Docx to Pdf Converter in java

The below code is not working with Apache poi 3.16.
Can someone provide with the correct solution, in my project there are some dependency for using only
public void ConvertToPDF(String docPath, String pdfPath) {
try {
InputStream doc = new FileInputStream(new File(docPath));
XWPFDocument document = new XWPFDocument(doc);
PdfOptions options = PdfOptions.create();
OutputStream out = new FileOutputStream(new File(pdfPath));
PdfConverter.getInstance().convert(document, out, options);
System.out.println("Done");
} catch (FileNotFoundException ex) {
System.out.println(ex.getMessage());
} catch (IOException ex) {
System.out.println(ex.getMessage());
}
}
Exception:

The main problem with this is that those PdfOptions and PdfConverter are not part of the apache poi project. They are developed by opensagres and first versions were badly named org.apache.poi.xwpf.converter.pdf.PdfOptions and org.apache.poi.xwpf.converter.pdf.PdfConverter. Those old classes were not updated since 2014 and needs version 3.9 of apache poi to be used.
Do using the much more current fr.opensagres.poi.xwpf.converter.pdf, which works using the latest stable release apache poi 3.17.
Then do
import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.File;
//needed jars: fr.opensagres.poi.xwpf.converter.core-2.0.1.jar,
// fr.opensagres.poi.xwpf.converter.pdf-2.0.1.jar,
// fr.opensagres.xdocreport.itext.extension-2.0.1.jar,
// itext-2.1.7.jar
import fr.opensagres.poi.xwpf.converter.pdf.PdfOptions;
import fr.opensagres.poi.xwpf.converter.pdf.PdfConverter;
//needed jars: apache poi and it's dependencies
import org.apache.poi.xwpf.usermodel.XWPFDocument;
public class DOCXToPDFConverterSampleMin {
public static void main(String[] args) throws Exception {
String docPath = "./WordDocument.docx";
String pdfPath = "./WordDocument.pdf";
InputStream in = new FileInputStream(new File(docPath));
XWPFDocument document = new XWPFDocument(in);
PdfOptions options = PdfOptions.create();
OutputStream out = new FileOutputStream(new File(pdfPath));
PdfConverter.getInstance().convert(document, out, options);
document.close();
out.close();
}
}
October 2018:
This code works using apache poi 3.17. It cannot work using apache poi 4.0.0 due to changings in apache poi which were not taken in account in fr.opensagres.poi.xwpf.converter until now.
February 2019:
Works for me now using the newest apache poi version 4.0.1 and the newest version 2.0.2 of fr.opensagres.poi.xwpf.converter.pdf and consorts.
June 2021:
Works using apache poi version 4.1.2 and the newest version 2.0.2 of fr.opensagres.poi.xwpf.converter.pdf and consorts.
Cannot work using apache poi version 5.0.0 because XDocReport needs ooxml-schemas which apache poi 5 does not support anymore.
April 2022:
Works using apache poi version 5.2.2 and the newest version 2.0.3 of fr.opensagres.poi.xwpf.converter.pdf and consorts.

New version 2.0.2 of fr.opensagres.poi.xwpf.converter.core runs with apache poi 4.0.1 and itext 2.17.
You just need to add below dependency in Maven and then maven will auto download all dependent dependencies. (Updated your Maven project, so it downloaded all these libraries and all of its dependencies)
<dependency>
<groupId>fr.opensagres.xdocreport</groupId>
<artifactId>fr.opensagres.poi.xwpf.converter.pdf</artifactId>
<version>2.0.2</version>
</dependency>

June 2021: Works using apache poi version 4.1.2 and the newest version
2.0.2 of fr.opensagres.poi.xwpf.converter.core and consorts. Cannot work using apache poi version 5.0.0 because XDocReport needs
ooxml-schemas which apache poi 5 does not support anymore.
ooxml-schemas has been replaced with poi-ooxml-full.
https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-full/5.0.0
but it doesn't work with fr.opensagres.poi.xwpf.converter.core 2.0.2, because is not compatible with new version of CTStyle which is included in apache-poi 5.0.0.

Apache POI - how to create workbook for xlsx

When working with just xls I can create workbooks just fine, however when working with xlsx I cant seem to get it to work.
I am using the poi-ooxml.jar and am trying to use the command
new XSSFWorkbook();
However I get an error message everytime, any thoughts?

Apache POI Dependency and Component . You might be missing:
For poi-ooxml you need it's dependencies
poi,
poi-ooxml-schemas
dom4j
poi-ooxml-version-yyyymmdd.jar
Although Not related to your question try to search for stacktrace:
Caused by: java.lang.ClassNotFoundException: org.apache.poi.ss.usermodel.Workbook
This will help you in long run.

You need to add extra 2 jars to make POI work on (.xlsx) Excel file.
1.first you need to import all the jar poi-3.9
2.Add xmlbeans2.3.0.jar and dom4j-1.6.jar to your classpath. These 2 jars are the dependency jars for handling .xlsx Excel file in POI Library.
Maven project add below dependency
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.9</version>
</dependency>
so programming for creating exls sheet
package com.loknath.lab;
import java.io.FileOutputStream;
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRichTextString;
import org.apache.poi.hssf.usermodel.HSSFRow;

public class ReadWriteXL
{
public static void main(String[] args) throws InvalidFormatException, IOException{
System.out.println("Write data to an Excel Sheet");
FileOutputStream fos=new FileOutputStream("D:/temp/1.xlsx");
HSSFWorkbook workBook = new HSSFWorkbook();
HSSFSheet spreadSheet = workBook.createSheet("email");
HSSFRow row;
HSSFCell cell;
for(int i=0;i<arr.size();i++){
row = spreadSheet.createRow((short) i);
cell = row.createCell(i);
cell.setCellValue("string value added");
}
workBook.write(fos);
}
}}

I think you would need to download the binary distribution from http://poi.apache.org/download.html
Add the jars into your libraries and it should resolve the error
Be sure to add all the jars not just the poi-ooxml

JAR fails to load com.microsoft.sqlserver.jdbc.sqlserverdriver

There seems to be a number of similar questions related to this, but none have been able to provide me with any help. I'm running Microsoft's JDBC driver on SQL Server (I am using sqljdbc4.jar) and using integrated authentication to access my database. The code snippet for connecting is as follows:
String connectionUrl="jdbc:sqlserver://servername:1433;integratedSecurity=true;";
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection(connectionUrl);
}//catch, etc...
When I run the project in Eclipse, it starts up without a hitch. When I run Maven clean install and pack it into a .jar, however, I get the error:
java.lang.ClassNotFoundException: Failure to load: com.microsoft.sqlserver.jdbc.SQLServerDriver

I have attempted the solutions posted in other threads; I have a System CLASSPATH variable that directs to the .jar and it is located in my build path and my runtime classpath. Perhaps the problem is staring me in the face. My best guess is that it is related to Maven, but how should I go about solving this?
Also, please let me know if I need to clarify any points; I'd be more than happy to do so.

In your comment you confirm that you manually added it to the build path and not to the maven POM. You really need to add a dependency, otherwise Maven won't know about it when building.
And add the dependency to the POM:
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>8.1.1.jre8</version>
</dependency>

Can't make Executable JAR file with library in Eclipse

I'm trying to export my project as executable jar, and all is good except one thing: there are 2 windows - the first is main jframe and second is jframe for making 3D surfaces using jzy3d library; the first window contains button "Show" for executing the second jframe. When I execute this project in Eclipse it works good, but when I make executable jar it is executed, but if I click by "Show" button the second jframe doesn't open. So, please, tell me, how can I fix it?

Probaly on command line you did not specify the classpath for jzy3d library
You can run a jar file with lib:
"java -cp libs/* -jar program.jar"
where you put your lib (jzy3d.jar) in the libs folder
If you have used some special tool that creates an executable jar file,
then you have to configure that tool to include the jzy3d.jar lib to be used inside the exe.

You'll need to do one of the following:
repack the contents of each jarfile dependency in your own executable jarfile
use an .exe wrapper such as Launch4j to pack your jarfiles into a self-extracting-and-launching executable
include the jarfile dependencies in the Class-Path attribute of your MANIFEST.MF when creating the executable jarfile from Eclipse, and include those dependencies in the appropriate relative location when you distribute your application
Of the above options, 1 might be the easiest and most convenient for you. If you extract the contents of the jarfile dependencies into an Eclipse project, it is then very easy to include those resources when you create your jarfile using Eclipse's wizard.
Options 2 and 3 are also pretty straightforward but I would recommend making an ant script so you can have a 1-click build.

Exe4J return Exception "?

I am using exe4j and I'm trying generate an exe file, after generated I try execute but does not work.

Any idea?

It looks like you are missing a joda-time class. My only thought might be that you are missing the library for it, which can be downloaded here:
http://joda-time.sourceforge.net/
Or, if you use maven like me, add:
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>2.0</version>
</dependency>
to your POM file.
Hope this helps!

It looks like you left a library out of your executable. It can't find the org.joda.time package.
There are 2 probable solutions:
If the library got left out, add it.
If the library is already included, check that the classpath shows where it is.
Here is the exe4j help page that shows how to edit the classpath.
