不使用iText将内容导出为pdf

Question

I have worked on exporting the html(table)contents to excel using table id. I have used content type like

 response.getWriter().write(datatoexport);
 response.setHeader("Content-Type", "application/vnd.ms-excel");
 response.setHeader("Content-Disposition", "attachment; filename=test_file.xls");
 response.getWriter().flush();
 response.getWriter().close();

Here, datatoexport is the table id.

It is working fine with excel.

But, if I use content type as pdf like

 response.setHeader("Content-Type", "application/pdf");
 response.setHeader("Content-Disposition", "attachment; filename=test_file.pdf");

But, I am getting pdf file is corrupted. Any help? Without using iText or other jars, How can I achieve it? Especially in IE 8

Answer 1

Before sending pdf file to output, you need to generate it on the server side.

To convert your file to PDF I recommend to use OpenOffice in headless mode and JODConverter .

To run OpenOffice in headless mode (in Windows) run the command (assume you have OpenOfficePortable, installed in C:\\Apps :

"C:\Apps\OpenOfficePortable\OpenOfficePortable.exe" -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

As you have OpenOffice started in headless mode, run a simple working prototype using JODConverter library:

import com.artofsolving.jodconverter.DocumentConverter;
import com.artofsolving.jodconverter.openoffice.connection.OpenOfficeConnection;
import com.artofsolving.jodconverter.openoffice.connection.SocketOpenOfficeConnection;
import com.artofsolving.jodconverter.openoffice.converter.OpenOfficeDocumentConverter;
import java.io.File;
import java.net.ConnectException;

public class JODConv {  
    public static void main(String[] args) throws ConnectException {

        if (args.length!=2) {
            System.out.println("Usage:\nJODConv <file-to-convert> <pdf-file>");
            System.exit(0);
        }

        String sourceFilePath = args[0];
        String destFilePath = args[1];


        File inputFile = new File(sourceFilePath);
        File outputFile = new File(destFilePath);

        // connect to an OpenOffice.org instance running on port 8100
        OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
        connection.connect();

        // convert
        DocumentConverter converter = new OpenOfficeDocumentConverter(connection);
        converter.convert(inputFile, outputFile);

        // close the connection
        connection.disconnect();
    }       
}
