[edit] Script to find out in which jar a class is:

find ~/.m2/repository/ -name *.jar | while read line ; do unzip -l "$line" | while read line2 ; do echo $line $line2 ; done ; done

(might take a long time, tee it into a cache file for speed ;))

[edit] Servlet deployment

When deploying a WAR, I got the error:

org.springframework.orm.hibernate3.support.OpenSessionInViewFilter cannot be cast to javax.servlet.Filter 

I figured it probably meant I was using incompatible versions of javax.servlet - turns out I was using the DevLoader while I shouldn't.
