SQL errors with Linux install and how to get around it
Hi,
I've been trying to install the screen scraper server on a new linux server using this tar ball:
http://www.screen-scraper.com/install/professional/lin/ss_pro_lin.tgz
I unzip it to /usr/local/screen-scraper and I "chown" the permissions to a user with full OS permissions. I start up the server and it runs for a little while, but then dumps the trace at the bottom of this post into error.log.
I have also tried updating the server with:
http://www.screen-scraper.com/screen-scraper/updates/2.5.0.14a/update.zip
I also happen to be running jboss 3.2.7 on the same box. Given the error has "hsqldb" in it and I happen to know that jboss runs hsqldb as well, I decided to stop jboss and try starting screen scraper again. It worked!
I started jboss up and it worked fine too. I hope this helps someone else!
cheers

SQL errors with Linux install and how to get around it
Hi Luke,
Thanks, that helps to narrow it down. My guess is that the hsqldb JBoss is running is simply conflicting with screen-scraper's. Fortunately, I think we have a solution that will resolve this. As of a recent pre-release version you can designate the port screen-scraper's database will listen on by adding a property to your "resource/conf/screen-scraper.properties" file like this
DatabasePort=9870
Try setting it to a port you know is free. If that still doesn't do the trick don't hesitate to post a reply.
Best,
Todd

I think I did. I installed it at the recommended /usr/local directory and the INSTALL says if I put it there there's nothing else to do (of course, having said that, it was 4am in the morning and I hadn't slept for 2 days).\
I'm happy to debug if You'd like. I upped trace to DEBUG in the config files but I never got more than the error listed in my original post.
I should point out it's working just fine. I just need to start screen-scraper before my jboss app.

Hi Luke,
In that tarball there is an "INSTALL" file that contains instructions you'll need to follow to properly install screen-scraper. Because it's a manual installation you need to set a few paths manually so that screen-scraper can find its database and such. Did you get a chance to follow the instructions in that file? If so, and it still doesn't work, please feel free to post a reply.
Kind regards,
