Re: [Geotools-gt2-users] [ExternalEmail] Re: What's the difference between gt-postgis and gt-jdbc-postgis

[Yingqi T. <ana...@gm...>]

Just made it work, the problem turns out to be that I didn't include
gt-epsg-wkt as dependency. Once I add it, the srid 4326 is recognized as
WGS84.

<dependency>
            <groupId>org.geotools</groupId>
            <artifactId>gt-epsg-wkt</artifactId>
            <version>${project.version}</version>
        </dependency>

Thanks you all for the helpful info.
