Weblogic 12c - J2EE version

Question

Hello,
I am migrating our J2EE 1.4 apps from Websphere to Weblogic as part of an evaluation.
I am trying to deploy a J2EE 1.4 application into Weblogic 12c. I see strange classloader exceptions. Is this because Oracle 12 c does not support J2EE 1.4?
If yes, can you please help me on the following :
1. Where can I find the Weblogic servers vs supported J2EE versions?
2. What are the version of Weblogic app servers are suitable for J2EE 1.4?
3. I noticed Weblogic 12c has a feature called 'SmartUpgrade'. I am exploring if this will help me anyway.
Thanks in advance,
Rajesh

Hi Lawrence,
I believed backward compatiblity will be present. We don't use weblogic APIs, as this is the first time we are moving to Weblogic. The Error in the sever_0.log file is as follows:
