Exception thrown but nothing in message.log

[Bill Walton]

I'm getting a exception thrown when trying to print to a shared printer from NetBeans.  I realize that the root problem is NetBeans, not Ubuntu.  The reason I'm posting here is that the error message says I should see something in messages.log.  

I did have some content in messages.log but wanted to get a clean, one attempt -> one error, log to attach to the issue I filed at netbeans.org.  So removed messages.log and then created an empty version with vi.  Now when I attempt to print from NB I get the same exception but nothing is being written to messages.log.  The permissions on the file I created are '-rw-r--r--'.  I tried 'chmod +w messages.log' but the permissions are not changed.  Interestingly (to my newbie brain, anyway) 'chmod +x messages.log' _did_ change the permissions.  

So my main question is...  did I screw something up with how I approached messages.log?  Or is this all a NB issue?

And secondly, why can I add execute permissions but not write permissions?

TIA,
Bill
