Writing A Word Exporter for Primefaces Datatable

PDF and Excel Export are default features of primefaces datatables.
We need a doc exporter.


I saw some other posts doing this . My solution was a bit different for some restrictions(which i do not remember know :) )

Below is simple logic and necessary classes and some codes to give an idea.

Extend  org.primefaces.component.export.Exporter
Change necessary methods to add final texts to your doc generator.

import com.lowagie.text.BadElementException;

import com.lowagie.text.Document;

import com.lowagie.text.DocumentException;

import com.lowagie.text.Paragraph;

import com.lowagie.text.Table;

import com.lowagie.text.rtf.RtfWriter2;



public class DocExporter extends Exporter {



   protected Document              document;



   protected RtfWriter2            writer;



   protected Table                 doctable = null;







protected void addColumnValue(UIComponent component) throws DocumentException {

      // int cellIndex = row.getLastCellNum() == -1 ? 0 : row.getLastCellNum();

      // Cell cell = row.createCell(cellIndex);

      String value = component == null ? "" : exportValue(FacesContext.getCurrentInstance(), component);



      com.lowagie.text.Cell cell = new com.lowagie.text.Cell(value);

      cell.setBorderColor(new Color(255, 0, 0));

      // cell.setHeader(true);



      doctable.addCell(cell);



      // cell.setCellValue(new HSSFRichTextString(value));

   } 

***********************
At class extending LazyDataModel add a method as ExportDoc

public class TableModel<T> extends LazyDataModel<T> {





public void exportDoc(String reportName,boolean pageOnly) throws IOException {

      FacesContext context = FacesContext.getCurrentInstance();

      DocExporter exporter = new DocExporter();

      exporter.export(context, (DataTable) persistentUITable, reportName, pageOnly, false, "UTF-8", null, null);

      context.responseComplete();

   }
