error in JSF deployment with external JAR - jar

Question

I try to add an external JAR library to my JSF project.
My Project structure Looks like this:
XXX (EAR)
XXXWeb
XXXEJB
When I deploy my Project I get the following error from my Wildfly 10.1 console:
15:42:52,338 WARN [org.jboss.modules] (default task-185) Failed to define class de.sqs.topInterface.IAPIException in Module "deployment.sqs-selfservice.ear.sqs-selfserviceWeb.war:main" from Service Module Loader: java.lang.NoClassDefFoundError: Failed to link de/sqs/topInterface/IAPIException (Module "deployment.sqs-selfservice.ear.sqs-selfserviceWeb.war:main" from Service Module Loader): org/omg/CORBA/UserException

#Stateless

public class SQSBean {
public String connect() {
SQS_Connector sc = new SQS_Connector(); // <<-- 23
}
}
At first I tried to add the libraries to EJB. After that I added it to WEB-INF/lib and to EAR/lib. But the error remains the same.
So where and how do I have to include external JAR library files with a common Software API to have access to them in my JSF Webaplication?
If you have an example or how to, it would be very, very nice!
Thank you!
