GeoTools
GeoTools is a GIS toolkit that is used for OGC-based projects via GeoAPI interfaces. It includes two great SLD based renderers and tools for raster access and reprojection as well as plugins for Shapefile, ArcGrid, ArcSDE, Postgis, OracleSpatial, MySQL, and many more.

Release Notes: This release features several fixes in the WFS client, making it work against TinyOWS and the ArcGIS WFS server, and improvements in the usage of filter fuctions from SLD (some functions did not properly convert their arguments from string to numeric). Some tiling artifacts when rendering oversampled grid coverages were removed. FIDFilter objects in map rendering are now faster.

Release Notes: This is a bugfix release made in conjunction with uDig 1.2-RC3. It adds support for Oracle Georaster access and many small but interesting improvements, including interpolate functions which are very useful when styling maps. Generated SLD files no longer write out "default" values, which will make for a more readable result.

Release Notes: This release fixes an encoding problem from the shapefile attribute reader. WFSDataStore no longer hangs indefinitely on a connection. Inconsistent behavior in org.geotools.styling.StrokeImpl has been fixed. The 1.0 filter properly encodes FeatureId elements. A bug in the equalInterval function for non-numerical attributes has been fixed. CQL datetime values no longer throw an exception in Oracle. The encoder closes feature collections. A BBox filter with an empty property name should be supported.
- 08 Oct 2008 20:42
Release Notes: This marks the first stable release of a number of exciting developments and features of the 2.5.x series including a new feature model based on GeoAPI, Java 5, support for units based on JSR-275, and much more.
- 11 Feb 2008 13:36
Release Notes: Sgnificant speedups in shapefile and PostGIS data rendering. Many expressions improvements using converters to correctly handle a range of queries. Style interfaces now use the GeoAPI filter. This release can redirect to an alternate logging API, makes use of Java connection pools, and uses a registered java DataSource for the epsg database in a Java EE environment. Datastore dispose has been added. There is a user guide with a small section for 2.4.0. The ISO geometry implementation is available as a supported module. The community change proposal process has been adopted.

Wonderful API for GIS Apps. using Applet
Thanx to James and his team for their continous effort and dedication which has resulted into a wonderful Java API for GIS Apps.
I personally found the API very structured and featured which has been giving me constant thrill as I am exploring and learning the possibility.
At somepoint sometimes it is difficult to clearly intrepret the meaning but with little code it becomes a see-thru-crsytal.
I am glad to hit this site accidently. Thanx to google.
Cheers Guys
