Hi,
1. create VO and define Ciew Criteria to query rows based on a bind variable
2. Go to Application Module and select VO, then press Edit button to associate View Criteria
3. Build public method in Application Module Impl class to take user name as an input argument
4. Expose this method on the AM client interface (also shown on the Java category of the AM editor)
5. In the method, use this this.findViewObject("instance name"); to get a hold onto the VO
6. Add the user name to the bind variable using the viewObject.getVariableManager()
7. Execute VO
8. get first row
9. send mail
10. Drag and drop method from the Data Control panel to your login page
11. Use EL to reference the username provided by the user (managed bean reference?)
This should be it
