V případě, že má někdo podobný problém, lze jej vyřešit takto:
public class CallSPTest
{
public static STRUCT createSTRUCT(oracle.sql.StructDescriptor structDescriptor,
java.sql.Connection connection, java.lang.Object[] objects)
throws java.sql.SQLException
{
return new STRUCT(structDescriptor,connection,objects);
}
public void testSP(Session s)
{
t = s.beginTransaction();
s.doWork(new Work()
{
@Override
public void execute(Connection connection) throws SQLException
{
try
{
CallableStatement cs = connection.prepareCall("call SP_TEST(?)");
final Object[] values = new Object[]{1,2};
java.sql.Connection connect =
org.hibernate.jdbc.BorrowedConnectionProxy.getWrappedConnection(connection);
C3P0ProxyConnection castCon = (C3P0ProxyConnection) connect;
Method m = StructDescriptor.class.getMethod("createDescriptor", new Class[]{ String.class,Connection.class});
Object[] args = new Object[]{"MyType",C3P0ProxyConnection.RAW_CONNECTION};
StructDescriptor desc1 =(StructDescriptor) castCon.rawConnectionOperation(m, null, args);
Method m2 = CallSPTest.class.getMethod("createSTRUCT",
new Class[]{StructDescriptor.class, Connection.class,Object[].class});
args = new Object[] {desc1,C3P0ProxyConnection.RAW_CONNECTION,values};
final STRUCT struct1 = (STRUCT)castCon.rawConnectionOperation(m2,null,args);
cs.setObject(1, struct1, Types.STRUCT);
int aff_rows = cs.executeUpdate();
}
catch (Exception e)
{
System.out.print(e.getMessage());
}
}
});
}
catch (Exception e)
{
System.out.print(e.getMessage());
}
finally
{
if (null != t)
{
t.rollback();
}
}
}
