I want to generate PDFs from JSP view pages. Searching on web related topics I got this mail ID from Manning Publishers site.
I have to use only tidy and iText only
Please give me a help, it is very urgent.
I what I am doing is,
Step 1:
I have no of jsps. I am putting pdf icon on each page and onclick I am calling JavaScript and then Servlet class.
In the Servlet class I am able to get the JSP output(content) as HTML content and making it as String.
String htmlFile = request.getParameter("html_input");//html_input will have the content
Step 2:
Creating ByteArray Streams and passing html string to input stream.
ByteArrayInputStream is = new ByteArrayInputStream(htmlFile.getBytes());
ByteArrayOutputStream os = new ByteArrayOutputStream();
Step 3
Creating iText Document
Document document = new Document();
Step 4
Using tidy, I am doing cleanning the html file
Tidy tidy = new Tidy();
tidy.setTidyMark(false);
tidy.setDocType("auto");
tidy.setWrapScriptlets(true);
tidy.setOnlyErrors(true);
tidy.setXHTML(true);
tidy.setEncloseText(true);
tidy.setXmlTags
(true);
Step 5
Parsing the file to DOM and creating new string on output steam
tidy.parseDOM(is, os); // Here parsing is perfect, but I am not getting "os" content. os is empty
String newString = os.toString();
// Here since os is empty newString is empty ie no string.IS THERE ANY MECHINSM TO DO THIS. IN THE TIDY PARSE I AM GETTING DOM-DOCUMENT THAT HAS TO BE CONVERT AS STRING
I TRIED TO USE SAX-PARSER ALSO BUT THAT GOING TO COMPLEX. I WANT TO PUT SIMPLE TECHNIC
Step 6
Creating itext Document instance
PdfWriter.getInstance(document, response.getOutputStream());
Step 7
I am opening the Document
document.open();
Step 8
Adding the string to Paragraph
document.add(new Paragraph (newString));// Here I am able to see this paragraph on PDF page
document.add(new Paragraph ("This is test page")); // This is perfect
Step 9
Closing stmts
document.close();
os.close();
