Hi,
i want to print a pdf file silently via java code but the following
exception is thrown by document.close(): ExceptionConverter:
java.io.IOException: The document has no pages.
Opening the document is successful and the document also has a content.
I use itext-2.0.4.jar.
Here is my java code:
...
com.lowagie.text.Document document = new com.lowagie.text.Document();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
baos.write(bytes); //bytes contains the document content
try {
PdfWriter writer = PdfWriter.getInstance(document, baos);
document.open();
writer.addJavaScript("this.print(false);", false); //for silently
printing
document.close();
} catch (Exception e) {
e.printStackTrace();
}
final FacesContext context = FacesContext.getCurrentInstance();
final HttpServletResponse response = (HttpServletResponse)
context.getExternalContext().getResponse();
response.setContentType("application/pdf");
response.setContentLength(bytes.length);
response.setHeader("Content-disposition", "attachment; filename=test.pdf");
response.getOutputStream().write(bytes);
response.getOutputStream().flush();
final StateManager stateManager =
context.getApplication().getStateManager();
stateManager.saveSerializedView(context);
// Finalize task.
context.responseComplete();
...
Thanks for helpful responses in advance,
Tom
