This page is part of the Developer Section. The following Java code snippets demonstrate how easy it is to run database commands, create collections, perform queries, etc. by integrating the BaseX code. Most examples are taken from our basex-examples repository, in which you will find some more use cases.
Local Examples
- RunCommands.java
creates and drops database and index instances, prints a list of all existing databases. - RunQueries.java
shows three variants of running queries. - BindContext.java
demonstrates how a value can be bound as context item. - BindVariables.java
demonstrates how a value can be bound to a variable. - CreateCollection.java
creates and manages a collection. - QueryCollection.java
creates, runs queries against it and drops a collection. - WikiExample.java
creates a database from an url (wiki instance), runs a query against it and drops the database.
Server Examples
- ServerCommands.java
launches server-side commands using a client session. - ServerAndLocal.java
processes server results locally. - ServerConcurrency.java
runs concurrent queries. - ServerQueries.java
shows how iterative queries can be performed. - UserExample.java
manages database users. - ServerEventsGUI.java
is a little GUI example for demonstrating database events.
XQuery Module Examples
- FruitsExample.java
demonstrates how Java classes can be imported as XQuery modules. - FruitsModule.java
is a simple demo module called byFruitsExample
. - ModuleDemo.java
is a simple XQuery demo module that demonstrates how XQuery items can be processed from Java. It is derived from theQueryModule
class. - ModuleDemo.java
is a simple XQuery demo module that demonstrates how XQuery items can be processed from Java. It is derived from theQueryModule
class. - QueryModule.java
Java query modules can extend this class to get access to the current query context and enrich functions with properties (see more).
XQJ API
Our current XQJ API is based on Charles Foster’s XQJ implementation (closed-source). It communicates with the BaseX server. The basex-examples repository contains various examples on how to use XQJ.
Client API
- BaseXClient.java
provides an implementation of the Server Protocol. - Example.java
demonstrates how commands can be executed on a server. - QueryExample.java
shows how queries can be executed in an iterative manner. - QueryBindExample.java
shows how external variables can be bound to XQuery expressions. - CreateExample.java
shows how new databases can be created. - AddExample.java
shows how documents can be added to databases, and how existing documents can be replaced. - EventExample.java
demonstrates how to trigger and receive database events. - BinaryExample.java
shows how binary resource can be added to and retrieved from the database.
REST API
- RESTGet.java
presents the HTTP GET method. - RESTPost.java
presents the HTTP POST method. - RESTPut.java
presents the HTTP PUT method. - RESTAll.java
runs all examples at one go.
XML:DB API (deprecated)
Note that the XML:DB API does not talk to the server and can thus only be used in embedded mode.
- XMLDBCreate.java
creates a collection using XML:DB. - XMLDBQuery.java
runs a query using XML:DB. - XMLDBInsert.java
inserts a document into a database using XML:DB.
