Hello All,

This is my first post. I am using drools from last few months, but it is restricted to using it as an Eclipse IDE plugin with Java to create containers, sessions and executing commands. Thanks to various blogs as well as drools documentation that I could create complex event processing events and execute rules.

Recently my requirement has changed, so now I would like to run same set of rules on KIE-Execution Server. Hence I worked on to setup KIE-Execution Server on Wildfly environment along with KIE Workbench. Thanks to Maciej to providing detailed blog as how to setup server (Accelerate your Business blog at http://mswiderski.blogspot.in/). To create container on server I used APIs such as KieServicesFactory.newRestConfigurationmentioned in this blog but not much luck as there are lot of compilation/runtime errors. Please note that I have included all the required jars to solve compilation errors but still face runtime error.

Hence I thought of taking other approach of deploying container via KIE-Workbench. To test this approach, I took sample “Hello World” project (That is created by default when you create new drools project in eclipse) and created a jar (not executable jar). And this jar is uploaded into artifact repository of KIE-Workbench using option Authoring à Artifact Repository à upload. Once it is uploaded I linked this container to KIE-Execution-Server listed under “Server Management Browser” and started the container.

To check if container is deployed properly I used Advanced REST Client on chrome and executed GET command on http://localhost:8080/kie-server/services/rest/server/containers/Hello (Name of container is Hello) and I receive success message:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<kie-container container-id="Hello" status="FAILED">

</kie-container>

</response>

However when I post fire all rules command via POST I am unable to get any response. So I tried added GET and POST Http methods (javax.ws.rs.GET) in the code but no luck. Now my question is what modifications I need to do to “Hello World” project code so that I can get same response that I see on command prompt when I run this code on Eclipse ?

Environment: Drools 6.3.0.Final on Eclipse, KIE-Execution-Server: 6.3.0.Final

Any pointers in this direction is greatly appreciated.

Thanks and Regards,

Realby

I did not see any response for experts so just wondering if:
- It is wrong or silly question to ask :)
- Below requirement can not be achieved in current version (if anyone thinks so please let me know ASAP as I can stop trying)
- Question is not clear (Sorry for this)

Here you have complete standalone kie server client that can be used from within eclipse: https://github.com/mswiderski/jbpm-examples/tree/master/kie-server-test

when it comes to why the Hello container failed to start you need to take a look at server log to see the error it encountered when starting.
