/**
* Example program from Chapter 1 Programming Spiders, Bots and Aggregators in
* Java Copyright 2001 by Jeff Heaton
*
* SendMail is an example of client sockets. This program presents a simple
* dialog box that prompts the user for information about how to send a mail.
*

/*
* Using the SMTP Program
*
* To use the program in Listing 1.2, you must know the address of an SMTP
* server usually provided by your ISP. If you are unsure of your SMTP server,
* you should contact your ISP"s customer service. In order for outbound e-mail
* messages to be sent, your e-mail program must have this address. Once it
* does, you can enter who is sending the e-mail (if you are sending it, you
* would type your e-mail address in) and who will be on the receiving end. This
* is usually entered under the Reply To field of your e-mail program. Both of
* these addresses must be valid. If they are invalid, the e-mail may not be
* sent. After you have entered these addresses, you should continue by entering
* the subject, writing the actual message, and then clicking send. Note
*
* For more information on how to compile examples in this book, see Appendix E
* "How to Compile Examples Under Windows."
*
* As stated earlier, to send an e-mail with this program, you must enter who is
* sending the message. You may be thinking that you could enter any e-mail
* address you want here, right? Yes, this is true; as long as the SMTP server
* allows it, this program will allow you to impersonate anyone you enter into
* the To address field. However, as previously stated, a savvy Internet user
* can tell whether the e-mail address is fake.
*
* After the mention of possible misrepresentation of identity on the sender"s
* end, you may now be asking yourself, Is this program dangerous? This
* program is no more dangerous than any e-mail client (such as Microsoft
* Outlook Express or Eudora) that also requires you to tell it who you are. In
* general, all e-mail programs must request both your identity and that of the
* SMTP server. Examining the SMTP Server
*
* You will now be shown how this program works. We will begin by looking at how
* a client socket is created. When the client socket is first instantiated, you
* must specify two parameters. First, you must specify the host to connect to;
* second, you must specify the port number (e.g., 80) you would like to connect
* on. These two items are generally passed into the constructor. The following
* line of code (from Listing 1.2) accomplishes this:
*
* java.net.Socket s =new java.net.Socket( _smtp.getText(),25 );
*
* This line of code creates a new socket, named s. The first parameter to the
* constructor, _smtp .getText(), specifies the address to connect to. Here it
* is being read directly from a text field. The second parameter specifies the
* port to connect to. (The port for SMTP is 25.) Table 1.1 shows a listing of
* the ports associated with most Internet services. The hostname is retrieved
* from the _smtp class level variable, which is the JTextField control that the
* SMTP hostname is entered into.
*
* If any errors occur while you are making the connection to the specified
* host, the Socket constructor will throw an IOException. Once this connection
* is made, input and output streams are obtained from the Socket.getInputStream
* and Socket.getOutputStream methods. This is done with the following lines of
* code from Listing 1.2:
*
* _out = new java.io.PrintWriter(s.getOutputStream());
* _in = new java.io.BufferedReader(new java.io.InputStreamReader(s.getInputStream()));
*
* These low-level stream types are only capable of reading binary data. Because
* this data is needed in text format, filters are used to wrap the lower-level
* input and output streams obtained from the socket.
*
* In the code above, the output stream has been wrapped in a PrintWriter
* object. This is because PrintWriter allows the program to output text to the
* socket in a similar manner to the way an application would write data to the
* System.out object by using the print and println methods. The application
* presented here uses the println method to send commands to the SMTP server.
* As you can see in the code, the InputStream object has also been wrapped; in
* this case, it has been wrapped in a BufferedReader. Before this could happen,
* however, this object must first have been wrapped in an InputStreamReader
* object as shown here:
*
* _in = new java.io.BufferedReader(new
* java.io.InputStreamReader(s.getInputStream()));
*
* This is done because the BufferedReader object provides reads that are made
* up of lines of text instead of individual bytes. This way, the program can
* read text up to a carriage return without having to parse the individual
* characters. This is done with the readLine method.
*
* You will now be shown how each command is sent to the SMTP server. Each of
* these commands that is sent results in a response being issued from the SMTP
* server. For the protocol to work correctly, each response must be read by the
* SMTP client program. These responses start with a number and then they give a
* textual description of what the result was. A full-featured SMTP client
* should examine these codes and ensure that no error has occurred.
*
* For the purposes of the SendMail example, we will simple ignore these
* responses because most are informational and not needed. Instead, for our
* purposes, the response will be read in and displayed to the _output list box.
* Commands that have been sent to the server are displayed in this list with a
* C: prefix to indicate that they are from the client. Responses returned from
* the SMTP server will be displayed with the S: prefix.
*
* To accomplish this, the example program will use the send method. The send
* method accepts a single String parameter to indicate the SMTP command to be
* issued. Once this command is sent, the send method awaits a response from the
* SMTP host. The portion of Listing 1.2 that contains the send method is
* displayed here:
*
* protected void send(String s) throws java.io.IOException {
// Send the SMTP command
if(s!=null) {
_model.addElement("C:"+s);
_out.println(s);
_out.flush(); }
// Wait for the response
String line = _in.readLine();
if(line!=null) {
_model.addElement("S:"+line);
}
}
*
* As you can see, the send method does not handle the exceptions that might
* occur from its commands. Instead, they are thrown to the calling method as
* indicated by the throws clause of the function declaration. The variable s is
* checked to see if it is null. If s is null, then no command is to be sent and
* only a response is sought. If s is not null, then the value of s is logged
* and then sent to the socket. After this happens, the flush command is given
* to the socket to ensure that the command was actually sent and not just
* buffered. Once the command is sent, the readLine method is called to await
* the response from the server. If a response is sent, then it is logged.
*
* Once the socket is created and the input and output objects are created, the
* SMTP session can begin. The following commands manage the entire SMTP
* session:
*
* send(null);
* send("HELO " + java.net.InetAddress.getLocalHost().getHostName() );
* send("MAIL FROM: " + _from.getText() ); send("RCPT TO: " + _to.getText() );
* send("DATA");
* _out.println("Subject:" + _subject.getText()); _out.println(
* _body.getText() ); send("."); s.close();
*
* Tip
*
* Refer to Table 1.4 in the preceding section to review the details of what
* each of the SMTP commands actually means.
*
* The rest of the SendMail program (as seen in Listing 1.2) is a typical Swing
* application. The graphical user interface (GUI) layout for this application
* was created using VisualCaf?. The VisualCaf? comments have been left in to
* allow the form"s GUI layout to be edited by VisualCaf? if you are using it.
* If you are using an environment other than VisualCaf?, you may safely delete
* the VisualCaf? comments (lines starting in //). The VisualCaf? code only
* consists of comments and does not need to be deleted to run on other
* platforms.
