I am also using IAS 4 and I have the
same problems. I decided to use
deprecated methods getValue and
setValue - although my JBuilder 3.5 with
Java 1.2.2 compiler returns warnings, it
works.

Michal

Subject: [JSP-INTEREST] HttpSession's
get/setAttribute: Inprise Server 4.0
reports method not found
> Topic: javax.servlet.http.HttpSession
interface - setAttribute and
getAttribute
>
> Development Environment:
> I am running Inprise Server 4.0 (which
accesses it's ias.jar dated 2/16/00) as
> distributed with JBuilder 3.5
Enterprise.
> I have set up JBuilder to access JDK
1.3, j2sdkee 1.2.1's (j2ee.jar dated
> 4/27/00) and jswdk-1.0.1's
(jspengine.jar and servlet.jar)
>
> Two Problem(s):
> This identical code listed below
compiles and runs fine on the J2EE
distributed
> server (based on Tomcat)
> a) could these problems be due to
version differences between the jar
files (IAS
> vs J2EE)?
> b) any suggested methods to attack
this issue (other than drop the Inprise
> server)
> Thanks for your time and
consideration!
>
> 1) In a login servlet, I use
setAttribute (instead of the deprecated
putValue).
> The setAttribute command compiles
under JBuilder without an error.
However,
> when I run this servlet using the
Inprise server (http://localhost...) I
receive
> the following exception:

access a variable "usr" via the

session.getAttribute("usr");
