Custom jndi object factory in wildfly 8 for CDI - mongodb

Question

I am trying to achieve injecting a jndi resource using CDI for wildfly 8.
For this purpose i want to use a custom jnidfactory as developed in https://github.com/juanlmelo/mongo-jndi-plugin/
The problem is due to my limited knowledge in wildfly, I don't know the following.
1) how to activate/attach this jndifactory in wildfly, ofcourse I can create an object while startup and assign a jndi name to it programmatically , but want to explore custom factory feature of wildfly
2) the best practice to set the uri property needed by the object factory, i assume using System.getProperty inside the factory should suffice , as the DB uri will be different for each installation
once this is achieved I am confident I can get it injected into my classes using cdi.
I have tried my best to look for similar post, but couldn't find any, if you think this is duplicate please point me to the correct one.
Thanks,

If you want add custom JNDI factory to wildfly using https://github.com/juanlmelo/mongo-jndi-plugin/ you need to do few things:
1) You need to change a little bit implementation of https://github.com/juanlmelo/mongo-jndi-plugin/blob/master/src/main/java/com/mongodb/jndi/MongoClientJNDIFactory.java
- line 38 change to:
String mongoURI = (String) environment.get(MONGO_CLIENT_URI);
and comment out or delete lines 39-49
2) then run command mvn clean package and create directory eg.:
wildfly-8.1.0.Final/modules/com/mongodb/jndi/main/
copy there mongo-jndi-plugin-1.0.jar and create there module.xml file with content:
<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="com.mongodb.jndi">
<resources>
<resource-root path="mongo-jndi-plugin-1.0.jar"/>
</resources>
<dependencies>
<module name="com.mongodb.driver"/>
<module name="javax.api"/>
</dependencies>
</module>
3) add mongo driver
-create directory: wildfly-8.1.0.Final/modules/com/mongodb/driver/main
-create there file: module.xml and place there:
<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="com.mongodb.driver">
<resources>
<resource-root path="mongo-java-driver-2.11.0.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
</dependencies>
</module>
-add to this directory mongo-java-driver-2.11.0.jar library
4) add something like this
<subsystem xmlns="urn:jboss:domain:naming:2.0">
<bindings>
<object-factory name="java:global/MongoClient" module="com.mongodb.jndi" class="com.mongodb.jndi.MongoClientJNDIFactory">
<environment>
<property name="mongoClientURI" value="mongodb://username:password#yourdomain.com:27017,username:password#yourdomain.com:27017"/>
</environment>
</object-factory>
</bindings>
<remote-naming/>
</subsystem>
to your domain.xml or standalone.xml
voilà
After this steps you can inject MongoClient into your classes using #Resource annotation (eg. #Resource(lookup = "java:global/MongoClient"
