Cannot load property file as module

[Dennis Soans]

I am attempting to run a Service Provider (Wildfly 26) to execute a Custom Credential Store Class in the first module. This Class then calls another application Class (in a WAR) that attempts to read a Property file in the second module.

The standalone has both the Service Provider jar and the property file in separate modules - one for Jar and one for property file and both modules are global-modules.  Other application jars are in a WAR in the EAR.

        <subsystem xmlns="urn:jboss:domain:ee:6.0">
<global-modules>
<module name="com.myApp" slot="main" />  
<module name="configuration" slot="main" />
</global-modules> 

Example:

Module 1 (Property file):  <WILDLFY_HOME>/modules/configuration/main

<module xmlns="urn:jboss:module:1.1" name="configuration">

    <resources>
        <resource-root path="myapp.properties"/>
    </resources>
</module>

Module 2 (Service Provider) : <WILDLFY_HOME>/modules/system/layers/base/com/myApp/main

<module xmlns="urn:jboss:module:1.1" name="com.myApp">

    <resources>
      <!--   <resource-root path="."/> -->
  <resource-root path="myServiceProvider.jar"/>
    </resources>

Wildfly can find the Service provider with below:

<providers name="credstore"/>

                </aggregate-providers>
                <provider-loader name="credstore" module="com.myApp" class-names="com.myApp.CustomCredentialStoreProvider"/>
            </providers>

Unfortunately it cannot find the property file. I had first tried to place both property file and jar in same module but Wildfly tripped up on reading the property file and complained about being a zip file, so I decided to place them in separate modules.

I am reading the property file in Java as:

instream in = Thread.currentThread().getContextClassLoader().getResourceAsStream("myapp.properties");

I get a NullPointerException here as property file is not located.

I have also made other attempts in defining the modules under the EAR META-INF in jboss-deployment-structure.xml as well as with Dependencies line in application.xml.

So to summarize, why is the jar module (service Provider) located without issue BUT not the property module...????
