EPSG H2 PluginΒΆ
This plugin works out of the box (as a pure java database with its own copy of the EPSG database included).
To use place the gt-epsg-h2 jar on your CLASSPATH.
Although this plugin is not supported, it is a drop in replacement for the gt-epsg-hsql plugin and is well suited if you are already using H2 and do not want a second pure java database dependency in your application.
