Introduction When developing database applications, one of the common requirements is to get the auto generated key back from the database after an insert statement has been executed. Different database vendors offer specific commands that can be used to retrieve auto generated keys, for example in MySQL, executing the following would obtain the last inserted key value. SELECT LAST_INSERT_ID(); Using a GeneratedKeyHolder Spring’s JdbcTemplate uses a GeneratedKeyHolder class to return the last inserted generated key when executing update commands via PreparedStatements.

Introduction Now that Jakarta EE 8 has been released, several runtimes have been updated to support Jakarta EE 8. To showcase this, I’ve written the bare minimum required to deploy a Jakarta EE application onto any Jakarta EE compliant server (in this instance IBM’s Open Liberty. pom.xml The majority of the code is the Maven pom.xml file as shown below. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.developinjava</groupId> <artifactId>simple</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <failOnMissingWebXml>false</failOnMissingWebXml> <maven.

A few days ago, the WldFly Swarm team announced the release of the WildFly Swarm Project Generator. The project generator allows you to select basic project properties (Maven Group ID and Artifact ID) and a list of dependencies for the project before creating a Maven project that can be downloaded and used from within your favorite IDE. The list of dependencies is what makes this generator most useful to me. If you know the name of the dependency to add, or even a few letters from it, you can enter that in the dependencies field and the generator will automatically show the matching dependencies.
