Deployment: servlet version differences?

Question

Oracle 8.1.7 (pc, NT4)
iFS 1.1.9 (on the same oracle root)
JDeveloper 3.2 (on another pc)
I've got ever so close to getting my app working on Oracle 8.1.7 with Apache. I'm getting the following error when i try to add new or edit a record:
java.lang.NoSuchMethodError: javax.servlet.ServletRequest: method setAttribute(Ljava/lang/String;Ljava/lang/Object;)V not found
A search in past topics leads me to believe i'm running a version of Servlet specification that does not support 'setAttribute'. When I do a search for servlet.jar i get the following
On the oracle box:
/orant/lib/servlet.jar...45k
/orant/jis/lib/servlet.jar...45k
/orant/ifs1.1/jws/lib/servlet.jar...25k
On the jdeveloper box:
/jdeveloper/lib/servlet.jar...40k
The installation of ifs uses /orant/jis/lib/servlet.jar.
So what's the story? Do I need to upgrade something here or is it a matter of copying a few more files over from the jdeveloper installation.
If I need to update my servlet specification please point me in the right direction.
soooo close, thanks, DC

Answer 1

if you're deploying your jdev 3.2.2 servlet (which uses servlet api 2.1 and 2.2) to the the apache jserv component which only supports servlet api 2.0 -- you will have problems.
you need to deploy these servlets to the oracle servlet engine (ose) component found in the oracle 8i jvm component of the ias 9i or rdbms817 products.
