If so could you please post the url as a comment, I will only award the
100 points "graded A" if the full source code is posted here and that
it works with J++.

Normal text doesn't comprize any formatting statements such as bold, italic, headings, and
so on. Obviously, these statements will not magically appear in the conversion. All that you
will get is a flat text, as the original, but "converted" in an HTML file. The way to do this is
to enclose the text into the adequate HTML tags and use pre-formatting so that the end
of lines are treated as true end of lines (by default, end of lines are ignored in HTML).

Here is a sample, tested, implementation, written in 100% pure Java:

import java.io.*;

public class Txt2Html {

    public Txt2Html(String file) {
        try {
            FileInputStream  in  = new FileInputStream(file);
   
            FileOutputStream out = new FileOutputStream(file + ".html");
            out.write("<html>\n".getBytes()); // begin of HTML file
            out.write("<body>\n".getBytes()); // begin of the body of the page
            out.write("<pre>".getBytes()); // use pre-formatted text

            byte buffer[] = new byte[1000];

            int count=0;
            while((count=in.read(buffer)) > -1) {
                out.write(buffer,0,count);
            }

            out.write("</pre>".getBytes());  // end of pre-formatted text      
            out.write("</body>".getBytes()); // end of body
            out.write("</html>".getBytes()); // end of HTML
   
            in.close();
            out.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    // example of usage: java Txt2Html mytext.txt
    public static void main(String args[]) {
        Txt2Html converter = new Txt2Html(args[0]);
        return;
    }

}

Fontaine,
In J++, the following was produced.

C:\Administrator\Temp\Txt2Html.java(10,47) : error J0078: Class 'String' doesn't have a method that matches 'getBytes()'
C:\Administrator\Temp\Txt2Html.java(11,47) : error J0078: Class 'String' doesn't have a method that matches 'getBytes()'
C:\Administrator\Temp\Txt2Html.java(12,44) : error J0078: Class 'String' doesn't have a method that matches 'getBytes()'
C:\Administrator\Temp\Txt2Html.java(21,45) : error J0078: Class 'String' doesn't have a method that matches 'getBytes()'
C:\Administrator\Temp\Txt2Html.java(22,46) : error J0078: Class 'String' doesn't have a method that matches 'getBytes()'
C:\Administrator\Temp\Txt2Html.java(23,46) : error J0078: Class 'String' doesn't have a method that matches 'getBytes()'
Error executing jvc.exe.

Txt2Html - 6 error(s), 0 warning(s)

Then when I have the getBytes(), it produced this!

C:\Administrator\Temp\Txt2Html.java(10,20) : error J0078: Class 'FileOutputStream' doesn't have a method that matches 'write(String)'
C:\Administrator\Temp\Txt2Html.java(11,20) : error J0078: Class 'FileOutputStream' doesn't have a method that matches 'write(String)'
C:\Administrator\Temp\Txt2Html.java(12,20) : error J0078: Class 'FileOutputStream' doesn't have a method that matches 'write(String)'
C:\Administrator\Temp\Txt2Html.java(21,20) : error J0078: Class 'FileOutputStream' doesn't have a method that matches 'write(String)'
C:\Administrator\Temp\Txt2Html.java(22,20) : error J0078: Class 'FileOutputStream' doesn't have a method that matches 'write(String)'
C:\Administrator\Temp\Txt2Html.java(23,20) : error J0078: Class 'FileOutputStream' doesn't have a method that matches 'write(String)'
Error executing jvc.exe.

Txt2Html - 6 error(s), 0 warning(s)

Please review your code, am I missing anything?

Visibly, J++ doesn't support JDK 1.1. Here is an equivalent, using only JDK 1.0 methods:

import java.io.*;

public class Txt2Html {

    public Txt2Html(String file) {
        try {
            FileInputStream  in  = new FileInputStream(file);
   
            FileOutputStream out = new FileOutputStream(file + ".html");
            out.write(getBytes("<html>\n"));
            out.write(getBytes("<body>\n"));
            out.write(getBytes("<pre>"));

            byte buffer[] = new byte[1000];

            int count=0;
            while((count=in.read(buffer)) > -1) {
                out.write(buffer,0,count);
            }

            out.write(getBytes("</pre>"));        
            out.write(getBytes("</body>"));
            out.write(getBytes("</html>"));
   
            in.close();
            out.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    public byte[] getBytes(String text) {
        byte txt[] = new byte[text.length()];
        text.getBytes(0,text.length(),txt,0);
        return txt;
    }

    // example of usage: java Txt2Html mytext.txt
    public static void main(String args[]) {
        Txt2Html converter = new Txt2Html(args[0]);
        return;
    }

}
