Using MS Access Database In Java
Mar 19, 2014
I want to make a database and use it in my java program. I am thinking of using MS Access database, although I m not very sure, sine I will have to use this data later in the SQL database as part of C# program.
How to start to create and use MS database in java program.
I have seen in one tutorial that the steps are:
1. Install your database management system (DBMS) if needed
2.Install a JDBC driver from the vendor of your database
but I am not familiar with this. Any example, or is this above compulsory?

my aim is to make a runnable jar. I've made a program using swings which uses MS Access database to fetch records. So, I've used an absolute path to refer to the database for connection. Now, I intend to distribute this runnable jar to other people as well. So I guess the best option would be to embed the MS Access database as well in the jar file. But I don't know how to do that. Where should I keep the database in my Project Explorer ? Should I use a relative path etc.
This is my code:-
Java Code:
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
import java.util.Vector;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
[code]....

I'm given a task to generate an API (a jar file) where the access of a certain database is provided through the API. basic functionality: Client sends a query through the API to server and the Server responds with data.Since its and API, do I have to implement the code or is it enough if i gave just interfaces? what are the OOP concepts to focus on when designing a good API.

I have a textbox called "answer" and 10 different buttons on a form. Now what i would like to do is click the button and have the Button Text in the textbox with the already present text.
So if i click the button 1 it should automatically recognize the clicked button and have its text copied to textbox.
I know the '.get' method but lets say i have 100 buttons so i cant repeat it for every single one of them.
answer.setText(answer.getText() + ___________________);

How would you efficiently store and access stats in Java?
Java Code:
Monster[Attacked].takeDamage[Attackers damage modified by Defenders defense] mh_sh_highlight_all('java');
The purpose is for something like that... Trying to work towards that.
How would you store the stats for units (hp, mp, strength, defense, etc.) ?

Why is this not valid in java:
Both uses public with the same class/interface name.
Test.java:
public class Test implements Test{
/// Some codes
}
public interface Test {
///Some methods
}

I've got a CDI bean which is a facade for a JPA entity. Such entity has got a many to one relationship with itself and I've got the following method:
public Set<Account> getChildren() {
return this.children;
}
which is called in a JSF/Facelets page:
<h:commandLink action="#{accountController.destroy}" value="#{bundle.ListAccountDestroyLink}" rendered="#{item.children.size() == 0}"/>I then decided to return an unmodifiable set and changed getChildren() accordingly:
public Set<Account> getChildren() {
return Collections.unmodifiableSet(children);
}
The page now reports this error:
java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access a member of class java.util.Collections$UnmodifiableCollection with modifiers "public"
at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:65)
at java.lang.reflect.Method.invoke(Method.java:588)
[Code] ....
javax.el.BeanELResolver is incorrectly failing because it's trying to invoke the size() method using reflection without correctly taking into account the method visibility (which is indeed invokable programmatically). I'm running NetBeans 6.8, Glassfish 3.0 and jdk1.6.0_17.
Is this a bug in BeanELResolver?

I have a doubt about how to design a web application which has their persistent objects in a service layer in a remote server, i mean a business application. So, once we have a web application as a client of this remote business application, how those persistent objects should be mapped in web front?
Should I either pack all jpa annotated classes into the web front application or there is another neat way to do this?
I was intending in copy all persistent classes present in the remote business application into the web app package, i know it's not the best way to get what i need.
What is a more appropriate design for a web application which must get some objects from a remote business application and persist some other objects there?

In MVC, M is the model, V is the view and C is the controller. But whatever projects I have made till now, I have a separate layer called data layer where I do all the database operations. In MVC, are we saying that the database operations are within the controller layer? That's quite a little mismatch! Separation of layers yet merge of controller & database operations!!

I would like to make a database using HTML and Java. I already made something like this using swing. I am just looking for some pointers here. I just started looking into Java Play 2 and I have a feeling this is what I am looking for. JavaEE is very complicated and I have read that it is being phased out. What is your opinion on this?
I want to make a static HTML page and put it on my home network and treat one of my computers as the sever accessing mySQL.
