Creating new word doc with POI

Hi,

Im working on creating new doc using POI. i found a sample code:

import java.util.*;
import java.io.*;
import java.lang.*;
import org.apache.poi.hwpf.*;
import org.apache.poi.hwpf.usermodel.*;
import org.apache.poi.poifs.filesystem.*;
 
public class test4 {
     
     private static String _blankFile = "blank.doc";
     
     
     private static void copyBlankHWPF (String name) {
          
          try {
               HWPFDocument doc = new HWPFDocument(new
FileInputStream(_blankFile));
               OutputStream out = new FileOutputStream(name);
               doc.write(out);
          } catch (Exception ex) {
               ex.printStackTrace();
          }
     }
     
     public static void main(String [] args){
          String generatedFile =
args[1].substring(0,args[1].length()-3)+"-generated.doc";
          try {
               copyBlankHWPF(generatedFile);
               HWPFDocument templateFile = new HWPFDocument(new
FileInputStream(args[0]));
               HWPFDocument blankFile = new HWPFDocument(new
FileInputStream(_blankFile));
               OutputStream out = new FileOutputStream(generatedFile);
               Range blankRange = blankFile.getRange();
               Range  templateRange= templateFile.getRange();
               String templateContent = templateRange.text();
               templateContent =
templateContent.replaceAll(string1,string2);
               blankRange.insertBefore(templateContent);
               blankFile.write(out);
          } catch (Exception ex) {
               ex.printStackTrace();
          }
     }
}


when i run the code it will throw an exception:

java.io.FileNotFoundException: blank.doc 



i created a blank.doc in my current directory but i got this error when i
run again the application:

Error getting property set with name ♣DocumentSummaryInformation
java.io.FileNotFoundException: no such entry: "♣DocumentSummaryInformation"
Error getting property set with name ♣SummaryInformation
java.io.FileNotFoundException: no such entry: "♣SummaryInformation"
Error getting property set with name ♣DocumentSummaryInformation
java.io.FileNotFoundException: no such entry: "♣DocumentSummaryInformation"
Error getting property set with name ♣SummaryInformation
java.io.FileNotFoundException: no such entry: "♣SummaryInformation"



i dont know what happen here, i found a site:
http://java.sys-con.com/read/45846.htm that state: The POI distribution
comes with one called "blank.doc."

But i coudn't found it in distribution folder.

Does anyone know how to make this code running? I am new to all of this.

Thanks in advance.

Hi Mohit,

you should use an empty Word file as a "template" for POI. Creating a
Word file from scratch is not supported. When you open an empty Word
file, fill it with the content and save it using a different filename,
it is probably the easiest solution.

Best wishes, Rainer

Hello,

I'm also very new to POI . I'm also not getting able to create a word doc.
I got able to read the existing file and I can copy the content of old file
to new one.
But i want to create a word doc and want to write my content what i'm
getting from console.

Please can you help me?

Thanks.

HWPFDocument is a subclass of POIDocument. That has readProperties() and
writeProperties(...). readProperties() is called already, but upon a write
the writeProperties is missing. To fix it add a line at the end of the
function HWPFDocument.write(...) as shown below:

  public void write(OutputStream out) throws IOException
  {
    ...
    // spit out the Word document.
    POIFSFileSystem pfs = new POIFSFileSystem();
    pfs.createDocument(new ByteArrayInputStream(mainBuf), "WordDocument");
    pfs.createDocument(new ByteArrayInputStream(tableBuf), "1Table");
    pfs.createDocument(new ByteArrayInputStream(dataBuf), "Data");
    // write the properties:
    writeProperties(pfs);       // <-- insert this
    pfs.writeFilesystem(out);
  }

That should do it.

Best wishes,
Rainer

The property sets DocumentSummaryInformation and SummaryInformation do
not belong to the Word document as such. You have to create them using
POI's HPSF component, see <http://jakarta.apache.org/poi/hpsf/> for
details. I don't know whether HWPF has any functionalities to
encapsulate the HPSF stuff for you.
