We have gotten it to print the parsed text to the console, but I don't know how to make it write the results to the .txt file that the class creates (name is PdfTestFile.txt).
I tried to use out.print(Text); but it gives me an error saying that:
out cannot be resolved
The class PdfEasyManager calls the class EasySearch in which we see the error mentioned above.
Below is the code that I have where the String Text is what I would like to print to the file PdfTestFile.txt:
Class " PdfEasyManager":
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.BufferedWriter;

import java.io.PrintWriter;
public class PdfEasyManager {
static BufferedWriter writer;
public static void main(String[] args) throws IOException {
//writer = new BufferedWriter(new FileWriter("Evergreen.txt"));
EasySearch easysearch = new EasySearch();
// pdfManager.setFilePath("PDFextTEST.pdf");
System.out.println(easysearch.ToText());
//out.println(easysearch.ToText());
}
}
Class "EasySearch" :

{
this.pdfStripper = null;
this.pdDoc = null;
this.cosDoc = null;
writer = new BufferedWriter(new FileWriter("PdfTestFile.txt"));
file = new File("C:/Users/Jon Smith/Desktop/Sample.pdf");
parser = new PDFParser(new FileInputStream(file));
parser.parse();
cosDoc = parser.getDocument();
pdfStripper = new PDFTextStripper();
pdDoc = new PDDocument(cosDoc);
pdDoc.getNumberOfPages();
pdfStripper.setStartPage(1);// reading text from page 1
// pdfStripper.setEndPage(10);// to 10
pdfStripper.setEndPage(pdDoc.getNumberOfPages());// if you want to get text from full pdf file use this code
Text = pdfStripper.getText(pdDoc);
out.print(Text); //this is the line that gives me the error
return Text;
}
public void setFilePath(String filePath) {
this.filePath = filePath;
}
}

You are using out which is not present in your class. Use System.out.print(Text).

Thanks for the help but
writer.write(Text);
solves the issue I was having
