Create A Database Configuration File And Include All Other Files
Apr 19, 2014
I am creating an application in core java where i am using database. I need to create a database configuration file & include it all other files. So, how can i do that ?
Java Code:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:MYDSN","system","tiger"); mh_sh_highlight_all('java');
I cannot do this in an interface since only abstract methods exist there. I tried to create an another class file to extend it but my program is already extending other class i.e. javax.swing.JFrame..How can i implement this ? just by creating the object of that class in main method ?

I dunno why all the configuration files for ex: web.xml and struts.xml in any web application are xml files.

I have a library that I'm writing, the library contains a spring xml configuration file (lets say it's called libraryContext.xml) that sets the library up correctly for runtime, it also includes a test spring xml file that sets the library up for test by importing libraryContext.xml and overriding certain dependency injection beans (the library basically connects to a real database under normal conditions and uses dummy DAO's under test conditions). That bit is all fine.
The thing is, when I build the jar for the library (lets say it's called library-0.1.jar), the jar does not seem to contain the libraryContext.xml and that means that I can't import library.xml into my applications context.xml.
Basically, I have this line in my applications context.xml
Java Code: <import resource = "classpath:libraryContext.xml"/> mh_sh_highlight_all('java');
Unsurprisingly, since the xml file is not contained in the library-0.1.jar, the error I get is,
Java Code:
Offending resource: class path resource [applicationContext.xml];
nested exception is org.springframework.beans.factory.BeanDefinitionStoreException:
IOException parsing XML document from class path resource [libraryContext.xml];
nested exception is java.io.FileNotFoundException: class path resource [libraryContext.xml] cannot be opened because it does not exist mh_sh_highlight_all('java');
With respect to potential solutions to the above problem, I could:
1) physically copy the libraryContext.xml file (and its other *.xml and *.properties dependencies) into the application, but then I'd have to maintain duplicate files - I don't like this option.
2) find out if there is a better way to handle this problem from people who know better. E.g. is there a way to embed the libraryContext.xml file (and it's dependencies) into the jar file so that it can then be imported into the application. I've spent a while on google trying to figure this out and haven't come up with anything overly useful (perhaps I've been using the wrong search parameters).

I was just wondering how would I create a jar file that would open 3 other jar files when I open the jar file with my batch file it and when I type stop in the batch file it will out put the stop command into all 3 of the other jar files.
This is for my Minecraft server so I can launch them all at the same time and inStead of having to enter the commands in all the server batch files I just have to do the command in 1 I know their is things like multi craft to do this but I want the code so I don't have to use multicraft.

I have written a program (DOM Parser) that parses data from a XMl File. I would like to create an individual file with the corresponding name for each set of data parsed from the xml document. If the parsed output is Single, Double, Triple, I would like to create an individual xml file (Single.xml, Double.xml, Triple.xml)with those corresponding names. How do I create the xml files and give each file the name of my parsed data output?
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
[code]....

I am using Java Swing to create a GUI. I have some radio buttons on a JFrame that gets opened when the user makes a certain selection. I want to read a config file to have the radio buttons selected or deselected when the form is opened to indicate the current state of the radio button based on the saved config file.
How do I go about setting the radio button as selected (visibly selected) when I open up the JFrame?
I was trying to use RadioButton.setSelected(True); but this doesn't actually visibly select the radio button.

-I created the project with the checkbox "Create separate folder for sources and class files."
-I've tried running the program with the "mfq.txt" file in the root directory, the src directory, and the bin directory.
-I've even tried it in all three directories at once!
-I've also refreshed my project after each change in eclipse
-My error is the "FileNotFoundException" error
Here is the line giving me trouble
Scanner file = new Scanner(new File("mfq.txt") );
Where my code is wrong/where I should put my file? :tax:

I'm making a website with articles (like a blog). I have a webpage called admin.html where you insert the data of the article (title, post etc).
Admin.html calls to a servlet and this sends the information to a SQL Database and it stores and my index.jsp calls to database and show the articles.
This works perfect, and a non-programmer can insert new articles. The problem is that I need to create an .html file for every article/post and save it into my server online.
For example if I create "CoolArticle", I need the file "CoolArticle.html" and save it in my hosting.
How I can do it? I never have seen examples online, all were local, so I can't continue.

I have a shop and I use visual studio.net to create an Inventory application to manage my shop. So I am familiar with vb.net codes.
Now, I'm trying to built another Inventory application for my shop using java, 'coz now I'm using Linux Ubuntu for my OS desktop and there's no visual studio.net in linux.
So in vb.net, there's a module that I use for database connection that I can call from any form that I needed.
I searched google for the equivalent module for java and there is none. But, there's an example that use a new java class.
Here's the code in MySQLConnect.java :
Java Code:
public class MySQLConnect {
static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
static final String DB_URL = "jdbc:mysql://localhost/dbInventory";
static final String USER = "root";
static final String PASS = "root";
public static Connection ConnectDb() {

I want to create a singleton for DirContext for LDAP configuration, hence i have used the initialize on demandclass holder idiom as shown below
public class SlmApplicationContext {
/**
* inner class to hold the instance.
*/
private static class Holder {
private static DirContext instance = new InitialDirContext();
}
/**
* Method to get the singleton instance of this class.
* @return SlmApplicationContext
*/
public static SlmApplicationContext getInstance() {
return Holder.instance; }
...
}
Now the problem is if i close the DirContext.close(), when the next request comes the singleton wont work as the dir context is already closed, hence it will create a new dir context for each requests. Which breaks the singleton concept, hence how we can ensure the singleton works fine even with DirContext.close()?

So I'm trying to create a simple user database that I could eventually turn into a login system. I created a simple table on MySQL with a name and address for the sake of simplicity. I tried to create simple statement inside my main method that would connect to my MySQL server and when I run my program I get a ClassNotFoundException from "org.gjt.mm.mysql.Driver"..Here is what I have in my main method thus far:
public static void main(String args[]) {
try {
Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/data", "root", ""); //Connect
/*
conn.createStatement().execute("CREATE TABLE people (" + "id int(64) NOT NULL AUTO_INCREMENT," + "name varchar(255) NOT NULL," + "address varchar(255) NOT NULL," + "UNIQUE (id)," + "FULLTEXT(name, address))");
