I am using struts 1.0.2, from my action class i am populating
the formbean class, which i used in the jsp to display the data.
When user edit the data in this jps page and press submit then
i pass this data to another action class which uses the same form bean class.
and i redirect it to the same jsp page.
I have some dropdown which i am populating using HashMap.
So when i redirect to this jsp , iam getting this exception.
Also i tried to put the java code in the jsp to check if i am gettting those
Hashmaps ,i am getting the values from the hashmap. But with taglib it's giving
me this error ..
Any help ......

I don't know what happens in Struts or your code. However, this NullPointerException means you are trying to put a null
value into Hashtable.

This happens if you try to put a null in the HttpSession using the setAttribute call.
