无法实例化bean类

我想互动与春天休眠在我的GWT项目，下面是我的代码无法实例化bean类

public class MyWebServiceImpl extends RemoteServiceServlet implements 
    MyWebService { 

public void myfirstmethod() { 
    // TODO Auto-generated method stub 

} 

public String signIn(String userid, String password) { 
    ApplicationContext ctx = new ClassPathXmlApplicationContext(
    "applicationContext.xml"); 
    MySQLRdbHelper rdbHelper = (MySQLRdbHelper) ctx.getBean("ManagerJobs"); 
    **//THIS IS THE POINT WHERE IT THROWS THE EXCEPTION** 

    return rdbHelper.getAuthentication(userid, password); 
}

}

 public class MySQLRdbHelper { 


private Session session; 
private SessionFactory sessionFactory; 
    /* FOR COUNT QUERY 
    * session.createCriteria(RuleSet .class) 
    .setProjection(Projections.projectionList() 
      .add(Projections.rowCount())) 
    .add(Subqueries.geAll("entry_id", bolgsEntries)) 
    .list(); 
*/ 
public void setSessionFactory(SessionFactory sessionFactory) { 
    this.sessionFactory = sessionFactory; 
    } 

public String getAuthentication(String userid, String password) 
{ 
    //Some detals like credit card are commented in the class 
    User users = null; 
    session = sessionFactory.openSession(); 
    Criteria crit = session.createCriteria(User.class); 
    crit.add(Restrictions.eq("userName", userid)); 
    crit.add(Restrictions.eq("password", password)); 

    List rsList = crit.list(); 
    for(Iterator it=rsList.iterator(); 

    it.hasNext(); 
    ) 
    { 
     users = (User)it.next(); 
     System.out.println(users.getUserName()); 
    } 
    session.close(); 
    return users.getUserName(); 
}

}

  APPLICATIONCONTEXT.XML 
     <?xml version="1.0" encoding="UTF-8"?>

     </list> 
     </property> 
     </bean> 
     <bean id ="ManagerJobs" class= "patient.persistence.MySQLRdbHelper"> 
     <property name="sessionFactory" ref="sessionFactory" /> 
    </bean>

这是例外

你缺少你的classpath SLF4J通过

java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

指示得到它，并添加到应用程序。

，谢谢，我已经添加了SLF4J的API-1.3.1.jar和SLF4J-log4j12-1.5.6.jar，但问题仍然存在任何建议感谢 – junaidp 2011-06-04 04:48:30

@junaidp用相同的加SLF4J罐子版本。同样的问题意味着你看到相同的'java.lang.NoClassDefFoundError：org/slf4j/LoggerFactory'吗？ – 2011-06-04 05:34:04

@ junaidp你还把你的罐子放在哪里？我记得在托管模式下，我必须将slf4j jar放入WEB-INF/lib中。他们没有从普通的课程路径中获得。 – 2011-06-04 05:38:32

This is my Controller file.......... 
@Controller 
public class AutoCompleteController { 
    //@Resource(name = "blCatalogService") 
    //protected CatalogService catalogService; 
     @RequestMapping(value = "/AutoComplete", produces = "application/json") 
     [email protected]<Product>AutoComplete(HttpServletRequest request, 
      HttpServletResponse response,Model model, CatalogService catalogService){ 
    List <Product> list=new ArrayList<Product>(); 
    String autostr=request.getParameter("autocomp"); 
    System.out.println("AutoComplete Controller" + autostr); 
    try { 
     //database query searchString; 
     CatalogService catalogService1=new CatalogServiceImpl(); 
     list = catalogService1.findProductsByName(autostr); 
     System.out.println("Result:"+list); 

    } 
     catch (Exception e) { 
     System.out.println("Error inside AutoComplete Controller"); 
      e.printStackTrace(); 
     } 
     return list; 

    } 

    } 
    This is my js File 


function ajaxAutoComplete(a) 
{ 

    var querystring = "&isAjax=1&autocomp="+jQuery("#autocomp").val(); 
    jQuery.ajax({ 
     url: a, 
     dataType: "json", 
     type: "post",`enter code here` 
     data: querystring, 
     success: function (data){} 
    }); 
} 
that the time it will produced that error. 
500 Could not instantiate bean class
