I think that by default the Activiti Explorer application runs with an in-memory h2 database and with example processes, users and groups. So you should be able to login even if you didn't configure Activiti to connect to a database.

Alfresco has Activiti workflow engine already embed, and when Alfresco database is created first time Activiti tables also will be created(you can check them their names starts with 'act_'). So you should disable the Activiti demo setup to prevent it from inserting example processes, users and groups.

Anyway you should get some helpful information about your error from your log file.

Hi,
That's ok. But i want to point my activiti explorer to the alfresco database(postgresql). So that i can have the alfresco users and groups and alfresco workflows. For this thing you have any idea. And using these activiti explorer i want to deploy workflows to alfresco. So that i can use
them in alfresco share and explorer.
If you have any idea regarding this Please share me..

Regards
Goutham

I would also be interested in Activiti + Alfresco integration.

If anyone knows how to do this I'd greatly appreciate it!

I'm also fighting with this problem, but at this moment i can't login into explorer, I'm receiving:

java.lang.NullPointerException
at org.activiti.explorer.ui.login.DefaultLoginHandler.authenticate(DefaultLoginHandler.java:41)

in activiti context XMls I've marked not to generate sample data:


   <property name="processEngine" ref="processEngine" />
   <property name="createDemoUsersAndGroups" value="false" />
        <property name="createDemoProcessDefinitions" value="false" />
        <property name="createDemoModels" value="false" />
‍‍‍‍‍‍

Does anybody have any idea why I cant login?
configuration in db.properties looks like this:

db=postgres
jdbc.driver=org.postgresql.Driver
jdbc.url=jdbcostgresql://localhost:5432/alfresco
jdbc.username=alfresco
jdbc.password=*******

I follow steps here and it work for me :

Before login to explorer, you need to add an admin user in act_id_user. I don't know yet how to link alfresco users to activiti explorer.

Re: Activiti Explorer

dimmumeister — Sun, 27 Apr 2014 15:16:00 GMT

how did you add an admin user in act_id_user ? I did the insert statements :
insert into ACT_ID_GROUP values ('admin', 1, 'System administrator', 'security-role');
insert into ACT_ID_USER values ('admin', 1, 'admin', 'admin', 'admin@localhost', 'admin', '');
insert into ACT_ID_MEMBERSHIP values ('admin', 'admin');
but still could not log into the activiti explorer

This happens when the user who is not admin lands up in the Manage process page of the explorer. None of the links work in it, as he does not have the necessary permission.
