Hi

It looks like the shared secret that allows Alfresco and Activti to communicate is not in sync in both systems.

Basically you have two places that this secret is configured:
<li>In Actviti - when you add a new repository under the Alfresco Repositories section of the Tenants page. It's the field "Secret"</li>
<li>In Alfresco - by default a value should be already set ("activiti-share-connector-secret" I think), but you can override this by adding a line to your alfresco-global.properties file:</li>


activiti.secret=my-custom-secret
‍‍‍

Make sure the value is the same in both places and you should be fine. See here for more details: http://docs.alfresco.com/activiti/docs/admin-guide/1.3.2/#_activiti_share_connector

If you still hit errors, please provide more information about your setup and the configuration you've done

Regards

Steven

Hi Gary,

Can you have a look at your Tenants page in your Activiti admin console and verify the id of the Alfresco repository you're trying to connect to? Activiti allows you have multiple Alfresco repositories configured against the same Activiti instance, and so it is potentially dealing with more than one set of configuration/credential properties. To do this, it expects Alfresco to send across it's id so that Activiti knows which set of repo config to compare it against.

In Alfresco, the properties you need to set are suffixed by the appropriate id, e.g. activiti.alfrescoRepositoryName=alfresco-1 or activiti.alfrescoRepositoryName=alfresco-2 etc where the 1 & 2 correspond to the id of the repository as seen in the Activiti admin page.

If your repository id is not 1, then you also need to make sure the activiti.alfrescoRepositoryName property is set to the right value in your alfresco-global.properties file.

If you still encounter errors after this, or you already have things set up this way, the best thing to try and do would be to try and capture the details of the traffic being sent between Alfresco and Activiti. The logs show that Alfresco is sending a POST to http://192.168.100.77:8090/activiti-app/app/rest/integration/login which is failing, it might shed some light if you can see what parameters are being sent with the request. If the Alfresco and Activiti apps are on different hosts you can easily capture the traffic using a tool like tcpdump or Wireshark. If they are on the same host its a bit more complex, but you could use something like Charles Proxy or maybe Fiddler to do it.

Regards

Steven

Hi Mahesh,

When you go login to activiti-app as an admin, go to the Identity Management app, click Tenants, and then the Alfresco Repositories tab. It shows a table/list of Alfresco repositories that have been configured and the Id column here is the one you're interested in. See the attached screenshot, the id of my one here being "1"

Hi Steven,

Thanks for the help , I have tried all possible ways still the error persists . Is it recommended to have alfresco one and alfresco activiti installed on different hosts ?

I've set it up locally previously on a single dev box, so no it's not essential and it is possible to get it to work on a single host - the tricky part I found was in getting them talking to the same LDAP and ensuring the LDAP parameters etc all work correctly - this is essential for the proper authentication/authorisation of users between the two systems.
