Problem with Tomcat 3.1 and JDK 1.2.2...

[Subha Gowri <su...@indts.com>]

Hi All,

We are working on Tomcat 3.1 with JDK 1.2.2. and deployed all the .jsp pages
in Apache server.
For that we've created a new context in server.xml to take the .jsp pages
from Apache.
It's working fine. But the problem is multiple selection list box in it.

After submitting the page, if I try to get the value from the List box
(multiple) as

String Value[] = request.getParameterValues(name);

it is throwing an exception as,

Note : The same .jsp page is working fine if I use tomcat 3.1 and JDK 1.3. 

If any one find the solution for this problem please let me know.

Thanks in advance,
