Sample Java Code I use:
public static AjaxResponse createUser(User newUser) {
Keycloak keycloak = Keycloak.getInstance(
SERVER_URL,
REALM,
USERNAME,
PASSWORD,
CLIENT_ID);
// Get Realm
RealmResource realmResource = keycloak.realm(REALM);
UsersResource userResource = realmResource.users();
// Create User Representation
UserRepresentation user = getUserRepresentation(newUser);
// Create user (requires manage-users role)
try {
System.out.println("Username: {}", userResource.get("USER-ID-HERE").toRepresentation().getUsername());
System.out.println("Count: " + userResource.count());
Response response = userResource.create(user);
System.out.println("Response: " + response.getStatusInfo());
System.out.println("Response: " + response.getStatus());
System.out.println("Response: " + response.getMetadata());
} catch (Exception e) {
System.out.println(ExceptionUtils.getStackTrace(e));
return new AjaxResponse("Fail", false);
}
return new AjaxResponse("Successful User Creation", true);
}
private static UserRepresentation getUserRepresentation(User newUser) {
UserRepresentation user = new UserRepresentation();
user.setEnabled(true);
user.setUsername(newUser.getUsername());
user.setFirstName(newUser.getFirstName());
user.setLastName(newUser.getLastName());
user.setEmail(newUser.getEmail());
CredentialRepresentation credentialRepresentation = new CredentialRepresentation();
credentialRepresentation.setTemporary(true);
credentialRepresentation.setType(CredentialRepresentation.PASSWORD);
credentialRepresentation.setValue(newUser.getUsername());
user.setCredentials(Collections.singletonList(credentialRepresentation));
}
The response I get when I run the code:
Username: USERNAME Correctly Identified here
Count: 98
Response: Conflict
Response: 409
Response: [Connection=keep-alive,Content-Length=46,Content-Type=application/json,Date=Tue, 03 Jul 2018 15:27:58 GMT,Server=WildFly/10,X-Powered-By=Undertow/1]`
Some thoughts: I added the count so to identify if the whole connection works at all. And it seems that the count returned is correct. So I successfully connect to keycloak but something else goes wrong when I try to create a user.

I would much appreciate any help or any guidance. Note Credentials and all variables have been checked, once, twice, thrice, and 10 times again. I've been searching for a complete working example. But most fail to specify the dependencies required and thus my code fails.
Note: I am also using Tomcat-8 and as I am searching deeper into the issue. I see that there are probably some special configurations for Tomcat8. Note that the authentication sign-in sign-out for my web-app already works as expected.
