Need help with a simple application

hi guys, i am doing a school project. i used studio enterprise 8 to create a j2ee application, using mysql as the database. i believe i have installed all the encessary and the classpaths are right.
i coded, build and run the application, but it isnt working...to be sure the database is working, i wrote a simple code just to connect to the database and insert datas. it worked. but when i run the application, everything complied correctly, and when i use cmd to run the test file, it executed with no errors. but the database didnt changed.
can someone guide me along? as there are a few files, i have uploaded it to http://www.comp.nus.edu.sg/~ngjianfe/IRMS.zip
thanks!

hihi, there has been much progression but i am having problem again. i dont know what went wrong also. checked everything i could, including ejb-jar.xml, sun-cmp-mappings.xml, sun-ejb.jar.xml, sun-web.xml, web.xml.
i wrote 3 entity beans, with 3 respective session beans. 2 of them i tested and works perfectly fine. but for the other way, which i have coded the same way, did not work. below is the errors from the server log...

I need help with a VB Application

I need help with building an application and I am on a tight deadline. Below I have included the specifics for what I need the application to do as well as the code that I have completed so far. I am having trouble getting the data input into
the text fields to save to a .txt file. Also, I need validation to ensure that the values entered into the text fields coincide with the field type. I am new to VB so please be gentle. Any help would be appreciated. Thanx
•I need to use the OpenFileDialog and SaveFileDialog in my application.
•Also, I need to use a structure.
1. The application needs to prompt the user to enter the file name on Form_Load.
2. Also, the app needs to use the AppendText method to write the Employee Data to the text file. My project should allow me to write multiple Employee Data to the same text file. The data should be written to the text file in the following format (comma
delimited)
FirstName, MiddleName, LastName, EmployeeNumber, Department, Telephone, Extension, Email
3. The Department dropdown menu DropDownStyle property should be set so that the user cannot enter inputs that are not in the menu.

Need help with a small application

Hi all, I please need help with a small application that I need to do for a homework assignment.
Here is what I need to do:
"Write an application that creates a frame with one button.
Every time the button is clicked, the button must be changed
to a random color."
I already coded a part of the application, but I don't know what to do further.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class ColourButton extends JFrame {
     JButton button = new JButton("Change Colour");
     public ColourButton() {
          super ("Colour Button");
          setSize(250, 150);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          JPanel panel = new JPanel();
          panel.add(button);
          add(panel);
          setVisible(true);
     public static void main(String[] args) {
          ColourButton cb = new ColourButton();
}The thing is I'm not sure what Event Listener I have to implement and use as well as how to get the button to change to a random color everytime the button is clicked.
Can anyone please help me with this.
Thanks.

The listener:

I need help with the Web Application Certificate

Greets,
The title says it all really. I need help with the Web Application Certificate.
I've followed the instructions from here:
https://www.novell.com/documentation....html#b13qz9rn
I can get as far as item 3.c
3. Getting Your Certificate Officially Signed
C. Select the self-signed certificate, then click File > Certification Request > Import CA Reply.
I can get the certificate in to the Filr appliance but from there I'm stuck.
Any help much appreciated.

ok when you have you self signed certificate and you requested an official certificate with the corresponding CSR then you just need to go back to the digital certificates console. To import the official certificate, select the self signed certificate, then click File > Certification Request > Import CA Reply. Then a new windows pops out to select the certificate from your trusted authority from your local hard disk. Find the file (.cer worked for me) and click ok. As soon as you do this in the digital certificates console the self signed certificate will change the information that now it is officially signed. Look at the second column and you should see the name of your trusted authority under "issue from"
I personally had a lot of issues across all platforms. Especially Firefox and Chrome for android. Needed to pack all the root cert, intermediate cert and signed cert into one file and import as CA reply. Not even sure if this is correct now. But at least it works.

Need help with a simple process with FTP Adapter and File Adapter

I am trying out a simple BPEL process that gets a file in opaque mode from a FTP server using a FTP adapter and writes it to the local file system using a File Adapter. However, the file written is always empty (zero bytes). I then tried out the FTPDebatching sample using the same FTP server JNDI name and this work fine surprisingly. I also verified by looking at the FTP server logs that my process actually does hit the FTP server and seems to list the files based on the filtering condition - but it does not issue any GET or RETR commands to actually get the files. I am suspecting that the problem could be in the Receive, Assign or Invoke activities, but I am not able identify what it is.
I can provide additional info such as the contents of my bpel and wsdl files if needed.
Would appreciate if someone can help me with this at the earliest.
Thanks

Need help with a simple basketball game.

Hi im new here and I need help with making this simple basketball game.
Im trying to recreate this game from this video. Im not sure if he is using as2 or as3
Or if anyone could help me make a game like this or direct me to a link on how to do it It would be greatly appreciated.

If you couldn't tell whether it is AS2 or AS3, it is doubtful you can turn it from AS2 into AS3, at least not until you learn both languages. There is no tool made that does it for you.

Im DROWNING! need help with a simple java assignment! plz someone help me!

i need help with my java assignment, with validating a sin number. easy for must who know java. im drowning... please help!

You will need to store each digit of the social insurance number in a field of its own. To validate the entry you will:
1. Multiply the 2nd, 4th, 6th and 8th digit by 2.
2. If the product of any of the four multiplications result in a value greater than 9, add the two resulting digits together to yield a single-digit response. For example 6 * 2 = 12, so you would add the 1 and the 2 to get a result of 3.
3. Add these four calculated values together, along with the 1st, 3rd, 5th, and 7th digits of the original number.
4. Subtract this sum from the next highest multiple of 10.
5. The difference should be equal to the 9th digit, which is considered the check digit.
Example of validating S.I.N. 765932546
1st digit 7
2nd digit (6*2 =12 1+2=) 3
3rd digit 5
4th digit (9*2 = 18 1+8 =) 9
5th digit 3
6th digit (2*2 = 4) 4
7th digit 5
8th digit (4*2 = 8) 8
Total 44 next multiple of 10 is 50
50-44 = 6 which is the 9th digit
Therefore the S.I.N. 765932546 is Valid
********* SIN Validation *********
Welcome - Please enter the first number: 120406780
Second digit value multiplied by 2 4
Fourth digit value multiplied by 2 8
Sixth digit value multiplied by 2 12
Eighth digit value multiplied by 2 16
Value derived from 6th digit 3
Value derived from 8th digit 7
The total is 30
Calculated digit is 10
Check digit must be zero because calculated value is 10
The SIN 120406780 is Valid
this is my assignemtn this is what i have! i dont know where to start! please help me!

Need help with a simple Rename/Join Domain/Install SCCM Client Task Sequence

Good morning everyone,
I need to create a very simple task sequence that will run an .exe that we have created that renames the computer based on a prefix-serialnumber...then restarts, adds it to our domain, restarts, and then installs the SCCM client.
1) run rename program
2) join to domain
3) install sccm client
Can someone help me with the steps that will be required for this?
Thank you very much!
**note, these will not be formatted/have an OS installation ran on it with this task sequence. The situation is that we are receiving 400+ custom configured laptops, and we're going to have to rename/join/install sccm on each...trying to simplify
this
any recommendations are greatly appreciated!

Narcoticoo : Which boot image am i supposed to be using to insure that it boots into Standard Windows, NOT WinPE? I have a standard x86 package / boot image i've been using. If it boots up with this, it goes into WinPE (correct me if I'm wrong,
for this seems to be what happens each time it boots off the boot image...it does not go into windows standard/full)
When I go into properties of the one i'm using, and take the check off of "Use a boot image", where it will not boot to WinPE, it will not even show up in my list of available task sequences for
1) when I PXE boot to try the task sequence, or
2) when I try to make stand-alone media for this task sequence as you have suggested

I need help with some simple code! Please read!

hi everyone.
I'm having problems with a piece of code, and i'd be extremely greatful if somebody could give me a hand with it. I'm totally new to java and have to make a program for my university degree, but i'm finding it extremely difficult, mainly due to my total lack of apptitude for this type of thing. I know this is easy stuff, but the books I have are no use so any help would be greatly appreciated.
I have to write a program which uses two class files. I want one with the code to produce a simple button, and one to invoke it several times at different locations. I decided to write the program as one class file at first, and thought i'd be able to split it up at later. The program works fine when it is one class file. My book said that to split the two classes up, all i needed to do was change the second class to public, although this seems to not work at all. I'm at my wits end on this, and if anyone could correct my code I'd be eternally greatful.
Here is the first class... (sorry about the lack of indentation)
>>>>>>>>>>
import java.awt.*;
import java.applet.Applet;
public class Phone extends Applet {
private Image image;
public void init() {
setLayout(null);
image = getImage(getDocumentBase(), "phone.jpg");}
public void paint (Graphics g) {
g.drawImage(image, 0, 0, 700, 530, this);
PhoneButton myButton;
myButton = new PhoneButton(20,20);
>>>>>>>
This is the second class....
>>>>>>>
public class PhoneButton {
private Button butt;
public PhoneButton(int a, int b, int c){
setLayout(null);
butt = new Button();
butt.setBounds(a,b,20,20);
add(butt);
>>>>>>>>
My compiler generates errors relating to Button, but i can't do anything to please it.
Also, could anyone give me some pointers on how to add a different number or symbol to each button. That is what I added int c for, but i couldn't get it to work.
Cheers in advance.

I found that there are 5 error in your code.
1. You should import the "java.awt" package to the PhoneButton.java
2. The PhoneButton is not a kind of Component. You cannot not add it to the Phone class
3. the myButton = new PhoneButton(20, 20) does not provide enough parameters to create PhoneButton
4. You cannot add a Button to a PhoneButton. Becaue the PhoneButton is not a kind of Container
Fixed code:
import java.awt.*;
public class PhoneButton extends Button {
public PhoneButton(int a, int b, int c){
setBounds(a, b, 20, 20);
setLabel(String.valueOf(c));
===========================================
import java.awt.*;
import java.applet.Applet;

Need help with BC4J/Struts application using a Stored Procedure

Hi,
I am doing a proof of concept for a new project using JDeveloper, Struts and BC4J. We want to reuse our Business logic that is currently residing in Oracle Stored Procedures. I previously created a BC4J Entity Object based on a stored procedure Using Oracle Stored Procedures but this stored procedure is a bit different in that it returns a ref cursor as one of the paramters. http://radio.weblogs.com/0118231/stories/2003/03/03/gettingAViewObjectsResultRowsFromARefCursor.html
I tried the above method, but I am having some trouble with it. I keep getting the error ORA-01008: not all variables are bound when I test it using the AppModule tester.
Here is the store procedure definition:
CREATE OR REPLACE PACKAGE pprs_test_wrappers IS
TYPE sn_srch_results IS REF CURSOR;
PROCEDURE sn_srch_main_test
(serial_num_in IN OUT VARCHAR2
,serial_coll_cd_in IN OUT NUMBER
,max_rows_allowed IN OUT NUMBER
,total_rows_selected IN OUT NUMBER
,message_cd_out IN OUT VARCHAR2
,query_results OUT sn_srch_results
END pprs_test_wrappers;

I created the view object in expert mode so there is no entity object. Can someone help? I don't have much time left to finish this.
Also, could I have done this from the Entity object instead of the view object by registering the ref cursor OUT parameter in handleStoredProcInsert()?
Thanks

I was able to get the input parameter by putting the following in my struts actions class
vo.setWhereClauseParam(0,request.getParameter("row0_SerialNum"));
The full code is:
package mypackage2;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import oracle.jbo.html.BC4JContext;
import oracle.jbo.ViewObject;
import oracle.jbo.html.struts11.BC4JUtils;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class LienCheckView1QueryAction extends Action
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
BC4JContext context = BC4JContext.getContext(request);
// Retrieve the view object instance to work with by name
ViewObject vo = context.getApplicationModule().findViewObject("LienCheckView1");
vo.setRangeSize(3);
vo.setIterMode(ViewObject.ITER_MODE_LAST_PAGE_PARTIAL);
// Do any additional VO setup here (e.g. setting bind parameter values)
vo.setWhereClauseParam(0,request.getParameter("row0_SerialNum"));
// default value for serialCollCd 1 is for Motor Vehicles
vo.setWhereClauseParam(1,new oracle.jbo.domain.Number(1));
// Default value for maxRows_allowed
vo.setWhereClauseParam(2,new oracle.jbo.domain.Number(20));
return BC4JUtils.getForwardFromContext(context, mapping);
This doesn't always work properly though. The first time I press the query button, the SerialNum parameter is still null, however if I re-execute the query by pressing the query button again. It will work, and return the rows. I always have to query twice. Also the SerialNum attribute is set to a String in my view object, it is a varchar column in the database, but some serial number I enter give a "Error Message: oracle.jbo.domain.Number ". This happens even though the underlying BC4J is returning values for the query. I also get a "500 Internal Server Error java.lang.ClassCastException: java.lang.String on my View object's code at line 65 which is
if (params.length>1) serialCollCdIn = (BigDecimal)params[1];
This is an input paramter to the oracle stored procedure that defaults to a Number value of 1.
Any idea what the problem is? Here is the full code for my view object:

(Click and move to next scene). Need help with a simple action, just need a little guidance.

I am building a simple flash movie clip in Flash cs4. All I want to do is run the play head through a one 5 frame scene and stop, and then you press a button that will send the play head to the next 10 frame motion tween scene.
When I run the movie all I get is a movie clip that pauses for a millisecond then loops back around.
I have three different books on flash action script, read all three still not doing so hot. I am using the navigational button concept maybe that is what I am doing wrong. Can someone show me the right method or lead me in the right direction.

You can just place an invisible button on the top layer of
the flash time line and code it to getURL. When you said "hyperlink
to another page", are you referring to an html page or another swf
file? To make an invisible button in Flash, you can hit Ctrl+F8 to
bring up the dialog box to create a new symbol, name your button,
make sure you select the type of button, hit ok, now you are inside
the button and need to create a "hit" area. Click on the "hit"
state and press F7 to create a blank key frame. Using the drawing
tools, select the square, no stroke, and any fill color you want,
draw a square shape, click on the shape and in your Info Panel,
change the size of this shape to match the size of your stage,
lastly, make sure the registration point is (0,0) by using the
Align Panel. Go back to your main time line, add a layer on your
time line and make sure it's at the top, drag your new button from
the library to the stage and align it to (0,0).
There are two ways to code the button, so to make it easier,
click on the button once to select it, hit F9 to bring up the
actions panel and type this
on(release){
getURL("
http://www.someWebsite.com",
"_blank");// you can also use "_self" //
If some of this isn't new to you, disregard parts of it. If
you have any buttons in your Flash application, this will cause
problems because the invisible button will counter-act anything
below it. Let me know if this works for you. Of course, this all
assumes you have access to the flash file.

I need help with a simple task (PLEASE HELP)

hi, you know how you can make a button and link it to a
different site with the actionscript in this program? well I need
to know of a way like...to make a button and...link it to the next
frame. ok, heres what im trying to make happen...the user presses a
button in the flash program thing and a comment apperars. then they
press it another time and a new one come up...and so on...I could
make like 50 different frames with new comments on them and then
make the button on each frame link to the next frame. is there a
way to do that? if there is I REALLY need your help. please
thanks :)

no need to modify anything - look at the first code:
on (release) {
nextFrame();
that's all you need on the button.
If you want it to happen on click and not release:
on (press) {
nextFrame();

Need help with a simple php page link

I have a small .php to force the download of a file when a user clicks on a link:
<?php
header ("Content-type:application/pdf");
header ("Content-Disposition:attachment;filename='form.pdf'");
readfile ("form.pdf");
?>
I need to include code which will redirect the user back to the home page without opening a new browser window, either during or immediately after downloading the file. And if it's possible, prevent the browser back button to return the user to the download page.
I tried adding this after the readfile line: echo "<a href="mywebsite.com/index.html" /a>";
but that failed miserably. My php knowledge is as weak as a bull moose after the mating season. Can someone help me out on this?

If you couldn't tell whether it is AS2 or AS3, it is doubtful you can turn it from AS2 into AS3, at least not until you learn both languages. There is no tool made that does it for you.
