This article is part of the Getting Started Guide. It tells you how to get BaseX running.
Contents
Getting Started
First of all, download BaseX from our homepage. The following distributions are available:
- the Core Package is a JAR file, which contains the database system, the query processor and the GUI frontend. It is runs completely without additional libraries.
- the ZIP Archive and the Windows Installer contain libraries for web applications and advanced features, Start Scripts, and some additional optional files.
- the WAR Archive can be embedded in existing Java web servers.
Some additional distributions are available from the download page, most of which contain only the core package and, optionally, scripts for starting BaseX.
BaseX is very light-weight. It can be run and used in various ways:
- as standalone application, using the Standalone mode or the Graphical User Interface,
- as Client/Server application, or
- as Web Application, called from a web server.
It can also be embedded as a library in your own application.
Requirements
BaseX is platform-independent and runs on any system that provides an implementation of the Java Runtime Environment (JRE):
- Since Version 9 of BaseX, Java 8 is required.
- Since Version 8, Java 7 is required.
- Older versions are based on Java 6.
BaseX has been tested on several platforms, including Windows (2000, XP, Vista, 7), Max OS X (10.x), Linux (SuSE xxx, Debian, Ubuntu) and OpenBSD (4.x).
Concurrent Operations
If you want to perform parallel (concurrent) read and write operations on your databases, you must use the client/server architecture or deploy BaseX as web application. You can safely open a database in different JVMs (Java virtual machines) for read-only access, and you will not encounter any problems when reading from and writing to different databases, but update operations from different JVMs to the same database will be rejected or may even lead to corrupt databases.
For example, if you only read data, you can easily run several clients (standalone, GUI, database clients) at the same time. If you update your data, however, you shouldn’t use the GUI or a standalone instance at the same time.
More details on concurrency are found in the Transaction Management article.
Standalone
The Standalone Mode can be used to execute XQuery expressions or run database commands on command line. It can also be used both for scripting and batch processing your XML data. It can be started as follows (get more information on all Startup Options):
- Run one of the
basex
orbasex.bat
scripts. - Execute the following command:
java -cp BaseX.jar org.basex.BaseX
- On Windows: Double click on the BaseX icon.
It is important to remember that the standalone mode does not interact with the Client/Server architecture.
Graphical User Interface
The GUI is the visual interface to the features of BaseX. It can be used to create new databases, perform queries or interactively explore your XML data.
It can be started as follows (get more information on all Startup Options):
- Double click on the
BaseX.jar
file. - Run one of the
basexgui
orbasexgui.bat
scripts. - Execute the following command:
java -cp BaseX.jar org.basex.BaseXGUI
- On Windows: Double click on the BaseX GUI icon.
- For Maven users: type in
mvn exec:java
in the main directory of thebasex
project.
Note that the GUI does not interact with the client/server architecture.
Client/Server
Server
The Database Server comes into play if BaseX is to be used by more than one user (client). It handles concurrent read and write transactions, provides user management and logs all user interactions.
By default, the server listens to the port 1984
.
There are several ways of starting and stopping the server
(get more information on all Startup Options):
- Run one of the
basexserver
orbasexserver.bat
scripts. Add thestop
keyword to gracefully shut down the server. - Execute the following command:
java -cp BaseX.jar org.basex.BaseXServer
. Again, thestop
keyword will ensure a graceful shutdown. - On Windows: Double click on the BaseX Server icon, which will also start the HTTP Server, or the BaseX Server (stop) icon.
Pressing Ctrl+c
will close all connections and databases and shut down the server process.
Client
The BaseX Client interface can be used to send commands and queries to the server instance on command line.
It can be started as follows (get more information on all Startup Options):
- Run one of the
basexclient
orbasexclient.bat
scripts. - Execute the following command:
java -cp BaseX.jar org.basex.BaseXClient
- On Windows: Double click on the BaseX Client icon.
The default admin
user can be used to connect to the server:
- Username:
admin
- Password:
admin
The password should be changed with the PASSWORD
command after the first login.
We provide additional clients in various programming languages.
HTTP Server
With the HTTP Server, BaseX can be used as Web Application.
It provides access to the REST, RESTXQ and WebDAV services.
An instance of the Jetty Web Server will be created,
which by default listens to the port 8984
. Additionally, the BaseX Server will
be started, which is accessible on port 1984
.
It can be started as follows (get more information on all Startup Options):
- Run one of the
basexhttp
orbasexhttp.bat
scripts. Call the script with thestop
keyword to gracefully shut down the server. - On Windows: Double click on the BaseX Server or BaseX Server (stop) icon.
- BaseX can also be deployed as web servlet.
In the first two cases, the command-line output will look similar to the following lines (the JSP warning message can be ignored):
[main] INFO org.eclipse.jetty.server.Server - jetty-8.1.18.v20150929 [main] INFO org.eclipse.jetty.webapp.StandardDescriptorProcessor - NO JSP Support for /, did not find org.apache.jasper.servlet.JspServlet [main] INFO org.eclipse.jetty.server.AbstractConnector - Started SelectChannelConnector@0.0.0.0:8984 HTTP Server was started (port: 8984).
You can adjust the Jetty logging level by adding the following properties to the start script:
-Dorg.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.StdErrLog -D{classref}.LEVEL=DEBUG
After that, you can e. g. open your browser and navigate to the RESTXQ start page http://localhost:8984.
Changelog
- Version 8.0
- Update: Switched to Java 7
- Version 7.0
- Updated: BaseXJAXRX has been replaced with BaseXHTTP
