Savepoint not supported with oracle 8i

Question

when I am using the oracle thin driver I'm getting the following error
Exception in thread "main" java.lang.AbstractMethodError: oracle.jdbc.driver.OracleDatabaseMetaData.supportsSavepoints()Z
at Svpt1.main(Svpt1.java:31)
but when odbc driver is used the
Checking savepoint support ...
Savepoint is not supported
Insert record(10, 'newregion1') ...
Establish savepoint 1 ...
Unexpected Exception null
java.lang.UnsupportedOperationException
at sun.jdbc.odbc.JdbcOdbcConnection.setSavepoint(JdbcOdbcConnection.java
:1713)
at Svpt1.main(Svpt1.java:49)
please tell me why this difference and how can I use savepoint with oracle 8i.
I'm using Oracle 8i and j2sdk1.5.0_06
