i'm using hibernate3.1 and eclipse 3.1. can anyone help????

this is my object file.

package model;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;


public class User implements Serializable{
private String empNo;
private String firstName;
private String lastName;
private String company;
private String department;
private String designation;
private String extNo;
private List userInfo = new ArrayList();



public String getCompany() {
return company;
}
public void setCompany(String company) {
this.company = company;
}
public String getDepartment() {
return department;
}
public void setDepartment(String department) {
this.department = department;
}
public String getDesignation() {
return designation;
}
public void setDesignation(String designation) {
this.designation = designation;
}

public String getEmpNo() {
return empNo;
}
public void setEmpNo(String empNo) {
this.empNo = empNo;
}
public String getExtNo() {
return extNo;
}
public void setExtNo(String extNo) {
this.extNo = extNo;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}

this.lastName = lastName;
}
public List getUserInfo() {
return userInfo;
}
public void setUserInfo(List userInfo) {
this.userInfo = userInfo;
}
}

what's wrong??? can anyone help me to figure out?? it's urgent.

Looks like a simple bad classpath. Configure it in Project -> Properties.

sorry coz i can't get what u mean. can u tell me in a clearer way? thanx.

Your java VM can't find User.class. Search through the dialogs that configure whichever eclipse plugin you're using; you're looking for a text field called "Class Path" or similar. Type in the name of the directory that contains the "model" directory. If you use different directories for .java files and .class files, it's the one with the .class files that's important.

you need to put the build path of your code in the classpath of the hibernate console configuration. Done when you create the configuration or by right clicking and click Edit.

i finally can see the table in my mysql administrator. now my problem is when i create a jsp to test the data. i failed to do so. after i key in the data, the webpage shows this error:

java.lang.NoClassDefFoundError: model/User
servlet.UserServlet.doPost(UserServlet.java:41)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)


the servlet java file is as shown below:

package servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import model.User;


/**
* Servlet implementation class for Servlet: UserServlet
*
* @web.servlet
* name="UserServlet"
* display-name="UserServlet"
*
* @web.servlet-mapping
* url-pattern="/UserServlet"
*
*/
public class UserServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {
/* (non-Java-doc)
* @see javax.servlet.http.HttpServlet#HttpServlet()
*/
public UserServlet() {
super();
}

/* (non-Java-doc)
* @see javax.servlet.http.HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}

/* (non-Java-doc)
* @see javax.servlet.http.HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String title = request.getParameter("title");

model.User user = new model.User();

user.setEmpNo(title);
Object [] args = {user};
Class [] argsType = new Class[]{model.User.class};
Object ob = ejb.EJBInvoker.invokeRemoteEJB("jnp://127.0.0.1:1099",bean.UserBHome.JNDI_NAME,"saveUser",args,argsType);
user = (model.User)ob;

getServletContext().getRequestDispatcher("/default.jsp").forward(request, response);
}
}

i'm using eclipse 3.1 and hibernate 3.1. i create teh UserServlet.java in a package in dynamic web project.

it seems that problem is in your classpath. JVM cant find the model.User.class .

when u are working with jsp please add these classes externally before configure.
