Answer 1

try adding following line to JBoss home \\modules\\sun\\jdk\\main\\module.xml

 <dependencies>
      <system export="true">
         <paths>
           ..


           <path name="sun/net/www" />
        </paths>

Non-API packages from the JRE are not exported by default by the JBoss modules environment.

See Class Loading in AS7 , section Accessing JDK classes , for a solution.
