I have a project organized like this:
core
-- /src/main/resources/company/config/spring-config.xml
webapp
-- /WEB-INF/applicationContext.xml
The webapp depends on core.jar
, which is included correctly in WEB-INF/lib
when I deploy.
In web.xml
I have:
<param-value>
/WEB-INF/applicationContext.xml
</param-value>
And in applicationContext.xml
I have:
<import resource="classpath:/company/config/spring-config.xml" />
But when I run, I get this error:
2012-10-04 20:03:39,156 [localhost-startStop-1] springframework.web.context.ContextLoader ERROR: Context initialization failed

When spring-config.xml
is in webapp, everything works fine.
I noticed the leading /
is removed from some of the errors on the stack trace, and I wonder if this has anything to do with it.
Also, I am (unfortunately) using Spring 2.5, if that matters.
For future reference, I figured out the problem after much debugging. It turns out Eclipse was building my "core" library as a jar, but with a web application package layout, so instead of my resource being located here:
/company/config/spring-config.xml
it was located here:
/WEB-INF/company/config/spring-config.xml
which caused the problem. I had checked the jar a few times before, but had never noticed the sneaky "/WEB-INF" hiding in plain sight.
Removing the project and re-importing it into Eclipse (via the Maven pom.xml file) was not enough to fix the problem.
I had to manually delete the Eclipse-specific .project, .classpath, and .settings files. When I did that and re-imported the project everything was fixed.
The moral of the lesson is: ALWAYS check your resource paths when the exception says "File Not Found".
