Changes

==Getting Started==

* the '''Core Package''' is a JAR file, which contains the database codesystem, 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, [[Starts Start Scripts]], and some additional optional files.* the '''WAR ApplicationArchive''' can be embedded in existing Java web servers.

* as [[#Web ApplicationHTTP Server|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 [http://www.java.com Java] Runtime Environment (JRE)].Since <b>Version 89.0</b> of BaseX, Java 7 8 is required. BaseX 8.x works with Java 7, because it provides better file handling support,and because Oracle stopped public support for older previous versionswere based on Java 6.

====Concurrent Operations====

If you plan to perform concurrent read and write operations on a single databasedatabases, youshould must use the client/server architecutre architecture or deploy it BaseX as web application.You may can safely open the same a database in different JVMs (Java virtual machines) forread-only access, and you won’t will not encounter any problems when reading from or and writingto different databases, but your update operations from different JVMs to the same database will be rejected if or may even lead to corrupt databases. More details are found in the databaseto be written to is currently opened by another virtual machine[[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 [[Command-Line Options#BaseX Standalone|Startup Options]]):

==Graphical User Interface==

The GUI It can be started as follows (get more information on all [[Command-Line Options#BaseX GUI|Startup Options]]):

==Client/Server==

===Server===

(get more information on all [[Command-Line Options#BaseX Server|Startup Options]]):

* On ''Windows'': Double click on the '''BaseX Server''' icon, which will also start the [[#BaseX HTTP Server|HTTP Server]], or the '''BaseX Server (stop)''' icon.

===Client===

(get more information on all [[Command-Line Options#BaseX Client|Startup Options]]):

We provide additional clients in various [[Clients|programming languages]] (language bindings), which allow you to communicate with BaseX from other programming lanaguges.

==Web Application=HTTP Server=

By defaultIt provides access to the [[REST]], an [[RESTXQ]] and [[WebDAV]] services.An instance of the [http://jetty.codehaus.org/jetty/ Jetty Web Server] is startedwill be created,which by default listens to the port {{Code|8984}}. Additionally, and the BaseX Serverwillbe started, which listens to is accessible on port {{Code|1984}}.

To run the HTTP Server, you need to [http://basex.org/products/download/ download] one of the full distributions of BaseX (exe, zip, war), as the JAR version does not include any additionally required libraries. It can then be started as follows(get more information on all [[Command-Line Options#BaseX HTTP Server|Startup Options]]):

* You BaseX can also deploy BaseX be deployed as a [[Web Application]]* For Maven users: type in {{Code|mvn jetty:run}} in the {{Code|basex-api}} directory, and press {{Code|Ctrl+c}} to shut down the process (see [[Web Application#MavenServlet Container|Web Application: Mavenweb servlet]] for more details).

In the first two cases, the command-line output will look similar to the following lines (the JSP warning message [http://stackoverflow.com/questions/3521654/missing-jsp-support-in-jetty-or-confusing-log-message can be ignored]): <pre class="brush:xml">[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@0.0.0.0:8984HTTP Server was started (port: 8984).</pre> You can adjust the Jetty logging level 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> After that, you can e. g. open your browser and navigate to the RESTXQ start page http://localhost:8984.
