Runtime Exception when connecting to Oracle

I am seeing this error message while trying out sqoop:

./sqoop import --connect jdbc:oracle:thin:@//archer.corp.apple.com:1525/xcardd --username xxx --password yyy --table zzz

I installed CDH3b2 on my Mac OS via tar files, installed hadoop, hbase, zookeeper, hive, before trying out sqoop. I have previously installed other products (hadoop, hbase, zookeeper, hive) with apache distribution, and they are all working out fine. moving everything to cloudera distribution just because of sqoop. thanks for your help!
