Installation


Download

Download the latest XAP release

Installation

  • Unzip the distribution into a working directory; GS_HOME
  • Set the JAVA_HOME environment variable to point to the JDK root directory
  • Start your favorite Java IDE
  • Create a new project
  • Include all jar files from the GS_HOME/lib/required in the classpath

Maven

XAP is Maven-friendly - it is built using maven and designed to be easily used by developers constructing XAP applications.

The main dependency required to use XAP is xap-openspaces

 <dependency>
   <groupId>org.gigaspaces</groupId>
   <artifactId>xap-openspaces</artifactId>
   <version>12.0.1</version>
 </dependency>

Since XAP artifacts are currently not published in Maven Central Repo, you’ll also need to configure a repository:

 <repository>
    <id>org.openspaces</id>
    <url>http://maven-repository.openspaces.org</url>
 </repository>

Examples

There are two examples provided with the Open Source distribution. You can find them under the <XAP root>/examples directory. The examples are also available on github(see links below).

Hello World
The Hello World example demonstrates how to perform basic Space operations - e.g. writing and reading an Object from the data-grid. This example also covers different deployment modes: embedded, remote and partitioned.

Hola Mundo
This example builds on the previous example, introducing the concepts of event-processing using a Processing Unit. This example also demonstrates how to run with the IDE.
