hi Martin,
I here, do not use Spring nor hibernate and indeed need defining a
ServletContextListener implementation that I configure in web.xml that
initializes database connections etc.
In an ideal world:
- You are starting a new web application project from scratch
- You are open to see best practices and learn by example
- You do not have constraints on which technologies to use (e.g. Spring,
Hibernate, Sitemesh, etc)
THEN
Please do yourself a favor an use AppFuse, it will give you a beautiful
Struts 2 application setup out of the box including user-management and
authentication on top of MySQL database. The only thing I can complain
about it though is its usage of sitemesh where I prefer tiles. Maybe
their GenericDao implementations could be polished as well.
Checkout their web site: http://appfuse.org/display/APF/AppFuse+QuickStart
Basically you only need to:
1) Install maven & subversion & MySQL
2) mvn archetype:create -DarchetypeGroupId=org.appfuse.archetypes
-DarchetypeArtifactId=appfuse-basic-struts
-DremoteRepositories=http://static.appfuse.org/releases^
-DarchetypeVersion=2.0.2 -DgroupId=com.mycompany.app -DartifactId=myproject
3) cd myproject and execute "mvn appfuse:full-source"
Then you can start a full forensic analysis on it :) and get the idea
how to structure a beautiful web app :) they even offer a tutorial how
to get you going from that point on.
HTH,
regards,
Giovanni

Hi,
I am new to Struts2 and stumbling immediately.
I want to have an initialization routine in my web app which will connect to a
data base etc. at startup time. This routine needs some parameters (e. g. the
path of a config file to be read). How can I access such external information?
With Servlets I would normally implement a ServletContextListener which would
get its information as an init-param from web.xml.
But for Struts2 there is no <servlet> spec where I could put it.
Writing Struts1 applications I typically utilized a plugin which could read
parameters from struts-config.xml. Maybe this is still possible, but the
Struts2 plugin mechanism seems to be too powerful (or just overwhelming) for me.
What is the preferred way?
Thanks
Martin
