Description:

There are exception in When 1-digit value used for sdo_gtype.

As it written in Oracle documentation (http://docs.oracle.com/cd/B10500_01/appdev.920/a96630/sdo_objrelschema.htm#sthref192) in this case Oracle Spatial determines the number of dimensions from the DIMINFO column of the metadata views.

I can't find way to get schema and table name to check metadata view and use workaround:

make addition methods in OracleDialect

  • readGeometry with addition parameter int defaultDimension
    and add same parameter in GeometryConverter.asGeometry with small fix: 
            int _GType = asInteger( data[0], 0 );
        final int GTYPE = (_GType<1000)?_GType+defaultDimensions*1000:_GType;

    and change OracleDialect.decodeGeometryValue:

            Geometry geom = readGeometry( rs, column, factory, cx, descriptor.getCoordinateReferenceSystem().getCoordinateSystem().getDimension());
