Method Details

createHttpServer

public abstract HttpServer createHttpServer(InetSocketAddress addr, int backlog) throws IOException
creates a HttpServer from this provider
Parameters:
addr - the address to bind to. May be null
backlog - the socket backlog. A value of zero means the systems default
Returns:
An instance of HttpServer
Throws:
IOException - if an I/O error occurs

createHttpsServer

public abstract HttpsServer createHttpsServer(InetSocketAddress addr, int backlog) throws IOException
creates a HttpsServer from this provider
Parameters:
addr - the address to bind to. May be null
backlog - the socket backlog. A value of zero means the systems default
Returns:
An instance of HttpServer
Throws:
IOException - if an I/O error occurs

provider

public static HttpServerProvider provider()
Returns the system wide default HttpServerProvider for this invocation of the Java virtual machine.

The first invocation of this method locates the default provider object as follows:

  1. If the system property com.sun.net.httpserver.HttpServerProvider is defined then it is taken to be the fully-qualified name of a concrete provider class. The class is loaded and instantiated; if this process fails then an unspecified unchecked error or exception is thrown.

  2. If a provider class has been installed in a jar file that is visible to the system class loader, and that jar file contains a provider-configuration file named com.sun.net.httpserver.HttpServerProvider in the resource directory META-INF/services, then the first class name specified in that file is taken. The class is loaded and instantiated; if this process fails then an unspecified unchecked error or exception is thrown.

  3. Finally, if no provider has been specified by any of the above means then the system-default provider class is instantiated and the result is returned.

Subsequent invocations of this method return the provider that was returned by the first invocation.

Returns:
The system-wide default HttpServerProvider
