Try this to generate a Word file.....
import com.jacob.activeX.*;
import com.jacob.com.*;
public class ExportDOC {
public ExportDOC () {
//Application type
ActiveXComponent doc = new ActiveXComponent("Word.Application");
//Application visible
doc.setProperty("Visible", new Variant(true));
Object documents = doc.getProperty("Documents").toDispatch();
//Open a file already exits
//Object document = Dispatch.call(documents, "Open", "c:/nameFile.doc").toDispatch();
//Open a new file empty
Object document = Dispatch.call(documents, "Add", "").toDispatch();
Object selection = Dispatch.get(doc,"Selection").toDispatch();
//Text Format
Object font = Dispatch.get(selection, "Font").toDispatch();
Object alignment = Dispatch.get(selection, "ParagraphFormat").toDispatch();
Object image = Dispatch.get(selection, "InLineShapes").toDispatch();
//I put the selection at the end of the file for if I want to add text
//Dispatch.call(selection, "EndKey", "6");
//Text format (bold & italic)
Dispatch.put(font, "Bold", "1");
Dispatch.put(font, "Italic", "1");
//To jump line
Dispatch.call(selection, "TypeParagraph");
//Align center (0= left, 1=center, 2=right, 3=justify)
Dispatch.put(alignment, "Alignment", "1");
//Insert image
Dispatch.call(image, "AddPicture", "c:/graf.jpg");
Dispatch.call(selection, "TypeParagraph");
Dispatch.put(alignment, "Alignment", "3");
//Insert Text
Dispatch.call(selection, "TypeText", "Text ....... ");
//Original values
Dispatch.call(selection, "TypeParagraph");
Dispatch.put(alignment, "Alignment", "0");
Dispatch.put(font, "Bold", "0");
Dispatch.put(font, "Italic", "0");
//To jump page
//Dispatch.call(select, "InsertBreak");
//Save the document
//Dispatch.call(document, "SaveAs", "c:/test.doc");
//Quit the application
//dc.invoke("Quit", new Variant[] {});
public static void main(String[] args) {
ExportDOC e = new ExportDOC();
but you must download 'jacob.jar' in....
