First off, I'd say try to go with jdk5. There is some discussion about
dropping 1.4 support in S2.1 and it looks like it could be a strong
possibility.
The exception you're seeing indicates the JDK is 1.4 and your trying to use
the 1.5 distribution. I've got no idea what RAD-6 or RAD-7 is, but from the
error I'd double check RAD-7 is using JDK 5 and you've not got something
configured to run it under a 1.4 JVM.

Subject: Struts 2 with RAD 6
Hi,
I am trying to figure out how could I use Strus-2 with RAD-6 which has Jdk
1.4.
I even tried to run the mail reader application on RAD -7 which has jdk
1.5 with JRE 5.
Could someone please help me running the sample code on RAD-6. I was also
not able to figure out how I could use jdk 1.5 on RAD-6.
I am aware that there is a build for jdk1.4 but does it have some
functional or performance difference from the Struts-2 build for jdk 1.5
I am getting an exception
