i believe Predicate is in camel-core, and OGNLExpression is in camel-ognl, SQLExpression is in camel-josql, and SpelExpression is in camel-spring.
I'm not sure about JXPath, but in general you can look at the online javadocs [1] and see component/artifact name in the URL. the wiki [1] will also usually have the maven dependency block for each component, which names the artifact (i.e., the jar). sometimes i also use grepcode [3] to search for these things.
