Subject Re: deploying struts2 at godaddy dedicated server - general question
Date Sun, 21 Jun 2009 19:23:09 GMT
Thanks! Everyone's suggestions are correct. The versions provided by godaddy
are:
ROOT/usr/java/jdk1.5.0_17, and
ROOT/usr/java/tomcat-5.5

Currently in dev I am using later versions for both. Wes, I think you are
right, I'd need to at least match at those versions mentioned above on my
local development. But, even after matching, do I still need integration
between apache and tomcat on godaddy side, or matching versions between dev
and prod take care of this?

Dave, that is correct, when starting the project on eclipse I am prompted to
select a dynamic web module version (2.2, 2.3, 2.4, 2.5) I am reading online
about the J2EE Web module specification, but can I quickly ask what is the
meaning of a web module? Is it possible to convert backwards between module
versions? Is it eclipse-related, tomcat-related or does it indicate which
servlet/jsp spec I can use?

Apparently older versions of tomcat support only earlier web module
versions. Other than that, are there other reasons of choosing one web
module version over another?

Thanks again for your responses.
