Re: [keycloak-dev] Question about a problem with Derivation and/or Deployment and/or (at the end) a 'NoClassDefFoundError'.

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.Final.tar.gz * 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!
