The installation instructions for the SAVARA Eclipse tools are:
Eclipse
Download the latest version of Eclipse JEE, from http://www.eclipse.org, and install in your environment.
Savara Eclipse Tools
Start up your Eclipse environment, and go to the Help->Install New Software.. menu item. Select the appropriate update site URL from the SAVARA Downloads page. Once the contents of the update site is available, then select the Savara and Savara Dependencies categories and follow the instructions to install them within your Eclipse environment.
One of the supported runtime platforms, for which Savara can be used to generate and test service implementations, is the SwitchYard ESB. This project includes some Eclipse tooling which is required when generating SwitchYard services. To install these tools, following the instructions here: https://docs.jboss.org/author/display/SWITCHYARD/Installing+Eclipse+Tooling
(only need to install separately if not installing SwitchYard tools)
The Savara tooling is now focused around BPMN2 for representing choreographies and process models. If you do not have a BPMN2 modelling tool, then we recommend installing the free open source tool from Eclipse (http://eclipse.org/bpmn2-modeler/).
(only need to install separately if not installing SwitchYard tools)
The Savara tooling can be used to generate BPEL processes, either standalone or as part of a Switchyard project (from version 2.1). If a BPEL editor is required, to view the process definitions graphically, then install the free open source tool from Eclipse (http://www.eclipse.org/bpel/).
