how do i force down a pool member in java?

 
 public void forceDownMember(PoolMember member) { 
  
         //set up a sessionstate obj. 
         iControl.LocalLBPoolMemberMemberSessionState sessionstate = new LocalLBPoolMemberMemberSessionState(); 
         iControl.CommonIPPortDefinition sessionipportdef = new iControl.CommonIPPortDefinition(); 
  
  
  
         sessionipportdef.setAddress(member.getHostip()); 
         sessionipportdef.setPort(member.getHostport()); 
  
         sessionstate.setMember(sessionipportdef); 
         sessionstate.setSession_state(CommonEnabledState.STATE_DISABLED); 
  
         iControl.LocalLBPoolMemberMemberSessionState[][] lbpoolmembersessionstateArray = {{sessionstate}}; 
  
         //set up member state obj 
         iControl.LocalLBPoolMemberMemberMonitorState monitorstate = new LocalLBPoolMemberMemberMonitorState(); 
         iControl.CommonIPPortDefinition monitoripportdef = new iControl.CommonIPPortDefinition(); 
  
         monitoripportdef.setAddress(member.getHostip()); 
         monitoripportdef.setPort(member.getHostport()); 
         monitorstate.setMember(monitoripportdef); 
         monitorstate.setMonitor_state(CommonEnabledState.STATE_DISABLED); 
         iControl.LocalLBPoolMemberMemberMonitorState monitorstatArray[][] = {{monitorstate}}; 
  
          
  
         try { 
             String tmp[] = {member.getPoolName()}; 
             interfaces.getLocalLBPoolMember().set_session_enabled_state(tmp, lbpoolmembersessionstateArray); 
             interfaces.getLocalLBPoolMember().set_monitor_state(tmp, monitorstatArray); 
             System.out.println("Took down " + member.getHostip() + " " + member.getHostname()); 
         } catch (Exception e) { 
             System.out.println("forceDownMember: " + e.toString()); 
         } 
  
  
     }
