Hi all, I’m new to zk and I’m trying to convert my old servlet.
Graphic layout apart I have no idea how to perform the following tasks:
- An init phase where I will load files and init variables that will be used by following requests;
- Access those init variables (logs name / the list of loaded files) from my main zk file when this will be called
One more thing …
My old servelt is called from external component via post … how can I do this via zk … I can keep the old CORE servlet just for the main computation with no problem … just to know if I can achieve the same result in a better way.
Many thanks
Kar

Override a init() method is a function to init things in servlet, but if you want to do the same thing in ZK Composer,
you can extend a GenericForwardComposer and init your variables or anything you want. ( Reference ZK-Composer )
ZK will work with Servlet, they control different parts in a web application. You can take any ZK Component as a Object,
composer will help developers easier to use component~~
(sorry for my poor English, wish you can get the point seriously)

There's a suggestion to help you to understand what is ZK-Composer.
The process about view, servlet and composer should be "index.jsp -> Servlet -> Composer", it's not possible
to get variables when you're in a Servlet state. If you want to init a few variables who's used in servlet, you should
write at init() method in servlet, or setAttribute() or setParameter() with a request.
