to Drools Setup

I have been struggling for days to register Kie Execution Server to Drools Workbench. Both war files are version 6.5.0.Final and deployed as exploded directory on same weblogic12.2.1.2 instance. Workbench itself works just fine; I can access http://localhost:7001/drools-wb to edit example mortgages project without problem. I can also invoke empty Kie Execution Server restful endpoint fine, e.g., http://localhost:7001/kie-server/services/rest/server. The problem is the Kie Execution Server is NOT registered to Workbench server. I tried a similar setup on Wildfly 10, and it works fine, but stuck on weblogic with console error showing response code 404. If I try to deploy container from Workbench to Kie Execution Server, there is no server connection at all.

On the server console log, there is response code 404 error every 10 seconds:

Workbench and Kie Server run on the same weblogic admin server instance. I have set up data source, jms etc according to Red Hat Jboss BRMS Oracle Weblogic Installation and Configuration Guide. Here are the command parameters starting WLS:

I might be mistaken but drools-wb is for development purpose only and for regular use you should use kie-drools-wb

You are not mistaken Maciej.

drools-wb is not available in our release distributions (only kie-wb and kie-drools-wb). We do not build a WAR for drools-wb either.

Thanks for your response. I got Drools workbench and Kie Execution server from Drools.org download site. The terms are confusing, kie-wb, kie-drools-wb, drools-wb etc. Drools workbench I mentioned is kie-drools-wb.

https://download.jboss.org/drools/release/6.5.0.Final/kie-drools-wb-6.5.0.Final-weblogic12.war

After more digging, I think the response 404 error is due to the old jersey 1.x version in workbench(kie-drools-wb) weblogic distribution running on Weblogic 12.2.1.2. Weblogic 12.2.1.2 supports Jersey 2. Should I update the drools workbench to Jersey 2.x or stay with Jersey 1.x for restful webservice for kie-drools-wb ? Your recommendation is appreciated. kie-drools-wb for Wildfly distribution uses Jersey 2.x, and it works perfectly.

Here is configuration snippet for Jersey 1.x in web.xml of kie-drools-wb-6.5.0.Final-weblogic12.war:

<servlet-name>RestServlet</servlet-name>

<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

<init-param>

<param-name>com.sun.jersey.spi.container.ResourceFilters</param-name>

<param-value>com.sun.jersey.api.container.filter.RolesAllowedResourceFilterFactory</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>RestServlet</servlet-name>

<url-pattern>/rest/*</url-pattern>

</servlet-mapping>

there should be some errors saying why the REST endpoint didn’t start. Can you check server log?

In addition you can check if any other REST endpoint works in kie-drools-wb app for instance http://localhost:7001/drools-wb/rest/repositories

Hello Maciej Swidersk,

along with kie workbench on weblogic i also installed kie-server seperately and getting 403 forbidden on calling http://localhost:5005/kie-server/services/rest/server. am i right or wrong dont know as without kie-server i am only able to use workbench and not able to make endpoint server registeration.

Hi all,

i installed kie-wb on weblogic 12c successfully and able to use all the components but when i am going to register a endpoint for rule deployments its giving error unable to connect endpoint.

Kie wb URL:- localhost:5005/droolsWB.

endpoint url ===?? no idea

i tried for :-localhost:5005/droolsWB/kie-server/services/rest/server.

after that i installed kie-server-6.2.0.final-ee7.war on same weblogic12c as kie-server(name)

when i am trying to hit "localhost:5005/kie-server/services/rest/server." it is giving 403 forbidden( i tried a lot to resolve issue but no luck)
