How do I get user info from userID

[vsangal]

I have been researching and found out that this is the best way to current usr info from activiti DB. However, it comes out to be null.

This is my code..

First, I get userID

List<IdentityLink> identityLink = processEngine.getRuntimeService().getIdentityLinksForProcessInstance(processID);

Iterating through this I get userID

if (identityLink != null){

                    for (IdentityLink link : identityLink){
                        userID = link.getUserId();
                        logger.info("getProjectID:  userID ==== is " + userID);
                    }
                }else{
                    logger.info("getProjectID: userID is NULL ");
                }

Now I try to get userinfo, this is null.. Can someone help?

User user = processEngine.getIdentityService().createUserQuery().userId(userID).singleResult();

if (user !=null){    
                    logger.info("FirstName ======= " + user.getFirstName() );

                    logger.info("LastName ======= " + user.getLastName() );

                    logger.info("Email ======= " + user.getEmail() );

                    logger.info("Password  ======= " + user.getPassword() );
                }else{
                    logger.info("user  is ......................... NULL ");
                }

btw,

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

This returns null as well..

List<String> userInfos = processEngine.getIdentityService().getUserInfoKeys(userID);

which version are you using? The Community version or the Enterprise version (Alfresco Process Services)?

[vsangal]

Thanks for the response.

I was developing on community but server is enterprise. I have now switched development to Enterprise and using this command to retrieve userinfo but it still throws  null pointer.. I have following in my file

import com.activiti.service.api.UserService;

@Autowired
 static UserService userService;

User user = userService.findUser(Long.parseLong(userID)); (Getting UserID from IdentityLink code above.

import com.activiti.domain.idm.User;

yeah, if server is enterprise, you need to use the enterprise apis. The identity implementation in Alfresco Process Services is different from what is available in the core engine. Hence it is returning null (as per your original post) when you try to use the core engine apis

I am now using enterprise .. do you know which API can give me userinfo

I saw similar post ..

Are you looking to get a user who is currently logged id? If yes, you can use the following.

com.activiti.domain.idm.User currentUser = SecurityUtils.getCurrentUserObject();  This page has an example - Custom REST endpoints | Alfresco Documentation
