Can you provide more details? Like exact error type (NullPointerException, ClassCastException), you configuration details (see forum posting details), what were you doing to open the config editor (i.e. doubleclick in the package explorer, beans view, etc)

the problem is that the spring's configuration files does not end with ".xml" extenstion.

Is there a reason you cannot name the file with a .xml extension?
