Get thumbnail for DICOM

Question

Hi,
Could you please show me a way how I could use Oracle Multimedia DICOM java API to generate thumbnail for DICOM?
I use the table you describe at http://www.oracle.com/technology/obe/11gr1_db/datamgmt/dicom/dicom.htm. I get the OracleResultSet from Oracle database after executing sql like "select * from medical_image_table". The OracleResultSet could be interpreted to OrdDicom in the following way: OrdDicom dicom = (OrdDicom)dicomSet.getORAData("dicom", OrdDicom.getORADataFactory()). How could I get a thumbnail with the dicom?
I see some materials that should call setProperties and processCopy. But it always always throw the exception that the data model is not loaded. How could I load the data model when I am using the Oracle Multimedia java API?
Calling getAttributeByName leads the same error.
Regards,
Emily

Answer 1

I have solving it by setting data model for the connection in the following way:
void setDataModel(Connection conn) throws SQLException {
     CallableStatement cs = null;
     try {
     cs = conn.prepareCall("begin ord_dicom.setDataModel(); end; ");
     cs.execute();
     cs.close();
     } catch(SQLException se) {
     System.out.println("Calling ord_dicom.setDataModel");
     cs.close();
It works and I could get the thumbnail from DICOM. Thanks anyway!
