OpenOffice convert doc to pdf with JAVA

Question

I know its have multiple question about it. But I've already read tons of it and it still doesnt work. I have installed OpenOffice to my comp : https://www.openoffice.org/download/index.html

I have also tried this solution, doesnt work : connection failed while connecting to OpenOffice .org

If I want to run my code i get the following error:

    Exception in thread "main" java.net.ConnectException: connection failed: socket,host=localhost,port=8100,tcpNoDelay=1: java.net.ConnectException: Connection refused: connect
        at com.artofsolving.jodconverter.openoffice.connection.AbstractOpenOfficeConnection.connect(AbstractOpenOfficeConnection.java:79)
        at TestCon.main(TestCon.java:24

)

How can I mange to Connect to my openoffice program. PS: I want to use it on windows 7 64x

I use this simple code

import java.io.File;
import java.net.ConnectException;

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;


public class TestCon {

    /**
     * @param args
     * @throws ConnectException 
     */
    public static void main(String[] args) throws ConnectException {
        // TODO Auto-generated method stub
        File inputFile = new File("Resume.doc");
        File outputFile = new File("document.pdf");

        // 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();
    }
}

You have to start the openoffice service:

 soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

Then you can connect to this service and convert you document.
