Class XQueryServlet

java.lang.Object
  HttpServlet
      org.exist.http.servlets.XQueryServlet

public class XQueryServlet

extends HttpServlet

Servlet to generate HTML output from an XQuery file. The servlet responds to an URL pattern as specified in the WEB-INF/web.xml configuration file of the application. It will interpret the path with which it is called as leading to a valid XQuery file. The XQuery file is loaded, compiled and executed. Any output of the script is sent back to the client. The servlet accepts the following initialization parameters in web.xml:

user	The user identity with which the script is executed.
password	Password for the user.
uri	A valid XML:DB URI leading to the root collection used to process the request.
encoding	The character encoding used for XQuery files.
container-encoding	The character encoding used by the servlet container.
form-encoding	The character encoding used by parameters posted from HTML forms.

User identity and password may also be specified through the HTTP session attributes "user" and "password". These attributes will overwrite any other settings.
