What is JWt ?

JWt is a Java library for developing web applications. It provides a pure Java component-driven approach to building web applications, and renders either using Ajax or plain HTML.

Unlike JSF, there is no concept of a page and no split between page "views" and reusable "components", making reuse unpractical. Instead, everything is a widget that can be reused in other widgets.

For more information, see the homepage.

Dependencies

The library requires a Servlet 3.0 or 4.0 (javax.servlet namespace), or 6.1 (jakarta.servlet namespace) container. It is able to use asynchronous I/O functionality to improve scalability when using server push features.

If you want to use the PDF rendering support (the WPdfImage and WPdfRenderer classes), then you also need to add PdfJet[http://pdfjet.com/] to your project.

Building

If you are using a Servlet with javax.servlet namespace, it can be as simple as:

make all
ant

If you are using a Servlet with jakarta.servlet namespace, you will need to specify it as a parameter for make. Your make command will then look like this:

make javax=jakarta all

Demos, examples

The homepage contains various examples.

Maven

The ant build file has a separate target to generate maven pom files:

ant mvn

To install the two artifacts in your local repository, do:

mvn install:install-file -Dfile=dist/jwt-4.12.2.jar -DpomFile=jwt-4.12.2.pom
mvn install:install-file -Dfile=dist/jwt-auth-4.12.2.jar -DpomFile=jwt-auth-4.12.2.pom

The corresponding dependency blocks will depends on the Servlet namespace. Here is the what it will look like when using the javax.servlet namespace:

<dependency>
  <groupId>eu.webtoolkit</groupId>
  <artifactId>jwt</artifactId>
  <version>4.12.2</version>
  <classifier>javax</classifier>
</dependency>

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>4.0.4</version>
  <scope>provided</scope>
</dependency>

There are a number of optional dependencies for JWt, needed only depending on what features you use
