QUESTION
I have a JAX-RS application deployed in WildFly. The application's endpoints shall be protected by Keycloak with Access Type: bearer-only. This works perfectly fine for WildFly versions up to 24.
Starting from WildFly 25 the Keycloak adapter is deprecated and one should migrate to the new Elytron subsystem. According to this WildFly issue https://issues.redhat.com/browse/WFLY-15485 however the OIDC adapter is not ready yet to work with bearer-only. But it is mentioned that it should still be possible using the Keycloak Wildfly adapter.
Also the latest Keycloak documentation and this thread in Google Groups states this.
So I installed the adapter from this location and ran the installation script:
./bin/jboss-cli.sh --file=bin/adapter-elytron-install-offline.cli -Dserver.config=standalone-full.xml
When deploying the application I get thte following error message:
java.lang.IllegalStateException: The required mechanism 'KEYCLOAK' is not available in mechanisms [BASIC, CLIENT_CERT, DIGEST, FORM] from the HttpAuthenticationFactory
Setup
- WildFly 26 (Jakarta EE 8)
- Keycloak 16.1.1

...ANSWER
Answered 2022-Feb-01 at 07:31I finally got it working without the Keycloak adapter, i.e. using the new built-in Elytron subsystem.

QUESTION
I'm monitoring a WildFly 10.1.0.Final Java process via SNMP port (configuring the com.sun.management.snmp properties) in a Linux box.
The problem is the reported max values for Eden and Survivor Spaces are zero.
...ANSWER
Answered 2022-Mar-11 at 04:46The problem here is that jvmMemPoolMaxSize (OID .1.3.6.1.4.1.42.2.145.3.163.1.1.2.110.1.13) is defined in JVM-MANAGEMENT-MIB as type JvmUnsigned64TC, which seems kind of strange because Java specifically forbids the use of unsigned integer types.
The description for jvmMemPoolMaxSize implies that it's meant to represent the value returned by java.lang.management.MemoryPoolMXBean.getUsage().getMax(). The documentation for that method says "This method returns -1 if the maximum memory size is undefined."
The description of jvmMgmMIB addresses the issue with this explanation:
Where the Java programming language API uses long, or int, the MIB often uses the corresponding unsigned quantity - which is closer to the object semantics.
In those cases, it often happens that the -1 value that might be used by the API to indicate an unknown/unimplemented value cannot be used. Instead the MIB uses the value 0, which stricly speaking cannot be distinguished from a valid value. In many cases however, a running system will have non-zero values, so using 0 instead of -1 to indicate an unknown quantity does not lose any functionality.
I think it's safe to say this is one of the cases where a zero is not valid, so you should take it to mean that there is no defined maximum.

QUESTION
I am trying to upgrade a monolith application from Wildfly 23 to Wildfly 26.
Originally the application used a dummy configuration of "jaspitest" in the standalone.xml
Old Config for security
...ANSWER
Answered 2022-Feb-14 at 14:29The setup seems somewhat confused. The LoginBacking should not directly call the IdentityStore. Instead, a backing bean should call SecurityContext. The SecurityContext then triggers authentication causing the HttpAuthenticationMechanism to be called, which then, if needed, calls the IdentityStore.
The Soteria project contains a test that demonstrates this for JSF/Faces:

I'm running Keycloak 15.0.2 in docker (jboss/keycloak:15.0.2) and use Identity Brokering with an external OpenId Connect Identity Provider
When a login is initialized on keycloak the browser is redirected to the external IDP. After authenticated there the browser is redirected to keycloaks broker endpoint /broker/oidc/endpoint?code=xxx
But then Keycloak throws a Exception caused by
Caused by: java.security.NoSuchAlgorithmException: HMACSHA256 Signature not available
Has someone an idea why this is happening? Should this HMACSHA256 algorithm not already be part of the JRE in the docker-container?

Answered 2022-Feb-09 at 16:03I had the same issue and could solve it by changing the "Client Assertion Signature Algorithm" from HS256 to RS256 for the identity provider in Keycloak.

My Webapp is deployed in Wildfly 25.0.1.Final and is secured using OpenID Connect (OIDC). WildFly 25 enables you to secure deployments using OpenID Connect (OIDC) without installing a Keycloak client adapter.
It is configured like this:

QUESTION
I'm trying to deploy a HA Keycloak cluster (2 nodes) on Kubernetes (GKE). So far the cluster nodes (pods) are failing to discover each other in all the cases as of what I deduced from the logs. Where the pods initiate and the service is up but they fail to see other nodes.
Components
- PostgreSQL DB deployment with a clusterIP service on the default port.
- Keycloak Deployment of 2 nodes with the needed ports container ports 8080, 8443, a relevant clusterIP, and a service of type LoadBalancer to expose the service to the internet
Logs Snippet:
...ANSWER
Answered 2022-Feb-05 at 13:58The way KUBE_PING works is similar to running kubectl get pods inside one Keycloak pod to find the other Keycloak pods' IPs and then trying to connect to them one by one. Except Keycloak does that by querying the Kubernetes API directly instead of running kubectl.
To do that, it needs credentials to query the API, basically an access token.
You can pass your token directly, if you have it, but its not very secure and not very convenient (you can check other options and behavior here).
Kubernetes have a very convenient way to inject a token to be used by a pod (or a software running inside that pod) to query the API. Check the documentation for a deeper look.
The mechanism is to create a service account, give it permissions to call the API using a RoleBinding and set that account in the pod configuration.
That works by mounting the token as a file at a known location, hardcoded and expected by all Kubernetes clients. When the client wants to call the API it looks for a token at that location.
Although not very convenient, you may be in the even more inconvenient situation of lacking permissions to create RoleBindings (somewhat common in more strict environments).
You can then ask an admin to create the service account and RoleBinding for you or just (very unsecurely) pass you own user's token (if you are capable of doing a kubectl get pod on Keycloak's namespace you have the permissions) via SA_TOKEN_FILE environment variable.
Create the file using a secret or configmap, mount it to the pod and set SA_TOKEN_FILE to that file location. Note that this method is specific to Keycloak.
If you do have permissions to create service accounts and RoleBindings in the cluster:

QUESTION
I am developing an application targeting a Java EE 8 application server (JBoss/Wildfly).
However, one of the dependencies (elasticsearch api) is already using jakarta.json.* classes which results in a ClassCastException at runtime:
java.lang.ClassCastException: org.glassfish.json.JsonProviderImpl cannot be cast to jakarta.json.spi.JsonProvider
That is because the org.classfish.json.JsonProviderImpl in my classpath (org.classfish:javax.json:1.1.4) is still using javax.json classes.
However, as both org.glassfish:jakarta.json and org.classfish:javax.json define the same class org.classfish.json.JsonProviderImpl (one using the javax.json.* classes and one using the jakarta.json.* classes...), I am unable to simply include both maven artifacts.
The implementation of JsonProviderImpl (in both artifacts!) basically returns the following by default:
...ANSWER
Answered 2021-Dec-10 at 15:05One workaround seems to be to use the maven shade plugin to basically "rename" the package org.glassfish.json in the "new" org.glassfish:jakarta.json to jakarta.org.glassfish.json:

My goal is to allow several BUT NOT ALL origins for http requests to my Wildfly 10. I have searched StackOverflow and haven't found anything so far on this topic. People all over the Internet suggest using a wildcard, however this could effectively be a security flaw. Yes, a wildcard for Access-Control-Allow-Origin does work, but I don't want to allow just any origin. I have tried this standalone.xml part for undertow subsystem (unsuccessfully):
