xdi2 server

Implementation of an XDI server capable of responding to messages from XDI clients.

How to run the standalone XDI server

cd server
mvn jetty:run

Then (with default configuration) XDI endpoints are available at:

http://localhost:8080/xdi/mem-graph/
http://localhost:8080/xdi/bdb-graph/
http://localhost:8080/xdi/file-graph/

Server configuration

The XDI server's WEB-INF/web.xml should look like this (the root path /xdi/ may be modified):

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">

	<display-name>xdi2-server</display-name>

	<!-- XDI SERVER -->

	<servlet>
		<servlet-name>EndpointServlet</servlet-name>
		<servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
	</servlet>

	<servlet-mapping>
		<servlet-name>EndpointServlet</servlet-name>
		<url-pattern>/xdi/*</url-pattern>
		<url-pattern>/xdi/</url-pattern>
	</servlet-mapping>

	<!-- SPRING -->

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

</web-app>

An XDI server is backed by one or more XDI messaging targets, which in turn are typically backed by XDI graphs.

The XDI server can be configured with the file WEB-INF/applicationContext.xml, e.g.:

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd">

<!-- XDI Servlet -->

<bean id="EndpointServlet" class="xdi2.server.EndpointServlet" />

<!-- Messaging Targets -->

<bean id="graphfactory1" class="xdi2.core.impl.memory.MemoryGraphFactory" />

<bean id="graph1" factory-bean="graphfactory1" factory-method="openGraph" />

<bean name="/mem-graph" class="xdi2.messaging.target.impl.graph.GraphMessagingTarget">
	<property name="graph" ref="graph1" />
</bean>

</beans>

The above configuration file sets up an XDI endpoint backed by an in-memory store at path /mem-graph
