JEE | Java -

The application runs in JEE environment. I wish inject a Spy into a bean under test. The Spy object has also some beans inside that should be injected. How can inject mocks of those beans into the Spy?

This is the usecase:

In the new Spring boot 3 Release notes, They tells that this version is going to use Jakarata EE 9 (libs named as jakarta.) instead of JEE (libs named as javax.).

They advise developpeurs to replace imported "javax." to "jakarta." in this article

My question : If i have a spring boot app with javax. libs and jakarta. libs whether the app will work and can be deployed in a tomcat 10 jakarta compatible server ?

Thanks a lot. Impub

so I'm in a new internship position and I was told to modernize a JEE applciation. I've migrated the code in my machine in both .rar , .tar.gz and raw source code , and I sotill get the same problem. so here is the full stack trace of the problem :

In JEE environment it is useful to know, where a particular class is loaded from.

For example I have an instance of org.slf4j.Logger provided by a some black box library. Is it possible to find the responsible classloader? If the class of the instance comes from JDK, Application Server, EAR or Web Application classloader?

I am trying to use storageclass, PersistentVolumeClaim ,PersistentVolume I can run by command promt from local and working fine But when deploying by azure pipeline getting issue "cannot get resource "storageclasses" in API group "storage.k8s.io" at the cluster scope"

I have downloaded the eclipse Oxygen 3 for linux 64 bit from here

When I try to run the eclipse , it shows the error message i.e An Error occurred and a log file path to check ../oxygen-workspace/.metadata/.log.

The log from the log file is as shown below

On a JEE project running on Wildfly 15, I am trying to configure the logs to be in json format. Replicating what I have done dozens of times for some more recent Spring Boot projects, I am adding net.logstash.logback:logstash-logback-encoder:6.6 as a runtimeOnly dependency, as I plan to have a logback.xml config file.

When building my application and running the test, adding this dependency makes some tests fail : some controllers are not able to serialize LocalDateTime anymore.

I see here https://jakarta.ee/compatibility/ the list with all compatible application servers for each JEE version. The question is, are they the minimum compatible versions or do i have to use the exact same version as written in there?

For example, one of written compatible application servers for Jakarta EE 8 is Wildfly 18.0.0. Would it still be compatible with the latest Wildfly (25.0.1) as of today?

I'm trying to get the keycloak quick start applications connected to keycloak and learn how the authorization mechanism works.

I'm following this guide: https://www.keycloak.org/docs/latest/authorization_services/#_getting_started_overview

I've done these steps:

1. Installed Ubuntu 20.
2. sudo apt install openjdk-8-jre-headless
3. sudo apt install openjdk-8-jdk-headless
4. Downloaded and extracted Keycloak-15 on my system.
5. Downloaded and extracted Wildfly-10 on my system.
6. ./bin/standalone.sh -Djboss.socket.binding.port-offset=100 for Keycloak so its running at http://localhost:8180
7. Configured Keycloak adapter for Wildfly instance.
8. ./bin/standalone.sh for Wildfly so its running at http://localhost:8080
9. Copied keycloak.json file obtained from keycloack server to keycloak-quickstarts/app-authz-jee-vanilla/config
10. mvn clean package wildfly:deploy in app-authz-jee-vanilla directory.

Following the guide I mentioned, I'm stuck in the Build, Deploy, and Test Your Application section. I try to build the app-authz-jee-vanilla app but I keep getting this error:
