Need help on -- Size of object
how do i get the size of the object ?
Thanks in Advance
You can't. What makes you think you need this, because in Java we don't need to worry about this. You do not explicitly allocate or free memory, so the size of an object is not needed. Some people will tell you to serialize an object to a byte array and that the size of the array is the size of the object, but they're completely wrong. The size of an object is, roughly, the size of every primitive field it has, plus the size of a reference to an object multiplied by the number of reference fields, plus a small overhead for simply existing itself. But as I said, you don't need to worry about it

Urgent. Need help in the Calendar Object.
Hello developers, best regards!
Well my problem is that i'm facing a fact that i need a calendar object just like that one when u click the time down there in the taskbar, i need to embedd it in my java windows application.
To be more clear, if u're familiar with the Visual Basic.NET environment, just the kind of calendars that i need is found there, in which it displays a small box which i can select the months, and accordingly i can select the specific date i need.
Please i need your help so much.

Need help changing size and aspect ratio for 500+ images
Thank you for reading this! I have about 500 images of people in different poses. They're all extracted on a transparency as PNGs. They vary in aspect ratio, dimensions and position of the person within the frame - for some the feet are very close to the bottom of the frame and for some, they're higher up. I need to equalize all 3 of these qualities, so that if superimposed, they look like a video unfolding with the same zoom. My ideal size would be 800x800 at 300ppi.
Is there a way to batch even a part of the process and keep the png format? I had the images in PSD initially but they were too massive so creating catalogs with them was prohibitive.
If not possible to do a batch, what would be the best (easiest) and fastest way to do it? I'm thinking that maybe creating some template where an oval shape the size of the head can help create consistency of the size of the person and a line that helps set up the distance from the bottom?
I so appreciate any help you have to offer. Part of my problem is that I don't know what these processes are called so I don't even know what to search for. If you can even name the actions that I need, it would be of great help. I already paid a designer to do the extraction and they were supposed to do this formatting as well and they didn't so my budget is shot. I'm hoping that if I understand what the steps are, I can do them myself.
Thank you!If you download my crafting actions package you can record an action that uses one of my plug-in scripts to do that process. You could then batch that action and process your 500 png image files.

I'm sure the should work you mane not need the copy paste and it depends on how Photoshop treats the PNG layer the canvas size or just the pixels.

Need help! Simple session object problem.
Help! I've been working on this for 4 days, but I'm sure it's simple if you are experienced. I'm receiving an error when I try to create the session variable (line 29)
I just want to
A) take the record ID's from a string variable on a sort page,
B) create a string session variable which has those ID's
C) and then pass it to the cart page, where the ID's will be used to display multiple records.
1) (From the sort page), using an ADD TO CART BUTTON, Pass the record ID's in the String chkValues[] to a session variable.
2)Figure out how to be able to access that session variable from the cart page: (The issue is that the form on the sort page already uses a GET method to perform the sort.)

%>Thanks so much for your informative response!
I would value your advice and direction to correct the structure of the code, but I am a very methodical person and first must complete the prototype in JSP before I go on to the next step of applying the MVC structure to correct the inefficiencies. (Also, it will be invaluable to the learning process be able to compare the two.) Just as in learning Math, you must learn the long way of problem solving before you apply the sophisticated, less error prone, and more structured approach.
I have a sort that works pefectly, and displays only the records that have "checks" in the checkboxes. By unchecking the checkbox for individual records, (and then pressing the Sort/Select button), the sort is re-run using only the ID's of records that have been "checked."
When ADD TO CART is pressed, I want to pass the ID's from the displayed records to a persistent session variable. And then when "DISPLAY CART" is pressed, I want to view a sort page EXACTLY like the original sort page, except the variable holding the diplayed records IS the persistent session variable. I'm not sure how to add only unique ID's to the session variable?
I'd appreciate any assistance to complete this step, so I can go on and develop the MVC structure.
Thank you again.

Need help with OCI8::Cursor object
I'm using ActiveRecord::Base.connection.execute to run a SQL statement against an Oracle schema that is "external" to my Rails database.
I'm building the connection on the fly using connection parameters stored in my Rails database (MySQL).
So far so good...I can create the connection and run the query...I'm getting back an OCI8::Cursor object and that's where I'm stuck.
I need to display the results of the query in a Rails view.

My problem is that I simply don't have a firm enough grasp on the basics of Ruby to dissect this thing and get at it's innards.
If someone could drop me a code snippet that shows how to reference the contents of this in my erb file I think I'll be off to the races.If you want low level access to Oracle database then you can use ruby-oci8 API directly without using ActiveRecord.
You can read about ruby-oci8 API at http://ruby-oci8.rubyforge.org/en/api.html
But if you want to use ActiveRecord then install and use oracle_enhanced adapter, see http://wiki.github.com/rsim/oracle-enhanced
If you have any questions about oracle_enhanced adapter then probably it is better to ask them in http://groups.google.com/group/oracle-enhanced discussion group.
It is not recommended approach to establish ActiveRecord connection and then use low level ruby-oci8 API.
And if you have some problem then please describe exactly what you are doing and what you would like to achive and then also what error do you get. -
Hello everyone. I have a quick question. When my program opens I have the window open to the max by getting the screen size dimension. I also have a text area in the frame that I would like do to the same. Any ideas? I have tried setRow, setCol but the problem is these will vary across computers. I tried textArea.setSize(dimension of screen) but this only accounts for the cols, not rows so it sizes the cols to the max but not the rows.
Gotcha, ok I must be doing something wrong somewhere. Thanks for helping me out, I will post my code. Also, looking back at my code I was not using border layout so this may have been the problem. Can you take a peak though? It may be something else. I would basically like the text area to resize when the window does but always fill up all the space under the menu. If I can get this working I'm almost done since all the functionality works. I left out that code though to shorten this up some, I mainly added the code where I create and add the panel to the frame.
This is the driver, basic creation of the frame
import javax.swing.JFrame;
import java.awt.*;
public class Run {
public static void main(String args[]) {
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Notepad n = new Notepad();
n.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
n.setSize(screenSize);
n.setVisible(true);
}Here is the panel where I store the text area
I also use this class to handle operations on the text area such as reading/writing to disk etc. I left out the functionality code to keep it small and to the point.
public class NotepadFile extends JPanel {
private JTextArea mainTextArea;
public NotepadFile( ) {
setLayout(new FlowLayout()); //default
mainTextArea = new JTextArea();
mainTextArea.setLineWrap(true);
add(mainTextArea);
}Finally, here is where I add the panel to the main frame. Again, i'm leaving out the functionality code like event handlers and such.
public class Notepad extends JFrame {
private NotepadFile nFile;
private final int fileMenuIndex = 0,
formatMenuIndex = 1,
helpMenuIndex = 2;
public Notepad( ) {
super("Notepad");
JMenuBar mainMenuBar;
JMenu menu[];
nFile = new NotepadFile();
mainMenuBar = new JMenuBar();
setJMenuBar(mainMenuBar);
menu = new JMenu[menuNames.length];
for(int i=0;i<menuNames.length;i++) {
menu[i] = new JMenu(menuNames); //create a menu
menu[i].setMnemonic(menuMnemonic[i]);
//here is where I created menu items but I cut it out here
//continued..
for(int i=0;i<menuNames.length;i++)
mainMenuBar.add(menu[i]); //add menus to menu bar
add(new JScrollPane(nFile));
//here I also tried add(new JScrollPane(nFile), BorderLayout.CENTER); but it didn't work -
NEED HELP! passing an object array to a method
Hi, i need to make a method called public Server[] getServers() and i need to be able to see if specific server is available for use.
I have this so far:
public abstract class AbstractServer
protected String serverName;
protected String serverLocation;
public AbstractServer(String name,String location)
this.serverName=name;
this.serverLocation=location;
public abstract class Server extends AbstractServer
public Server(String name,String location)
super(name,location);
public class CreateServers
Server server[];
public CreateServers()
public Server create()
for(int i=0; i<10; i++)
server=new Server(" ", " "); //i was going to fill in something here
return server;
OK NOW HERE IS THE PROBLEM
i have another class that is supposed to manage all these servers, and i dont understand how to do the public Server[] getServers(), this is what i have tried so far
public class ServerManager()
public Server[] getServers(Server[] AbstractServer)
Server server=null; //ok im also confused about what to do here
return server;
in the end i need this because i have a thread class that runs the servers that has a call this like:
ServerManager.getServers("serverName", null);
Im just really confused because i need to get a specific server by name but i have to go through AbstractServer class to get it
Any help?ok, right
since i have to call this method in the thread class saying
ServerManger.getServer(AbstractServer[]) //to see if i have all the servers i need to proceed
im confused about how it should be declared in the actual ServerManager
should it be like
public Server[] getServers(AbstractServer[]) ???? and then have it return all the servers it has
thats the part i dont get, because instead of saying ServerManager.getServer(string, string) i want it to go and find out if i have all the servers i need to continue
does that make sense? sort of? -

Need help serialize a collection object
I have a class that's going to manage a list of paths stored as strings as "ArrayList<String> fileList = null;". I can't figure out how to serialize the fileList object. The class that contains the fileList implements Externalizable. here are the read and write functions:
public void readExternal(ObjectInput in) throws IOException
fileList = (ArrayList)in.readObject();
public void writeExternal(ObjectOutput out) throws IOException//, ClassNotFoundException
out.writeObject(fileList);
}I've tried lots of different things and nothing works. Anybody know how to serialize an ArrayList? Is ArrayList the best class for the job?I have a class that's going to manage a list of paths
stored as strings as "ArrayList<String> fileList =

fileList object. You don't have to do anything to serialize ArrayList, it is already Serializable.
The class that contains the fileList
implements Externalizable. here are the read and
write functions:I will assume there is a good reason this class (that contains the fileList) can itself not be Serializable and needs to be Externelizable.

works. Anybody know how to serialize an ArrayList? Is
ArrayList the best class for the job?I tried the same example -- with code to make it compilable and testable -- and it works as expected.
What exactly do you mean when you say "nothing works"? -

Re: need help to create document object
Hi there,
I am new to C3PO stuff and would anyone kindly give me a hand? I am trying
to create a Document object out of the Message object, but it always give
me error:
err.description= object required
err.number=438
err.helpcontext= 1000424
here is the actual code using VB
==========================================
Dim objSelectedMessages As Object
Dim objMessage as Object
Set objSelectedMessages = g_C3POManager.ClientState.SelectedMessages
Set objSelectedMessages = objSelectedMessages.Find("(DOCREFERENCE) AND
(<Document Status, STRING> CONTAINS NOT ""Final"")")
For Each objMessage In objSelectedMessages
DoSomething objMessage.Document
Next
==========================================
Everything works great before we upgrade to GroupWise 7(from ver. 6)...
Thanks for reading this post.
Sincerely,
PhilipThanks Michael and Glade, I really appreciate the input.
I am sorry that I should have include the doSomthing method code, here it
is:
here is the actual code using VB
==========================================
private sub CheckDocFinalStatus()
Dim objSelectedMessages As Object
Dim objMessage as Object
Set objSelectedMessages =
g_C3POManager.ClientState.SelectedMessages Set objSelectedMessages
= objSelectedMessages.Find("(DOCREFERENCE) AND
(<Document Status, STRING> CONTAINS NOT ""Final"")")
For Each objMessage In objSelectedMessages
DoSomething objMessage.Document
Next
end sub
private sub doSomething(byval ADocument as object) <-- error occurs here
If ADocument is nothing then
else
end if
end sub
==========================================
The error occurs as soon as I called doSomething Method, it won't allow me
to create the document object at all. Seems to be missing a reference in
my development environment because when I looked at the vb6 intellisense,
there is no child object for the message.document.
I know this is silly but is message.document object part of the GW Object
API, right? I think I am missing something...
And I will definitely install the GW7 SP1 as soon as possible and keep you
guys update how it goes.
Really appreciated.
Thanks,
Philip

Need help for finding objects impacted by size change for an infoobject
hi all,
need help for finding objects impacted by size change
for xxx infoobject, due to some requirements, the size to be changed from
char(4) to char(10), in the source database tables as well as adjustment
to be done in BI side.
this infoobject xxx is nav attribute of YYY as well as for WWW
infoobjects. and xxx is loaded from infopkg for www infoobject load.
now that i have to prepare an impact analysis doc for BI side.
pls help me with what all could be impacted and what to be done as a
solution to implement the size change.
FYI:
where used list for xxx infoobject - relveals these object types :
infocubes,
infosources,
tranfer rules,
DSO.
attribute of characteristic,
nav attribute,
ref infoobject,
in queries,
in variablesHi Swetha,
You will have to manually make the table adjustments in all the systems using SE14 trans since the changes done using SE14 cannot be collected in any TR.
How to adjust tables :
Enter the table name in SE14. For ex for any Z master data(Say ZABCD), master data table name would be /BIC/PZABCD, text table would be /BIC/TZABCD. Similarly any DSO(say ZXYZ) table name would be /BIC/AZXYZ00 etc.
Just enter the table name in SE14 trans --> Edit --> Select the radio button "Save Data" --> Click on Activate & adjust database table.
NOTE : Be very careful in using SE14 trans since there is possibility that the backend table could be deleted.
How to collect the changes in TR:
You can collect only the changes made to the IO --> When you activate, it will ask you for the TR --> Enter the correct package name & create a new TR. If it doesn't prompt you for TR, just goto Extras --> Write transport request from the IO properties Menu screen. Once these IO changes are moved successfully, then the above proceduce can be followed using SE14 trans.
Hope it helps!

Pavan
