public abstract class BasicRestServlet
extends RestServlet
implements BasicRestConfig

Subclass of RestServlet with default serializers and parsers defined.

Supports the following request Accept header values with the resulting response Content-Type:

Accept	Content-Type	Serializer
application/json text/json	application/json	JsonSerializer
application/json+simple text/json+simple	application/json	SimpleJsonSerializer
application/json+schema text/json+schema	application/json	JsonSchemaSerializer
text/xml	text/xml	XmlDocSerializer
text/xml+schema	text/xml	XmlSchemaDocSerializer
text/html	text/html	HtmlDocSerializer
text/html+stripped	text/html	HtmlStrippedDocSerializer
text/uon	text/uon	UonSerializer
application/x-www-form-urlencoded	application/x-www-form-urlencoded	UrlEncodingSerializer
text/xml+soap	text/xml	SoapXmlSerializer
text/plain	text/plain	PlainTextSerializer

Supports the following request Content-Type header values:

Content-Type	Parser
application/json text/json	JsonParser
text/xml application/xml	XmlParser
text/html text/html+stripped	HtmlParser
text/uon	UonParser
application/x-www-form-urlencoded	UrlEncodingParser
text/plain	PlainTextParser

It should be noted that we do NOT add JsoParser to the list of parsers since this could cause security issues. Use caution when using this particular parser as it could inadvertently cause code execution security holes.

The list of serializers and parsers can be appended to using the @Rest(serializers) and @Rest(parsers) annotations on subclasses.

This subclass also provides a default OPTIONS page by implementing a getOptions(RestRequest) that returns a POJO consisting of beans describing the class.

The OPTIONS page can be modified or augmented by overriding this method and providing your own data.

• Provides a default HTML stylesheet by setting HtmlDocConfig(stylesheet) to "styles/juneau.css".
• Provides a default classpath entry "htdocs" by setting @Rest(staticFiles) to {"htdocs:htdocs","styles:styles"}. This allows files inside the [servletPackage].htdocs package to be served up under the URL /servletPath/htdocs.
