Data size limit on long column

Question

I saw one of the Oracle JDBC FAQ saying 8.0x thin driver does not
support long column with data size >2k using setString.
is there any latest Oracle driver support long column with data
size > 2k ?
null

//this sample will create the table
//just modify the connect string. will work with thin and oci
drivers
