Should I use a static variable or Hashtable to store a list of strings?
The static modifier for a variable is different from the object type of the variable. If you want all servlet instances to be able to read and write data to a field, it should be static. Depending on the nature of the application, it may also be necessary to synchronize access to the variable. If you want to store a simple list of strings, a java.util.List type variable would be most appropriate. A Vector is a List type and its implementation is synchronized.
