https://community.appian.com/discussions/f/administration/202/hi-we-are-upgrading-to-6-6-1-soon-and-want-to-make-the-switch-fromHi, We are upgrading to 6.6.1 soon, and want to make the switch from Websphere to JBoss. Currently, we only have JBoss EWS, but the installation guide references EAP. Is EAP a requirement or can we use EWS? Thanks, Stijn...

EWS is just Tomcat and Apache bundled together. We need the application server, either enterprise or community.<div style="clear:both;"></div>https://community.appian.com/thread/473?ContentTypeID=1Thu, 12 Jul 2012 13:49:13 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:5d89daff-fb4a-42e1-b725-9f01478ab52bMichael Tan<a href="https://forum.appian.com/suite/tempo/#entry:e-37322">forum.appian.com/.../</a><br /><br />Myles mentions here that EAP is needed.<div style="clear:both;"></div>https://community.appian.com/thread/471?ContentTypeID=1Thu, 12 Jul 2012 13:28:15 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:04225a02-a13d-4be8-b810-17859a84ff30Michael TanClarification, community edition is what ships with Appian out of the box and is not the same as EWS. EWS and EAP also differ in that EWS also has support for the web server aspect.<br /><br /><a href="http://www.redhat.com/products/jbossenterprisemiddleware/application-platform/">www.redhat.com/.../</a><br /><a href="http://www.redhat.com/products/jbossenterprisemiddleware/web-server/">www.redhat.com/.../</a><br /><br /><div style="clear:both;"></div>https://community.appian.com/thread/470?ContentTypeID=1Thu, 12 Jul 2012 13:11:12 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:b5430b7b-8a4d-4aca-be84-acf3c07d2e91stijnvhDoes that mean that EWS is the same as the community edition that comes with Appian? We have a support contract for EWS, so in that case I think there is no problem in using this version.<div style="clear:both;"></div>https://community.appian.com/thread/468?ContentTypeID=1Thu, 12 Jul 2012 12:38:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:9d8417dd-adfa-46c9-a3c8-ee0ca7ebea1cMichael TanThis response in this entry should be relevant to your question:<br /><br /><a href="https://forum.appian.com/suite/tempo/#entry:e-35541">forum.appian.com/.../</a><br /><br />Short answer: Yes, you can use EWS, but Appian does not patch the community edition, as it is not our software.<div style="clear:both;"></div>
