Announcing Apache Wicket 10 : build modern web applications with Java!

The Apache Wicket project announces the 10th major release of the open source Java web framework servicing websites and applications across the globe since 2004. Built on top of Java 17, this version of Wicket brings web development into the modern Java world, offering a fundamental tool to write modern and robust web applications.

Use Java to build modern and mantainable web applications

Building robust and manteinable web applications is not a trivial task, especially for Java developers who might feel lost with modern web technologies. With Wicket you can use the rock-solid Java platform to reach this goal without the burden of the complexity that comes with modern JavaScript development stack.

Using Wicket and other familiar tools like Apache Maven you can finally make the most of modern UI frameworks and JavaScript libraries without leaving the Java ecosystem!

Stay up to date with the Java release cycle

Wicket 10 is built on top of Java 17 and is compatible with Java 21. In addtion Wicket takes part in the OpenJDK Quality Outreach to further improve the effort to test compatibility with both the latest OpenJDK release and the Early Access release.

Fast migration with OpenRewrite

Wicket 10 comes with a migration tool based on OpenRewrite to speed up migration from Wicket 9 and avoid repetitive and error-prone manual changes to your code. For more details on this tool see migration guide.

Protect your web apps with Content Security Policy (CSP)

As the number of security threats grows, it's crucial for web applications to adopt the latest security standards and countermeasures. CSP is a modern standard that allows applications to declare approved origins of content (such as JavaScript, CSS, images, etc...) for the browser to load. Constructing a safe and at the same time complete CSP can be challenging. You either risk leaving holes in the defense of your application or you break certain functionality. Protecting against unwanted inline scripts is the most important target to attain. In CSP this is called 'unsafe-inline' and it's the most common cause of cross-site scripting vulnerabilities.

Wicket 10 comes with full support for CSP and does not need any unsafe directives. Wicket will automatically add a nonce to every header contribution and whitelist this nonce. This allows for flexible loading of resources without the need for a complex CSP. Of course it is possible to modify and customize the CSP, add additional directives or disable it entirely. Lookup our documentation for more information.

Download using Apache Maven

With Apache Maven update your dependency to (and don't forget to update any other dependencies on Wicket projects to the same version): 

<dependency>
    <groupId>org.apache.wicket</groupId>
    <artifactId>wicket-core</artifactId>
    <version>10.4.0</version>
</dependency>

Introducing Apache Wicket

Invented in 2004, Wicket is one of the few survivors of the Java serverside web framework wars of the mid 2000's. Wicket is an open source, component oriented, serverside, Java web application framework. With a history of over a decade, it is still going strong and has a solid future ahead. Learn why you should consider Wicket for your next web application.

Just Java & HTML

Leverage what you know about Java or your favourite HTML editor to write Wicket applications. With pure Java code and HTML markup Wicket is the go-to web framework for purists.

Secure by Default

URLs do not expose sensitive information and all component paths are session-relative. Wicket keeps your model private except those parts you explicitly expose.

AJAX Components

Write Ajax applications without having to write a single line of JavaScript code. Wicket's Ajax functionality makes it trivial to update selected parts of a UI, and comes with a great selection of basic Ajax components.

Open Source with Apache License

Since its inception in 2004 Wicket has been an open source project and remains available under one of the most permissive licenses: the Apache Software License.

Maintainable code

Pages and Components in Wicket are real Java objects that support encapsulation, inheritance and events. Create high level components with ease and bundle its stylesheets, JavaScript and other resources into one reusable package.

Internationalized to take on the world

With support of over 25 languages out-of-the-box, Wicket let's you get started in your own language, or a second language with no effort. You can provide alternative languages on the application, page, or even component level.

Multi-tab and window support

No more pain while keeping tabs on multiple tabs and windows. Wicket's automatic state storage ensures that your users can open pages in new tabs and windows without causing problems.

Work with JavaScript and CSS

Global JavaScript libraries and CSS styling mix properly with component local JavaScript and CSS resources. You can use custom component libraries that ship with default JavaScript behaviour and CSS styling, without having to do anything yourself. Creating such self-contained component libraries is as easy as creating a JAR file.

Test your pages and components

With WicketTester you can achieve testing coverage your QA department can only dream of. Test your pages without having to run inside a browser, or start a container. Test your components directly, check their rendered markup tags, attributes and contents with ease.

Injection support

Inject your services into your pages and components with the technology of your choosing: Wicket provides integration with CDI (JSR-305), Spring and Guice.

Jakarta EE integration

If you are using the Jakarta EE, you can leverage JPA, EJBs, Bean Validation and CDI with Wicket's integrations for these specifications.
