A package is not recognized in MyEclipse

I have created an EE project in MyEclipse.

I have one jsp file under "WebRoot" and it contains the following lines:

<%@ page language="java" import="java.util.*,java.sql.*,com.sp.model.*" pageEncoding="ISO-8859-1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
  <html>
     <body>
      <%
         String username=request.getParameter("username");
         String password=request.getParameter("passwd");

         UserBeanCL ubc=new UserBeanCL();
       %>
 ...

and I have also created a package called com.sp.model under "src" in MyEclipse.As you can see from the first line of the JSP code above, I have imported that package using import statement.UserBeanCL is just a normal JAVA class sits under that package, nothing special. Everything looks good in MyEclipse.It does find the package and the UserBeanCL class.

However, after I deployed the whole site into Tomcat and try run this JSP in browser, it always gives error and complains about line:

UserBeanCL ubc=new UserBeanCL();

The error is like: "UserBeanCL cannot be resolved to a type". The stacktrace is:

javax.servlet.http.HttpServlet.service(HttpServlet.java:722)

This error is confusing to me, since it only appears after deployment. Could experts help me on where to debug? Thanks in advance.

Solution

  • Use:

    <%@ page language="java" import="java.util.*,java.sql.*,com.sp.model.*" pageEncoding="ISO-8859-1"%>
