QUESTION
Migrating a legacy project to Jakarta EE 8 (Maven EAR build on Wildly 26) I am struggling to get the dependancy injection working from my Entities module (EJB packaging) to WAR module, the maven project structure is:

QUESTION
I'm having troubles getting bean validation to work with the following minimalised project consisting only of this three java files plus pom.xml. I'm using Apache TomEE 8.0.10.
LoginMessage.java
...ANSWER
Answered 2022-Mar-15 at 15:29This appears to be a bug in OpenWebBeans or TomEE. So what's happening is the first the actual instance of the bean is managed by JAX-RS, and the second, the bean is managed by the CDI container. In the second case, there needs to be some sort of interceptor the invokes the Bean Validation framework.
I would start a discussion on the mailing list and open a bug on in the JIRA. If you can create a sample project that reproduces the problem it helps the devs out tremendously.
As a workaround, you can @Inject private Validator validator
and if there are any constraint violations returned, throw new ConstraintViolationException(constraintViolations);
.
QUESTION
I have a microservice in Quarkus which implementing CQRS/Event sourcing using AxonIq Framework. I Already made it using Spring boot and everythings it's ok. I would like to migrate it in Quarkus but I have error during maven compilation probably because the Ioc. When CDI try to create the service I think he can inject Axon CommandGateway and QueryGateway.
...ANSWER
Answered 2022-Feb-22 at 08:06I had the same issue, one of the reasons can be that your bean is brought by a dependency and to fix it you need to add an empty beans.xml in main/resources/META-INF in this dependency in order for Quarkus to discover the beans as indicated by the documentation
Relevant extract:
The bean archive is synthesized from:
the application classes,
dependencies that contain a beans.xml descriptor (content is ignored),
dependencies that contain a Jandex index - META-INF/jandex.idx,
dependencies referenced by quarkus.index-dependency in application.properties,
and Quarkus integration code.

I am trying to map all enums
to the same DTO class, I would like to avoid declaring one methood for each enum
type, or using @Mapping
for every enum field.
ANSWER
Answered 2022-Feb-21 at 16:03Did some testing, without the componentModel set to cdi
what you have would generate what you expect.
But with it you need to wildcard the generic typing of the input enum
, after that it should work.
If the EnumUtil would look like this:

Some version information:

- Postgres 9.6
- mybatis-3 CDI
- Postgres Driver 42.2.20 JDBC 4
I'm having a problem that is causing pretty catastrophic behavior in my system. From my debugging I've been able to deduce that an idle transaction appears to be locking a table in my database, causing the application to freeze (certain locks aren't being released). I've been able to stop the freezing my setting timeouts in mybatis but I cannot figure out what is causing the idle transaction in the first place. The good news is that its always the same UPDATE statement that appears to be blocked. However, I can't narrow down what query/trans curring and I'm seeing behavior that I understand.
Here is the query that always seems to lock up (Some names were changed but this query normally works):
...ANSWER
Answered 2022-Feb-15 at 16:39So I discovered what the problem was. The issue really wasn't the database's fault or even the queries that were being used. It turns out that our system was using the same Transaction subsystem for both it our Data Source (Postgres Database) and our JMS messaging system. When a JMS message was sent, it created a transaction and every transactional based action that followed during the life cycle of that tread/transaction would be treated as part of that original transaction. Which includes all of our database calls.....
This explains why a query as simple as insert into a message log was touching all of our relations in the database. The debug queries only showed me the first query/statement sent to the database, not all of the others that were used during the life cycle of the JMS message. There were several ways to fix this but my team opted for the easiest which was preventing the Data Source from using the JBoss provided Transaction Manager.
QUESTION
The following error is given when I try to deploy a simple app (the default one that IntelliJ provides when you create a new Java EE Web App project):
...ANSWER
Answered 2022-Feb-08 at 19:36You are using Java 16 (as shown in the log file) with Maven. In this case, you should use TomEE in version 8.0.9 as this release contains important fixes regarding illegal reflective access (due to the use of Unsafe for proxy creation) in higher versions of Java. You find some details in https://issues.apache.org/jira/browse/TOMEE-3795
It looks like you are using a lower Java version for running your standalone TomEE deployment, which works as it isn't as restrictive as newer Java versions.
Side Note: Java 16 is end-of-life and you should better switch to Java 17.

I would like MapStruct to map every property of my Object, except for one particular one for which I would like to provide a custom mapping.
So far, I implemented the whole mapper myself, but every time I add a new property to my Entity, I forget to update the mapper.

QUESTION
I am a newbie in openmdao. Recently I am trying to implement a dummy wing optimization problem to learn openmdao. I have come up with a weird problem that I wanted to ask about. I am using a bspline to define twist and t/c distribution. The optimization setup is working when I use COBYLA, DifferentialEvolution or DOEdriver as the driver. But when I set SciPy SLSQP, the control points for these splines does not change during iterations. What could be the problem?
Below is the main section where I define the problem...
...ANSWER
Answered 2022-Jan-13 at 17:19Your problem seems to be working with gradient free methods, but not with gradient based one. Hence it's a safe bet that there is a problem with the derivatives.
I'm going to assume that since you're using VSP and AVL, that you're doing finite differences. You likely need to set up different FD settings to get decent derivative approximations. You probably want to use the [appox_totals][1]
method at the top level of your problem.
You will likely need to experiment with larger FD steps sizes and absolute vs relative steps. You can get a visualization of what your intial jacobian looks like using the OpenMDAO scaling report. Your problem doesn't look badly scaled at first glance, but the jacobian visualization in that report might be helpful to you as you test FD step sizes.
QUESTION
I am using Maven 3.6.0 and I have Spring Boot Maven project whose pom file as follows :
...ANSWER
Answered 2021-Dec-14 at 07:28A dependency that has another dependency that has the scope provided
won't lead to that provided
dependency being on the classpath. It probably is there because it is needed for testing or building.
So what you should do is check your end deployment unit (your own jar/war) and check if the jar is there in the lib
directory. If it is something else is managing/including that dependency. (You can use mvn dependency:tree
to figure out which one).
For more information on the Maven scopes, check this. How to include a certain version of Log4j2 (when you are using it) with Spring Boot is described in this Spring.io blog-post.
QUESTION
I'm used to using WildFly for Java/Jakarta EE development and lately I wanted to update a project that is using JAAS for authentication/authorization to the new Jakarta Security API from Jakarta EE 9.1.
I couldn't make it work, so I decided to create the simplest example possible and experiment on different application servers. I took an example from Soteria (as I understand, the reference implementation for Jakarta Security) and created a new Jakarta EE project to deploy on my application servers. The code is available here.
The example includes a very simple identity store for a user reza
with password secret1
:
ANSWER
Answered 2021-Dec-06 at 20:16The WildFly server needs additional configuration:
There is also a script for this on: https://github.com/wildfly/quickstart/tree/main/ee-security#configure-the-server
Why? What is Integrated JASPI?From https://docs.wildfly.org/25/WildFly_Elytron_Security.html#Elytron_and_Java_EE_Security
The EE Security API is built on JASPI. Within JASPI we support two different modes of operation 'integrated', and 'non-integrated'. In integrated mode any identity being established during authentication is expected to exist in the associated security domain. With the EE Security APIs however it is quite likely an alternative store will be in use so configuration the mapping to use 'non-integrated' JASPI allows for identities to be dynamically created as required.
