Well i'm stucked with a problem,
I need to create a PDF with a html source and i did this way:
File pdf = new File("/home/wrk/relatorio.pdf");
OutputStream out = new FileOutputStream(pdf);
InputStream input = new ByteArrayInputStream(build.toString().getBytes());//Build is a StringBuilder obj
Tidy tidy = new Tidy();
Document doc = tidy.parseDOM(input, null);
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(doc, null);
renderer.layout();
renderer.createPDF(out);
out.flush();
out.close();
well i'm using JSP so i need to download this file to the user not write in the server...
How do I transform this Outputstream output to a file in the java without write this file in hard drive ?
If you're using VRaptor 3.3.0+ you can use the ByteArrayDownload
class. Starting with your code, you can use this:
@Path("/download-relatorio")
public Download download() {
// Everything will be stored into this OutputStream
ByteArrayOutputStream out = new ByteArrayOutputStream();
InputStream input = new ByteArrayInputStream(build.toString().getBytes());
Tidy tidy = new Tidy();
Document doc = tidy.parseDOM(input, null);
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(doc, null);
renderer.layout();
renderer.createPDF(out);
out.flush();
out.close();
// Now that you have finished, return a new ByteArrayDownload()
// The 2nd and 3rd parameters are the Content-Type and File Name
// (which will be shown to the end-user)
return new ByteArrayDownload(out.toByteArray(), "application/pdf", "Relatorio.pdf");
}
