How best to modernize the 2002-era J2EE app?

I have this friend....


I have this friend who works on a java ee application (j2ee) application started in the early 2000's. Currently they add a feature here and there, but have a large codebase. Over the years the team has shrunk by 70%.


[Yes, the "i have this friend is". It's me, attempting to humorously inject teenage high-school counselor shame into the mix]


Java, Vintage 2002


The application uses EJB 2.1, struts 1.x, DAO's etc with straight jdbc calls (mixture of stored procedures and prepared statements). No ORM. For caching they use a mixture of OpenSymphony OSCache and a home-grown cache layer.

J2EE tutorial (Learn J2EE in 21 Days, Sams)
Programming Languages

Hello everyone,
I just bough a book to learn J2EE (Sams Learn J2EE in 21 Days) from ebay.
This book is based on J2EE 1.3, im wondering if its good to read this
book or if it would be better to get a book which is based on J2EE 1.4.
Could anyone tell me ?
Thanks

Upgrade from .Net 2002 to 2002 -- Didnt uninstall 2002 version
Programming Languages

I bought/installed the upgrade to Visual Studio .Net
Professional 2003 (from 2002). I was surprised that it
did not appear to uninstall (or overlay) my old version
(2002) of Visual Studio .Net Professional. There are two
sets of Framework and Visual Studio on both the "conrol
panel/program add-remove" and two sets of menus off
the "start/programs". Id just uninstall the old (as the
new has "2003" off of everything) ... but it just feels
like some kind of a trick. So thought Id see if anyone
else has upgraded (and uninstalled the old) with no
problems ... and to make sure the upgrade is not somehow
