The Jetty logging level can be adjusted by adding the following properties to the start script:
<syntaxhighlight pre lang="xml">

</syntaxhighlightpre> Various [[Command-Line_Options#HTTP Server|command-line options]] are available to simplify batch processing. The [[Start_Scripts|start script]] can be adjusted for individual purposes (e.g. if the default memory limit is too restrictive).
BaseX can also be deployed as web servlet in a servlet container or with Maven:
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:8080/basex/rest).
If you use Jetty (which is the default HTTP server of BaseX), the server configuration is available via defined in 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 [https://www.eclipse.org/jetty/documentation/current/jetty-xml-config.html Jetty Documentation].
To run on [https://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-directorysubdirectory. 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 [https://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html Maven Jetty Plugin] sesion in the {{Code|pom.xml}} file.
The following services are available and enabled by default:
{| class="wikitable"
|- valign="top"
! Name
{| class="wikitable"
|-valign="top"
! width="160" | Option
! width="90" |Default
! Description
|-valign="top"
|{{Option|USER}}
|{{Code|admin}}
| If a user is specified, no credentials must be passed on by the client.
|-valign="top"
|{{Option|HTTPLOCAL}}
|{{Code|false}}
|Operation mode. By default, a database server instance will be started, as soon as the first HTTP service is called. The database server can be disabled by setting this flag to {{Code|true}}.
|-valign="top"
|{{Option|RESTXQPATH}}
|{{Code|.}}
|Relative or absolute directory referencing the [[RESTXQ]] modules. By default, the option points to the standard web application directory.
|-valign="top"
|{{Option|RESTPATH}}
|{{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.
|-valign="top"
|{{Option|AUTHMETHOD}}
|{{Code|Basic}}
All options are prefixed with {{Code|org.basex.}}. Local file paths in options may be absolute or relative. If a relative path is specified, its root will be the servlet’s ({{Code|webapp}}) path:
<syntaxhighlight pre lang="xml">
<context-param>
<param-name>org.basex.dbpath</param-name>
<param-value>f:/basex/repository</param-value>
</context-param>
</syntaxhighlightpre>
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 {{Code|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 No credentials can need to be supplied if a default user is assigned to a service by specifying local init parametersin the {{Code|web.xml}} file. In the following example, an alternative the user {{Code|rest-user }} is specified for the REST service:
<syntaxhighlight pre lang="xml">
<servlet>
<servlet-name>REST</servlet-name>
</init-param>
</servlet>
</syntaxhighlightpre>
If the HTTP server is started with no pre-defined user, the credentials must be passed on by the client via [https://en.wikipedia.org/wiki/Basic_access_authentication Basic Authentication] or [https://en.wikipedia.org/wiki/Digest_authentication Digest Authentication] (, depending on the server setting)chosen authentication method in the configuration.
With cURL, internet browsers, and other tools, you can specify basic authentication credentials within the request string as plain text, using the format <code>USER:PASSWORD@URL</code>. An example:
: <code>http://admin:admin...@localhost:8080/</code>
Users are specified in a {{Code|users.xml}} file, which is stored in the database directory (see [[User Management]] for more information).
