Hi,

1) am i right to create ohter users and tables in activiti DB?

It is possible. On the other hand engine upgrade can be more difficult.
Another possibility is to use expression to get user's manager.

2) How can i get the current user ( should i use serivceTask and implemsts a java code and sql queries or other there is other choice)?

You can use authenticatedUserId in expressions

3) To store the result of this java class should i use resultVariable ?

If the class implements JavaDelegate interface you can create/update any process variable.

4) at last, how can i do the unit test for this ServiceTask to test if i get the true result?

Thank you for your response.
Sorry i have an other question: When i try to test my activiti projetc i get this error:
""couldn't check if tables are already present using metadata.
#Error getting a new connection. Cause: java.sql.ESQLException: No suitable driver found for jdbc.mysql://localhost:3306/activiti"".

All Jars are on the projct ( jdbc.mysql, … etc) , also pom.xml and activiti.cfg.xml are configured.
