Hi team,

I have deployed my kie workbench and kie execution server in same environment (jboss-eap-6.4).

I tried to register kie execution server in kie workbench and added one container from workbench.

But I am not able to view the endpoint in the container.

I tried to add below system properties, but it doesnt work .

-Dorg.kie.server.id=wildfly-kieserver
-Dorg.kie.server.location=http://localhost:8080/kie-server/services/rest/server
-Dorg.kie.server.controller=http://localhost:8080/kie-wb/rest/controller

Thanks in advance for your help

check server log for the reason why it did not connect to controller. In addition make sure you have proper authentication configured.

Hello Maciej!

And I'm still having the problem:

WARNING: Exception encountered while syncing with controller at http://localhost:8080/kie-wb/rest/controller/server/tomcat-kieserver error Error while sending PUT request to http://localhost:8080/kie-wb/rest/controller/server/tomcat-kieserver response code 401

I'm running Tomcat, and everything seems to be fine with authentication:

I followed the same tutorial, but can't get what I am doing wrong.

Thank you a lot for a prompt response! It's a shame that I've missed it.
But now I have another problem:

WARNING: Exception encountered while syncing with controller at http://localhost:8080/kie-wb/rest/controller/server/tomcat-kieserver error Error while sending PUT request to http://localhost:8080/kie-wb/rest/controller/server/tomcat-kieserver response code 404

I check endpoint http://localhost:8080/kie-wb/rest/controller/server/tomcat-kieserver - I enter the password, and get 404.
In setenv.bat I have these variables, which I took from the guide:
-Dorg.kie.server.id=tomcat-kieserver

-Dorg.kie.server.location=http://localhost:8080/kie-server/services/rest/server
-Dorg.kie.server.controller=http://localhost:8080/kie-wb/rest/controller

And the .war files have the names kie-server.war and kie-wb.war respectively.

I will be very grateful for help!

I googled here as well about 404 - https://groups.google.com/forum/#!topic/drools-setup/d-DE-U085rQ, but this solution doesn't seem to work, since I use Tomcat.

That means the controller did not start yet. You will see this errors when server is starting but once both kie-wb application is fully deployed and you can access it via http://localhost:8080/kie-wb then controller will be available as well. Double check that workbench starts properly and that you can logon to it.

Maciej, thank you again for your answer!

Strange: workbench works, and here http://localhost:8080/kie-wb I can log in, create a container, and then see it both here and via http://localhost:8080/kie-server/services/rest/server/containers/

But exactly every 10 seconds I get the 404 error.

Probably, it actually works, but every 10 seconds the connection between kie-wb and kie-server is lost?

And should I see anything if I make a request to this endpoint http://localhost:8080/kie-wb/rest/controller/server/tomcat-kieserver ?

Because i saw a chapter here https://docs.jboss.org/jbpm/v6.0/userguide/wb.WorkbenchIntegration.html about some Workbench REST API, but was unable to get anything from it myself using the above mentioned endpoint.

I also tried GET on http://localhost:8080/kie-wb/rest/controller/server/tomcat-kieserver/repositories, but it returned 404 as well.

Check this endpoint:

GET http://localhost:8080/kie-wb/rest/controller/admin/servers

that should print out all connected kie servers. If that endpoint does not exist t means you have wrong version of workbench. Make sure you run 6.3 version for both kie server and workbench. Controller was added to workbench in version 6.3 and thus does not exist in previous releases.

Just for anyone having same issues:

I fixed this problem

"(KieServer-ControllerConnect) Exception encountered while syncing with controller at http://localhost:8330/kie-wb/rest/controller/server/first-kie-server error Connection refused"

by using full qualified host name rather than localhost.

Hi Maciej, I'm having the same problem

WARNING [KieServer-ControllerConnect] org.kie.server.services.impl.controller.DefaultRestControllerImpl.connect Exception encountered while syncing with controller at http://localhost:8888/kie-wb/rest/controller/server/tomcat-kieserver error Error while sending PUT request to http://localhost:8888/kie-wb/rest/controller/server/tomcat-kieserver response code 403

I followed the tutorial and configured correctly the authentication but it does not work

This is my setenv.sh file

This properties are not on your blog but I found somewhere that it could work

-Dorg.kie.server.controller.user=kieserver -Dorg.kie.server.controller.pwd=kieserver1! -Dorg.kie.server.user=kieserver -Dorg.kie.server.pwd=kieserver1!

Thanks

403 means not authorized so make sure your users that are used to connect to controller have roles assigned according to web.xml

the properties are not needed when you rely on defaults - which are exacty the values you have for these properties.

I have followed the same steps to setup kie workbech and kie server on same machine using Tomcat 7 as mentioned in your blog post http://mswiderski.blogspot.in/2015/10/installing-kie-server-and-workbench-on.html

When i start tomcat i am getting the below error.
