* It should be noted that we do NOT add {@link 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. | |
* | |
* <p> | |
* The list of serializers and parsers can be appended to using the | |
* {@link Rest#serializers() @Rest(serializers)} and | |
* {@link Rest#parsers() @Rest(parsers)} annotations on subclasses. | |
* | |
* <p> | |
* This subclass also provides a default OPTIONS page by implementing a {@link #getOptions(RestRequest)} that returns a | |
* POJO consisting of beans describing the class. | |
* | |
* <p> | |
* The OPTIONS page can be modified or augmented by overriding this method and providing your own data. | |
* | |
* <ul class='notes'> | |
* <li> | |
* Provides a default HTML stylesheet by setting {@link HtmlDocConfig#stylesheet() HtmlDocConfig(stylesheet)} | |
* to <js>"styles/juneau.css"</js>. | |
* <li> | |
* Provides a default classpath entry "htdocs" by setting | |
* {@link Rest#staticFiles() @Rest(staticFiles)} to <code>{<js>"htdocs:htdocs"</js>,<js>"styles:styles"</js>}</code>. | |
* This allows files inside the <c>[servletPackage].htdocs</c> package to be served up under the URL | |
* <c>/servletPath/htdocs</c>. | |
