hii,
for example
ByteArrayOutputStream bos = new ByteArrayOutputStream();
            String ret = null;
            String ret1 = null;
            String toDatum = calendarDate.getText();
            try {
                String UrlString = "http://www.someWeb";
                URL url = new URL(UrlString);
                String proxyUser = "userName";
                String proxyPassword = "pasword";
                String proxyAddress = "proxyServerDnsOrIP";
                int proxyPort = 8080;
                InetSocketAddress sa = new InetSocketAddress(proxyAddress, proxyPort);
                Proxy proxy = new Proxy(Proxy.Type.HTTP, sa);
                URLConnection conn = url.openConnection(proxy);
                //URLConnection conn = url.openConnection();
                conn.setRequestProperty("Accept-Charset", "cp1250");
                conn.setRequestProperty("Proxy-Authorization", "Basic " + new sun.misc.BASE64Encoder().encode((proxyUser + ":" + proxyPassword).getBytes()));
                InputStream in = null;
                in = conn.getInputStream();
                int len;
                byte[] buf = new byte[1024];
                while ((len = in.read(buf)) > 0) {
                    bos.write(buf, 0, len);
                String charEncoding = Charset.defaultCharset().name();
                /*String fileEncoding = System.getProperty("file.encoding");
                System.out.println("File Encoding: " + fileEncoding);
                System.out.println("Char Encoding: " + charEncoding);
                System.out.println("Char Encoding: " + Charset.availableCharsets());*/
                charEncoding = "cp1250";
                ret = new String(bos.toByteArray(), charEncoding);
                ret1 = bos.toString(charEncoding);
                groupImport = ret;
                ret1 = groupImport;
                in.close();
                proxy = null;
                conn = null;
                //removeHtmlData();
            } catch (IOException ioException) {
                ioException.printStackTrace();
                JOptionPane.showMessageDialog(null, ioException.getMessage(), "Htlm error", JOptionPane.ERROR_MESSAGE);
            }... kopik
