Ujorm 3.0 is released

Today, the final version of Ujorm 3.0.0 was released, featuring a completely new ORM module for working with JavaBean and Record objects. The goal was a transparent solution with no additional dependencies, supporting type-safe construction of SQL statements.

Ujorm3 requires Java 17 or higher.

Ujorm3 (a new lightweight ORM framework for JavaBeans and Records)

I have prepared a completely new implementation of a lightweight ORM in pure Java that works with JavaBean and Record objects. More details will follow gradually. For now, I am just attaching a link to the project's homepage:

And also a link to the performance tests, which can be used as a reference for your own implementations:

Comments and feedback are welcome :-).

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
