Play Framework Java 3.0.6 with Ebean, Java 17 and javax.validation

[HenningHeinz]

I have upgraded one of my applications to Play 3.0.6 because it was stated that Play 2.9 does not support jakarta.validation

https://www.playframework.com/documentation/3.0.x/JavaJPA#Bean-Validation-Not-Currently-Supported-in-Play-2.9

Bean Validation Not Currently Supported in Play 2.9

Unfortunately (or as expected as some would say) Play 3.0.6 does have problems with jakarta.validation either.
I have seen some workarounds like
disabling validation mode in persistence.xml, but as I am using Ebean this file does not seem to be in use in my environment.

I also cannot upgrade to Play 3.1.M1 yet, as I also use PlayMorphia (for MongoDB) and Pac4J (Security Framework) which still do cause some headaches.

Currently nearly all post requests cause a console error

play.api.PlayException: Execution exception[[RuntimeException: java.lang.NoClassDefFoundError: jakarta/validation/Validator]]

As the documentation says:

If the absence of Bean Validation poses an issue for your use case, please [inform us]

Any workaround or hint is appreciated. I have to admit my knowledge about Play Framework (Java) is limited.

All of this was/is specificially about Hibernate, but you use ebean.

Ebean is a complete different thing. Which version of ebean are you using?
Ebean offers both, a javax and jakarta implemention, see https://github.com/ebean-orm/ebean/releases/tag/14.9.0
You just need to use the right implementation and I am pretty sure your problem should be solved.

Thank you for your answer.

This is my plugins.sbt

addSbtPlugin("org.playframework" % "sbt-plugin" % "3.0.6")
addSbtPlugin("org.playframework" % "sbt-play-ebean" % "8.3.0")

build.properties

sbt.version=1.10.6

Having a look at the external libs in IntelliJ

io.ebean.ebean 15.1.0

Just took this from the play ebean sample application.
I will try to find documentation on how to use another Ebean version.

Can you please post the full stack trace?

[HenningHeinz]

If I would have to guess it is again play-pac4j that is causing some headaches. I will streamline my project trying to find the root cause.
I am not sure if it makes sense to look into this issue without having access the full project.

Shame on me. In my despair I have added a wrong libraryDependency (spring-context) and forgot later on. All is good now.
