org.gvsig.fmap.dal.store.dbf.utils.DbaseFileWriter

public class DbaseFileWriter
extends Object

A DbaseFileReader is used to read a dbase III format file. The general use of this class is:

 DbaseFileHeader header = ...
 WritableFileChannel out = new FileOutputStream("thefile.dbf").getChannel();
 DbaseFileWriter w = new DbaseFileWriter(header,out);
 while ( moreRecords ) {
   w.write( getMyRecord() );
 }
 w.close();
 

You must supply the moreRecords and getMyRecord() logic...
