Wildfly + Eclipse Deployment Scanners

Question

I'm completely new to working with servers in general and I am trying to set up some software for a class that is starting next week. I keep running into this problem while trying to get Wildfly to work through Eclipse. I go to run the server and every time, no matter what version I choose, I always get this same error message:

An internal error occurred during: "Updating Deployment Scanners for Server: WildFly 24+". Could not initialize class org.wildfly.security.auth.client.DefaultAuthenticationContextProvider

Here is the console log as well

I feel like I'm probably just missing something very basic here; as I said I am very new to this. The server does technically run, but without the Scanners I can't access any of the project directories.

Thanks so much for your help!

Answer 1

I also faced the problem while upgrading Java from 11 to 17. Researching for the root cause led me to a discussion on google. It looks like some access restriction has changed since Java 11 and the problem can be solved by adding

--add-opens=java.base/java.security=ALL-UNNAMED

to the -vmargs section in eclipse.ini.

Answer 2

It looks like this may be due to running Java 1.8 as your default Java install (i.e. Java 1.8 is what is first in your PATH environment variable).

I was able to resolve this issue by using the following installs

• jdk-11.0.11_windows-x64_bin.zip
• wildfly-24.0.1.Final.zip
• eclipse-jee-2021-03-R-win32-x86_64.zip

And then adding the install of jdk-11.011 to the beginning of my Path variable. I was then able to reproduce the problem by adding a Java 1.8 version to my path variable. For example, the configuration below gives the error. Removing the first line resolves the error.

This gives the error

This Works!!!

To ensure you are using Java 11, open a cmd window and type java -version
