SQLJ/JDBC code compiles but doesn't run

I keep getting a fatal error in the JAVA.EXE module when I try to run an code with SQLJ/JDBC. I've got my class and classpath set up like a oracle support tech told me to do but the code still bombs.
I noticed java.exe bombs at the same address no matter what SQLJ/JDBC code I compile.
Could it be conflicting with something on
a NT 4.0 box.
Anyone with ideas please respond.

Can you run a non Oracle Java application. Which version of JDK are you using.. do you have multiple versions of JDK .. if so make sure there is no conflict.. You may try re-installing the JDK if your non Oracle Java application also errors out..

Stumped with SwingWorker -- code compiles but doesn't run right

Okay, sorry to post a ton of code, but I'm creating a swing gui that will use swing worker to create an object of the followng class, one method that sleeps and returns a random number:
public class BigJob{
     public int doBigJob(){
          try {
          Thread.sleep(15000);
          } catch (InterruptedException e){
          e.printStackTrace();
     int number = (int)(Math.random() * 50);
     return number;
}I can get the gui program below to run without the SwingWorker, but am having trouble getting it to run properly. The code posted below compiles and starts up ok, but when I click the "click to do big job" button, it just doesn't do anything.
I created a runnable in the main method, and invoked the method to build the gui, so that's working.
I have the SwingWorker defined in an inner class that implements ActionListener; I'm guessing that's the problem. I should probably put the SwingWorkder in its own inner class, and invoke it from the first listener class?
here's the code:
import javax.swing.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import java.awt.BorderLayout;
import javax.swing.SwingWorker;
public class WorkerTest{
     private JFrame frame;
     private JButton button1;
     private JButton button2;
     private JButton button3;
     private JPanel topPanel;
     public static void main (String[] args){
     SwingUtilities.invokeLater(new Runnable() {
          public void run(){
          WorkerTest wtest = new WorkerTest();
          wtest.buildGui();
     } // end main
     public void buildGui(){
     frame = new JFrame("frame to test swing worker");
     frame.setSize(700,200);
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     frame.setLayout(new BorderLayout());
     topPanel = new JPanel();
     frame.add(topPanel, BorderLayout.NORTH);
     button1 = new JButton("click to change text");
     button1.addActionListener(new Button1Listener());
     button2 = new JButton("click to do big thing");
     button1.addActionListener(new Button2Listener());
     button3 = new JButton("click to change text");
     button3.addActionListener(new Button3Listener());
     topPanel.add(button1);
     topPanel.add(button2);
     topPanel.add(button3);
     frame.setVisible(true);
// inner classes to add listeners
     class Button1Listener implements ActionListener{
          public void actionPerformed(ActionEvent e){
          button1.setText("i've been clicked");
     class Button2Listener implements ActionListener{
          public void actionPerformed(ActionEvent e){
          // execute job in main thread
          //BigJob job = new BigJob();
          //button2.setText("big job is done: " + job.doBigJob());
          // execute job in its own thread:
          SwingWorker worker = new SwingWorker<BigJob, Void>(){
          BigJob job;
          int resultNum;
               public BigJob doInBackground(){
               job = new BigJob();
               resultNum = job.doBigJob();
               button2.setText("big job done: " + resultNum);
               return job;
     class Button3Listener implements ActionListener{
          public void actionPerformed(ActionEvent e){
          button3.setText("i've been clicked also");
} // end WorkerTestthanks,

One has to initialise a session first for use with Oracle Apps if you want to make it run as a concurrent job.
Any decleration within your package will not be recognised unless initialisation is sucessful.
Investigate the built-in packages:
FND_GLOBAL - for initialisation
FND_SUBMIT - for setting session relevant parameters
-- function returns true or false depending on whether the initialisation was sucessful or not
create or replace function is_Init_OK (p_User_Name       in varchar2
                                      ,p_Responsibility in varchar2
                                      ,p_Language        in varchar2) return boolean as
b_Set_NLS   boolean;
b_Set_Mode boolean;
r_ISet      fnd_Init := Get_Init_Set(p_User_Name, p_Responsibility);
begin
    -- 1
    fnd_global.apps_initialize(r_ISet.User_ID, r_ISet.Resp_ID, r_ISet.App_ID);
    -- 2
    b_Set_NLS := fnd_submit.set_nls_options(p_Language);
    -- 3
    b_Set_Mode := fnd_submit.set_mode (false);
    return (b_Set_Mode and b_Set_NLS and (    (r_ISet.Resp_ID is not null)
                                          and (r_ISet.User_ID is not null)
    exception
      when others then
        return false;
end is_Init_OK;
-- for example
declare
l_User_ID number = 'IMPORT_POST'; --- import post user
l_Resp    number = 'Import and Posting responsibility' -- import posting responsibility
l_Language varchar2(100) := 'AMERICAN';

Compiles, but doesn't run - also objects used like arrays?

Hello. I am a way newbie at Java, but I like it a lot. I'm using it to write a little final project for an intro CS class I'm taking. The program is a little mileage calcuator. Okay, so here's what I don't get. I started to write out the program and everything was compiling, my output and input were working. Then I started to add some classes and objects. Now it still compiles, but the command line just gives me "hit any key". None of my output or input stuff. What happened?
While I'm at it, in C++ I would've used a little array to store a bit of data for this app. Can I use multile objects of a class and iterate through them in a for each in the same way?
Any help much appreciated.
Here's the code:
//Joanna Grossman
//mileage calculator
//final project SWE 150
//creates vehicle class
class vehicle {
     int id;
     String name;
     int mpg;
//creates different vehicle objects - may need to be changed to array
class vehicleTypes {
     public static void main(String args[]) {
          vehicle SUV = new vehicle();
          vehicle hybrid = new vehicle();
          vehicle FordTaurus = new vehicle();
          //assigns values for cars
          SUV.id = 1;
          SUV.name = "SUV";
          SUV.mpg = 10;
          hybrid.id = 2;
          hybrid.name = "Honda Civic";
          hybrid.mpg = 50;
          FordTaurus.id = 3;
          FordTaurus.name = "Ford Taurus";
          FordTaurus.mpg = 23;
//creates location class
class location {
     int id;
     String name;
     int miles2Loc1;
     int miles2Loc2;
     int miles2Loc3;
//creates location objects
class locationObjects {
     public static void main(String args[]) {
          location Burlington = new location();
          location NewYork = new location();
          location Syracuse = new location();
          //assigns values to locations
          Burlington.id = 1;
          NewYork.id=2;
          Syracuse.id = 3;
          Burlington.name = "Burlington";
          Burlington.miles2Loc1 = 0;
          Burlington.miles2Loc2 = 308;
          Burlington.miles2Loc3 = 270;
          NewYork.name = "New York";
          NewYork.miles2Loc1 = 308;
          NewYork.miles2Loc2 = 0;
          NewYork.miles2Loc3 = 246;
          Syracuse.name = "Syracuse";
          Syracuse.miles2Loc1 = 270;
          Syracuse.miles2Loc2 = 246;
          Syracuse.miles2Loc3 = 0;
//mainline logic
class mileageCalculator {
     public static void main(String args[])
          throws java.io.IOException {
          char play;
          play='y';
               System.out.println("Would you like to calculate your mileage?");
               System.out.println("Please press \"y\" for \'yes\' or \"n\" for \'no\'\nThen Press \"Enter\"");
               play = (char) System.in.read();
               System.out.println("Your answer is "+play);
               System.out.println("What is your destination?");
               System.out.println("Press press it's number:");
               System.out.println("1\tBurlington\n2\tNew York\n3\tSyracuse");
}

You're probably "running" one of the classes that doesn't produce any output. The main() method is intended to be an application's entry point, not someplace you just cram all your code. You'll want to learn about methods and how objects communicate with each other. Have a look at the following:

Old C socket program compiles, but doesn't run properly

I have an old C program that uses sys/ipc.h to listen on ports 6666 and ports 6669 for user requests. I have determined that the
program gets to the 'accept' call without error. The return from accept(sockfd, (struct sockaddr *) &cli_addr, &cli_addrlen) is zero
indicating success. Nevertheless, something is wrong, because netstat -a shows nothing listening on either 6666 or 6669, and
telnet to these two ports fails as well.
I've compiled and run the program on Sparc 8 and 9. It is the i86pc architecture I am having a problem with. I tried having root
run it in the global zone in order to eliminate zones as a factor with no success.
This program also uses threads (thread.h) and rpc (rpc.h). Has anyone seen this problem? Does anyone have a suggestion?
George

Hi Darren:
Thanks for your prompt supply. I saw no alternative but to start pulling the code apart and I believe I have a solution. I think big-endian as opposed to
little-endian definitely has something to do with it.
Here's what I had to change to make this work:
Original Code: serv_addr.sin_port = htonl(port);
Modified Code: serv_addr.sin_port = htons((short) port);
Converting the port to a short seems to have fixed things. The original code converted the port to a long.

Java 1.5_16 Compiles my programs but doesn't Run?

I am using Dr Java and I have a lot of old programs that I would like to run.
I had to start over and re-download the Java JDK. I tried 1.6.7 but I got an error that it couldn't
locate the source, so I went back to Java 1.5.16, which was the oldest version I could find on java.,
and now my programs are compiling but when I run them, I get a message in the bottom bar
"Running Main method of Current Document" and nothing happens (even after a few minutes).
This is happening on very simple small programs that should run instantly.
It is happening for all of the old programs that I am able to compile.
I think I was using JDK 1.5.6 when I first wrote these programs.
Any suggestions?
Thanks,
Jesi

You're probably "running" one of the classes that doesn't produce any output. The main() method is intended to be an application's entry point, not someplace you just cram all your code. You'll want to learn about methods and how objects communicate with each other. Have a look at the following:
The Java� Tutorial - Trail: Learning the Java Language
Good luck!

Program compiles, but does not run

Subject: Program compiles, but does not run
I am trying to port a Java application from the PC to the Mac. I am using XCode and the program compiles, but it does not run.
When I try to run the ...app, I get the message that the main class is not specified, etc.

I do specify the main class in both, the Manifest file and the Info.plist file, in the correct way, "package.MainClass". Is there another place where I need to specify it?
Why do I need org/bouncycastle/asn1/DEREnumerated.class, and how would I have to specify it in Manifest?
I also posted these questions at Mac Programming at forums.macrumors.com and at Xcode-users Mailing List at lists.apple.com/mailman/listinfo, but I did not get any answer.
Please help! Thanks!

There was something wrong with my Info.plist file.
So, here is my corrected Info.plist file:

Also, in the Run menu of my XCode project, Go, Run, and Debug are disabled, but perhaps this has to do with not being able to run the AnanyaCurves.app file.

ok the array problem is fixed i was having a simple "one off" mistake when accessing the array.
As for the error that i keep getting. I honestly can't see where the problem with this is in code.
The it cant be equalt to nothing because this is written so that it has to equal a letter before the program actually runs through everything. Thanks again for the help
here is the error that i am getting when the program runs.

Program with generics compiles without -source 1.5 but doesn't run.

This could probably be considered a bug in J2SE1.5 beta 1.
A program with generics that is compiled with JDK 1.5 beta1 without the "-source 1.5" option behaves oddly: it compiles but sometimes fails to execute. It shouldn't behave like that. It should fail in the compilation, with a complaint about using the wrong version of the language.
This odd behaviour doesn't always occur! In the small program below, I get that behaviour when using the EnumSet.range method.
If I only use the basic EnumSet, it does executes.
-- Lars
import java.util.EnumSet;
import java.util.*;
public class Example {
     public enum Season { WINTER, SPRING, SUMMER, FALL }
     public static EnumSet<Season> warmSeason = EnumSet.range(Season.SPRING, Season.FALL);
     public static void main(String[] args) {
          System.out.println("Season: ");
          for (Season s : Season.values()) {
          System.out.println(s);
          System.out.println("Cold Season: ");
          for (Season s : warmSeason) {
          System.out.println(s);

Exception in thread "main" java.lang.NoClassDefFoundError: StdInThat means that you are using a class (StdIn), that is not on your classpath, but in some other place.
The "-cp ." tells Java to ignore the CLASSPATH variable and just look in the current directory instead. You probably had the location of StdIn on your CLASSPATH variable.
What you need to do in this case is to add the current directory "." to your CLASSPATH variable.

Trial version of Photoshop Elements 9 installed but doesn't run.

I recently installed Photoshop Elements 9 on computer running Windows 7 and it installed correctly. When I try to run edit or organzer the flashing bar starts but neither program runs. Adobe support wouldn't help since it was a trial version. Any suggestions?

Try making a direct desktop icon for the Organizer and see if you can launch the program directly from the desktop.
On Windows right click anywhere on the desktop and select New >> Shortcut
Browse to Computer OS C:
And find the PSE Organizer application in Program Files or Program Files (x86) on Windows 7 - 64 bit.
Inside the Adobe >> Photoshop Elements Organizer (yellow folder) you are looking for an application file “PhotoshopEementsOrganizer” with six small icons (e.g. representing thumbnails)
Select it and click OK
Click next
Rename by taking out Photoshop Elements leaving just the word Organizer
Then click finish
You should now be able to launch directly form the desktop by double clicking on the icon.
You can set up a similar direct link to the Editor application (.exe file which has the blue PSE icon). As before take out Photoshop Elements just leaving the description Editor and it will show up clearly on the desktop.
It often helps if you right click on a desktop icon and choose “Run As administrator”

Is this a problem with openjdk6-1.5-4-x86_64 or..?

jre provides java-runtime, so commenting out that dependency should not be needed. BTW, I can confirm that jalbum does not work on x86_64 with openjdk6.
Sorry I should read things more carefully! java-environment should be replaced by java-runtime. Only that is needed to run jalbum. And in fact it must be sun's jre, because with openjdk6 ther are the before mentioned problems
Without the change in PKGBUILD you would have to install jdk too.
This is what is happening: jre provides only java-runtime. jalbum with depends=('java-environment') in its PKGBUILD forces you to have either jdk or openjdk6 installed, since these are the packages that provide java-environment. So pacman searches for that. Most if not people have [extra] before [community] in their pacman.conf, so the first thing that pacman finds and that provides java-environment is openjdk6.
Also installing jdk before installing jalbum would do the trick. But jalbum does not really need it.
