I have a home-work to create a http server with java , a simple one and from scratch . After searching google and here ...i found this link "see the best response" with a very nice response ,so i copy/paste this example to eclipse , but it doesn't recognize the package
import com.sun.net.httpserver.Headers;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
can you please help me so i can make eclipse recognize them? Also if isn't asking for to much do you know some other link with a HttpServer example? Thank you in advance !

It should be available with JDK from 1.6 onwards. Otherwise, you can add it your buidpath separately. Refer below link:

I had the same problem with Java 8.
com.sun.net.httpserver is not API (there is an access restriction, and Eclipse indicate this as error).
You need to add an access rule "Accessible" for the pattern com/sun/net/httpserver/**:

I hit same Issue on Mac OSX 10.8, Eclipse Kepler Service Release 2. I found that it is depends what JVM you use. Changing JVM from Apple(Default) to Oracle resolved the issue.

By any chance, are you using Java 5.0? Unfortunately, the jar doesn't come bundled with a Java 5.0 SDK and you would want to download the httpserver jar from this location and set it in your classpath.

The simplest solution for this is to go to build path configuration and change the JRE from the default MAC. Simply remove the one presented and add the one from your java installation path, for example:
Library/Java/JavaCirtualMachines/jdk.1.8.0_191.jdk/Contents/Home/bin
When addding new JREs choose Standard VM instead of MacOS X VM
