Utilizing Socket utilities to handle TCP and HTTP socket connections

The ETL Development API provides various methods to handle socket connections that are present in the following class:

  • (com.neptuny.cpit.etl.util.SocketUtil)

You can connect to a remote host that supports TCP and UDP connections using the following method:

  • connect(protocol, host, port)

Once the connection is established, the following methods can be used to send and receive data through the socket:

  • send(message)
  • receive(max_row) (the max_row parameter is optional)

The following code examples illustrate the usage of methods discussed so far in this section:


SocketUtil s = new SocketUtil();
# set the connection timeout
s.setTimeout(200);
# connect to server
s.connect("tcp","HOST","PORT");
# receive 4 lines from socket
ArrayList<String> retline = s.receive(4);
s.send("a message");
s.close();
