Hello all,
Newbie question: I'm transitioning from Struts1 to Stripes (hooray!).
I'm using iBATIS for DB access, and in the past I've used the Struts1
plugin architecture to initialize the iBATIS sqlmaps instance on
application startup.
How can I do something similar with Stripes? I suppose the case could
be extended to any sort of sub-package initialization like, say,
first-time Lucene indexing.
I feel like I'm simply missing something silly but perhaps I'm going
about it in a totally un-Stripesy way. Below are my feeble attempts.
Any advice? Thanks!
Ted
p.s. Freddy, maybe this would be a good topic for a Stripes Book blog post.
