Hi Max
Sorry for writing the wrong code.
In my code :
---
Hashtable hash=new Hashtable();
hash.put("page 1",new ArrayList());
hash.put("page 2",new ArrayList());
hash.put("page 3",new ArrayList());
the code i am using in java is
if(hash.containsKey(new String("page 2"))
ArrayList value=hash.get(new String("page 2"))
i want to this will be implemented through the tag library.
----------------------------------------
| page 1 | questions in a arraylist |
----------------------------------------
| page 2 | questions in a arraylist |
-----------------------------------------
| page 3 |questions in a arraylist |
----------------------------------------
this is a key-value pare.
i think now you under stand the question.
i am already reterive this through scriplets and implement, but now i want
this through the tag library.
is any tag provided for this type of functionality.
Regards
Shashi BHushan
