When the user is presented with the "File Download" dialog box from Adobe,
they have the choice of "Open", "Save", or "Cancel".
Open and Save work fine, but when I click "Cancel", I get a SocketException.
I am using J2EE with Struts. The PDF file is generated via creating a
Document and writing to the Java Graphics2D. Here's the routine which
builds the PDF:
public void createPrintPreviewPDF( javax.servlet.http.HttpSession session)
{ Document document = null;
PdfWriter writer = null;
PdfContentByte cb = null;
try
{ // Specify Document size with no margins
document = new Document( super.LETTER_SIZE, 0, 0, 0, 0 );
String docRoot = session.getServletContext().getRealPath("/");
writer = PdfWriter.getInstance(document, new
java.io.FileOutputStream( docRoot + "contract.pdf") );
document.open();
cb = writer.getDirectContent();
g = cb.createGraphics( super.LETTER_WIDTH, super.LETTER_HEIGHT);
}
catch(DocumentException de) { System.out.println("Document
problem: " + de.getMessage()); }
catch(Exception e) { System.out.println("Problem: " +
e.getMessage()); }
// This creates 8 pages of the same form
for ( int i=0; i < 8; i++ )
{ cb.saveState();
printContract(); // This writes to Graphics2D
cb.restoreState();
try { document.newPage(); }
catch(DocumentException dex)
{ System.out.println("Document New Page problem: " +
dex.getMessage());
break;
}
}
document.close(); // Send the PDF to the user
writer.close();
} // end createPrintPreviewPDF()
Here's the Stack trace:
