XMLWriter problem : Bug?

Hello,
          I am trying to use the XMLwriter to write an SOAP like message. Here 
is the code:

                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                XmlWriter writer=new XmlWriter(new OutputStreamWriter(baos));
                
                String PG_Data_enc = base64_enc_dec.encode(PG_Data);
                try{
                        writer.startTag("SOAP-ENV:Envelope "+
                                
"xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"; " +
                                "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"; 
" +
                                
"xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\"; "+
                                
"xmlns:SOAP-ENV=\"http://schemas/xmlsoap.org/soap/envelope/\"; ");
                               
                        writer.startTag("SOAP-ENV:Body");
                        
writer.startTag("SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\"";);
                        writer.startTag("Name xmlns=\"\" 
xsi:type=\"xsd:string\"");
                        writer.write(Name);
                        writer.endTag();
                        writer.startTag("SerialID xmlns=\"\" 
xsi:type=\"xsd:long\"");
                        writer.write(Long.toString(serialID));
                        writer.endTag();
                        writer.startTag("R_SerialID xmlns=\"\" 
xsi:type=\"xsd:long\"");
                        writer.write(Long.toString(R_serialID));
                        writer.endTag();
                        writer.startTag("Pg_Data xmlns=\"\" 
xsi:type=\"xsd:string\"");
                        writer.write(PG_Data_enc);
                        writer.endTag();
                        writer.endTag();
                        writer.endTag();
                        writer.endTag();
                        
                    String dataString= baos.toString();
                    byte[] data = baos.toByteArray();
                    
                    System.out.println("XML Data:" + dataString);
                    System.out.println("XML Data:" + data);     

When I try to print the "dataString" and "data" I get no output. Am I doing 
something wrong? Please help me out. Is this a bug?
