table from one schema to another

While creating table of another schema I have this problem.
 SQL>  create table MSDP_CHARGING_TRANSACTIONS as select * from wsuser.MSDP_CHARGING_TRANSACTIONS;
 create table MSDP_CHARGING_TRANSACTIONS as select * from wsuser.MSDP_CHARGING_TRANSACTIONS
                                                   *
ERROR at line 1:
ORA-00997: illegal use of LONG datatype

What is the solution.
