Hi,

I dont think you can get the currently logged in user name in a script task. Reason being, its not dependent on any user to get executed nor it depends on a specific UI framework. But you can always assign the task to users at runtime by having assignee set to ${myuser} and by passing or setting the value of myuser(this is my sample variable. you can always use a different one) at runtime.

> I don't want to use java-code (I don't know where to put the java.class files)
You can bundle up all your java files into a jar and have the jar in the class path.

What do you mean about " have the jar in the class path?"

I'm seeing there's a lot of xxxx.jar files in C:\Activiti\tomcat\lib and in C:\Activiti\java\lib

Am I supposed to put my .jar in one of these directory ?

And what am I supposed to do to get the current logged userId using java ?

Hi,

If you want to assign it to initiatior, try this $INITIATOR
but initiator is not the logged in user. its the one who started the process.

And regarding the jar file. It needs to be in the class path. If you are using tomcat, you can have it in tomcat's lib folder.

Do you know the answer ?

$INITIATOR will store the id of the user who initiated the process.
and in order to get this value you should use:
<code>
var myInitiator = execution.getVariable("$INITIATOR");
</code>

In my opinion you better use a ServiceTask with a JavaDelegate.
and in this case your code will be like that:
<code>
…
User currentUser = SecurityUtils.getCurrentUserObject();
if (currentUser != null){
execution.setVariable("userEmailAddress", currentUser.getEmail());
}
</code>

I put var myInitiator = execution.getVariable("$INITIATOR");
in my script task and this is returning me "(empty)"

sorry,
var initiatorId = execution.getVariable("initiator");
(without $ sign)

Thank you vasile but this is returning me "7" I want the UserNameID but do you know how to transform int 7 to a String UserNameId corresponding to this number ?

Re: How to get current username in javascript using script task?

jbarrez — Tue, 10 May 2016 10:44:01 GMT

that would be the database id. You will need to use the UserService to get the use object.
Or the userInfoBean: https://docs.alfresco.com/activiti/docs/dev-guide/1.4.0/#_user_info_bean_userinfobean

I decided to use JAVA now jbarrez do you know how to transform my int from

String wfUserName = Authentication.getAuthenticatedUserId();
to the current username as a string

I tried to use userInfoBean but this is making an error in eclipse
"userInfoBean cannot be resolved"

I imported import com.activiti.domain.idm.User ;

but what's going wrong ?
