Java PDF Report Error

Question

I have a little java program for PDF reporting. The problem is that every time I send the PDF via Email, it opens the PDF on the screen. Where can I change, so it doesn’t open on the screen when sending by Email? follow my code:

public class Main {
   public static void main(String args[]) {
    String dirConf = args[0];

    if ((new File(dirConf)).exists())
        try {
            Map<String, String> param = (new ReadXML()).getParams(dirConf);
            server = (String) param.get("server");
            port = (String) param.get("port");
            database = (String) param.get("database");
            usuario = (String) param.get("user");
            senha = (String) param.get("password");
            url = (String) param.get("url");
            type = (String) param.get("type");
            folder = (String) param.get("folder");
            primary = (String) param.get("primary");
            secundary = (String) param.get("secundary");
            idiomas.add(primary);
            idiomas.add(secundary);
            name = getName(url);
            destFileName = (new StringBuilder(String.valueOf(folder)))
                    .append(name).append((String) param.get("id"))
                    .append(".").append(type).toString();
            sourceFileName = url;
            connection = (new ConectaProgress()).conectar(server, port,
                    database, usuario, senha);
            tempSet = param.keySet();
            Object object;
            for (Iterator<String> iterator = tempSet.iterator(); iterator
                    .hasNext(); paramJasper.put(object.toString(),
                    (String) param.get(object)))
                object = iterator.next();

            for (Iterator<String> iterator1 = idiomas.iterator(); iterator1
                    .hasNext();) {
                String string = (String) iterator1.next();
                label = (new DAO()).carregaLabel(connection, string);
                tempSet = label.keySet();
                String string1;
                for (Iterator<String> iterator2 = tempSet.iterator(); iterator2
                        .hasNext(); paramJasper.put(string1,
                        (String) label.get(string1)))
                    string1 = (String) iterator2.next();

            }

            (new Main()).exportar(type, destFileName, sourceFileName,
                    paramJasper);

        }
    else

}

Answer 1

Expensive,

At the end of the Try has the commands:

File destFile = new File(destFileName);
if (destFile.exists())
     desktop.open(destFile); <--- este principalmente.

They serve to open the file by operating system.

Looking at the export method, if you pass the pre type, it will also present the window (the JasperViewer that’s what it’s for):

if (type.equals("pre")) {
    JasperViewer jv = new JasperViewer(relatorioFinal);
    jv.setExtendedState(6);
    jv.setTitle(" RelatorioPdf");
    java.awt.image.BufferedImage imagem = ImageIO.read(getClass()
            .getClassLoader().getResource("imagem.png"));
    jv.setIconImage(imagem);
    jv.setVisible(true);

}

Answer 2

Remove from this

 if (destFile.exists())
                desktop.open(destFile);
