Restcomm jain-slee jackson NoClassDefFoundError: com/fasterxml/jackson/databind/ObjectMapper

Question

Im writing an IDR sender java application using restcomm jain-slee

Im using json decoding as bellow in order to decode the incoming http post request json data.

String postBody = getContentFromStream(event.getRequest().getInputStream());
ObjectMapper objectMapper = new ObjectMapper();

Im using fasterxml jackson for this purpose.

import com.fasterxml.jackson.databind.ObjectMapper;

And I'm deploying this in a WildFly Docker container. When trying to decode the jason I get this error. java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/ObjectMapper

I have added to the jboss-deployment-structure also

<?xml version="1.0" encoding="UTF-8"?>  
<jboss-deployment-structure>  
<deployment>  
     <dependencies>  
          <module name="com.fasterxml.jackson.databind" export="true" />  
    </dependencies>  
</deployment>  

And also jar is available at

/opt/modules/system/layers/base/com/fasterxml/jackson/core/jackson-databind/main

I still haven't got a possible solution. Need some help.

PS : I also added the dependency

    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson2-provider</artifactId>
        <version>3.0.8.Final</version>
        <scope>provided</scope>
    </dependency>

Add the following lines at the end of WILDFLY_DIR/modules/system/layers/base/org/restcomm/slee/container/lib/main/module.xml

<module export="true" xmlns="urn:jboss:module:1.3" name="com.fasterxml.jackson.core.jackson-core"/>
<module export="true" xmlns="urn:jboss:module:1.3" name="com.fasterxml.jackson.core.jackson-annotations"/>
<module export="true" xmlns="urn:jboss:module:1.3" name="com.fasterxml.jackson.core.jackson-databind"/>

Got the reference from here which has another problem solved.
