JSP调用WEBSERVICE的问题

最近在做webservice的测试，使用Myeclipse5.1.1创建webservice，名字为user,在服务中添加两个方法

public   String   example(String   message)   {
return   message;
}

public   String[]   userCheck(String   username,String   password){
String   s[]   =   null;
if   (username.equalsIgnoreCase( "robin ")   &&   password.equalsIgnoreCase( "password ")){
s   =   new   String[3];
s[0]   =   "robin ";
s[1]= "robin ";
s[2]= "robin ";
}
return   s;
}

发布到tomcat6中，然后通过myeclipse生成客户端，在客户端中调用服务进行测试。在客户端中调用正常。接下来想在JSP中实现用户身份验证功能，即有叶面提交用户名和密码，由wenservice返回。
于是编写身份验证bean
public   class   tt   {

private   static   userClient   uc   =   new   userClient();
private   static   userPortType   ut   =   uc.getuserHttpPort();

public   String   getExmple(){
String   s   =   ut.example( "robin ");
return   s;
}

public   List   getUser(String   username,String   password){
List   s   =   null;
ArrayOfString   as   =   (ArrayOfString)ut.userCheck(username,password);
try   {
s   =   (List)as.getString();
}catch(Exception   e   ){
s   =   null;
}

return   s;
}


public   static   void   main(String[]   args)   {
//   TODO   Auto-generated   method   stub

tt   t   =   new   tt();
System.out.println(t.getExmple());
List   l   =   t.getUser( "robin ", "password ");
if(l==null){
System.out.println( "dd   ");
}else{
System.out.println(l.size());
}

//System.out.println(.size());

}

}

在eclipse中直接运行，正常。但是当我在JSP中进行引用的时候出现问题
<%@   page   import= "com.zoo.tt "   %>
      <%
        tt   t   =   new   tt();
        out.println(t.getExmple());
        List   l   =   t.getUser( "robin ", "password ");
        out.println( "________ ");
        out.println(l.size());
        out.println( "________ ");
          %>

字符串的引用没有问题，就是在List调用时出错
Unable   to   locate   jaxb.properties   for   package   com.zoo.service.user
