Oracle OLAP ExpressDataProvider Exceptions

Question

Hi
I'm using Oracle 9i OLAP API. There's something strange going on here. I written a test program that accesses the metadata and displays all it's contents. It runs fine on my home PC. At college the same program running on the same settings as that of my home PC (including the jar files required) gives me the error shown by the staacktrace below:
Exception in thread "main" java.lang.AbstractMethodError: oracle.jdbc.driver.OracleConnection.getTypeMap()Ljava/util/Map;
at oracle.express.idl.util.TypeMapHelper.setTypeMap(TypeMapHelper.java:14)
at oracle.express.olapi.data.full.ExpressDataProvider.initialize(ExpressDataProvider.java:150)
at metadata.main(metadata.java:44)
Press any key to continue...
I am also sending the code below:

I dunno what's happening.Someone help with this please.
It's urgent
Thanx

Good questions and I have put them to the docs team to (1) update the online docs and (2) respond here. Let's see if they do.
