LeBaron,
Your braces don't appear to be matching - the open brace for the try block
(line 59) actually terminates about 18 lines later, not immediately before
the catch block, as it should. You might want to try an editor that has
brace matching capability, such as EditPlus - it can make your life a whole
lot easier.

Subject: Try without catch without try - compile errors
Good Morning Neighbors;
I've been beating my head against this wall for a couple days now, and feel
as though I have exhausted all my other available resources (even the guys
in my own shop won't talk to me anymore.) I've got some code that appears to
be structured fine (I'll include the skeleton at the bottom of the message.)
unfortunately any time I try to run it I get two errors..
'try' without 'catch' or 'finally'. }
'catch' without 'try'. catch (SQLException sql_e)
They're back to back, why for the love of the goddess can't they find each
other? I'm using emacs and when I delete the end bracket just above the
catch statement and put another in it's place, it tells me it matches the
beginning of the try statement.
I thought maybe it was some hidden character that I wasn't seeing that was
messing me up, but I just finished retyping the catch block by hand and
didn't have any success.
Has any one out there run into a similar issue with java in the past? I
could really use the help, I need this code up, and I'm about ready to throw
out the exception handling all together (the programmer gods gasp at my
blasphemy * I repent I repent)
Any how, if you can forgive my neurotic bitterness and offer any advice it
would be greatly appreciated,
Thanks in advance,
Peace,
LeBaron.
Code follows (I apologize in advance for the horrible formatting on this,
it's been copied from unix to windows and from word to notepad, I tried to
clean it up a bit, but I had to make some compromise for readability in a
text wrapping environment. )
