I am not exactly sure what you are asking. Consider posting a minimal but
complete code (JSP, Java) example to help us understand if the following
info doesn't help:
Hashtable.elements() returns an Enumeration of the values, not the keys. I
believe that logic:iterate will just iterate though the Enumeration of
values.
hash.contains(new String("one")) will return false in your example code,
because there is no map entry with a value of "one". I think you mean
hash.containsKey("one"), which is much faster and will return true. Read the
API docs:
http://java.sun.com/j2se/1.4.1/docs/api/java/util/Hashtable.html
Also, the newer HashMap class might be faster than Hashtable, since HashMap
is not synchronized.

Subject: how to get a single value from hashtable
hi
i am using the struts and jstl in my web application and using the
logic:iterate for iterating the hashtable,arraylist.
I faced the problem at this point:-
i am getting any tag for retrival of only one value from the hashtable that
we are getting through java function.
ex:-
Hashtable hash=new Hashtable();
hash.put("one","first");
hash.put("two","second");
the code i am using in java is
if(hash.contains(new String("one"))
String value=hash.get(new String("one"))
but i am not getting this using struts or jstl
Please help me
Regards
