Welcome to the Ranch

You did realise that was a 4-year old post?

sure, but that shouldn't preclude fixing the mistake. This thread was a number 1 hit on google on this topic, so other people searching for this same thing would no doubt copy the code and find the compile error. i was looking to see if there was a more elegant solution, but ended up doing the simple try/catch. to save time I just copied the code rather than retype, and this small error caused a bit of frustration, because the tool we are using does not have an IDE like eclipse that will tell you in real time where and what the compile error is.

We have a policy of trying to discourage simple replies to old threads, but I seem to get many comments like yours. I am sorry about that; I have actually posted on our moderators' forum asking whether we should alter that policy.

If there is a policy about discouraging old threads, I am not aware of it. And as the mighty tyrant king of javaranch, it seems I should know about something like that.

I think it has been discussed. And I think that some folks have concerns about "waking a zombie" - so that if somebody asks a question about java 1.2 that was resolved in java 1.3 then an old thread might have bad advice. I think there is a little bit of a point to that. But, somebody could reply to that and say "hey, now that time has passed, here's what we do now." That doesn't seem bad.

Or maybe there is a big slice of something I'm overlooking.

I am trying to remember previous discussions, but I thought that the zombie policy also had something to do with the fact that people were just bumping old topics -- by posting and deleting. With jforum, deleting isn't possible, and hence, bumping couldn't be done anonymously anymore. And also, deleting by a mod, seems to unbump the topic.

All in all, the only issue that I have with it, is that it may take some time to get into the mindset, of not worrying about zombies too much.
