Solution Description

Reverse engineer your database structure into java JPA classes. Create Java classes, or an Xcore or Ecore representation of your exisiting database. g9 Database Model Import is a free g9 Eclipse plugin producing models based on structure information read from databases.

Given a connection to an existing database, the g9 Database Import will read tables and columns in your database (using the database schema) and create the corresponding model either in Java, Xcore or Ecore depending on the project type of your Eclipse project.

Install g9 Database Import, restart Eclipse and create a Java or Xcore project. Select File > Import... > g9 > Import Database Model to start the import wizard (see the Screenshots).

Complete documentation is available from Help > Help Contents. Select g9 Documentation >  g9 Database Model Import.


  • which tables to include: by default, all tables are included and a class name based on the table names is suggested
  • which columns to include: by default, all columns are included and an attribute name based on the column names is suggested
  • the data type mappings for your domain model based on the JDBC types - or use default values

An import of your database to a Java Project will create Java classes, an import to an Xcore Project will create an Xcore model, all other Eclipse Project types will result in an Ecore model. The Java classes may be enriched with JPA annotations. If you work with Xcore or Ecore models you should use Eclipse for Java and DSL Developers.

The g9 Database Import connects to a database using JDBC drivers. The built-in drivers are MySQL, MS SQL Server (jTDS) and Sybase ASE (jTDS). Use the function [Maintain JDBC Drivers] in the g9 Import feature to connect to other databases, e.g Oracle, PostgreSQL, Firebird or a DBMS of your choice.

You may download the complete g9 product and use the Database import feature in a g9 Eclipse Project. To be able to exploit the other features in g9, you should create a g9 UI Modeling Project and import your database to an Ecore, Xcore model or Java source with g9 annotations. Please see the User guide for more information about the g9 Database Import feature.

I've been working on this for a few days and I am at a loss. So I am able to connect to my DB connection via the g9 GUI after enterig mysql info in applicaiton properties (I am using Spring Tool Suite). When I click on "fetch table" it loads all the tables from mydb in mysql. I then go to next and it brings them up there for me to selection. So far so god. Then when I select "finish" it says "cannot read dbms table" and throws a communications link error. I know this is a common error, but idk what to add to the code or to application properties to get this to work. I have verified that the correct IP and host is being used. I have turned off the firewall. I have made sure to add autoreconnect and the correct timezone.Any advice on what is the issue? Is there an issue with tomcat? I have increased the time limit in mysql workbench as well and set it to * for the bind addresses. again, any other advice? 

This library does not show on my Marketplace for some reason. And when I drag the button via the browser, I only get the Featured libraries in the Marketplace client. Does any have the same issue?

In reply to by Per Digre

I have accepted cookies and I have already downloaded many plugins via the marketplace. The problem is I do not even get an error message. It seems as if the marketplace ignores the plugin and shows the default recommended list instead. I'd like to know if others have had this problem, too.

I have Eclipse Oxygen.3a Release (4.7.3a) installed and have created a Spring Data project using Spring Initializer with JPA and SQL Server dependencies. This library does not show up in the Marketplace when I search for it. So I scroll all the way down and click on "click for more solutions". This opens a tab in the Eclipse web browser in which I see the g9 Database Import in the search results. So I click on "Install". The marketplace is opened with no g9 in the results. This is slightly confusing.
