> Do exist such things in Jackrabbit as symbolic links or equivalent?

There are multiple options:
- use references [1] (simple but does not scale and doesn't work well
with partial imports/exports [2])
- use weak references (JCR 2.0) [3]
- use string/path properties with links and resolve them manually in
your application
- for files, you can use nt:linkedFile [4] (it uses references)
- shareable nodes (JCR 2.0) [5] [6]

JCR 2.0 will be available with Jackrabbit 2.0 (you can look at the
alpha releases already).
