Hi,

I have a app which runs on spring boot, and using kie-ci to execute the rules. Is there a way for me to use kie-wb in sprinboot to externalize the rules, so I can change the rules outside the app without re-deploying the code?

I tried with kie-server-spring-boot-starter:7.6.0 dependency, but couldn't make the kie-wb work. Is there any other option for UI to host my rules?

Thanks,
Sai

For kie-server-spring-boot-starter, how did you override 'DefaultWebSecurityConfig'?

I used below, but doesn't seem to be working. Am trying to do without keyCloak.
@Configuration("kieServerSecurity")
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter

it all depends how it’s deployed:
- manual deployment to WildFly is then based on the war file name - usually http://localhost:8080/kie-wb
- installed via jbpm installer it will be http://localhost:8080/jbpm-console

Hi Maciej,

Thanks for you support.
kie-drools-wb-7.7.0.Final-wildfly11.war is only compatible with wildfly 11 ?

thanks,

it was tested with WildFly 11 though it might work on 11 and later versions but was not tested. There are less chances that it will work on WildFly 10 …

I have this error when I start standalone.bat with kie-drools-wb-7.7.0 and wildfly 13.0.0.beta.1

When I try to access to http://localhost:8080/kie-web nothing happened, just the

there is no outofmemory error when I started the server wildfly I have got this

}


I have only deployed kie-drools-wb-7.7.0.war on wildfly and not kie-server.war.
It's possible to use KieServer from SpringBoot to use  KIE-WORKBENCH or it's important to have both kie-server and kie-workbench wars on wildfly server ?

Thanks a lot ,

yes, you can have KIE Server from spring boot which will be managed by workbench see the starters and samples we have https://github.com/kiegroup/droolsjbpm-integration/tree/master/kie-spring-boot/kie-spring-boot-samples

I have got this error on my spring boot project, what's wrong with my configuration ? 
Thanks,

2018-05-28 11:08 GMT+02:00 Younes Krifa <younes...@perfectstay.com>:
ok thanks !

so if I want to use spring boot project with keycloak authentication and kie server managed by workbench I must follow this step : (correct me if I am wrong)

1. download keycloak and start keycloak on port 8080 ( standalone.bat command )

2. start springboot server on port 8090 with the following properties
kieserver.restContextPath=/rest
kieserver.serverid=springboot
kieserver.location=http://${server.address}:${server.port}${kieserver.restContextPath}/server
kieserver.controllers=http://localhost:8090/kie-wb/rest/controller

keycloak.auth-server-url=http://localhost:8080/auth
3. set   kie-drools-wb-7.7.0.Final-wildfly11.war on wildfly11/deployments directory  and start wildfly 

question1: can I set  kie-drools-wb-7.7.0.Final-wildfly11.war on keycloak/deployments directory or there should be independant ? °
question2 : if I launch keycloak and kie-drools-wb on wiIdfly separatly I must change port name of one configuration ?


4. last step if I have want workbench managed by  KIE SERVER from spring boot project I must change this propertie to use the correct endpoint generated by kie-drools-wb-7.7.0.Final-wildfly11.war on wildfly11 ? 
or I must change configuration on wildfly11 server ?
kieserver.controllers=http://localhost:8090/kie-wb/rest/controller

Thanks a lot for you support 
I am not familiar with redhat eco-system and we want to use jbpmn 7 for production.
