ClassNotFoundException: org.eclipse.microprofile.config.Config

[ozzi-]

Hi there

I built imixs-jsf-example-5.1.0 with maven as described, and replaced the old 4.0.2 build we had in use. Since microprofile is now used, I had to update WildFly from 13 to the latest stable version 18.0.1. I enabled the microprofile as such

However when deploying the war, I get:

java.lang.ClassNotFoundException: org.eclipse.microprofile.config.Config from [Module \"deployment.imixs-jsf-example.war\" from Service Module Loader

Any ideas what I am missing?

Cheers full log:

Saw in the releases that you mention wildfly16 support, checked with wildfly16, same error

[rsoika]

The error:

.....NoClassDefFoundError: Lorg/eclipse/microprofile/config/Config

indicates that the Microprofile v 2.2 is missing.

please make sure you are using:

• 18.0.0.Final Java EE Full & Web Distribution

or

• 18.0.1.Final Java EE Full & Web Distribution

Wildfly 16 is definitely to old. I will fix this in documentation too.

[rsoika]

In your installation there should be the following directory:

/wildfly/modules/system/layers/base/org/eclipse/microprofile/config/

This will indicate that microprofile is included.

Hi @rsoika
Thank you for your fast response. I am in fact using the Full EE & Web Distribution f 18.0.1. Said path exists on both 16 and 18.0.1: Any idea what I am missing?

[rsoika]

Just to make sure there are no conflicts with stale deployments. Can you undeploy all existing applications and also check the path

/opt/wildfly/standalone/deployments/

This path should be empty before a new deployment.

[ozzi-]

Okay so funny enough, using wildfly-19.0.0.Beta3 it just works. I am slightly confused.

Edit: let me try to undeploy all on 18.0.1 and get back to you

[rsoika]

In deed this is very confusing because microprofile should be available since version 18.0.0 and we are running many productive applications on wildfly 18. very strange......

By the way: do you have a chance to build your application with docker? This makes live much easier.

Hi @rsoika
I can confirm that I cannot get it to run using 18.0.1, undeloyed everything, cleaned the folder and did a fresh deploy. However WildFly 19 works just fine out of the box. Very weird indeed. Unfortunately im not able to use docker in this context - ill continue to use WildFly 19, looking forward to when it looses beta though. Feel free to close this issue - if you want to do further investigation we can, but if im the only one experiencing this we can ignore it ;)

Cheers

Only difference I can see is that WF 18 uses microprofile-config-api-1.3.jar while WF 19 uses microprofile-config-api-1.4.jar

[ozzi-]

Turns out, it was my error trying to reuse standalone.xml of wildfly 13... diffing it seems that wf13 missed "urn:jboss:domain:distributable-web" which causes this weird side effect. sorry for that ... WF18 runs just fine.

[rsoika]

Ah! ok now this explains the situation. Yes the standalone.xml file changes form version to version. For that reason I collect them in the docker config folder: https://github.com/imixs/imixs-jsf-example/tree/master/src/docker/configuration/wildfly

OpenLiberty Server is much better in this situation as you can add your own configuration details in an extra project file.
