[ OAS 10.1.2.0.2 ] Convert J2EE 1.4 webapp to J2EE 1.3

Question

Hi,
I have a project nicely running under tomcat 5.x and OC4J standalone 10.1.3 ...
Both rely on J2EE 1.4 accroding to what i understood ...
But production environnement is OAS 10.1.2.0.2 ... relying on J2EE 1.3 :(
Deploying the war don't work of course.
So i've made lots of search to find a way ... i have made a few steps forward but i think i need help now :s ...
Correct me if i'm wrong, to deploy J2EE 1.3 web app :
- java classes can be compiled with jdk 1.4.2_x but not 5.0,
- servlet api 2.3 and jsp 1.2 are needed,
- jstl can't be higher than 1.0.x.
So i refactored my code to make it compile with jdk 1.4.2_13.
Regarding servlet api and jsp, i suppose webapp is using the jars provided with OC4J.
Do i need to do anything else ?
I also made little customization of my web.xml :
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

Hi,
Some good news, JAAS was easily configured using web console.
I can navigate through my first forms.
I still got some errors, i think it is related to the way jsp and taglibs are mixed.
It may be different from jsp 2.0 ... i've read some docs about EL expressions ...
I'll deepen this :)
Here is the trace in application.log
