The support for Java SE 20, Jakarta EE 10, and MicroProfile 6.0

WebSphere Liberty 22.0.0.6 also adds support for some of the latest versions of Java SE, Jakarta EE, and MicroProfile. These versions introduce new features and enhancements that can improve the development and performance of web applications and microservices.

  • Virtual threads, which enable lightweight concurrency with a simpler programming model.
  • Structured concurrency, which ensures that concurrent tasks are properly nested and terminated.

Jakarta EE 10 is the latest release of Jakarta EE that introduces new features for building modernized, simplified, and lightweight cloud native Java applications. Some of the key features in Jakarta EE 10 are:

  • Support for multipart media type in REST services, which enables sending and receiving multiple parts of data in a single request or response.
  • New functions in Jakarta Persistence queries, such as UUID as a basic type and extensions to the query language and API.
  • Multipart/Form-Data support in Jakarta RESTful Web Services, which allows sending form data with files and other types of data.

  • MicroProfile JWT Authentication 2.1, which aligns with Jakarta RESTful Web Services 3.1 and adds support for OpenID Connect Discovery.

The new option to set a timeout for the server stop command

WebSphere Liberty 22.0.0.6 also introduces a new option to set a timeout for the server stop command. This option allows you to specify how long the server should wait for the application to stop gracefully before forcing it to stop. This can help you to avoid hanging or slow server stops, especially when dealing with complex or resource-intensive applications.

To use this option, you need to add the --timeout flag to the server stop command and specify the timeout value in seconds. For example, to stop the server with a timeout of 10 seconds, you can use the following command:

server stop --timeout=10

If the application does not stop within the specified timeout, the server will force it to stop and log a warning message. You can also use the --force flag to skip the graceful stop and force the application to stop immediately.

The ability to test server connections with the Admin Center Server Config tool

WebSphere Liberty 22.0.0.6 also adds a new feature to test server connections with the Admin Center Server Config tool. This feature allows you to verify that your server can connect to external resources, such as databases, messaging providers, or LDAP servers, using the configuration elements that you have defined in your server.xml file.

To use this feature, you need to access the Admin Center from your browser and navigate to the Server Config tool. Then, you need to select the connection element that you want to test from the left panel and click on the Test Connection button on the right panel. The tool will then attempt to establish a connection using the specified configuration and display the result in a pop-up window.

If the connection is successful, you will see a green check mark and a message indicating that the connection was established. If the connection fails, you will see a red cross mark and a message indicating the reason for the failure. You can then use this information to troubleshoot and fix your connection issues.
