STRUCT dbObject = (oracle.sql.STRUCT)rs.getObject("shape");
JGeometry geom = JGeometry.load(dbObject);

Answer 1

Hi, this is a known problem for most Spatial 10g Java APIs with WLS.
WLS is only certified with 11g DB.
Instead of using Weblogic JNDI Lookup for Datasource, try the following snippet to create your connection/datasource (with Oracle JDBC thin driver):
String databaseUrl = jdbc:oracle:thin:@1.2.3.4:1521:yourdbname
String databaseUser = dbusername
String databasePassword = dbpassword
DriverManager.registerDriver(new OracleDriver());
Connection aConnection = DriverManager.getConnection(databaseUrl, databaseUser, databasePassword);
