Appending a "\n" to a file created.

Question

I am reading database column values and writing it to a file.
I want to add a "\n" after each line is read,but even if I
append a "\n" to the file,the file output comes all on
the same line.
How do I add the "\n" to the values read so that the output looks like
RDB,234567,4567
LON,345677,8970
EUR,456880,9833This is my code :
try {
           FileWriter fWrite  = new FileWriter("/JavaWorks/OS1.txt",true);
           for ( int i = 0; i < rowCount; i++ ) {
               Object entity =  stm_OS.getValueAt(i, stm_OS.getColumnIndex("id_entity"));
               Object ca     =  stm_OS.getValueAt(i, stm_OS.getColumnIndex("id_ca"));
               Object inst   =  stm_OS.getValueAt(i, stm_OS.getColumnIndex("id_inst"));
             String source = entity .toString()+ ","  +
                             ca.toString()     + ","  +
                             inst.toString()   + ","  + "\n";  // putting "\n" here doesnt help.
              char buffer[] = new char[source.length()];
              source.getChars(0,source.length(),buffer,0);
              for(int b=0; b<buffer.length; b++){
                fWrite.write(buffer);
}catch(Exception e){}

Hi,
No luck with using PrintWriter to append a "\n"..
Any suggestions?
try {
       FileWriter fWrite2  = new FileWriter("/JavaWorks/OS2.txt",true);
       PrintWriter pWriter = new PrintWriter(fWrite2);
           for ( int i = 0; i < rowCount; i++ ) {
               Object entity =  stm_OS.getValueAt(i, stm_OS.getColumnIndex("id_entity"));
              Object ca     =  stm_OS.getValueAt(i, stm_OS.getColumnIndex("id_ca"));
              Object inst   =  stm_OS.getValueAt(i, stm_OS.getColumnIndex("id_inst"));
           String source = entity .toString()+ ","  +
                           ca.toString()     + ","  +
                       inst.toString()   + ","  ;
                 char buffer[] = new char[source.length()];
           source.getChars(0,source.length(),buffer,0);
              for(int b=0; b<buffer.length; b++){
                     pWriter.write(buffer);
               pWriter.write("\n");
}catch(Exception e){}
