- getAttributeNames(): returns array of attribute names.
- getMajorVersion(): returns the major version number of the Java Servlet API that the remote servlet supports.
- getMinorVersion(): returns the minor version number of the Java Servlet API that the remote servlet supports.
- getMimeType(filename): returns the MIME type of the specified filename, or null if the MIME type is not known.
- getServerInfo(): returns the name and version of the servlet container on which the servlet is running.
- getServletContextName(): returns the name of this web application correponding to this ServletContext as specified in the deployment descriptor for this web application by the display-name element.
- log(msg): writes the specified message to a servlet log file, usually an event log; returns void.
- removeAttribute(name): remove attribute named name; returns void.
- setAttribute(name,value): set attribute named name with value; returns void.
