J2ee Application Deployed,error connecting to 9i db

Question

Hi,
I am working on a Oracle 10g 9.0.4 AS and a Oracle 9i db, both of which I have just installed on red Hat Linux 2.1 Advanced Server.
I have deployed a j2ee ear file in an OC4J container. The deployment works fine as I get the login page correctly. But it fails to go further than that and gives an error "contact system administrator".The Http Server logs show the following error messages :
[Fri Mar 25 13:07:22 2005] [error] [client 127.0.0.1] [ecid: 172.16.117.169:61745:1111736242948,2] MOD_OC4J_0015: recv() returns 0. There
has no message available to be received and oc4j has gracefully (orderly) closed the connection.

ajp13 message from oc4j.

happened to host: midtier.mastek.com and port: 3303 while receiving the first response from oc4j. This request is recoverable.
I have configured a user in the database with the reqd schema and also a datasource pointing to it and whose jndi name I have specified in the application.
Also, I get an error saying in the OC4J container :
05/03/25 13:02:28 log4j:WARN No appenders could be found for logger (org.apache.struts.util.PropertyMessageResources).
05/03/25 13:02:28 log4j:WARN Please initialize the log4j system properly.
indicating that mebbe the logging hasnt been successfully installed and that's mebbe why I am not getting proper error messages.
I am thinking that there maybe some error in the connection to the 9i database, but cant figure out what.
PLEASE,PLEASE HELLLLPPPPP!!!!
