Aggregate v1.7.1 with Apache Tomcat v 8.5.35,showing "FAIL - Application at context path /ODKAggregate could not be started" in Tomcat Web Application Manager. I need assistance. Here are logs: [catalina.2018-12-14.zip](https://getodk.b-cdn.net/uploads/default/original/2X/3/3dcbd5e688edfe8234b4811980c3b715ba7d0b29.zip) (21.7 KB) [manager.2018-12-14.zip](https://getodk.b-cdn.net/uploads/default/original/2X/3/3876dbb9a1bdac6f5ae583cd446d4d80ba44c77a.zip) (1.9 KB) I will be very thankful to you.

Hi, Please try with Tomcat 7, it should work fine. I tried with Tomcat 8 and it didn't work for me. Thanks, Imran ---

The catalina logs don't provide a ton of hints. If you have other apps in the webapps folder (dhabcbr, dhaprbr, dhaseesbr - Copy, dhaseesbr, ODKAggregate - Copy) remove them for now and see if that improves the situation. If that doesn't help, maybe increase the RAM you have allocated to Tomcat? ---

@tasadduq786 These logs don't really match what you've described above and there are a lot of moving pieces. For example, you said you are using Tomcat 7, but the logs say Tomcat 6. And you said you've removed dhaprbr, but I see that application loading in the logs. We are limited in the help we can provide. What is your high-level goal here? Do you have an existing Aggregate install you are trying to upgrade? ---

I have Aggregate 1.7.1 up and running whith no problems in Debian 9 with OpenJDK and Tomcat 8 as delivered from Debian. So: maybe it may help. if you: 1.) do a fresh install of OpenJDK and Tomcat 8 plus tomcat admin 2.) check, if tomcat works as expected 3.) rerun the Installer to produce a new WAR file 4.) Deploy the WAR with tomcat admin and see, if it works or if it produces any errors as you deploy it. ---

Hi @Raj_Choudhary When you get a chance, please [introduce yourself here](https://forum.getodk.org/t/-/6671). ODK Aggregate is no longer being updated. The last version was released 4 years ago. We recommend using [ODK Central](https://docs.getodk.org/central-intro/) instead.
