I have a scenario with 1000 of classes and I am not able to debug the scenarios to identify the code flows.


I want to add loggers in each and every method starting point of all the classes.


It takes more time to write loggers code manually in all the classes.


What is the alternative approach which writes loggers when it enters into each method in any of the classes?.

I have arraylist which is already set in controller side.

I need to update the same list(removing few elements in the list) in jsp based on few conditions like, the selected values in dropdown kind off.

How to update the list in jsp?. Is there any way to handle this using JSTL?.

Instead of using scriptlets, can i do this?

Have you tried it?. Is that working?..

You have an option to add it as Runnablejar and choose the main class(to be execute) as part of your application before creating jar.
