* [[RESTXQ]] allows you to write web applications with XQuery,* [[REST]] offers a RESTful API for accessing database resources via URLs, and* [[WebDAV]] provides access to databases via the file system.=Startup=
This article describes different ways * Run one of deploying and configuring these servicesthe {{Code|basexhttp}} or {{Code|basexhttp.bat}} scripts. Call the script with the {{Code|stop}} keyword to gracefully shut down the server.* If you have installed BaseX on ''Windows'', click on the '''BaseX HTTP Server (Start)''' icon. The services can be deployed as follows:
* as standalone application by running the Various [[StartupCommand-Line_Options#HTTP Server|BaseX HTTP Servercommand-line options]],* as web servlet in a are available to simplify batch processing. The [[#Servlet ContainerStart_Scripts|Servlet Container]], and* as web servlet, using [[#Maven|Mavenstart script]]can be adjusted for individual purposes (e.g. if the default memory limit is too restrictive).<br/><br/>
=Servlet Container=An instance of the [https://www.eclipse.org/jetty/ Jetty Web Server] will be started, which by default listens to the port {{Code|8984}}. Additionally, the BaseX [[Database Server]] will be started, accessible on port {{Code|1984}}. The command-line output will look something like that (the JSP warning message [http://stackoverflow.com/questions/3521654/missing-jsp-support-in-jetty-or-confusing-log-message can be ignored]):
Configuring port, context path, etc. can be done by following the corresponding instructions of the used servlet container{| class="wikitable" |- valign="top"! Name! Standard Path!

If run on The [[DBA]] is a Jetty server web-based database administration interface written in RESTXQ. It allows you may use a {{Code|jetty.xml}} file for detailed server configuration. You can e.g. enable SSL connections or Jetty logging. Place the {{Code|jetty.xml}} right next to the {{Code|webcreate and administrate databases, evaluate queries in realtime, view log files, manage users, etc.xml}}. For detailed configuration refer to It is embedded in the [full distributions of BaseX, and it can be accessed after startup via http://wiki.eclipse.org/Jetty/Reference/jetty.xml Jetty Documentation]. A sample [httpslocalhost:8984/dba/github.com/BaseXdb/basex/blob/master/basex-api/src/main/webapp/WEB-INF/jetty.xml jetty.xml] is placed in the basex-api package.
To run on [http://tomcat.apache.org/ Apache Tomcat], start the tomcat server and add any <code>*.war</code> distribution to deploy using the Tomcat web interface. By default, the interface is accessible via http://localhost:8080/manager/html/.=Configuration=
==Configuration==Unless BaseX is deployed as servlet, the location of the web application directory can be adjusted via the {{Option|WEBPATH}} option, and compression of HTTP responses can be enabled via the {{Option|GZIP}} option.
All Further database options can be specified defined as context parameters in the {{Code|web.xml}} file.They need to be represented as context parameters and prefixed with {{Code|org.basex.}}.The most important options for the web application context are as follows:
|<code>[[Options#USER|USER]]</code>|{{CodeOption|adminUSER}}| Applies to REST and WebDAV service: If no user is specified, the credentials must be passed on by the client. Please check by yourself if it is safe to store your credentials in plain text.|-|<code>[[Options#USER|PASSWORD]]</code>
Path All options are prefixed with {{Code|org.basex.}}. Local file paths in options may contain an be absolute or relative path. If a relative path is specified, its root will be the servlet servlet’s ({{Code|webapp}}) path:
<context-param> <param-name>org.basex.dbpath</param-name> <!-- will be rewritten to ..../webapp/WEB-INF/data --> <param-value>WEB-INF/data</param-value> </context-param> <context-param> <param-name>org.basex.repopath</param-name> <!-- will be kept as is --> <param-value>f:/basex/repository</param-value> </context-param>

Execute <code>mvn install</code> in the <code>basex-core</code> project folder and then <code>mvn install jetty:run</code> in the <code>basex-api</code> project folder. This will start a Jetty instance in which the servlets will be deployed. ==Configuration== The same options as in the case of deployment in a servlet container apply.

Instead, Jetty looks up all files in the directory <code>[https://github.com/BaseXdb/basex/tree/master/basex-api/src/main/webapp basex-api/src/main/webapp]</code>. Jetty and servlet options can be configured in the {{Code|jetty.xml}} and {{Code|web.xml}} files as described above in the [[#Configuration|Servlet Container Configuration]]. The Jetty stop port can be changed in the [http://docs.codehaus.org/display/JETTY/Maven+Jetty+Plugin Maven Jetty Plugin] sesion in the {{Code|pom.xml}} file. =User Management= By default, the REST and WebDAV services require client-side authentication.Default credentials can be stored server-side in the <code>web.xml</code> file or specified via[[Command-Line Options#BaseX HTTP Server|command-line arguments]].If the HTTP server is started with no pre-defined credentials, users and passwords can be sent via[http://en.wikipedia.org/wiki/Basic_access_authentication HTTP Basic Authentication] or[http://en.wikipedia.org/wiki/Digest_authentication Digest Authentication].
With cURL, and most browsers, you can specify the user name and password with each HTTP request within the request string as plain text, using the format <code>USER:PASSWORD@URL</code>. An example:=Changelog=
=Changelog=;Version 8.6* Updated: Authentication readded to RESTXQ.* Updated: No password must be specified in the <code>web.xml</code> file anymore.* Updated: Server-side user and authentication method is now enforced (cannot be overwritten by client).
→Configuration
This page is part of the [[Getting Started]] Section. It describes how BaseX can be used as [[Web Application]]to both provide simple APIs and build complex web applications. The following three HTTP services are available:
<pre class="brush:xml">BaseX [HTTP Server][main] INFO org.eclipse.jetty.util.log - Logging initialized @375ms to org.eclipse.jetty.util.log.Slf4jLog[main] INFO org.eclipse.jetty.server.Server - jetty-9.4.21.v20190926; built: 2019-09-26T16:41:09.154Z; git: 72970db61a2904371e1218a95a3bef5d79788c33; jvm 13+33[main] INFO org.eclipse.jetty.webapp.StandardDescriptorProcessor - NO JSP Support for /, did not find org.eclipse.jetty.jsp.JettyJspServlet...Server was started (port: 1984).HTTP Server was started (port: 8984).HTTP STOP Server was started (port: 8985).</pre> After startup, you can access an HTML welcome page via http://localhost:8984. The Jetty logging level can be adjusted by adding the following properties to the start script: <pre class="brush:xml">-Dorg.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.StdErrLog -D{classref}.LEVEL=DEBUG</pre> BaseX can also be deployed as web servlet in a servlet container or with Maven: ==Servlet Container== In order to deploy BaseX HTTP Services in a servlet container, you may can download the WAR distribution of BaseX from the [http://basex.org/download download site] , or compile it via by calling <code>mvn compile war:war</code> in the <code>basex-api</code> packagedirectory. The WAR file can then be deployed following the instructions of the corresponding servlet container ([http://www.eclipse.org/jetty/documentation/current/quickstart-deploying-webapps.html jetty], [http://tomcat.apache.org/tomcat-7.0-doc/deployer-howto.html tomcat], etc.). You can configure the port, context path, etc. by following the instructions of the corresponding servlet container. This is needed if you want to replace the default URL path (e.g. http://localhost:8080/rest) with a custom one (e.g. http://localhost:8984/basex/rest). If you use Jetty (which is the default HTTP server of BaseX), the server configuration is available via the {{Code|jetty.xml}} file, which is stored in the {{Code|WEB-INF}} directory next to the {{Code|web.xml}}. For detailed configuration refer to the [http://www.eclipse.org/jetty/documentation/current/jetty-xml-config.html Jetty Documentation]. To run on [http://tomcat.apache.org/ Apache Tomcat], start the Tomcat server and add any <code>*.war</code> distribution to deploy via the Tomcat web interface. By default, the interface is accessible via http://localhost:8080/manager/html/. ==Maven== Check out the BaseX sources via [[Developing with Eclipse|Eclipse]] or [[Git]]. Execute <code>mvn install</code> in the main project directory and then <code>mvn install jetty:run</code> in the <code>basex-api</code> sub-directory. This will start a Jetty instance in which the servlets will be deployed. The same options as in the case of deployment apply in a servlet container. In this case, however, there is no WAR archive. Instead, Jetty looks up all files in the directory <code>[https://github.com/BaseXdb/basex/tree/master/basex-api/src/main/webapp basex-api/src/main/webapp]</code>. Jetty and servlet options can be configured in the {{Code|jetty.xml}} and {{Code|web.xml}} files as described above in the [[#Configuration|Servlet Container Configuration]]. The Jetty stop port can be changed in the [http://docs.codehaus.org/display/JETTY/Maven+Jetty+Plugin Maven Jetty Plugin] sesion in the {{Code|pom.xml}} file. =Services= The following services are available and enabled by default:
{| class="wikitable"

|{{Code|admin}}
| Applies to REST and WebDAV service: If no password a user is specified, it no credentials must be passed on by the client. Please check by yourself if it is safe to store your credentials in plain text.
|-
|<code>[[Options#HTTPLOCAL{{Option|HTTPLOCAL]]</code>}}
|{{Code|false}}

|-
|<code>[[Options#RESTXQPATH{{Option|RESTXQPATH]]</code>}}
|{{Code|.}}
|Relative or absolute directory referencing the [[RESTXQ]] modules. By default, the option points to the standard web application directory.

|<code>[[Options#RESTPATH{{Option|RESTPATH]]</code>}}
|{{Code|.}}
|Relative or absolute directory referencing queries and command-scripts that can be invoked via the [[REST#GET_Requests|run operation]] of REST. By default, the option points to the standard web application directory.

Context parameters can be requested from XQuery via [[Process_Module#proc:property-names|proc:property-names]] and [[Process_Module#proc:property|proc:property]]. How to set these options is specific to the servlet container. For example, in Jetty it can be done by [http://www.eclipse.org/jetty/documentation/current/override-web-xml.html overriding the web.xml] file. Another option is to directly edit the {{Code|WEB-INF/web.xml}} file in the WAR archive (WAR files are simple ZIP files). Refer to the sample [https://github.com/BaseXdb/basex/blob/master/basex-api/src/main/webapp/WEB-INF/web.xml web.xml] of the basex-api package.
To enable or disable a specific service, the corresponding servlet entry in the {{Code|web.xml}} file needs to be removed/commented. ==Authentication== Different credentials can be assigned to the REST and WebDAV a service by specifying local init parameters. In the following example, specific credentials are set an alternative user is specified for the REST service:
<pre class="brush:xml">
</pre>
Users are specified in a {{Code|users.xml}} file, which is stored in the database directory (see [[User Management]] for more information).
;Version 9.0* Updated: <code>http://admin:admin@localhost:8984/jetty.xml</code>configuration file (required for Jetty 9).
