How to change property file contents during run time?

Hi everyone. First post so go easy on me please.
I have a couple of properties that I want to read from a from a file. To achieve this I simply use:
ResourceBundle.getBundle("my.package.MyItems").getString("MyProperty");
This works like a wonder. The problem is, i want to change the property "MyProperty" during runtime. I've found the properties file (MyItems.properties) inside weblogic, but if a change its contents it does not reflect in the application.
I can come up with a couple of justifications:
* I'm not looking in the right folder/changing the wrong file in the server;
* Weblogic caches the properties file, meaning that I have to redeploy the project (defeating the purpose of actually having a properties file).
Can anyone help with this one?
[EDIT] Forgot important info:
* JDeveloper 11.1.1.4
* Weblogic 11.3 (not 100% sure)
* Both JDev and WebLogic running on Windows 7 64 bits
Thank you in advance!
Best Regards

JDeveloper 11.1.1.4, not 3

I tried it all.
Just an explanation of my context.
I have 1 application with 2 projects in it. First project is called "CommonUI_ViewController" and the second one "FO_ViewController".
The properties file I'm trying to change is located inside "CommonUI_ViewController", in package "PropertiesConfig" and the file is called "PhaseListener.properties".
"FO_ViewController" is dependent on "CommonUI_ViewController". When I run "FO_ViewController" the integrated weblogic server log shows this (among other things):
[10:25:55 AM] Wrote Web Application Module to D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\FO_ViewControllerWebApp.war
[10:25:57 AM] Wrote Web Application Module to D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\CommonUI_ViewControllerWebApp.war
Note: both lines above point to folders. "FO_ViewControllerWebApp.war" and "CommonUI_ViewControllerWebApp.war" are NOT war files, but folders that have that name.
I tried changing the properties file in the following locations:
* D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\FO_ViewControllerWebApp.war\WEB-INF\lib\adflibSPVCommonUI.jar > PropertiesConfig\PhaseListener.properties;
* D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\CommonUI_ViewControllerWebApp.war\WEB-INF\lib\adflibSPVCommonUI.jar > PropertiesConfig\PhaseListener.properties;
* D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\CommonUI_ViewControllerWebApp.war\WEB-INF\classes\PropertiesConfig\PhaseListener.properties (no need to open any jar/war to get to this one).
I changed all these files with different values but no change was shown in the application (using the method in the previous post).
I believe that I'm still doing something wrong :/
Thank you for your help so far vinod_t_krishnan!

How to hide the Parameter field during Run time?

Hi,
How to hide the Parameter field during Run time?
I have a parameter field which behaves differently depending on the User logged in.
I am using reports 10G
For ex: I have 3 field created in JSP
CUSTOMER
PROVIDER
FROM DATE
END DATE
If the user = 'SUPER show all the parameter
CUSTOMER
PROVIDER
FROM DATE
END DATE
If the user is 'GATEKEEPER" Just show
PROVIDER
FROM DATE
END DATE
Can I do that?
Please help
Thanks.
KK

hi, i'm not familiar much with JSP. but i think workaround is to create two window one which have 4 fields and the other which have 3. if user is SUPER then call the first screen otherwise if user is GATEKEEPER then call the second screen.

How to change the view criteria at run time for af:query

Hi,
I've a usecase where I need to change the view criteria of the af:query at run time.
Use case:
=======
1) Consider a check box (Show Emps Under Dept 10) in the query panel when user selects and clicks 'Search' button should show the employees under dept 10. If user searches without selecting the check box, the results should show all the employees in all the departments.
2) I need to have a check box always in the query panel. Its mandatory.
The way I implemented:
==============
1) Created a transient variable 'Show Emps Under Dept 10' in the EmployeeVO and also created a bind variable bind_DeptNo.
2) Create a view criteria 'AllEmployees' which has only the transient attribute as the view criteria item and whose value set to 'false' by default.
3) Created another view criteria 'EmpUnderDept' which has 'DepartmentId' as the view criteria item and whose value set to the bind variable 'bind_DeptNo'.
4) Dropped the view criteria 'EmpUnderDept' as the 'af:query' panel in the jspx page.
5) Overridden the queryListener as '#{EmpBean.empSearch}'
6) Has the below code in the empSearch method as below. When user selects the check box, applying the other criteria 'EmpUnderDept' and setting the bind variable to '10'.
public void empSearch(QueryEvent queryEvent) {
// Add event code here...
QueryDescriptor queryDesc = (QueryDescriptor) queryEvent.getDescriptor();
ConjunctionCriterion conCrit = queryDesc.getConjunctionCriterion();
List<Criterion> criterionList = conCrit.getCriterionList();
List criterionValues = new ArrayList();
Object criteriaValue = null;
int criteriaNo = 0;
DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
FacesContext facesContext = FacesContext.getCurrentInstance();
for (Criterion criterion : criterionList) {
AttributeDescriptor attrDescriptor = ((AttributeCriterion)criterion).getAttribute();
System.out.println("============== attrDescriptor.getName() =================== " + attrDescriptor.getName());
criteriaValue = ((AttributeCriterion)criterion).getValues().get(0);
if(criteriaNo==0) {
Boolean val = (Boolean) ((AttributeCriterion)criterion).getValues().get(0);
if (val.equals(true)) {
OperationBinding method = (OperationBinding) ADFUtil.findOperation("ExecuteWithParams");
if(method!=null) {
Map params = method.getParamsMap();
//params.put(key, value)
method.getParamsMap().put("bind_DeptId", 10L);
method.execute();
ADFUtil.invokeMethodExpression( "#{bindings.EmpUnderDeptCriteiaQuery.processQuery}", queryEvent);
} else {
//ADFUtil.invokeEL("#{bindings.ExecuteWithParams.execute}");
ADFUtil.invokeMethodExpression( "#{bindings.AllEmployeesCriteriaQuery.processQuery}", queryEvent);
But this approach is not working and its always showing all the employees in all the departments.
Please let me know if there is a way to change the view criteria at run time depending on the values set at run time for one of the view criteria items.
JDev version am using is '11.1.1.5'
Thanks,
Lakshman

Hi Shay,
It worked for me without overriding the executeQuery() method in the ViewImpl.java.
Instead of creating 2 view criteria, I created only one which has both transient variable and the DepartmentId = <bind_DeptId>. With the above code, it worked properly. Now I am using only one view criteria.
Thank you.

How to Hide the Parameter field at run time....

Hi,
I have a parameter field which behaves differently depending on the User logged in.
It has the LOV coming from following SQL.
SELECT customer_name FROM Cust_mast;
If the user = 'INTERNAL' then the Where clause will be
WHERE cust_id in('DELL', 'SBC', 'BANK')
Else there will be no WHERE clause or the parameter field
should be hidden in the parameter form.
So my questions are:
1) How to hide the Parameter field during Run time?
OR OR OR
2) How to change the LOV select statement during Run time?
Thanks.
Ram.

Hi Ram,
Is there any way to play with the sql query SELECT using DECODE ?I'm not sure of this part, maybe someone else can suggest a way.
However, what you want can be done in 2 other ways:
1. Build 2 reports. Both reports will just be duplicates of each other, only difference being that the 'LoV where clause' will be different. Now you can fire the appropriate report in many ways. For example, if the customer is alreay logged inside your custom application, and therefore you already know whether the user is internal of external, you can design your button or link which launches the report to contain logic such that one of the 2 reports is fired depending on who the user is.
1. Use a JSP parameter form, not a paper parameter form In this case, just build an HTML parameter form in the web source of your report. Use Java logic to populate the LoV drop-down list. When you have to launch the final report, just launch the paper-layout of the report. For example (you will have to modify this):
<form action="http://machine:port/reports/rwservlet?report=ParamForm.jsp+..." name="First" method="post">
<select name="selected_customer" onChange="First.submit()" >
<option value="">Choose a Customer Name
<rw:foreach id="G_cust_id" src="G_cust_id">
<rw:getValue id="myCustId" src="CUSTOMER_ID"/>
<rw:getValue id="myCustName" src="CUSTOMER_NAME"/>
<option value="<%=myCustId%>"><%=myCustName%>
</rw:foreach>
</select>
</form>
In the code above, you will have to make sure that your report's data model defines 2 CUSTOMER_ID's (like CUSTOMER_ID_INT and CUSTOMER_ID_EXT). These 2 will be internal and external Cust ID's. Use Java logic to show one of them.

The weird sliding navigation is Apples pride and joy!
That TOC allows you to slide between chapters, sections and pages.
iBooks Authjor was designed to do what it does and what Apple wanted it to do.
Some things can be changed during the books production, but the " weird navigation" is not something you can change to do what you want.
iBooks Author is does not produce ePubs.. at least not as "ePub" is known from Pages, inDesign etc,.
If you want what is available in ePubs.. then iBooks Author is not the application to produce it.
You could drag a section page above chapter on and create an index type page using book marks for links - but whats the point?
People using iPads and familiar with iBooksAuthors special way of book presentation.. are quite happy its so easy to use.

Opening Another Flash File during Run Time

I know, this is too easy. How do I open a Flash.exe file
during run time? I know the code below is wrong but some insert the
correction?
open_btn.onRelease = function () {
play("C:\Documents and Settings\GameOfficeFlow.exe");}
Forever in your debt,
Mike

play() is a timeline command.
I don't think you can have Flash load/play an exe file, but
wait awhile and see if someone else knows better on that one. You
can have it load/play an swf version of a Flash file though.

Reading from a file. How to ask the user for file name at run time????

I have the code to read from a file but my problem is how to prompt the user for the file name at run time.
import java.io.File;
import java.io.FileNotFoundException;
import java.util.InputMismatchException;
import java.util.Scanner;
public class FileRead {
    public static void main(String args[]) {
        Scanner scan = null;
        File file = new File("Results.txt");
        String number;
        try {
            scan = new Scanner(file);
            while (scan.hasNext()){
            number = scan.next();
            System.out.println(number);}

}Any hints would be greatly appreciated. Thank you in advance

I have read through some of the tutorials that you have directed me too and they are very useful, thank you. however there are still a few things that i am not clear about. I am using net beans 5.0 I have placed a text file named Results.txt into the project at the root so the program can view it.
When I use the code that you provided me with, does it matter where the file is, or will it look through everywhere on the hard drive to find a match?
This code compiles but at run time it comes up with this error
run-single:
java.lang.NoClassDefFoundError: NamedFile
Exception in thread "main"
Java Result: 1

import java.util.Scanner;

public static void main (String[] args) throws IOException
    int num, square;
    // this Scanner is used to read what the user enters
    Scanner user = new Scanner( System.in );
    String fileName;
    System.out.print("File Name: ");
    fileName = user.nextLine().trim();
    File file = new File( fileName );     // create a File object
    // this Scanner is used to read from the file
    Scanner scan = new Scanner( file );
    while( scan.hasNextInt() )   // is there more data to process?
      num = scan.nextInt();
      square = num * num ;
      System.out.println("The square of " + num + " is " + square);
}his is the code that i used. It is the same as the code you posted for me (on chapter 23 I/O using Scanner and PrintStream) Sorry im just really stuck on this!!
