Passing values to different classes.

Class A (main panel) calls Class B (calendar panel) and Class C (textbox and buttons panel). When the users changes dates on the calendar class B, class C needs to be notified of the new values.
I have two constructors in class C...an empty parameter constructor that is used when the main panel(A) calls it, and a constructor that accepts an Object as a parameter (which is the list of dates selected on the calendar), used when class B calls it.
My problem is that when the values are changed on the calendar, class C is not holding on to the list of dates. In my constructor, I am enumerating through the list...so I know the values are being passed, but when I try to use the list later on in the code (when a button is clicked) the list is empty.
Does anyone have any suggestions on how to resolve this problem?
Thanks!!!!

you can do something like that:
public someClass {
someOtherClass obj;
public someclass (someOtherClass object) {
this.obj = object;
public void someMethod () {
if (condition) { obj.someOtherMethod(); }
public someOtherClass {
//constructor here
public void someOtherMethod () { //do Stuff }
like this you could pass values between your classes A, B and C

Pass values between different frames

Dear Friends from Adobe.
I need a lot of help from you.
I have a project with Flash Action Script 2.0 and would like
to know if you have to pass values between different frames.
Example:
Passing a value of a inputbox the frame 1 for a inputbox in
frame 2.
OBS: If possible could pass the solution through e-mail?
Now, very grateful.
Diogo Areas.

Using AS2 you can either name the input textfield instance on
the stage or, you can name the variable property of the input
textfield. You can name either of these from the Property Inspector
window. Once named, you can then have access to the value of the
text that is entered. It will be either instanceName.text or
variableName.
The scope of either of these values lasts only as long as the
textfield instance exists. So, if the first textfield is in frame
7, for instance, and is only in frame 7, and you want to use the
value in another frame, say frame 20, then you'll have to store the
value outside of the textfield for later use. You can do this by
creating a variable in the first frame of the movie, and then
placing the text from the textfield in frame 7 into that variable.
Then at frame 20, you can retreive that value and use it in the
textfield in frame 20.
Alternately, you can continue the instance of the textfield
in frame 7 out through frame 20. The content will continue to be
available. You can add keyframes to the layer that the textfield is
in at frame 7, and move the object off the visible area of the
stage, so that it won't be seen, if you like.

Passing values to different thread

how to pass value to diffent threads?
this code dosen't work. the only path that was processed is the "sDirList[1]="//10.81.86.55/ANC_DATA$/";"
public static void main(String[] args){
        sDirList[0]="//10.81.86.55/LOG_FIT$/";
        sDirList[1]="//10.81.86.55/ANC_DATA$/";
         setIndex(0);
         (new Thread(new ListFile())).start();
         setIndex(1);
         (new Thread(new ListFile())).start();
class ListFile() extends thread{
private int ndx=0;
public setIndex(int i){
ndx=1
//open path with the current index
}

If you two threads are sharing variables, then they must be declared as 'volatile'. If you use volatile, then the variables will be stored in main memory, rather in thread specific memory. That means adding volatile keyword should solve the issue.

Navigate from report to dashboard and pass values between different column

Hello
I have a question about navigating from 1 report to a dashboard page while passing the value from column 1 to column 2 in the second report...
In OBIEE 11G, I create action link on report 1, column 1 and this action link is navigate to BI Content and the destination is a dashboard page, which has column 2 used as dashboard prompt and there are 3 reports all use column 2 to filter. Now the column 2 in the dashboard page is an alias of column 1 from report 1, from user's point of view they are the same, but from OBIEE point of view they are different.
My action link is able to navigate to dashboard, however, the value in column 1 which I clicked to execute the navigation, does not get passed to column 2 as the dashboard prompt doesn't get this value upon navigation..
Since I can't put column 1 in dashboard 2 nor can I put column 2 in report 1. Because our data model is done in the way that if I use column 1 or column 2 in both places, it will be circular joins...
Is there a way around this issue?
Let me know if I need to provide more clarification
Thanks

Sid
Here is the thing..
Let's say we have Dimension 1, dimension 2 and fact 1 and fact 2
In one report, you need to show Dimension 2 and fact 1 so Dimension 2 joins to fact 1.
In some other cases, you need to shown dimension 1 and fact 2 stuffs, but dimension 1 can't get to fact 2 without going through dimension 2. So Dim 1 --> Dim 2 --> Fact 2
Then in some other cases, you need to show Dim 1 and Fact 1 reports..
In means, your model will look at:
Dim1 --> DIm2 and Dim 1 --> Fact 1 and Dim 2 --> Fact 1.. This is just a simpler version of a much more complex model that I am dealing with now..
So in this case, you can't just use Dim 1 attributes across the board. For some dashboards, you will have to create alias of Dim 1, call it A1_Dim1, un-join Dim1 with Dim 2 or to fact 1 to avoid circular joins... Then in different reports, you either use columns from Dim 1 or A1_Dim1..
Now Dim1 and A1_DIM1 are really the same thing, but they are not according to OBIEE...
So my problem is, in report 1 where Dim1 is used, it can't past values to Dashboard 2 where A1_DIM1 is used as dashboard prompt..
I want to know if there is a way around this issue
Hope this makes more sense now
Thanks

Handling a value between different classes

Hi there!
Can anyone tell me how to handle this problem?
A value is received at a certain event, that value then needs to be stored somewhere so that two other Classes can access it and then use it.
I hope someone can point me in the right direction.. Some outline code would help if possible?
Thanks :)

okie dokie:
Comms Class handles received Packet events, if it receives a certain packet with a JID (Jabber Identifier) it then needs to store that somewhere else.
//Some outline code
class Comms {
public receivedPacket( PacketEvent pe ) {
JID getJID = pe.packetEvent;
}ChatWindow handles simple chat to the sender of the JID so it needs to get that received JID somehow
//Some guideline code
class ChatWindow {
sendPacket.add( JID );
}EditorChat handles simple shared editing so it too needs that JID to send a packet using that JID
//Some guideline code
class EditorChat {
sendPacket.add( JID );
}My idea for doing this JID handling is completely shot now, but everything else works (thankfully)!
Is that any good? I want to understand how a receivedPacket that contains a JID (which I've already been able to extract can then be stored somewhere else so the two classes (ChatWindow and EditorChat) can use it..?
thanks :)

Passing values between action classes.

there are 2 jsps. main.jsp and detail.jsp In Main. jsp i only enter project description and submit to database and map the struts to call the detail .jsp which has to pick the project id(which is sequence generator) and display its description so I can add the other details of project.
Now the problem is as I submit the aciton the request goes out of scope and I am unable to get the project Id so I can't find the project desc to display in my details page.
i tried populating the form before I leave the save action which is called in first jsp. But I am still not able to get the value of project id. Below is my code
ProjectDetailForm form = (ProjectDetailForm) aform;
......save action is done...
form.setProjectId(projectNumber);
to make it clear project number is the number i wast assing to projectid and its sequence generator in datamap.
In display action where I want value so i can dispaly the project desc in Detail.jsp
ProjectDetailForm form= (ProjectDetailForm) aForm;
int projectNumber=form.getProjectId();
Please anybody let me where I am going wrong. Its kind of urgent.
Regards,
Infyniti.
One wya is querystring, which not preferred in our proj. Is there any susbstitution for querystring in struts.
Its kin of urgent.

I'm not entirely certain what you are doing, but heres a best guess:
If I understand you correctly you want to chain two actions
1 - save action - saves new record, and generates new unique id
2 - display action - displays the new record.
Seeing as you say "the request goes out of scope", I presume that means that your actionForward to go from the save action to the display action is a redirect?
Pro: a refresh won't save a duplicate new record
Con: you lose all request attributes/parameters.
So one request saves the record, and the redirect causes a new request to display the record. But you need to retain the record id between the two requests.
Setting it on the ActionForm should work providing:
- the same ProjectDetailForm used in both the "save" action and the "display" action?
- the form have a scope of "session"
- you don't have a "reset" method that would clear the value between calls
Are you able to post the struts-config for these two actions?
Given the constraints, the only other alternative I can think of is to put the id in a session attribute.
As an alternative, you could make it so that the save action forwards to display without a redirect, but that opens you up to a "refresh" saving a new record again. You could combat that by using struts synchronizer tokens. http://www.javaworld.com/javaworld/javatips/jw-javatip136.html
Hope this helps,

Pass value to a field dynamically..

Hi Experts,
Can any one solve this issue?.
I want to pass value to different fields dynamically..
Egu2026
I have work are having fields
lwa_table-var1,
lwa_table-var2,
lwa_table-var3,
lwa_table-var4,
u2026.. up to lwa_table-var100.
My logic is I have to pass l_tot value .. based on the last letter like below.
if l_tot value is 1 we have pass to lwa_table-var1
if l_tot value is 2 we have pass to lwa_table-var2
if l_tot value is 3 we have pass to lwa_table-var3
if l_tot value is 100 we have pass to lwa_table-var100.

Hi Friend,
U can do Following.....
data: text(12) type c.
data : num type n.
data: int type i.
data: begin of wa_test,
 var1,
 var2,
 var3,
 var4,
 end of wa_test.
FIELD-SYMBOLS <fs_wa> TYPE ANY.
do 4 times.
int = int + 1.
num = int.
CONCATENATE 'wa_test-' 'var' num into text.
ASSIGN (text) to <fs_wa>.
<fs_wa> = num.
UNASSIGN <fs_wa>.
enddo.
write : wa_test-var1 , wa_test-var2 , wa_test-var3 ,wa_test-var4 .
ouput will be : 1 2 3 4.
Lets take Your Scenario----
>>>>>>>>>>>>>>>>>
Data: begin of lwa_table,
Var1,
Var2,
Var3,
u2026..
u2026u2026
Var100,
End of lwa_table.
Data: l_tot type i.
u2022 For example l_tot = 36.
u2022 Then u want to pass the same to lwa_table36.
For this do followingu2026..
Now Define-->>>
data: text(13) type c.
data : num type n.
FIELD-SYMBOLS <fs_wa> TYPE ANY.
*Now till now we done all the data definitions now u have to do following to pass it dynamically,
l_tot = 36.
Num = l_tot.
CONCATENATE lwa_table-' 'var' num into text.
ASSIGN (text) to <fs_wa>.
<fs_wa> = num.
UNASSIGN <fs_wa>.
Write : lwa_table-var36.
Output will be 36.
Hope this resolves ur issue,

Help passing values to graphics

I am able to create some graphics in a stand-alone app, but I am having some difficulty passing values from one class to a sub class of JPanel.

Any thoughts on how to pass the values?Again, I can't read your code, and I doubt anyone else can. I can only give you the generic recommendation that if the data doesn't change you have setters in the class that needs to receive the data and getters in the class that's producing the data. If the data does change dynamically, then you'll probably want to use the Observable design pattern or something similar, something easy to do in Swing.

How to access form objects from different class?

Hello, I am new to java and i started with netbeans 6 beta,
when i create java form application from template i get 2 classes one ends with APP and one with VIEW,
i put for example jTextField1 with the form designer to the form and i can manipulate it's contents easily from within it's class (let's say it is MyAppView).
Question>
How can i access jTextField1 value from different class that i created in the same project?
please help. and sorry for such newbie question.
Thanks Mike

hmm now it says
non static variable jTree1 can not be referenced from static context
My code in ClasWithFormObjects is
public static void setTreeModel (DefaultMutableTreeNode treemodel){
jTree1.setModel(new DefaultTreeModel(treemodel));
and in Class2 it is
ClasWithFormObjects.setTreeModel(model);

Passing values from method array to class array

HELP!! Plz excuse any ignorance. Am a noob and have created an array within my class. I then try to alter those array values from inside one of the classes methods. When I try to access the new values from the class array, they don't exist. I think it's a duration/scope issue and am struggling to get around it. This is the only way I can implement the task required and would appreciate any advice you can thorw. cheers in advance.. =~D

I suspect that you're altering an array passed as a parameter, rather than array that's a field of the instance, but as you didn't post any of your code, that can only be a guess.

Passing array values to methods & Classes

Hi,
I have written the following two classes, I want to pass the value from one class - insersortest to the other class what kind of return statement do I do ? I am not sure what does this Comparable object do in this program ? I am trying the program (algorithm specfieid) from one of the Data Structure book.
import java.io.*;
import java.lang.*;
public class Insersortest
public static void main(String args[]) throws IOException
Insersort ghl = new Insersort();
Comparable a[] = {1, 3, 5, 9, 1};
System.out.println("Detecting duplicates"+ ghl.insertA(a));
-=-=-=-
class Insersort
public static int insertA( Comparable [ ] a )
for( int p = 1; p < a.length; p++ )
Comparable tmp = a[ p ];
int j = p;
for( ; j > 0 && tmp.compareTo( a[ j - 1 ] ) < 0; j-- )
a[ j ] = a[ j - 1 ];
a[ j ] = tmp;
Could somebody provide their view please.
PK

You return arrays just like any object:
public Object[] getArray()Comparable is an interface. Any object that implements Comparable (and can therefore be stored in a Comparable's reference) is guarenteed to have a compareTo method.
Does that help?

Pass a value to a class that extends AbstractTableModel

Hi
I have a problem with a table model that I cannot find a way of overcoming.
I have created a class called MyTableModel that extends AbstractTableModel.
MyTableModel creates and uses another class that I have defined in order to retrieve records from a database, MyTableModel fills the table with these records.
However, I wish to alter my class in order to provide an int parameter that will act as a �where� value in the classes sql query.
The problem is this, I cannot work out how to pass a value into MyTableModel. I have tried creating a simple constructor in order to pass the value but it doesn�t work.
My code is shown below:
import BusinessObjects.JobItemClass;
import DBCommunication.*;
import java.util.ArrayList;
import javax.swing.table.AbstractTableModel;
public class MyJobItemTableModel extends AbstractTableModel
public MyJobItemTableModel(int j)
 jobNo = j;
int jobNo;
JobAllItems jobItems = new JobAllItems(jobNo);
ArrayList items = jobItems.getItems();
String columnName[] = { "Item Number", "Item Description", "Cost per item", "Quantity" };
int c = items.size();
Class columnType[] = { Integer.class, String.class, Double.class, Integer.class };
Object table[][] = new Object[c][4];
public void fillTable()
 if(c > 0)
 for (int i = 0; i < c; i = i + 1)
 this.setValueAt(((JobItemClass) items.get(i)).getItemNumber(), i, 0);
 this.setValueAt(((JobItemClass) items.get(i)).getDescription(), i, 1);
 this.setValueAt(((JobItemClass) items.get(i)).getCostPerItem(), i, 2);
 this.setValueAt(((JobItemClass) items.get(i)).getQuantity(), i, 3);
public void setJobNo(int s)
 jobNo = s;
public int getColumnCount()
 if(c > 0)
 return table[0].length;
 else
 return 0;
public int getRowCount()
 return table.length;
public Object getValueAt(int r, int c)
 return table[r][c];
public String getColumnName(int column)
 return columnName[column];
public Class getColumnClass(int c)
 return columnType[c];
public boolean isCellEditable(int r, int c)
 return false;
public void setValueAt(Object aValue, int r, int c)
 table[r][c] = aValue;
}Any advice will be appreciated.
Many Thanks
GB

your JobAllItems is created before constructor code is run (since it is initialized in class member declaration)
use something like
public MyJobItemTableModel(int j)
 jobNo = j;
 items = (new JobAllItems(jobNo)).getItems();
 c = items.size();
 table = new Object[c][4];
int jobNo;
ArrayList items;
String columnName[] = { "Item Number", "Item Description", "Cost per item", "Quantity" };
int c;
Class columnType[] = { Integer.class, String.class, Double.class, Integer.class };
Object table[][] ;instead of
public MyJobItemTableModel(int j)
 jobNo = j;
int jobNo;
JobAllItems jobItems = new JobAllItems(jobNo);
ArrayList items = jobItems.getItems();
String columnName[] = { "Item Number", "Item Description", "Cost per item", "Quantity" };
int c = items.size();
Class columnType[] = { Integer.class, String.class, Double.class, Integer.class };
Object table[][] = new Object[c][4];

Pass values between panels in different UI files

Hi All,
Is there a way to pass values between panels belonging to User Interface files ? Or is it easier to have one .uir and different .c and .h files ?
Thanks,
Kanu

I should say that it's not possible for you to trap events from the first popup,and this depends on the basic concept of "popup panel".
When you install a popup panel, all user interaction with existing panels is excluded: all focus it aimed at the popup only, no other user interface event is generated. If you launch another popup from the first one, the second popup prevails over the first one and no event can be generated on the first panel until the second one is closed.
Handling a chain of two popup panels while looping on GetUserEvent can lead to unpredictable situation not so easy to untangle.

Pass values between views of different window

Hello Experts,
I am a newbie in ABAP Webdynpro. I have 2 views in 2 different windows. I want to pass values calculated from one view to the other view. But i cannot connect the views.
If the views were within the same window, I could connect them using inbound and oubound plugs with parameters. However in this case i am unable to establish the navigation link between these 2 views.
Has anyone of you experts come across such kind of requirement? If so, can you please guide how to connect the 2 views?
Thanks and regards,
Nitish.

Everyone,
I was finally able to connect the 2 views by using the component controller.
I created an attribute on the context of the component controller and read/set of the attribute of component controller on the button click event.
To access the attribute of the component controller, please find below a code snippet which was useful to me:
Data declaration for accessing the component controller
DATA:
       lo_component     type REF TO if_wd_component,
       lo_context       type REF TO if_wd_context,
       lo_controller    type REF TO if_wd_controller,
       lo_node          type ref to if_wd_context_node,
       lo_child         type REF TO if_wd_context_node.
DATA lo_el_test_depts TYPE REF TO if_wd_context_element.
get component controller API
lo_component = wd_comp_controller->wd_get_api( ).
lo_controller ?= lo_component.
accessing the context of the component controller
CALL METHOD lo_controller->get_context
   RECEIVING
   context = lo_context.
lo_context is the required context, from here we can manipulate its components
get to the root node in context of component controller
lo_node = lo_context->root_node.
using lo_node i was able to read and write to the attribute i created in component controller.
Thank you all for your help.
