Hi David, Use a fixed WOPort in your run/debug configuration to avoid this and you get bookmarkable URLs as a bonus too ;-) Kieran On Mar 12, 2009, at 11:45 AM, David Avendasora wrote: Hey all, I have just discovered something that I didn't realize before.

Thinking about it, this could be both a bug and a feature, from Eclipse's point of view... This can cause all sorts of problems.

I had to manually go in and quit the "Java" process in Activity Monitor. However, if you define the port on which the app runs, you can only have one instance running. Other instances can't start up as the port is taken. This is useful also in other situations. For example, I normally run my builds from the cmd line before deploying, because an app can behave differently if you run it from Eclipse (which I do during dev). So, if one version is already running, the other will crash on startup. Thereby, I am 100% sure which app I am connecting to. Talk about spending way too much time looking in my code for a bug.

Re: Eclipse Crashes but WOApp Keeps Running
If you set wolips to always run you app on the same port then you will notice this right away since the app will refuse to run because another app is bound to the port. :) Atli On 3/12/09 3:45 PM, "David Avendasora" wrote: > Hey all, > > I have just discovered something that I didn't realize before.

Eclipse Crashes but WOApp Keeps Running
Hey all, I have just discovered something that I didn't realize before. If you have you have a WO app running inside of Eclipse and Eclipse crashes the WO app keeps running. This can cause all sorts of problems. I ended up with three separate apps running (Eclipse crashed twice) and they were all running the same scheduled task (via Quartz) so not only was it s...l...o...w with lots of unexplained DB activity, I was also getting DB errors on unique-constraints because all three had their own cache of objects and were each creating the same object. I had to manually go in and quit the "Java" process in Activity Monitor. Talk about spending way too much time looking in my code for a bug. I did, however, end up making my app much more resilient to unexpected DB changes. Dave ___ Do not post admin requests to the list. They will be ignored.
