Use Hashtable in multithreaded environment, in others use HashMap.
In Hashtable, the addition/retreival methods are synchronized.
A synchronized method can be accessed by ONLY by a single thread at a time. Other threads wait for this sync. method till the currently executing thread is done.
Performance would be less using Hashtable when compared to HashMap.
Use Hashtable ONLY in multi-threaded environment.

hashmap is better because it is asynchronous multiple clients can acess at a time.But in case of hashtable it is synchronous ie (legacy collection)

Criteria for finding out the suitability of HashMap & HashTable for a given purpose is independant of weather u use any of them in EJB or Java Bean or a normal java class.
So choose which one is suitable for your requirement and go ahead and use it in ur EJB.

Use HashMap's .. hashtable is a legacy datastructure
