[keycloak-user] Linkage Errors

Wed Jun 25 03:19:28 EDT 2014

Hi,

I think the problem is in the fact that you are using:
compile 'org.keycloak:keycloak-core:1.0-beta-3'

because if you do this, then keycloak-core.jar (and maybe some other 
files) is copied into your WAR under WEB-INF/lib, which is not good. You 
shouldn't have keycloak and httpcomponent jars inside WEB-INF/lib, but 
instead all your dependencies should be specified in 
WEB-INF/jboss-deployment-structure.xml to reference dependencies 
provided by Application server. Keycloak modules should be added as 
modules into JBoss AS as specified in documentation.

I would suggest to look at our example applications here 
https://github.com/keycloak/keycloak/tree/master/examples/demo-template/ 
(they are also part of distribution). For example if you look at 
customer-app application, you can notice that it has all dependencies as 
'provided' in pom.xml : 
https://github.com/keycloak/keycloak/blob/master/examples/demo-template/customer-app/pom.xml#L32 
and in jboss-deployment-structure it has dependency on httpcomponents, 
which is something you will need as well (note ClassNotFoundException in 
your stacktrace): 
https://github.com/keycloak/keycloak/blob/master/examples/demo-template/customer-app/src/main/webapp/WEB-INF/jboss-deployment-structure.xml#L6 
. Keycloak dependencies (like keycloak-core) don't need to be specified 
in jboss-deployment-structure.xml as long as you install keycloak 
modules and add jboss subsystem into standalone.xml as described in 
Keycloak docs and in README of examples.

Good luck,
Marek
