JavaFX 2.0 :: Other Methods To Load CSS File From MySQL DB Table
Jan 29, 2015
I am trying to load a CSS file from a mySql DB table (each row represent a customer that use the application, and each one can set his own CSS file).
How can I convert the Stream / String that I loaded from the Clob column to something that I can use here XXXX
scene().getStylesheets().add( XXXX );
I found alot of examples, but they all talking about files from filesystem, or URLs. My CSS file is in the application memory. I want to prevent the option to write my string as a new file and then read it again. I have no problem with loading the CSS file from database, this part is O.K.

I am facing the following scenario:
1- Take information from distinct columns from two different tables - OK
2- Insert this information into a new table.
I have created a ArrayList and inserted all the information that I need but now I am trying to put this ArrayList into the new table and I am not sure how to do it. I have done research and tests but unsuccessfully.

I m new to programming and am working on the college project. I have MySQL 5.6.20, Eclipse Kepler and Apache Tomcat 7.0.54. I m trying to retrieve the whole table from MySQL schema into a jsp. All the possible things i can do, i have already tried, but none of them are working.
The following attachment contains the whole project. I have my sql connection code in Sample.java file, which i want to get working in Fetch.jsp on the Submit button click. But it shows the tomcat error as localhost:8080/Sample HTTP Status 404-/Sample ; type Status report; message /Sample; Description The requested resource is not available.

How to define Cell in the table by table event?
I need to process one component drag to the table. I misunderstand, how I can see to which Cell fall the component. I tried to use Event and Mouse event handlers in my custom Cell, but they do not work. I can copy the drag event to the table and table handles it, but how to get needed Cell I cant understand.

The problem is that I populate the table with autoincrement primary key. I don't want it to be visible. I have been googling for hours to find no solution. It seems that sql/mysql provides no solution by selecting all table columns except one. So I wonder, how I could overcome this problem. Here is some of my code:
public void tableChanged(TableModelEvent e) {
int row = e.getFirstRow();
int col = e.getColumn();
model = (MyTableModel) e.getSource();
String stulpPav = model.getColumnName(col);
Object data = model.getValueAt(row, col);
[Code] .....
The ID is used in
stmt.addBatch("update finance.fin set " + stulpPav + " = " + duom
+ " where ID = " + studId + ";");
I tried to omit ID from my SELECT statement, I tried to put Date as a first element in data[iEil][0] but neither options were successful. Data hasn't been changed in database. NOW, everything works fine, except I don't want ID column to be visible in my table.

I am new to javafx and my goal is to basically just test if my java code works with Mysql. What I'm planning to do is to display one data of the sakila database into a Label named greetingLabel. And I can't seem to find where i went wrong so i'll show you my whole code.
Here is the main code for my controller class from scene builder:
package main;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;

Here is the error displayed when pressing the button

I am building an application that shows tables with large amounts of data containing columns that should display a thumbnail. However, this thumbnail is supposed to be loaded in the background lazily, when a row becomes visible because it is computationally too expensive to to this when the model data is loaded and typically not necessary to retrieve the thumbnail for all data that is in the table.
I have done the exact same thing in the past in a Swing application by doing this:
Whenever the model has changed or the vertical scrollbar has moved:
- Render a placeholder image in the custom cell renderer for this JTable if no image is available in the model object representing the corresponding row
- Compute the visible rows by using getVisibleRect and rowAtPoint methods in JTable
- Start a background thread that retrieves the image for the given rows and sets the resulting BufferedImage in a custom Model Object that was used in the TableModel (if not already there because of an earlier run)
- Fire a corresponding model change event in the EDT whenever an image has been retrieved in the background thread so the row is rendered again
Btw. the field in the model class holding the BufferedImage was a weak reference in this case so the memory can be reclaimed as needed by the application.
What is the best way to achieve this behaviour using a JFX TableView? I have so far failed to find anything in the API to retrieve the visible items/rows. Is there a completely different approach available/required that uses the Cell API? I fail to see it so far.

I have a small application that I have been working on for several months. It works great. Now when I created an executable .jar file for it, it will not load data from a .csv file. I have tried looking into everything I can think if. I checked file paths, etc. I am using OpenCVS to read the csv. Is there an issue with that when you include it into another .jar file? I am trying to log if there is an error but I don't even get an error. I just doesn't run past that statement...

I'am trying to finish my first Java Game with the slick2D library. I had it all working in eclipse but when i was about to make a jar file of it i did realize that i had to use class loader to load my png - SpriteSheets. But now to the problem. My ResourceLoader Class looks like this:
public static InputStream load(String path){
InputStream input = MyResourceLoader.class.getResourceAsStream(path);
if(input==null){
input = MyResourceLoader.class.getResourceAsStream("/"+path);
}
return input;
}
My init-Method in the BasicGame class, where i try to load my png-files looks like this:
public void init(GameContainer arg0) throws SlickException {
InputStream inputStream1 = MyResourceLoader.load("images/piratR.png");
sprite1 = new SpriteSheet("",inputStream1,32,32);
InputStream inputStream2 = MyResourceLoader.load("images/monkey.png");
sprite2 = new SpriteSheet("",inputStream2,32,32);
animation1 = new Animation(sprite1,200);
animation2 = new Animation(sprite2,250);
}
And that works fine for loading the FIRST png-file(eg piratR.png), but whenever i try to load another file it just loads the first one again. So in this case sprite1 and sprite2 looks the same though there are different images.
When i switch the "Load order" and Load sprite2 before sprite1 both animations looks different, so I'm sure that i have two different pictures and its always the one that i load first that will get loaded to all the other SpriteSheets.

I can not load my jar file and it is telling me it can not find the main and I thought I had the right files in the right spots. Do I need the .class of my main file for it to make the jar file. I do not understand If I need to make a .jar out of the main then add all the other files to create the jar.
added manifest
adding: Board.class(in = 2431) (out= 1371)(deflated 43%)
adding: Cell.class(in = 1702) (out= 959)(deflated 43%)
adding: Mark.class(in = 1195) (out= 673)(deflated 43%)
adding: Outcome.class(in = 960) (out= 538)(deflated 43%)
adding: Player.class(in = 832) (out= 472)(deflated 43%)

I am using JPF controllers. Already, i am loading a properties file in the controller
(using annotations @Jpf.Controller(messageBundles = { @Jpf.Message Bundle(bundlePath = "validation.validator.Messages") },).
I have a problem. Depending on one of the request variables, i need to load different properties files. All these property files have same keys, but with different messages. I need to take the user to different sites(though internally, the backend logic remains same...Look and feel of the front end along with messages to be shown change to make the users feel they are being directed to a different site).
I am thinking of loading the properties file from the JSP when the user logs in first time from login page so that these properties are available until the session expires & not read the properties file in Controller.

I have a little problem in my Java FX application. in a tableview, I add records whatever... And i have a button that delete the selected record in the tableview, This button delete too the related record in a database.
When I select a row in this table , I store the ID of that record in a global variable to have it available . Thus, when I click on the delete button, delete the record from the database based on the ID that I stored in the global variable.
The problem is that tableview has a curious property. If I select the last row and I click on the delete button ( removing the last record of the tableview ) , the next higher row is automatically selected ; and causes the ID value stored change .
The row is deleted in the tableview is correct but apparently , when it comes to the method deletes the record from the database, the global variable ID is already updated and delete another record.
I would like to disable that property of the table so that the row can be selected only by the mouse ... or some other solution .

@Override
public void initialize(URL url, ResourceBundle rb){
table.getSelectionModel().setSelectionMode(SelectionMode.SINGLE);
table.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<Object>(){

Release 8u40 introduces the TextFormatter concept in the text input field area. It is currently a new property of the TextInputControl class. This is definitely a more elegant way to deal with validation than overriding "replaceText(...)".
Shouldn't this property also be available in list, table and tree cells? Are there plans to do this (before we make our own implementation) ?

I'm trying to load a class file into Oracle using loadjava and I get the following error:
ORA-29552: verification warning: java.lang.UnsupportedClassVersionError: helloworld (Unsupported major.minor version 51.0)
Presumably this is related to an inconsistency between the jdk that I used to compile helloworld and the Oracle JVM? Or something like that?
My JAVA_HOME is C:Program Files (x86)Javajre7bin
My javac version used to compile the code is javac 1.7.0_15
java -version is "1.7.0_15"
When I do a find on java.exe in the oracle installation directory (I'm running 11.2) I get
J-PC:J >find -name java.exe
./product/11.2.0/dbhome_1/jdk/bin/java.exe
./product/11.2.0/dbhome_1/jdk/jre/bin/java.exe
./product/11.2.0/dbhome_1/jre/1.5.0/bin/java.exe
Finally, the jdbc jar is ojdbc6.jar
Btw the code is just the usual little tester:
import oracle.jdbc.driver.*;
public class helloworld {
public static String hello()
{
return "Hello World";
}
public static String hello(String s)
[Code]...
How can I get this class file loaded?
