Weblogic portal upgrade from 7.0 to 9.2

[raka sinha]

Hi
I am new to ejb.Actually in my architecture client is BEA weblogic portal 7.0 (using jdk1.3)and ejb is also deployed in BEA weblogic 7.0(jdk1.3).
Now my seniors have decided to upgrade portal to 9.2 which will use jdk1.4.2. but ejb willm be deployed in same 7.0 version.

Can any one tell what problem i am going to face if client in jdk1.4.2 is calling ejb deployed in jdk1.3.

Thanks in advance
