the password callback class can't be found by tomcat when I upload my web service with rampart security

  
 Hello I made an axis 2 web service using Eclipse, then I decided to add rampart security, so I added the PWCBHandler.java class to my dynamic project and I added to policy in my services.xml
But when I make a .aar file, I go to the folder of my project and I see that only the source class file but I can't find the PWCBHandler.class is in the project folder and when I make a request, I get the message that com.gismo PWCBHAndler class cannot be found
