Subject Struts 2 with RAD 6
Date Thu, 17 Jan 2008 13:42:04 GMT
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

This is often caused by having a class defined at multiple

include compiling against an older or newer version of the class
