How To Add Database To NetBeans Project When Making Setup
Aug 21, 2014
I have completed an assignment for my university in which I had to make a Java NetBeans project. My project is now completed but now I have to make a setup of my NetBeans project and give the university the setup file, only.
My question is, the software I made has a database attached to it, meaning the purpose of the software is to be used with the database. Values must be saved in the database, deleted from the database etc.. I have used MySQL database connections with the JDBC driver
I have used exe4j to make the .exe file and Setup Factory to make the exe file and setup file respectively. Once I make the setup and run the setup, the application works, ON MY COMPUTER. The computer which made the software. But once I take it to a computer in which MySQL was not installed, the setup installed, but the software did not work.

First I was using this way how to get connection and all was fine.
con = DriverManager.getConnection("jdbc:derby:memory:datab;create=true");
But now I have to change it to DataSource and how I find out derby had class ClientDataSource for this but for the hell I can't find out how to setup that virtual DB.
ClientDataSource ds = new ClientDataSource();
con = ds.getConnection();

I tried many times to return a string from java project to an android project But it keeps sending incorrect values as in 2 as it should be 1 here is an example.
Java Project:
boolean somethingboolean = false;
if(something.equals("1")){
somethingboolean = true;
}
public static String getString(){
if(somethingboolean == true){
[Code]...
Android project:
System.out.println(JavaProject.getString())
and in the android project it prints "FALSE"
So what should i do?

I am trying to set a picture in the background of my GUI. I had already made the GUI with the all the required buttons and labels. So I was trying to separately make a class which extends JPanel and add a picture to a panel by overriding the paintComponent() method, and then added it to a frame (I did not set the default layout of the frame, so it was the default...), and it worked very fine. Here is the code:
Java Code:
private BufferedImage image;
public ParentPanel() {
try {
image = ImageIO.read(getClass().getResource("/com/dev_nna/scheduler/UI/1405188.png"));
} catch (IOException ex) {
ex.printStackTrace();
[code]....
Then I needed to add this panel with background picture to the background frame of my already made frame with all the buttons on it.The layout of the parent frame of my GUI was BorderLayout(50, 50), panels (with buttons) were added to it n the north and south positions.
Then I tried to add a JPanel with the background image to the parent frame (of my GUI), (I wanted it to elapse the entire frame, and come under all the buttons and controls, which were only present in the north and south positions of the border layout), and then the panels holding the buttons to the north and south postions of this panel, everything disappeared.
If I don't do anything except adding this panel with the background image to the parent frame, it only takes up the place not taken up by the two panels on the frame (Border Layout)
how to add this panel to the parent frame of my GUI such that it elapses the entire parent frame's background, and the panels containing the buttons should sit on it.
IMPORTANT PARTS OF CODE:-
Java Code:
//TOP LEFT PANEL
JPanel topleftpanel = new JPanel(new FlowLayout(FlowLayout.LEFT, 5, 5));
parentPanel_top.add(topleftpanel);
topleftpanel.setOpaque(false);
[code]....

I am new to Java. I am from .net background.I am trying to setup Sonar server. In one of our training sessions on Sonar, the instructor did the anaysis of solution using pom.xml file and then calling mvn sonar:sonar. I am trying to replicate the entire setup locally.
1. I installed JRE 7. When I run , java -version, it shows,
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)
2. I download sonar 3.5 and extracted it to new folder
3. In that folder I installed sonar-runner 2.4
3. setup the path and sonar_runner environment variable
4. downloaded jtds-1.3.1 and placed the jar file in mssql folder of sonar
5. I create database sonar with username and password as sonar
6. changed sonar-runner.properties for sql server connection
7. changed sonar.properties for sql server connection
8. Ran Sonar.bat and found that it created tables in the sql server db. To me the command prompt seems like it is hanging as after creating table graphs, the last line is
"jvm 1 | 2014-07-20 13:03:34.967:INFO::Started SelectChannelConnector@0.0.0.0:
9000 "
Is it supposed to stay like this always or should i closed this command prompt by pressing CTRL+C?
9. Now when i run mvn-sonar:sonar, it says mvn is not recrognizes as internal or external command. A quick search on google showed that I need to install Apache maven something I belive. What is this or how do I solve this issue so that the command mvn sonar:sonar can work?
10. I would like to use c sharp ecosystem plugin. But when I browse to C# Plugin - SonarQube - Codehaus , I am confused as what to select? i.e. version 3.2, 3.1, 3.0
11. So if I do a system restart and everytime I have to use sonar, should i run sonar.bat and then do mvn sonar:sonar after modifying the pom.xml file?

I create my own TreeCell class to customize the look of the tree items of a TreeView which is displaying java.nio.file.Path information.
To setup the CellFactory of the TreeView I used the following:
pathTV.setCellFactory( (TreeView<Path> tv) -> {
return new MyCustomTreeCell();
} );
This works... Now I tried to do some other things with my custom tree cell class so I created an instance of it
MyCustomTreeCell mctCell = new ...
Later I changed the code to setup the CellFactory
pathTV.setCellFactory( (TreeView<Path> tv) -> {
return mctCell;
} );
This doesn't work ... I did not see anything in my TreeView...
Here is the MyCustomTreeCell class:
public class MyCustomTreeCell extends TreeCell<java.nio.file.Path> {
private final ImageView icon;
public MyCustomTreeCell() {
super();
icon = new ImageView();
[Code] .....

Any documentation that deals with assigining an icon to your application? I have tried the:
"stage.getIcons().add(new Image(this.getClass().getResourceAsStream("myicon.png")));"
Code as suggested on the web. It looks like this changes the icon in the window decoration only, which doesn't actually show on my Ubuntu desktop with Unity. What I really want is a custom icon for when I alt-tab through open applications. Currently it shows the default grey question mark. How do I assign an icon to the application.

I've setup an array that I would like to analyze by adding up the contents of each column, however, the out of bounds exception pops up when I try to execute the program. I know the book usually expresses this operation the other way around, where the row is the argument of the first for statement, but I've set my array up where I need to add each row before moving to the next column.
vowelCounter is a 5x3 array.
// Display the line which had the most number of vowels
public static int maxVowelSentence() {
int max = 0, sum = 0;
int sentence = 1;
for (int row = 0; row < vowelCounter.length; row++) {
max = vowelCounter[row][0];
[Code] ....

I'm making an import/export of xml - I have the import of xml sorted I'm just trying to finish off the export. My export class is called XmlWriter.java. Inside the class I have an updateFile method to update an xml file as such:
public void updateFile(Environment environment,Document doc)
{
// code
}
I then in my main method have
public static void main(String argv[]){
//declare new object of class
XmlWriter xmlWriter = new XmlWriter();
//test testUpdate method
// xmlWriter.testUpdate();
Environment environment = ;
[code]....
I don't know what to make my variables equal to - eclipse keeps trying to use null but obviously that won't work. The Environment is another class that just contains getters and setters for the 3 different databases (that are in the xml file) and the getter/setter for the environment ID (also in xml file).

I have a jsp with an img tag whose src is set to request a servlet to display a chart. This is called from another jsp form where user can select various filters. The first time the request is made all works great. but if the user changes the filter settings and and makes the servlet request a second time the chart stays the same. I have verified the new filter values are being set but the servlet is only being called on the initial request.at the head or called servlet I have(I also call a jquery empty on the div that holds the chart between requests. at the moment it just displays the former chart). It is like it is using cache:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setHeader( "Pragma", "no-cache" );
response.setHeader( "Cache-Control", "no-cache" );
response.setDateHeader( "Expires", 0 );

I prompted the user to enter inches of rainfall for seven days and stored them in an array. Now, I am trying to display a histogram of this data using a nested loop, but for each inch, I have to display a * like this:
Rainfall Histogram:
****
***
**
******
********
**********
**
The only way I know how to display a number of *s according to user input is by an if statement. I copied and pasted from a similar class assignment I did, so what I have so far is pretty messy and nonsensical:
static char DetermineRainfall(int inches)
{
System.out.println("Histogram");
//char inches;
for(inches = 0; inches < 7; inches++)
{
for(int j = 0; j < 1; j++)
{
if (rainamount > .9 && rainamount <= 1)
inches = '*';
return inches;
}
}

I am trying to run a Java applet (.jnlp) file through OSX. The purpose of the applet is to upload files to an SQL server. When I try to run the applet, I get an "Unable to launch the application" error because "No application resources are specified for this platform" After some digging , we noticed there are only resource instructions for "Windows".
Would there be any way possible to make this compatible in an OSX environment through a few alterations to the code, or would this be an issue that the original developers would have to resolve?
Here is the specific code pointing to the Windows Resources:
<resources os="Windows" arch="amd64">
<j2se version='1.6+' initial-heap-size="64m" max-heap-size="512m"/>
<jar href='http://192.168.1.140:7001/MagicInfo/uploader/uploader.jar' main='true' />
<jar href='http://192.168.1.140:7001/MagicInfo/uploader/lib/jnlp.jar' download="eager" />
<jar href='http://192.168.1.140:7001/MagicInfo/uploader/lib/transform.jar' download="eager" />
