To develop with INTGeoServer v3, you need have Java J2SE 1.8.0 (also called Java 8) or Java 11 installed on your computer (Mac, PC, Unix/Linux). Only 64 bit versions of Java can be used. You may use OpenJDK for Java 11.

The Java Development Kit (JDK) must be installed to develop INTGeoServer plugins: while the Java Runtime Environment (JRE) can be used to run INTGeoServer, it cannot be used for the development of plugins. To install the Oracle JDK, go to http://www.oracle.com/technetwork/java/javase/downloads/index.html. You need to have some Java development experience to create modules in INTGeoServer. You do not need Java experience to develop INTGeoServer clients as the web services only involve language-agnostic concepts such as the HTTP protocol and the JSON format.

Application Server

Because INTGeoServer uses the Java Servlet technology, it can run on virtually any application server supporting:

• the 3.1 Servlet specification (the 3.1 specification is needed for asynchronous services)

• the 1.1 WebSocket specification

Tomcat 8.5 is the minimum version of Tomcat supporting the Servlet and WebSocket specification. GlassFish 4.1 is the minimum version of GlassFish supporting the Servlet and WebSocket specification

In this documentation, we assume that Tomcat is used on a machine whose DNS name is myserver.mycompany.com. The port number in all examples is 8080, which is the Tomcat default port number.

IDE

You can use any IDE of your choosing. All examples in this site use the NetBeans IDE (downloaded from https://netbeans.apache.org/download/nb120/nb120.html), but you can use Eclipse as well.
