Ujorm release 2.26

 A new version of the Ujorm library version 2.26 was released today. The changes concern the ujo-web module in particular. The goal of the release was to completely remove the dependency on the servlet-api,

The ujo-web module can therefore be connected both to a project that uses the new servlet API specification 5 (and higher) as well as to a project that uses the older version 4. The module can now also be used to build HTML pages without depending on any version of the servlet , for example for compiling the HTML code of email messages. The module contains a new RContext class (name inspired by Servlet Request Context) that creates a wrapper for the servlet API, the implementation gets resources using Java reflection. I am attaching an example of practical use:

Maven dependency:

<dependency>
    <groupId>org.ujorm</groupId>
    <artifactId>ujo-web</artifactId>
    <version>2.26</version>
</dependency>

The API of the module has undergone some changes, so some parts of the API version 2.26 are not backwards compatible.

Ujorm for Kotlin?

 

A very early prototype of the Kotlin library for modelling filters using a domain object meta-model. Assembled filters work on common POJO objects. The solution was inspired by the Ujorm key-value framework, but this code is completely new. Topical areas of use are:

• dynamic validations
• alerting
• modelling conditions for ORM

A mini Java web application with a size about 5 MB.

I managed to build a web application with a size of only 5.18 MB.
The application contains only a short HTML form with support for simple AJAX events. The project is built on the Javalin framework and a web module from the Ujorm framework.


The source code is freely available on GitHub:

Java HTML Report in a Few Lines of Code

 I’d like to show you a simple table HTML report created with only thirteen lines of source code, written in a single command line using the Java programming language. Let’s pretend the data provision service already exists.

A Simple AJAX Website in Java

During the Covid New Year of 2020, I created a simple prototype website using AJAX, with the goal of moving Java developers away from JavaScript and ideally also text-based HTML templates. I made my original solution a little more general, moved certain parts into the Ujorm framework, and am presenting the result here for your further inspiration.
