Arraylist在JSP scriptlet中不起作用

Question

When I am trying below code in Java 1.6/1.7 with Jboss 4.0 I am getting below exceptions. I don't have option here to use jstl.

Servlet.service() for servlet jsp threw exception

My Jsp file is below :

    <%@ page import="java.util.*" %>  

    <% ArrayList<String> list=new ArrayList<String>();  
       list.add("Hello");  
    %>  

    <%= list.get(0) %>

Answer 1

List <String> list = ArrayList<String>(); Try this with List not ArrayList

Answer 2

Provide fully qualified class name:

java.util.ArrayList<String> Orig_office_type = new java.util.ArrayList<String>();

This will resolve the issue.
