The ear file deployed on Wildfly and not able to crack the reason. Any clues ?

Tried reinstall ... repackage, maven update/refresh with no luck.

Can you show children pom.xml of EAR and projects using GenericKoinPlusService ? — davidxxx, Aug 17 '16 at 13:11
It begins :) Can you show the pom of the EJB ? It is the culprit in the stacktrace. You should also open your EAR file and check that the `KoinPlusCommons-1.0.jar` file is present in the lib folder — davidxxx, Aug 17 '16 at 13:38
@davidhxxx Added it :) And I just unpacked and checked for the jsr, NOO it is not there :( do I need to place the jar there and then pack it back .. hectic job each time it seems ..please help. — Suresh Atta, Aug 17 '16 at 14:27

Here :

<dependency>
  <groupId>com.koinplus</groupId>  
   <artifactId>KoinPlusCommons</artifactId>  
   <version>1.0</version> 
   <scope>system</scope>
   <systemPath>C://Users/trbrewjars/KoinPlusCommons-1.0.jar</systemPath>
 </dependency>

<dependency>
  <groupId>com.trbrew.common</groupId>  
   <artifactId>TrBrewCommons</artifactId>  
   <version>1.0</version> 
   <scope>system</scope>
   <systemPath>C://Users/trbrewjars/TrendBrewCommons-1.0.jar</systemPath>
 </dependency>

you declare your dependencies with a system scope.
It prevents you from having these dependencies in the resolution of the TrBrewCommerce artifact and so in your final EAR artifact.
If you want that these jars to be included in your EAR, using tricks to keep system scope is not a clean build.
A cleaner way of doing is installing these two jars in your maven repository. After, you could remove the scope system (in this case, scope runtime will be used by default) and the system path in the dependency declaration such as:

<dependency>
  <groupId>com.koinplus</groupId>  
   <artifactId>KoinPlusCommons</artifactId>  
   <version>1.0</version> 
 </dependency>

<dependency>
  <groupId>com.trbrew.common</groupId>  
   <artifactId>TrBrewCommons</artifactId>  
   <version>1.0</version> 
 </dependency>

To install a Maven artifact, you have the install-file goal :

https://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html

It's a pleasure :) When you do no conventional things, Maven may become a nightmare indeed. That's why I intentionally gave you a solution to keep more Maven friendly rather that a solution based on tricks because `system scope` is often a trick ;-) — davidxxx, Aug 17 '16 at 16:30
