This looks like a great project.
I know that it seems like wishful thinking, because Underworld only had about 30 Facebook users the last time that I checked, but I'm trying to get Dimensionex running on Amazon Elastic Beanstalk for the automatic scalability.
I installed and ran Dimensionex on my PC just fine using Tomcat 5 and Java 7. But, Elastic Beanstalk seems to default to Tomcat 6 (32 or 64 bit) or Tomcat 7 (32 or 64 bit). It allows you to upload a .war file for quick deployment. When I attempt to upload and deploy the .war file (which I manually changed from a dimx.zip file by changing the extension) it didn't work. I shouldn't have used Tomcat 7 on the Elastic Beanstalk at first, but I decided to back up and try a few simpler things and to try to get it running on Tomcat 6 on my system first. I got a sample .war file to deploy fine on the Elastic Beanstalk, still using version 7. But, when I tried version 6 and 7 with my dimx.war file on my PC, I get servlet mapping errors. On my PC, Tomcat 6 and 7 create a webapps/dimx/dimx path (two dimx's).
This could be related to some changes that I need to make in the web.xml file. I've seen elsewhere in the forum that Dimensionex can be made to work with Tomcat 6. That seems to be my first little hurdle. Maybe I should use the tutorial on using Netbeans to deploy to Tomcat 6 next.
Any input? Thanks in advance.
