WEB4J是一个Java Web应用框架，目标是让使用者建立简单，清晰和优雅的web应用。

WEB4J已经缓慢发展好几年了，最近，已达到“黄金准备期”了。值得考虑推广。

WEB4J的重要特性：
- it's a full stack Java web application framework
- it has a philosophy of deep simplicity and minimalism
- it has the smallest "surface area" of any tool in its class (only 82 classes in its API)
- it has no custom xml files or annotations
- it has no custom tags for form controls (forms are implemented in plain HTML)
- it doesn't use object-relational mapping
- it lets you place your SQL statements in plain text .sql files
- it lets you implement your Model Objects as immutable objects
- it lets you place validation logic in your Model Object (where it belongs)
- if your app is multilingual, it lets your app assist in its own translation
- it lets you use package-by-feature (placing all items related to a single feature in the same directory).
