Example

H2GISDataStoreFactory factory = new H2GISDataStoreFactory();
factory.setBaseDirectory(new File("./target/testH2"));
HashMap params = new HashMap();
params.put(JDBCDataStoreFactory.NAMESPACE.key, "http://www.h2gis.org/test");
params.put(JDBCDataStoreFactory.DATABASE.key, "mydatabase");
params.put(JDBCDataStoreFactory.DBTYPE.key, "h2gis");
JDBCDataStore ds = factory.createDataStore( params );
Statement st = ds.getDataSource().getConnection().createStatement();
st.execute("drop table if exists FORESTS");
st.execute("CREATE TABLE FORESTS ( FID INTEGER, NAME CHARACTER VARYING(64), THE_GEOM MULTIPOLYGON);
INSERT INTO FORESTS VALUES(109, 'Green Forest', ST_MPolyFromText( 'MULTIPOLYGON(((28 26,28 0,84 0,84 42,28 26), 
(52 18,66 23,73 9,48 6,52 18)),((59 18,67 18,67 13,59 13,59 18)))', 101));");

SimpleFeatureSource fs = (SimpleFeatureSource) ds.getFeatureSource("FORESTS");
SimpleFeatureType schema = fs.getSchema();
Query query = new Query(schema.getTypeName(), Filter.INCLUDE);

System.out.println(fs.getCount(query));
System.out.println(schema.getAttributeCount());
