Code:
package com;
import com.db4o.*;
import java.io.*;
public class Country {
public String countryName;
public int countryPopulation;
final static String filename = "C:\\abc.yap";
public Country(String countryName, int countryPopulation){
this.countryName = countryName;
this.countryPopulation = countryPopulation;
}
public Country(){
}
public String getCountryName(){
return countryName;
}
public void setCountryName(String countryName){
this.countryName = countryName;
}
public int getCountryPopulation(){
return countryPopulation;
}
public void setCountryPopulation(int countryPopulation){
this.countryPopulation = countryPopulation;
}
public void setData(String countryName){
new File(filename).delete();
ObjectContainer db = Db4o.openFile(filename);
Country c1 = new Country();
}
}
---------------------------------------------------------------------------------
add.jsp will display the layout and let user key in the countryName and countryPopulation.....after user click on save --> it will go to add2.jsp......
in add2.jsp it will display the value user key in...if the user confirm to save the data it will come display a message tell the user "you are successfully save"....i having problem in the last part ..... the confirm save data that part.....
how i pass the countryName and countryPopulation into the Country.java file...i need to pass the countryName and countryPopulation value into the setData method in java.....after i click on save, it will run the setData method....
it is possible to do this.....
