    <p>First of all thanks to everyone that answers questions on here. I have used this forum as a java bible. This is a homework problem and here is the assignment:</p> <blockquote> <p>Write a program in Java that uses sockets to connect to a web server on port 80, requests a web page using GET of the HTTP protocol, and displays the resulting HTML</p> </blockquote> <p>Not sure if I am doing this right or not. I have a very limited understanding of java. Most of this is from tutorials I have been going through. Any website links would be greatly appreciated.</p> <p>Here is my error message:</p> <pre><code>Exception in thread "main" java.lang.Error: Unresolved compilation problems: Type mismatch: cannot convert from java.net.Socket to Socket The method getInputStream() is undefined for the type Socket </code></pre> <p>Here is my code:</p> <pre><code>import java.io.*; import java.net.*; public class Server { public static void main(String[] args) throws Exception { Server SERVER = new Server(); SERVER.run(); } public void run() throws Exception { ServerSocket one = new ServerSocket(80); //these are the two lines of code it is warning about Socket myskt = one.accept(); InputStreamReader IR = new InputStreamReader(myskt.getInputStream()); //end of warnings BufferedReader BR = new BufferedReader(IR); String message = BR.readLine(); System.out.println(message); if (message != null) { PrintStream PS = new PrintStream(System.out); PS.println("Message Received"); } URL website = new URL("www.dogs.com"); URLConnection yc = website.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader( yc.getInputStream())); String inputLine; while ((inputLine = in .readLine()) != null) System.out.println(inputLine); one.close(); } // TODO Auto-generated method stub } </code></pre>

    1. COFirst: you're asked to write a *client*, no need for server sockets then. Second, *if* you're allowed to use the `URL` class getting a page from a webserver is pretty trivial. If not I assume you're supposed to handle the whole client socket thing yourself, and write a basic http client on top of that (but a basic http client is trivial, really). So first of all get rid of the first part of your program and then make sure using URL is permitted in this assignment.

    2. COI did compete the assignment using URL and it was very easy. I think he is wanting us to use the sockets, however. So googling http client should put me on the right track?

    3. COThe error messages indicate you're having problems with variable type declarations. Get that right before worrying about the HTTP client protocol.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
