Kie Execution Server Errors when adding Container

I am looking at using the Kie Execution Server to replace one of our applications. So I installed the 6.4.0 Final execution server in my Wildfly 8.2 server.

Following the directions I did a PUT to add the container to wildfly. It succeeded, but I noticed that there were lots of and lots of errors and warnings in the Wildfly log.

Is this expected? The request did succeed, but why all of these errors? They look bad. If this is what I should expect, then we will not be using the execution server:

I believe that the issue is that the KIE Execution server 6.4.0.Final is not compatible with Wildfly 8.2. The errors indicate that it expects different versions of Modules than are installed in Wildfly

This is most likely caused by your project dependencies. I believe you have declared drools-core or drools-compiler as part of your kjar dependencies and thus kie server is trying to resolve all the classes from the dependencies to see if they can be used for remote invocation. Since drools has dependency on osgi it uses that too and cannot find it, so it prints the warning messages.

To resolve that, make sure all drools, kie, jbpm dependencies are set to scope provided thus it will remove it from scanning process and should not cause these errors to be printed.

Some of that may be true.I'm thinking that whatever benefit we'd get from the Execution Server is will not be worth the extra complexity from builds etc.

I also think that there may be more issues than making KIE dependencies "provided"

We don't use this, but it as well as a number of injection related code comes up with errors.

There was a dependency that I missed. I am now down to some errors around log4j2. I wrote a couple of functions that lets us use log4j2 calls in our rules. This may be the cause. I know log4j2 is not included in Wildfly does the Execution Server use it?

My main use case is to have JavaScript call the server to execute business rules. The only examples I've seen is an AngularJS demo that calls the server to run jBPM processes, are there examples where JavaScript calls to fire rules as a normal Rules Session?

Cool. I happy to be here and see someone faced this problem. could you please share the dependency(if its Kjar related) which you had missed? Thanks in advance!

I am seeing the below error when I add the scope to 'provided' for all KIE dependencies. Any help would be greatly appreciated.
