WO, How to catch an NSRangeException?

[Jon Kleiser]

Excuse me for repeating my question. I have looked carefully in my
WebObjects Info Center, and asked some colleges, but I'm still stuck on
this:

I have obviously not figured out how to catch an NSRangeException. The
following try-catch doesn't seem to work:

   public EOEnterpriseObject trInfoV () {
      EOFetchSpecification trSpec =
         new EOFetchSpecification("TRInfo", null, null);
      NSArray trArr =
         this.defaultEditingContext().objectsWithFetchSpecification(trSpec);
      try {
         return (EOEnterpriseObject)trArr.objectAtIndex(0);   // row 1
      }
      catch (Exception e) {     // NSRangeException
         System.out.println("*** catch NSRangeException: " + e.getMessage());
      }
      return null;      // ???
   }

In my first attempt, I tried "catch (NSRangeException e) {...", but I
couldn't figure out the right com.apple.yellow thing to import (if any). I
have also tried "catch (NSException e)", but I got no reaction there
either. Other kinds of Exceptions (e.g. NullPointerException) work like a
dream. NSRangeException seems to be ... exceptional ;)

Any hints?
