Install Eclipse

Installing Eclipse is relatively easy, but does involve a few steps and software from at least two different sources. Eclipse is a Java-based application and, as such, requires a Java runtime environment (JRE) in order to run.

Note that on recent versions of Mac, a full JDK needs to be installed, not just a JRE; see instructions below.

Download Eclipse from the Eclipse Downloads Page.

There are several package choices. Note that you can install the features from any package into any other package, since Zamolxis is model based the best package to start with is "Eclipse Modeling Tools".

Install Zamolxis in Eclipse

Once you have one of the supported Eclipse versions installed you can add Zamolxis ERD via the "Help > Install New Software..." menu option. You need to add a new Software Site for Zamolxis, if not already present in the list of available sites. The location of the update site for Zamolxis product is

Select the Zamolxis update site to work with from the list of available sites, depending on the platform some features won't be available, it is recomended to only show those applicable to the target environment. Required dependencies will be automatically selected for download, make sure you read the license agreement before proceeding to install and restart Eclipse when prompted once the installation is complete.

Install Zamolxis in Progress Developer Studio for OpenEdge (PSDOE)

If you already have Progress Developer Studio for OpenEdge installed then you can just add Zamolxis into it via the "Help > Install New Software..." menu option. This will let you work from the same integrated development environment and also provide integration with Progress runtime for projects that have a Progress OpenEdge nature.

Install a JVM

Regardless of your operating system, you will need to install some Java virtual machine (JVM). You may either install a Java Runtime Environment (JRE), or a Java Development Kit (JDK), depending on what you want to do with Eclipse. If you intend to use Eclipse for Java development, then you should install a JDK. If you aren't planning to use Eclipse for Java development and want to save some disk space, install a JRE.

    • If you're using Windows, you may already have a JRE installed, but upgrading won't hurt.
    • If you're using Mac, and you don't have a JDK installed, you may get a bogus message from the OS stating that you should "install the legacy Java SE 6 runtime". Installing that will not solve the problem, because recent versions of Eclipse require a higher version. If you install just a JRE, and not a full JDK, that error message will persist. You must install a full JDK.
