Identity management - Overriding Role and capability support

[kethur]

Hi All,

I understand the Activiti's identity service to customize the authentication so it suits individual authentication requirements. 

I have a requirement;
-> A task should be dynamically assigned to the user/group (May be i can get around with ${userName} in the candidate user field).  Please confirm.

-> I need to assign a task to a particular group (dynamic candidate group) but, I want the task to go to only people who have certain roles(eg: "AUTHORISER") and certain capabilities(eg: "GRANT_ACCESS") within the group.

I presume i need to implement this functionality in one of the following classes but which class method i need to add this functionality?  I need to pass 3 parameters, GroupName, Role, Capability to that method.

Many thanks,
Raj

What following classes do you mean? If you want to alter the candidate/claiming behavior, you'll have to alter the UserManage, GroupManager and TaskManager calls related to the calls used in the TaskQueryImpl.candidateUser() and TaskService.claim() commands.

Thanks.  sorry, forgot to add those classes.

NyConnectionParams.java
MyGroupManager.java
MyGroupManagerFactory.java
MyUserManager.java
MyUserManagerFactory.java


So, if i want to override the method - findUserByQueryCriteria in - UserManager class, how would activity Engine calls this method and when would this be called during Engine's the task claiming and completing ?

What if i want to add a new method, how does the engine know to call that method with xyz parameters?


Thanks,
Raj
