Hi,

    No, I do not think Creation of Module is possible via   Management API.

    However you can use CLI based java API to achieve the same:

import java.io.IOException;
import java.util.Map;
import org.jboss.as.cli.CommandContext;
import org.jboss.as.cli.CommandContextFactory;
import org.jboss.as.cli.CommandLineException;
 public class ModuleAdd
{
   public static void main(String[] args) throws CommandLineException, IOException
   {
      String host = "localhost";
      int port = 9999;
      ModuleAdd moduleAdd=new ModuleAdd();
      CommandContext ctx = CommandContextFactory.getInstance().newCommandContext("admin","admin123".toCharArray());
      ctx.connectController(host, port);
      moduleAdd.createSecurityDoModuleAdd(ctx);      
      ctx.disconnectController();
   }


       public void createSecurityDoModuleAdd(CommandContext ctx)
       {   
         System.out.println("Setting up the module with CLI");
         try {               
                String command="module add --name=aaa.bbb --resources=/NotBackedUp/DELETE/ojdbc6.jar --dependencies=javax.api,javax.transaction.api";
                ctx.handle(command);
             } 
         catch (CommandLineException e) 
             {
                e.printStackTrace();
             } 
         finally 
             {
                ctx.terminateSession();
             }          
        }
}

  For example when you open a Terminal and export JBOSS_HOME in the terminal  and then when you run the above code you wil see a Module is added in JBoss AS7.1.3  or higher version of it as following:

AS7.1.3/modules

/aaa/

└── bbb

    └── main

        ├── module.xml

        └── ojdbc6.jar

module.xml as following:

=================

<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="aaa.bbb">
    <resources>
        <resource-root path="ojdbc6.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
    </dependencies>
</module>
