i need help about java Web application

Question

CMS project with java

Answer 1

+ web storage is related to javascript, not java...
+ user side scripting is related with javascript only...
+ server side scripting could use java, usually with a specific web server framework: probably some can have CMS features, maybe there's some java CMS dedicated frameworks...

You should provide which of them to get accurate help, and be less confuse in your question ^^
