hi
thanks for the reply,
that works only if .png file is there in the path.
i worked it out, it is working fine now
try
               httpConn = (HttpConnection)Connector.open(url);
               is=httpConn.openInputStream();
               responseCode = httpConn.getResponseCode();
               if(httpConn.getResponseCode() == 200)
                         ByteArrayOutputStream bStrm = null;
                         byte[] data = new byte[512];
                         int contentLen = httpConn.getHeaderFieldInt("Content-Length", 0);
                         if(contentLen > 0)
                              response = new byte[contentLen];
                         else
                              bStrm = new ByteArrayOutputStream();
                         int count = 0, tmp =0;
                              while ((count = is.read(data)) >= 0)
                                   if( contentLen > 0 )
                                        for(int i=0;i<count && tmp+i < contentLen;i++)

                              System.gc();
