Hi folks,

this is the code I've given in a java class, which is fetching values from a jsp page

infoList.put("compname",request.getParameter("companyname")); // this is the part i'm getting errors

where infoList is a Hashtable object which is declared like "Hashtable infoList = new Hashtable();"

Can someone tell me a solution to solve this ?

Do you not think that showing us the error might be useful?

I hereby bet that the error is a NullPointerException due to the fact that Hashtable does not allow null keys or values.

A wise programmer would verify that the code

is not returning null.

I agree. Here's the link:
