Using Netbeans 7.4, I have hand coded a GUI (SE desktop distributable application), created a single table database (Java DB using 'Embedded Driver' connection).
As I'm at that stage of creating a (non-CRUD) database application using Hibernate 2.0, is it possible to use the Java DB/Embedded Driver with Hibernate or does it need to be a 'localhost' connection?

I'm reasonably new to Java and NetBeans.
I'm developing an SE Java application which allows the user to view a database that I've created. I've done the data binding to a JTable but don't see any data. I've read the Derby/Java DB manual and it seems that I need to put data into this Embedded database (single table). All I want to know is how to put the data in - can I copy the files from '.netbeans-derby' folder or do I have to utilise another method?

I have an embedded browser in a standalone java app running on windows. The browser calls up web pages over the internet with no problem.
import org.eclipse.swt.browser.Browser;
final Browser browser = new Browser(group01, SWT.NONE);
browser.setBounds(0, 0, 1000, 400);
browser.setVisible(true);
browser.pack();
browser.setUrl(texturl.getText());
I have a C executable which captures and documents network traffic. I communicate with it by entering http://27.0.0.1:6500 into any browser (it works with them all). It responds with a simple html form (three buttons, a tick box, a label, and one text box).However I cannot get it to work with the embedded SWT browser.

I'm and having troubling figuring out how to work some JSF magic on a Relationship that I crated on my database. Here is what I have coded.
My stateless Bean
//..
public void setmoney(Money money)}
em.presist(money);
//..
}
My JSF bean process (moneyJSF.java)
//..
public void addMoney(){
money_bean.setMoney(money_entity);
//..
}
[Code] .....
NOTE: typeJSF in the HTML code just grabs the data from the database in the table called typesOf. Money and types have a many to one relationship.
When I submit the selections, I get the following error:
Conversion Error setting value 'com.serveftp.wigm.entities.Types[ typeOfID=1 ]' for 'null Converter'
I understand that I need to convert from a string object to a Types object using the types entity, however I am not sure where to start on this one.

I have an applet which I want to embed into HTML. In applet viewer in Eclipse IDE the view is this(see pict01), and when I access my index.php on local server I get this view(see pict02). I don't know what I am doing wrong. I checked it with Firefox, IE and chrome. No changes. Here is source code:
import java.util.*;
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.applet.*;
import java.net.URL;
public class WCURL extends JApplet {
//static final int WIDTH = 8;
//static final int HEIGHT = 12;
[Code] ......
I have these files in my local servers folder where I am trying to access it from(see pict03).

Why is my create jar file programatically not working? So doing this does create a jar file. When I run the jar file via command line, it gives me "Could not find or load main class ...". I'm not sure exactly why. I took some code i found here: java - How to use JarOutputStream to create a JAR file? - Stack Overflow and apparently it didn't specify the main class so I specifically added it myself. am i doing something wrong? And btw, the file (that contains all the class files) do not have any directories in them. so it's essentially just one folder with a bunch of class files in there. below is the code.
I had the commons-io-2.4 jar referenced into my build path that can be downloaded here: Commons IO - Download Commons IOreason i guess i added to that, though i'm not sure if it was necessary or not, was because it has a file filter which can tell which files are hidden or not and thing is without it it was adding like DS_STORE(which is hidden and i guess unnecessary) to the jar. not sure if this logic is right but just letting you know.
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileFilter;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.jar.Attributes;

I'm having problems with using the h:inputFile tag with JSF 2.2 and Glassfish 4.0 on Eclipse. The file uploads work when the enctype is set to "multipart/form-data" in the h:form tag, but AJAX will not work. When I leave out the encType (defaults to "application/x-www-form-urlencoded") AJAX works but the uploads do not work, and in fact Glassfish crashes and generates the message:
The request content-type is not a multipart/form-data
Likewise I'm having the same problems with the PrimeFaces file upload tag p:fileUpload. In a JSF 2.0 it works correctly, but with JSF 2.2 it's giving the same problems and generates the message above.
When I start up Eclipse it tells me that Mojarra 2.2.0 is installed. Is this the source of the problem, and if so, how do I install a later version of Mojarra?

Working on a program that creates an array from a file, organizes it in various ways, and then prints the results. Right now I'm specifically having trouble with the printAry() method - when I try to run it, I receive a NullPointerException for the active line in printAry() (EDIT: line 102). Not sure which sections are important to this, so I will include the client class and most of the service. I realize that the amount of documentation I included is not necessary, but it is required for the class.
class Lab3StudentAryService
{
private int count;
private Lab3StudentData [] studentAry = new Lab3StudentData[50];
/*
@param: none
@return: none
reads file and converts to array.
*/
public void fillAry() //constructor

I need to read in a file then create the tables and load in the data from the files to the database. I cant seem to figure out how to load the provided text file into the database.it contains lines like this
Boston Americans,AL,Pittsburgh Pirates
New York Giants,NL,Philadelphia Athletics
etc..
The first line in the field is the name of the team that won in 1903, and the last line is the name of the team that won in 2013. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file
The program should have a menu that has the following options.
NOTE: the data for choices to e) needs to come from running sql statements on the database tables created in choice a). Not from an ArrayList in memory.
a) Convert the baseball text file to a database table. Ask the user from a dialog box, for the location of the text file. This menu item should create the tables and load up the data.
b)Let the user input a team name, and list all of the years that they won the World Series
c)Let the user input a team name, and list the number of times they won the World Series
d)Let the user input a year, and you list the winner and loser for that year.
e)Add a new winner. The user should supply the winning team name, losing team name and year. Make certain that the year does not yet exist in the table and do not duplicate the team name(s) if they are already in the database tables.
f)Exit
I have two tables teams and games:
Drop table if exists game;
Drop table if exists team;
CREATE TABLE IF NOT EXISTS game (
yearGame int(11) NOT NULL,
winTeam int(11) NOT NULL,
lossTeam int(11) NOT NULL,
[Code] ....
I cant figure out how to load the values into the tables as only some of the fields are in the text and and the league field is in a seperate table. Here is my script so far
do {
JFileChooser chooser = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter("Text/Java files", "txt", "java");
chooser.setFileFilter(filter);
int returnVal = chooser.showOpenDialog(null);

We have a custom authorization in our application login page, authorization by using eToken and java (signed jar classes) and applet as login button on page. It's work fine on older and current java versions like 7u67, 7u71 but it's not work on new java version 8u25.
We write a test class named AuthControl without package, we found that problem is in .jar file path, for example:
&APPLET_VERSION. is a jar file name, uploaded using "Shared Components / Static Files - Create"
<script src="https://www.java.com/js/deployJava.js"></script>
<script>
var attributes = {code:'AuthControl',
archive:'#WORKSPACE_IMAGES#&APPLET_VERSION.', width:132, height:37}; // problem in the path to the .jar file
var parameters = { scriptable:true, mode:'login' };
var version = '1.6';
deployJava.runApplet(attributes, parameters, version);
</script>
Error is:
...
java.lang.ClassNotFoundException: AuthControl
at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source)
at sun.plugin2.applet.Plugin2Manager.initAppletAdapter(Unknown Source)
at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
basic: load: class AuthControl not found.
...
But if we use a direct path to the jar file, it's work fine without errors, example:
<script src="https://www.java.com/js/deployJava.js"></script>
<script>
var attributes = {code:'AuthControl',
archive:'http://example.com/myapplet.jar', width:132, height:37};
var parameters = { scriptable:true, mode:'login' };
var version = '1.6';
deployJava.runApplet(attributes, parameters, version);
</script>
Why this is happens on 8 java version?

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 ?
