Thanks Mark! For some reasons I thought an epsg-wkt or epsh-hsql would
be needed. Ah, that is only for AUTHORY support.
Right. If you don't need to parse strings like "EPSG:4326", you don't
need any "gt2-epsg-foo.jar" file.
For a quick test creating a CRS from a WKT the only libraries required
were geoapi.jar, gt2-referencing-2.2-RC0.jar and JAI. The test just
converted a point from WGS84 to UTM-10N (The example used on
http://www.geotools.org/display/GEOTOOLS/Coordinate+Transformation+Services+for+Geotools+2.1).
Definitely fails without JAI. I'll do some more tests later in the week.
Thats strange; the referencing module is not supposed to requires JAI
anymore. I would be interrested to known the stack trace that you get,
in order to fix this bug.
A number of other jars are referenced in the CLASSPATH entry in the
metadata of gt2-referencing but weren't necessary for this test.
The Class-Path entry in META-INF/MANIFEST.MF (for the JAR built by Maven
2) is:
Class-Path: jsr108-0.01.jar jts-1.6.jar vecmath-1.3.1.jar geoapi-2.0.jar
- jsr108 should be required; I would be surprised if anything work
without that one.
- The jts dependency will disaspear in Geotools 2.3. They were only two
methods using JTS, and I deprecated them in release 2.2 (actually
moved them in an other package in the main module) so we can delete
them from the referencing module in 2.3.
- vecmath is going to be necessary as soon as coordinate transformations
will be involved. It is used for matrix operations.
- geoapi is of course required.
