Examples with Socket java.net.Socket used on opensource projects

Example 1 with Socket

use of java.net.Socket in project camel by apache.

the class MinaTcpLineDelimiterUsingPlainSocketTest method sendAndReceive.

private String sendAndReceive(String input) throws IOException {
    byte[] buf = new byte[128];
    Socket soc = new Socket();
    soc.connect(new InetSocketAddress("localhost", getPort()));
    // Send message using plain Socket to test if this works
    OutputStream os = null;
    InputStream is = null;
    try {
        os = soc.getOutputStream();
        // must append MAC newline at the end to flag end of textline to Camel-Mina
        os.write((input + "\r").getBytes());
        is = soc.getInputStream();
        int len = is.read(buf);
        if (len == -1) {
            // no data received
            return null;
        }
    } finally {
        IOHelper.close(is, os);
        soc.close();
    }
    // convert the buffer to chars
    StringBuilder sb = new StringBuilder();
    for (byte b : buf) {
        char ch = (char) b;
        if (ch == '\r' || ch == 0) {
            // use MAC delimiter denotes end of text (added in the end in the processor below)
            break;
        } else {
            sb.append(ch);
