how to solve java.io.IOException

[vikassawant]

hi,
I am trying to import excel file in JTable.For that I used following code,

import com.zfqjava.swi ng.*;
import org.apache.poi. hssf.usermodel. *;
import org.apache.poi. hssf.usermodel. HSSFSheet;
import org.apache.poi. hssf.usermodel. HSSFWorkbook;
import org.apache.poi. poifs.filesyste m.POIFSFileSyst em;


FileDialog fd=new FileDialog(new Frame());

fd.setMode(File Dialog.LOAD);
fd.setTitle("Op en");
fd.show();
String nm=fd.getFile() ;
System.out.prin tln(nm);

try{

POIFSFileSystem fs=new POIFSFileSystem (new FileInputStream (nm));
HSSFWorkbook wb=new HSSFWorkbook(fs );
FileOutputStrea m fileOut = new FileOutputStrea m(nm);
wb.write(fileOu t);
fileOut.close() ;
System.out.prin tln("Your excel file has been generated");

} catch ( Exception ex )
{
System.out.prin tln(ex);
}



Error is-

java.io.IOExcep tion : Invalid header signature;read 795465215648951 542, expectd -222498542445424 15674896

what is wrong here?

Thanks in advance.

Are you trying to read an Excel MS Office 2007 file? Try to write the file as an earlier version.

kind regards,
