This turns out to be more a mystery than I first thought. I assumed the when
running under JPACKAGE, it was not finding the epsg database, but logs didn’t
show any sign of that. I requested stackdump in the exception, and I get:
org.opengis.referencing.NoSuchAuthorityCodeException: No code "EPSG:2193" from
authority "EPSG" found for object of type "EngineeringCRS".

Reading this, I would assume that it didn’t find the plugin at all. Relevant
bits of pom: <dependency>

<artifactId>gt-referencing</artifactId>
<version>${geotools.version}</version>
</dependency>
<dependency>
<groupId>org.geotools</groupId>

<artifactId>gt-epsg-extension</artifactId>

<type>jar</type>
</dependency>
( I been trying both wkt and h2sql plugins – same result for h2sql).
If I look at the shaded jar in the application image, I can see the plugin
classes. I am pretty hazy though about plugins work in java – what would be
reasons for the executable not to find them? As noted earlier, this works fine
if run as jar on a machine with java already installed.

If you have done sharing correctly then plugin discovery works.
The zip is unpacked into the the temp folder I believe? Yes it is:
File directory = new File(System.getProperty("java.io.tmpdir", "."),
"Geotools");
if (directory.isDirectory() || directory.mkdir()) {
directory = new File(directory, "Databases/HSQL");
if (directory.isDirectory() || directory.mkdirs()) {
return directory;
}
}
You can also set a property "EPSG-HSQL.directory" to indicate where the
database is located.

I have a little console app (pushing excel sheet to a database), that runs fine
as a shaded jar with java. However, I have folk using it that are reluctant to
install java and I packaged it with JRT etc using JPackage. If the code is
launched with JPackage, then it doesn’t find the EPSG database. Tried with both
epgl-h2sql and epsg-wkt. No luck. JPackage allows me to specify a resource
directory, but no idea what it would be. When the app runs, what exactly
happens to say the EPSG.zip in epsg-h2sql for instance?
