I am new to JSP but decided to give this a try anyway. First, I had to install the Apache Tomcat Server.

Install Apache Tomcat Server

1. Installed Oracle JDK.
2. Created a system-wide environment variable named JAVA_HOME for the JDK installation folder.
3. Downloaded Apache Tomcat Server for Windows.
4. Extracted the main Tomcat folder from inside the ZIP archive to my C:\ drive. Installation over.
5. Created system-wide environment variable CATALINA_HOME with the path to the Tomcat folder.
   
6. Created a "Limited User" Windows account and ran bin\startup.bat file using this account. (I am still on XP and my regular account is a full-blown Admnistrator account.)
   
7. Tested the default site at http://localhost:8080.
   

Next, I had to create a JSP script that used PDFOne to create a new PDF document and send it down to the browser.

Create PDFOne (for Java™) JSP Application

1. Created a new folder named lib in the C:\apache-tomcat-7.0.14\webapps\ROOT\WEB-INF for the PDFOne JAR files.
2. Copied the following files to the folder.
   1. bcprov-jdk14.jar
   2. PDFOne.jar
   3. pdfonejfont.dll
3. Stopped and restarted the Tomcat server.
4. Created a new JSP script at C:\apache-tomcat-7.0.14\webapps\ROOT\test.jsp with the following content.

   <%@page import="com.gnostice.pdfone.PDFOne" %>
   <%@page import="com.gnostice.pdfone.PdfDocument" %>
   <%@page import="com.gnostice.pdfone.fonts.PdfFont" %>
   <%@page import="java.awt.Color" %>
   <%
     // Activate your license
     PDFOne.activate("your-pdfone-activation-key",
                     "your-pdfone-product-key");
     try {
       // Create a new PDF document
       PdfDocument doc = new PdfDocument();
    
       // Access the default font and modify it
       PdfFont defaultFont = doc.getFont();
       defaultFont.setStyle(PdfFont.STROKE_AND_FILL);
       defaultFont.setSize(60);
       defaultFont.setStrokeColor(Color.RED);
       defaultFont.setStrokeWidth(2);
       defaultFont.setColor(Color.YELLOW);
   
       // Prepare the browser
       response.setContentType("application/pdf");
       response.setBufferSize(2000);
   
       // Set PDF version to 1.4 for backward compatibility
       doc.setVersion(PdfDocument.VERSION_1_4);
   
       // Render text on the first page
       doc.writeText("Hello, World!", 100, 100);
   
       // Save the document to the browser
       doc.save(response.getOutputStream());
   
       // Close the document
       doc.close();
   
       // Close the browser output
       response.flushBuffer();
     } catch (Exception e) {
       out.println("Sorry, an error occurred " + e.getMessage() );
     } 
   %>

5. Accessed the JSP script in a browser.
