Activiti Explorer

[ggoutham]

Hi Community,

I am using alfresco community 4.2.c. I want to install activiti explorer in alfresco.
For that i have placed the activiti-explorer war file into alfresco/tomcat/webapps folder.
For the first time i have not changed any database files in activiti configuration, the activiti explorer started and showed the login page,
But when i give login credentials showing a login error (obvious because not configured database)

Then i have changed the db.properties file in activiti-explorer with these values
db=postgresql
jdbc.driver=org.postgresql.Driver
jdbc.url=jdbcostgresql://localhost:5432/alfresco
jdbc.username=alfresco
jdbc.password=admin 

When i am starting alfresco it is showing show many errors in log and activiti-explorer is not starting up..

Can anybody please tell me anything iam missing here and is it correct to do like this.

Pleaase help me,,

Regards,
Goutham

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.
