Team - I am trying to add all the necessary dependencies to my OSGi-compatible application so that I can use Flying Saucer. I have read the Getting Started section on the Flying Saucer GitHub page and added the list of dependencies that are listed, but my application is still generating empty PDFs. I think I may be using the wrong dependencies. Could you please tell me all the required Maven dependencies for Flying Saucer?

Here my the POM dependencies

 <dependency>
     <groupId>org.xhtmlrenderer</groupId>
     <artifactId>flying-saucer-pdf-itext5</artifactId>
     <version>9.2.2</version>
     <scope>provided</scope>
 </dependency>

 <dependency>
     <groupId>org.xhtmlrenderer</groupId>
     <artifactId>flying-saucer-pdf</artifactId>
     <version>9.2.2</version>
     <scope>provided</scope>
 </dependency>

 <dependency>
     <groupId>com.apple</groupId>
     <artifactId>AppleJavaExtensions</artifactId>
     <version>1.4</version>
     <scope>provided</scope>
 </dependency>

<dependency>
     <groupId>com.lowagie</groupId>
     <artifactId>itext</artifactId>
     <version>4.2.0</version>
     <scope>provided</scope>
 </dependency>
 <dependency>
     <groupId>com.itextpdf</groupId>
     <artifactId>itextpdf</artifactId>
     <version>5.5.6</version>
     <scope>provided</scope>
 </dependency>

 <dependency>
     <groupId>org.apache.santuario</groupId>
     <artifactId>xmlsec</artifactId>
     <version>4.0.0-M1</version>
     <scope>provided</scope>
 </dependency>

Java code

import org.w3c.dom.Document;
import org.xhtmlrenderer.pdf.ITextRenderer;
import org.xml.sax.InputSource;

// Create an ITextRenderer instance
 ITextRenderer renderer = new ITextRenderer();

 // Convert the InputStream to a String
// String htmlContent = convertInputStreamToString(urlInputStream);
 String htmlContent = "<!DOCTYPE html><html><body><h1>My First Heading</h1><p>My first paragraph.</p></body></html>";

 // Set the HTML content as the document ////////////
 renderer.setDocumentFromString(htmlContent);

 // Render to PDF
 ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
 renderer.layout();
 renderer.createPDF(outputStream);
 renderer.finishPDF();

Hi Ezhil!

Are you sure you are not catching and hiding the exception?

When I created a new project with the same dependencies as you described, I got the following error:

java.lang.ClassNotFoundException: com.itextpdf.text.DocumentException

When I removed "<scope>provided</scope>" from all dependencies,

I got a correct PDF with text "My First Heading My first paragraph."
