越來越會話

please suggest what i'll do..actually i'm using facebook java api and i'm getting some xml response with error code 100 

**my code is :**

此期間獲得異常的我的項目的一些代碼的一部分，請考慮這一點，並告訴在那裏我得到這個問題......在此我登錄的部分是確定和獲取後狀態200是確定當我試圖獲得的SessionID提示錯誤代碼100或無效的參數...越來越會話

   PostMethod post = new PostMethod("/login.php?login_attempt=1"); 
       post.addParameter("api_key", API_KEY); 
       post.addParameter("v", "1.0"); 
       post.addParameter("auth_token", token); 
       post.addParameter("email",user_Name); 
       post.addParameter("pass",password); 
       int postStatus=0; 
       try{ 
         postStatus = http.executeMethod(post); 
       } 
       catch(Exception e) 
       { 
       logger.info(" Exception Occur Here: "+e); 
       } 
       logger.info("LOGIN - Http status returned when executing POST: "+postStatus); 
       if(postStatus >=200){login=true;} 
       String sessionId=""; 
       try{ 
         sessionId = client.auth_getSession(token); 
        if(sessionId!=null) 
         { 
         login=true;  
         } 
         logger.info("Session key is " + sessionId+"---MSISDN---"+msisdn); 
       } 
      catch(Exception e) 
       { 
       logger.fatal(e);    ***// here i'm getting exception*** 
       } 

**and getting response is :**
