Given that GNU [1] list the Apache licenses as "GPL-Incompatible, Free 
Software Licenses", I've always interpreted that to mean that you can't link 
to (i.e. make use of) Apache-licensed libraries (jars) in a project that 
you're releasing under the GPL.  They don't appear to have an equivalent 
list for LGPL compatibility, unfortunately.
I do recall that previous discussions on this list have stated that 
Apache-hosted projects aren't allowed to [L]GPL libraries in their CVS 

If I've got this all backwards, someone please let me know; I've a project 
of my own [2] that I would have licensed under GPL if not for the fact that 
I made use of libraries that were released under Apache and BSD licenses.  
Instead I went for LGPL on the grounds that I can find a lot of other LGPL'd 
projects that use the same libraries, so it looks like that's okay...
