Question about a problem with Derivation and/or Deployment and/or (at the end) a 'NoClassDefFoundError'.
11:23 a.m.
Hello,
I have an problem in the deployment process.
For an higher security context I have to intervene in the original username/password
functionality.
I searched and found the original class
'org.keycloak.authentication.authenticators.browser.UsernamePasswordFormFactory'.
For this mail, I reduced the derivation and manipulation to a minimum and choose the
'secret-example' for deployment.
The derivated factory class get the name
'org.example.derivations.MyUsernamePasswordFormFactory' and would be activated
next to the existing factory in the file
'org.keycloak.examples.authenticator.SecretQuestionAuthenticatorFactory'.
I take the secret-question example because it closest to mine.
But when I deploy the secret-example I get the 'NoClassDefFoundError' (see
below).
I checked the java visibilities (nothing private, protected or final).
The core class reside in the artefactId 'keycloak-services', and the
secret-example pom has a direct dependency entry.
Eclipse (the maven-plugin) is satisfied.
Therefore I found no reason for this exception.
Does anyone have an idea why the *deployment* fails (and which party (Maven, Wildfly or
Keycloak) is not amused)?
Have I missed note something?
Or is a derivation, per se, not desired??
If someone wants to retrace, he/she needs:
* a current 64bit linux with approximately 420MB free space with a directory of your
choice,
* with a running maven environment
* and *without* running wildfly/keycloak system.
Next, you:
* download the demo version in your/this direcory
wget -r
https://downloads.jboss.org/keycloak/3.2.1.Final/keycloak-demo-3.2.1.Fina...
* expand this archive,
tar -xzf keycloak-demo-3.2.1.Final.tar.gz
* save the follow patch (all content between <SecretExamplePatchFile> and
</SecretExamplePatchFile>) file and execute it,
patch -p 0 < NameOfYourSavedPatchFile
* start the example server and save the terminal-log,
keycloak-demo-3.2.1.Final/keycloak/bin/standalone.sh | tee
keycloak-demo-3.2.1.Final.log
* open a new terminal,
* go to the secret example direcory and
cd keycloak-demo-3.2.1.Final/examples/providers/authenticator
* deploy it.
mvn clean install wildfly:deploy
* will see the 'NoClassDefFoundError' exception!
Best regards

Please use keycloak-user mailing list for questions like this (
https://lists.jboss.org/mailman/listinfo/keycloak-user).
It sounds like you should include jboss-deployment-structure.xml in your
example and add dependency on module org.keycloak.keycloak-services, and
possibly some other keycloak modules as well.
