What's new in Ujorm 3.0.3?

A new version 3.0.3 is now available. The SelectQuery class fixes SQL INSERT statement generation when using a third chained relation combined with LEFT JOIN. The negation method for Criterion conditions has been fixed as well. The new version significantly speeds up INSERT operations in cases where retrieving the generated ID key is not required, which has a positive impact especially on PostgreSQL performance tests. The library now automatically loads the logging configuration from the ujorm-config.properties file, so SQL queries are printed to the terminal in JUnit tests without any additional setup.

The changelog is available here.

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:

https://github.com/pponec/ujorm/tree/ujorm3?tab=readme-ov-file#-ujorm3-framework

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.
