Need help on packaging an application

Hi,
Can anyone please guide me in packaging an application? On trying to create the installation scripts, I am not sure how to add the database objects to it.
Thanks in advance.
Regards,
Annie

Hi Varad,
That problem is resolved. I could not add all DDL statements in a single installation script. But things worked fine on creatin separate ones.
But I have one more query. In addition to installing the database objects, how can I also copy the data to another instance?

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.

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.

Help With "Package An Application" Using APEX 3.0.1 with XE

I'm using apex 3.0.1 and XE Database and I'm trying to create a package application but without succes, I can find the way to do it and I know that it's possible. What I'm trying to do is create a file like the package application that we can download from Oracle page but for an application I create.
Looking here in the forums I found this link:
http://www.oracle.com/technology/oramag/oracle/06-jul/o46browser.html
And I was trying to follow it step by step until I found the Step 4: Package Up the Application, number 7.
1. In the breadcrumb links in the upper left-hand corner of the screen, click the Application nnn link (where nnn corresponds to the ID of the employee lookup application in your Oracle Application Express instance).
2. Click the Edit Attributes icon, and then click Supporting Objects.
3. Click Edit.
4. In the Welcome section, enter readme text for the application in the Message field, such as "This application lets users browse employee information. Users accessing the application with a USERID stored in the table can upload a photo if one does not already exist."
5. Click the right arrow to go to the Prerequisites tab.
6. To ensure that folks who already have a table named OM_EMPLOYEES in their schemas don't run into a conflict with this script, enter OM_EMPLOYEES in the first Object Names field and click Add.
[b]7. Click the Scripts tab.
8. Click Create.
9. Click the Copy from SQL Script Repository icon.
10. Enter Create Table, Sequence, and Trigger in the Name field, and click Next.
11. Select om_employees.sql, and click Create Script.
12. Repeat steps 9 through 11 for the om_download_pict.sql and seed_data .sql scripts. Feel free to name these scripts as you see fit.
13. Click the Deinstall tab, and click Create.
14. Click the Create from File icon.
15. Click Browse, select the drop_om_objects.sql script (included with this column's download file), click Open, and click Create Script.
16. Click the right arrow.
17. Select Yes for Include Supporting Object Definitions in Export.
18. Click Apply Changes.
I can't find the scrips tab and I completely lost. I start to believe that this steps don't apply for Apex 3.0.1.
If anyone of you could help me with this, please do it, I really need it.
Johann.

Johann,
That doc was probably written against 2.2 because in 3.0, we reworked the supporting objects page a bit. If you are on Supporting Objects, in the Installation region, click on Installation Scripts. For more information, check the Advanced Tutorials document off our OTN site for a Tutorial called Reviewing a Packaged App (something like that - I can't access the doc at the moment).

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:

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
Natalie

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:

Need help in creating WEB application....

Hi
I Created WEB application using jsp,java classes.
I kept All jsp files and classes in web-inf classes folder and created a war file and deployed that one in WEBLOGIC 7.0. I need to start a class while starting the server. I configured the startup classes using weblogic console.Now i am getting classnotfound exception while running the server saying that the startup class is not found. Is it necessay to set classpath to the classes which are under war file.If yes please give me an idea how to set classpath to a file which is under war/web-inf/classes/..
Any help will be appreciated.
Regards
Anand Mohan

Not sure about Weblogic, but in general you add the entire path to your classpath. For Windows 2000 servers -> Control Panel -> System -> Advanced Tab -> Env Variables
Example from simle Tomcat install:
CLASSPATH
C:\Jakarta\jakarta-tomcat-4.1.18\common\lib\servlet.jar;C:\Jakarta\jakarta-tomcat-4.1.18\webapps\myApp\WEB-INF\lib\classes12.jar;C:\Jakarta\jakarta-tomcat-4.1.18\webapps\myApp\WEB-INF\classes\com\brainysoftware\java\StringUtil.jar

Need help for Visual Web application onkeydown event

hi,
I have create a visual web application. I have include a text field and a button in my webpage. When user press a key in the text field, i would like to change the button to enable. I try to use the keydown event to call the function in java package. However, it display error once I put the function name in my onkeydown event in jsp page. The code is shown as below.
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root version="1.2" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:webuijsf="http://www.sun.com/webui/webuijsf">
<jsp:directive.page contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"/>

<webuijsf:link binding="#{RegisterProgress.link1}" id="link1" url="/resources/stylesheet.css"/>
</webuijsf:head>
<webuijsf:body binding="#{RegisterProgress.body1}" focus="form1:txtPassword1" id="body1" style="-rave-layout: grid">
<webuijsf:form binding="#{RegisterProgress.form1}" id="form1">
<webuijsf:button actionExpression="#{RegisterProgress.button1_action}" binding="#{RegisterProgress.button1}" id="button1"
style="left: 71px; top: 96px; position: absolute; width: 72px" text="Next"/>
<webuijsf:textField binding="#{RegisterProgress.txtPassword1}" id="txtPassword1" label="Password :" onKeyDown="="#{RegisterProgress.keydown}" style="left: 24px; top: 48px; position: absolute"/>
</webuijsf:form>
</webuijsf:body>
</webuijsf:html>
</webuijsf:page>
</f:view>
</jsp:root>
Is there anybody may teach me the way to invoke the keydown event?

Sorry,
onKeyDown="="#{RegisterProgress.keydown}"
should be onKeyDown=#{RegisterProgress.keydown}"
But, that onkeyDown still can't work.
Below is my java package:
package usm_biologin;
import com.sun.rave.web.ui.appbase.AbstractPageBean;
import com.sun.webui.jsf.component.Body;
import com.sun.webui.jsf.component.Button;

Need help in Publishing the application URL

hi,
I am using Aoolication Express 3.0. I need to publish the URL of my application, so that both the database and application can be accessed from any computer using the URL.
Can anyone help me with that.
Thank you in advance.

I read yesterday (from the advanced tutorial documentation):
"You can determine the URL to your application by positioning the mouse over the RUN icon on the Application home page. The URL appears in the status bar at the bottom of the page."
It works.

Need Help for AIR Email Application

Hi,
I’m a beginner to Adobe AIR.
My new assignment is to create an AIR Application which works like MS Outlook with minimal features like compose mail, inbox, send items and contact details.
With the help of some server side script (like PHP, CF) I can make it work. But My TL asked me to communicate directly with mail server through AIR.
I googled for a week for some tutorial to help me, But I can’t find anything useful.
Is there any way to communicate directly with web server and list the Inbox, Outbox, and Contact details…? If so, please help me to find the solution…
Thanks In Advance

Hi,
You can use LaunchExecutableEx to determine the window state:
LaunchExecutableEx ("command.com /C calc.exe", LE_HIDE, NULL);
Beware that this function does not wait for the started executable to exit.
It executes the command in the string and continues.
If your application has to get the results of the call, then you need to get the application handle (3rd parameter, put a variable instead of the NULL above) and call ExecutableHasTerminated in a loop to find out if the execution finished.
Read carefully the help for the LaunchExecutableEx function and Handle parameter.
To get the result of the command line call, you can add a "> output.txt" parameter to the end of your command line call.
This way all the text output of the command is written to the output.txt file, from which you can read the result.
Check the command-line email sender program's help if there is a special paramter to make it more "verbose".
Hope this helps,

Begginer needing help with "package" word

Hi,
I'm a Java newbie and I'm trying to get comfortable with programming in Java on my Mac (running Mac OS 10.3).
I found some sample code that I'm testing out at:
http://www.macdevcenter.com/pub/a/mac/2001/08/03/osx_java.html?page=1
but I'm having problems using the reserved word "package".
at the time of each .java file the sample code has:
package NineSquares;When I compile this in the Terminal window using the command
javac NineSquares.java
javac MainFrame.java
javac EachSquare.javaI get the following error message:
NineSquares.java:8: cannot resolve symbol
symbol : class MainFrame
location: class NineSquares.NineSquares
new MainFrame();
^
1 error
David-Salvays-Computer:~/introcs/Project2 davidsalvay$
when I comment out the package line it compiles fine.
I don't understand what package means and how I use it. BTW, all my .java files are in the same folder and I've already set the classpath to the file containing my main method (NineSquares.java).
Any help/suggestions/ideas will be much appreciated!
--David

1. package is always declared first in a class definition.
2. If you've got a class foobar, and that class is in package x.y.z, then the .class file needs to be in a file foobar.class under the directory hierarchy x\y\z\foobar.class, and where the directory above x is in the classpath.
3. The official name of that class is x.y.z.foobar. You can import it using import x.y.z.*; or import x.y.z.foobar; Import just lets you use the class without having to always write x.y.z
