osx - my eclipse stopped working today -

-

today running problems eclipse, every time closed project window popped saying "error saving workspace" , complaining apache xerces.

i decided download fresh install, , won't start. tried many variants (classic, javase, c++), hoping there distribution issues, nothing worked. eclipse starts saying "an error has occurred, see configurationlog ..."

any idea? there cached files in system might have become corrupted? tried doing "find / | grep eclipse" found nothing interesting.

thanks lot help, i'm quite in trouble without it

regards,

nicola montecchio

p.s. tried 32 bit jvm nothing changed

[edit] here relevant bits of log produced when starting:

!entry org.eclipse.osgi 4 0 2010-07-23 21:35:16.835 !message unexpected runtime error has occurred. !stack 0 javax.xml.parsers.factoryconfigurationerror: provider org.apache.xerces.jaxp.saxparserfactoryimpl not found

and several other related xml ...

sounds current workspace severely broken. create new workspace , import projects old locations (file -> import), , see if helps.
