Using ibatis in a standalone jar with Spring, and also using spring in web tier

[Rick <ri...@gmail.com>]

This is really more of a Spring question I guess, but I'll ask here first.

I want to have all my persistence classes (services and daos) that use
ibatis to be bundled in a standalone jar that my war (or possibly
multiple wars in an ear) can use. I'm using Spring for
mSqlMapClientDaoSupport and all my tests run fine. The architecture is
such that I have a service class that can call one or several daos in
each method. All of these beans are defined in my
application-context.xml.

In my webapp I'm also using Spring but I having difficulty
understanding how I set up things so that I can I have an isolated
application-context.xml file that loads for my persistence(ibatis) jar
and and another application-context.xml file for my webapp. Right now
I seem to have to delcare all the beans that my persistence jar is
using (services and daos) in my webapp application-xml. Isn't there a
way that I could get the beans defined in my persistence jar
initialized and then somehow used within my webapp classes? I'm
confused how to set this stuff up. Debating about just ditching using
Spring for my persistence jar.

When you say you don't even use DAO anymore what do you mean. You mean
the ibatis or spring dao? you still have the concept of dao objects,
which then I'm assuming you just make calls directly on the
SqlMapClient in those dao methods?

I will have multiple databases unfortunately. I'll post in a bit what
I was planning on doing about it without using Spring and would like
some input if it's a decent approach.

For the record I don't even use DAO anymore.  It's an extra layer of
abstraction that isn't needed unless you know out of the gate that you're
going to have multiple persistence frameworks or databases.

Re: Using ibatis in a standalone jar with Spring, and also using spring in web tier

[Rick <ri...@gmail.com>]

I've looked at guice. I was liking using the SqlMapClientTemplate from spring.

I really don't even need Spring for the ibatis stuff, i was just using
it since I like how easy it was to load different slqMap configs into
different DAOs (since I'm going against different databases within the
app.) I'll look how The Pet Store does things and try that approach I
suppose. Is the Pet Store considered a good practice to follow?

If all you need is DI check out guice.

Sheesh look at this article...
http://springtips.blogspot.com/2007/09/using-shared-context-from-ejbs.html
 it gives me a headache. How the heck can anyone justify using Spring
if you need to do the kind of stuff mentioned in that article. What a
royal pain.

I meant spring-context not application-context, you know the spring
config file:)
