Method Details

initHttpServer

String initHttpServer(String schemeAndAuthority,
 boolean allowReuse)

Creates an HTTP server at given URI.

If there was no running HTTP server found under the passed scheme and authority, this function starts a new one. If the HTTP server supports both http and https schemes, the return value scheme will match the requested value.

Parameters:

schemeAndAuthority - the scheme and authority where to access the HTTP server. If port number is 0, then a random open port is selected and will be part of the returned URI.

allowReuse - if the port given in schemeAndAuthority is 0, setting this to true will allow returning any already running server, while false will create a new server. Has no effect if port is not 0.

Returns:

the actual assigned URI of the HTTP server.

registerContext

String registerContext(String schemeAndAuthority,
 boolean allowReuse,
 String contextPath,
 @Nullable
 String mediaType,
 @Nullable
 CommunicationLogContext communicationLogContext,
 HttpHandler handler)

Registers a handler for HTTP requests destined to the given scheme, authority and context path.

If the HTTP server supports both http and https schemes, the return value scheme will match the requested value.

Parameters:

schemeAndAuthority - scheme and authority used to start a new or re-use an existing HTTP server.

allowReuse - if the port given in schemeAndAuthority is 0, settings this to true will allow returning any already running server, while false will create a new server. Has no effect if port is not 0.

contextPath - the context path where the given registry shall listen to.
Important note: the context path needs to start with a slash.

mediaType - the media type of the response the handler will produce. Null defaults to SoapConstants.MEDIA_TYPE_SOAP.

communicationLogContext - additional information made available in the communication log of the registered context. Only has an effect if DpwsConfig.HTTP_SERVER_COMMLOG_IN_HANDLER is enabled

handler - the handler callback that is invoked on a request to the given context path.

Returns:

the actual full path of the HTTP server address the given handler listens to.

• initHttpServer(String, boolean)

unregisterContext

void unregisterContext(String schemeAndAuthority,
 String contextPath)

Removes a handler for the given scheme, authority and context path.

HttpHandler.handle(InputStream, OutputStream, CommunicationContext) will not be called for any request destined to the corresponding handler. Requests to the corresponding are answered with an HTTP 404.

Parameters:

schemeAndAuthority - scheme and authority where the context shall be removed.

contextPath - the context path to remove. The context path needs to start with a slash.
