The following helper method opens a new spreadsheet document component. The method getRemoteServiceManager() retrieves a connection. Refer to chapter First Steps for additional information.

  import com.sun.star.lang.XComponent;
  import com.sun.star.frame.XComponentLoader;
  import com.sun.star.beans.PropertyValue;
  protected XComponent newSpreadsheetComponent() throws java.lang.Exception {
      String loadUrl = "private:factory/scalc";
      xRemoteServiceManager = this.getRemoteServiceManager(unoUrl);
      Object desktop = xRemoteServiceManager.createInstanceWithContext(
          "com.sun.star.frame.Desktop", xRemoteContext);
      XComponentLoader xComponentLoader = (XComponentLoader)UnoRuntime.queryInterface(
          XComponentLoader.class, desktop);
      PropertyValue[] loadProps = new PropertyValue[0];
      return xComponentLoader.loadComponentFromURL(loadUrl, "_blank", 0, loadProps); 

Our helper returns a com.sun.star.lang.XComponent interface for the recently loaded document. Now the XComponent is passed to the following method insertSpreadsheet() to add a new spreadsheet to our document.

  import com.sun.star.sheet.XSpreadsheetDocument;
  import com.sun.star.sheet.XSpreadsheet; 
  /** Inserts a new empty spreadsheet with the specified name.
      @param xSheetComponent The XComponent interface of a loaded document object
      @param aName The name of the new sheet.
      @param nIndex The insertion index.
      @return The XSpreadsheet interface of the new sheet.
  public XSpreadsheet insertSpreadsheet(XComponent xSheetComponent, String aName, short nIndex) {
      XSpreadsheetDocument xDocument = (XSpreadsheetDocument)UnoRuntime.queryInterface(
          XSpreadsheetDocument.class, xSheetComponent);
      // Collection of sheets
      com.sun.star.sheet.XSpreadsheets xSheets = xDocument.getSheets();
      com.sun.star.sheet.XSpreadsheet xSheet = null;
      try {
          xSheets.insertNewByName(aName, nIndex);
          xSheet = (com.sun.star.sheet.XSpreadsheet) UnoRuntime.queryInterface(
              com.sun.star.sheet.XSpreadsheet.class, xSheets.getByName(aName));
      } catch (Exception ex) {
      return xSheet;
