Document.add() will take forever to process a paragraph that long. Break
the text into lines, like in the following example:
public static void createPdfFromString (String aSourceString,
OutputStream aOutputStream)
throws Exception
{
try
{
Document myDocument = new
Document(PageSize.A4,5.0f,5.0f,40.0f,40.0f);
PdfWriter myPdfWriter = PdfWriter.getInstance(myDocument,
aOutputStream);
myDocument.open();
String s;
BufferedReader rr = new BufferedReader(new
StringReader(aSourceString));
Font font = new Font(Font.COURIER,10);
while ((s = rr.readLine()) != null) {
if (s.length() == 0) {
s = "\n";
}
Paragraph para = new Paragraph(12,s,font);
myDocument.add(para);
}
myDocument.close();
}
catch (Exception myException)
{
throw myException;
}
}
