<property name="configLocation" value="classpath:com/springinaction/roadrantz/ehcache.xml"/>

Seems IDEA should automatically add "classpath:" if user select a file from classpath.

+ For module without Web facet:

<property name="configLocation" value="[Ctrl + Space when cursor is here]"/>

--> add "classpath:" and display list of package at first level to let user selects one item

+ For module with Web facet:

<property name="configLocation" value="[Ctrl + Space when cursor is here]"/>

--> display list contains "classpath:" and "WEB-INF" to let user select one (currently, after pressing Ctrl + Space, IDEA will add "WEB-INF" automatically)

-->

• if user selects "classpath:", display list of package at first level to let user selects one item
• if user select WEB-INF, work as currently

The general problem is of the linked issues and this one is this: Spring allows both qualified/prefixed as well as unqualified resource references.
When using unqualified references, resolving depends on the type of application context (FileSystemXmlApplicationContext, ClassPathXmlApplicationContext, WebXmlApplicationContext to name some). This is a crucial piece of information that IDEA unfortunately cannot know.

Note that the comments for IDEADEV-18978 describe the problem in more detail (It's marked fixed, but I don't know how the fix works).

This would provide a number of benefits:

• specific resolving/completion (resolving in servlet context path of specified web facet)
• filesets without a linked web facet would resolve unqualified paths in classpath
• IDEA could only suggest "request"/"session"/"globalSession" bean scopes when it makes sense (if matching config is found in linked web facet web.xml)
• Knowing which relation of filesets and web facets would also enable some Spring MVC related features, like resolving of jsp/html link to controllers.
