Hi All-
After a 5 year hiatus, I am getting re-acquinted with GeoTools. I have
downloaded a copy of "geotools-2.7-RC2-bin" and I'm writing a simple app to
process a GridCoverage2D. Out of the gates, I can't seem to get past a
"NoClassDefFoundError: javax/media/jai/OperationRegistrySpi". Here's the code:
BufferedImage bi = ImageIO.read(
new File("C:/My Documents/earth.jpg"));
Envelope2D envelope = new Envelope2D(CRS.decode("EPSG:4326"),
new java.awt.geom.Rectangle2D.Float(-180f, -90.0f, 180f, 90f)
);
GridCoverage2D gc2d = new GridCoverageFactory().create("BMImage", bi, envelope);
It's bombing out on the create() method saying:
Exception in thread "main" java.lang.NoClassDefFoundError:
javax/media/jai/OperationRegistrySpi

org.geotools.coverage.grid.GridCoverageFactory.create(GridCoverageFactory.java:455)
...
Note that the binaries I downloaded seem to have all the requisite jar files
*EXCEPT* jai_core.jar. I see "jai_codec-1.1.3.jar" and "jai_imageio-1.1.jar"
but
I had to add "jai_core.jar" (JAI 1.1.3 alpha) to my project to even get to this
point.
I can import "javax.media.jai.OperationRegistrySpi" without any problems (no
build or compile errors). If I take out "jai_core.jar", the import fails.
I know must be missing another jar file or something simple. Any suggestions?
Thanks in Advance!
Peter
