Unable to get activiti running in tomcat 7/8

[sramanat]

Guys,

I am new to Activiti, so please bear with me here.

I am using the following

System - Windows 10 Home (64 bit 1607, OS Build - 14393.447)
Java - 1.8.0_111
Activiti - 5.0.22
Tomcat - 7.0.70 (for testing this out), 8.0.36 (for my other webapps usually)

With this setup, I restarted tomcat (both 7 and 😎 multiple times, but when I try to access localhost:8080/activiti-explorer from my browser I get HTTP 404 error. I have copied activiti-explorer.war to the webapps folder of tomcat, but that does not help. My other war files work well under tomcat, but for activiti I keep getting 404. (HTTP Status 404 - /activiti-explorer)

I've setup JAVA_HOME appropriately. Am I missing anything here?

PS - The same setup was tried on an EC2 machine running ubuntu (4.4.0-38-generic #57-Ubuntu SMP Tue Sep 6 15:42:33 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux) with the same results.

Any help would greatly be appreciated.

Thanks,

Hi,
   1. Do you have the Tomcat logs, are you getting any errors?
   2. What DB have you configured; can you test the connection to it?

Hi Vlad,

Thanks for your response.

1. I am attaching catalina logs here. I don't see anything out of the ordinary here. (obviously I'm mistaken). I am also pasting the activiti related lines here -

2. I don't use any DB separately for Activiti and I was hoping that it'd use h2.

Thanks,
Sriram

Hi,

   The logs look fine. I have even tested on my machine with your exact Tomcat version (https://archive.apache.org/dist/tomcat/tomcat-8/v8.0.36/bin/).

   What you can do next:
    - try deploying activiti-explorer on a clean tomcat (no other apps deployed)
    - check how was activity-explorer.war obtained? Downloaded, maven build? Can you share the war for cross-testing?
    - check also Activiti version  6, it has a new UI (http://bpmn20inaction.blogspot.ro/)

Hi Vlad,

I still get 404 error after trying as you suggested by downloading activiti from https://github.com/Activiti/Activiti/releases/download/activiti-5.22.0/activiti-5.22.0.zip

I can't attach the war file because it is 42.453 Megs…

Thanks,
Sriram

Hi Sriram,

   Hmm… have you also tried "clean tomcat installation" plus "fresh download of activiti-explorer.war"?

   If that doesn't work and you get no error messages, then I have no other suggestions
