I am installing a fresh install of Appian 7.8 using the ACM tool. Everything go

Seems like you are using jdk 1.8* for your fresh 7.8 install. You will need to use jdk 1.7* for Appian 7.8 hotfix B or earlier - forum.appian.com/.../System_Requirements.html

Yeah in this case I have Hotfix C installed as well. Still no luck, same exact error.

Hi mpontius, were you able to start Appian before deploying Hotfix A/B/C? I may try to first deploy Appian without any hotfixes, then once it has started successfully once, deploy the hotfixes afterwards.

I saw that JBoss EAP 6.3.3 is needed for Java 8 support as 6.3.0 does not support it. I can not seem to find a download anywhere for 6.3.3 EAP, so I switched over to use Java 7 and the server fired up.

Hi Matt, to get to EAP 6.3.3, I believe you would need to patch your 6.3.0 install with JBoss EAP 6.3 update 03 from Red Hat. You may need a subscription with Red Hat to download JBoss patches. Patches for latest versions of JBoss EAP 6 are easy to install. For EAP 6.2, it is simply a matter of downloading the cumulative patches contained in a zip file and running a CLI command to apply.
