Web Programming with Servlets

1. Write a HTML page which captures the user’s personal data (fist and last name, birthday, sex, and CNP) by using a form . The form’s action component is a servlet which verifies the user’s data and responds with a welcome page that echoes all data.

2. Write a HTML page which is used repeatedly to capture data on companies (name and business description). Information about a company is encapsulated in a Company object and added to a list companies stored in the server in the session public domain. In the same page there is another form with a submit button List for displaying the company list in a conclusive HTML page.

3. Use the following Java Beans for manage in a little site employees of some companies:

import javax.servlet.*;

import javax.servlet.http.*;

import java.io.*;

public class NameBean {

private String firstName ;

private String lastName;

public NameBean() {}

public NameBean(String firstName, String lastName) {

setFirstName(firstName);

setLastName(lastName);

}

public String getFirstName() {

return(firstName);

}

public void setFirstName(String newFirstName) {

firstName = newFirstName;

}

public String getLastName() {

return(lastName);

}

public void setLastName(String newLastName) {

lastName = newLastName;

}

}

public class CompanyBean {

private String companyName;

private String business;

public CompanyBean(String companyName, String business) {

setCompanyName(companyName);

setBusiness(business);

}

public String getCompanyName() { return(companyName); }

public void setCompanyName(String newCompanyName) {

companyName = newCompanyName;

}

public String getBusiness() { return(business); }

public void setBusiness(String newBusiness) {

business = newBusiness;

}

}

import javax.servlet.*;

import javax.servlet.http.*;

import java.io.*;

public class EmployeeBean {

private NameBean name;

private CompanyBean company;

public EmployeeBean(NameBean name, CompanyBean company) {

setName(name);

setCompany(company);

}

public NameBean getName() { return(name); }

public void setName(NameBean newName) {

name = newName;

}

public CompanyBean getCompany() { return(company); }

public void setCompany(CompanyBean newCompany) {

company = newCompany;

}

}

The user can insert persons and companies and then associates each person with a company. Finally a list of all persons with their company and a list of all companies with their employees can be asked.

Hint:

1. Find information on JavaBeans in the course lectures slides.

2. Use the session public domain for store three Map-s: Persons, Companies and Employees. Search the persons and companies in these maps.
