Working with millions of object!

I am needing to be able to process around 2,000,000 objects. Each object is a point on a map.
It seems that java is not able to handle this many object in memory. I presume I therefore need to somehow create these objects and store/reference them on some sort of stored media(e.g. hard disk).
Am I on the right track?
Has anybody had to handle such large volumes of unique objects before?
John

And some of us don't have all day to tell you what all
the millions of acronyms stand for.
Instead of getting all sarcastic and offended, maybe
you should take my advice and STFW before taking up
both your time and ours with a question that can be
easily answered by a search engine. Using the STFW
method, I found that it took me exactly 16 seconds to
open a browser, go to Yahoo, do a search on "STFW",
and click on the link that gave the definition. Do you
think you could get a response to your question on the
forum in 16 seconds? STFW and RTFM are commonly used
acronyms for a reason... they work.Listen, I'm not even the person who asked the original question so don't blame me for not looking on the internet. I did search the web to find out what your remark meant before you even replied, thanks for enlightening me.

Additional plug ins not displaying when working with ERBI Business Objects.

when working with ERBI Business Objects I am attempting to edit a report which requires Java. When I click on edit I get a bar at the top of the screen that say "Additional plugins are required to display all the media on this page". I click install missing plugins and receive a page that says no suitable plugins were found. I click finish and thus it still won't allow me to edit a report.
Please help

Please go to Java's website in this case to download Java.

Working with Portal Display Objects Slowsdown Portal

Hi,
I am working with Portal Display Objects. I have to create a theme from an existing standard template.
But as soon as I start working with Theme Editor,
the Portal slows down and almost stops responding after
some time. I had to restart the J2EE services every time
I used theme editor. Did anyone encountered this problem and got around with it ?

Working with a smart object

I just watched a tutorial for the new blurs in Photoshop CS6. They instructed to convert the pic to a smart object. But when I did that the iris, field and tilt shift blurs were not being allowed to be applied. Any suggestions as I am not that familiar with working with smart objects

The feature you want isn't in 13.0.1. You need Creative Cloud Photoshop 13.1.2 for Blur Gallery as Smart Filter attached to Smart Object.

If you have Windows then you need Windows 7 or 8 for Ps 13.1.2. What is your OS?

How to work with the same Object in different computers?

I'm working with Players, and I have to pass them to the server from the client..how can I meke that?
Thanks

Just to clarify, the OP is talking about "javax.media.Player".
(He previously discussed the question on a different forum).

Working with many overlying objects

When trying to select a particular object that is partly under other objects, you can run into a problem. The solution has been stated before - drag from the margin.
The problem with dragging from the margin is that it often leads to selecting partly overlaying or partly underlying objects. If there are a number of these same proximity objects, it becomes all the worse. You have to deal with Shift click to try and deselect these other items in the same proximity. This can be finicky at times.
A partial solution would be that Apple incorporate a single key shortcut that forces the arrowhead cursor to show itself. And of course, when holding this key down, the arrowhead selection cursor should be fully functional. It also should be made to work in conjunction with the Shift key for selecting multiple objects, when desired.
A better and more advanced solution would be to borrow from the CAD world for one. A great solution would be to have an OBJECTS PALETTE. This would solve this close proximity and selection issue.
You should be able to name objects (or parts of the layout), select objects, make them selectable or not, lock them, hide objects -- all from within this one palette. Evertime you create a new object or part of the layout, another default name would appear in this palette - e.g. 'object 13'. The name could then be modified, and the above conditions for each object, such as 'lock' could be selected or not from within this palette. This is done well in a program named form•Z. You can check the program out at form•Z.com.
Mac OS X (10.4.4)

One thing to realize is that you do not need to drag from the outside to the center of the object. I am able to select the object I want by dragging from the outside to a corner of the object...and no other objects are selected.
I too, would love a shortcut key to select objects. I hope this eventually makes it into the features. Till then I will use the drag option, something I probably never would have figured out without the help of people on this forum.

How to get custom graphics to work with the animator object

I Have a costom graphic that I wish to have change color depending the position of a Pot, and have tried using the animator object. However the animator object fails to change color when the pot is moved, when i replace the costom graphic with a standard one (a pipe) the color changes perfectly. The costom graphic is in wmf format so it should work. what am i doing wrong or is this just not possible?

Hello,
That's a little odd. Did you trying playing with the Gray Proximity settings? If it's not too difficult maybe you can create various colored versions of your graphic and use the Multistate object instead.
Is it possible to post the picture here so we can try?

Best way to work with multiple Flash objects?

I am making an application that is going to need to use several custom MovieClip-based classes from Flash. I'm not sure if I'm using the terminology right. What I have is a Flash file with movie clips, each clip has a class with properties and methods. Many of the methods control what happens in the clip.
For example, if there was a clip "Person" with walking and sitting animation, there are methods "sit" and "walk" which would play the appropriate parts. I need to add dynamically several "Person" clip/objects to the Flex app, and command them to walk or sit when needed.
What's the best workflow for this? How do I save the clips? Or is is best just to do the whole thing in Flash?

Have you looked into using the Flex Component Kit for Flash?

Details from ST22----
An exception occurred which is explained in detail below.
The exception, which is assigned to class 'CX_WDR_ADAPTER_EXCEPTION', was not
caught and
therefore caused a runtime error.
The reason for the exception is:
Adapterfehler im INPUT_FIELD "INPUT_FIELD01" des Views
"Z_BP_GENERAL.VIEW_VAL": Context-Bindung des Properties VALUE kann nicht
aufgelöst werden: Node VIEW_VAL.1.POP_IN does not contain any elements
The occurrence of the exception is closely related to the occurrence of
a previous exception "CX_WD_CONTEXT", which was raised in the program
"CL_WDR_CONTEXT_NODE===========CP",
specifically in line 9 of the (include) program
"CL_WDR_CONTEXT_NODE===========CM00R".
The cause of the exception was:
Node VIEW_VAL.1.POP_IN does not contain any elements

hi,
Use this code in OnAction of LinktoAction UI element.
This code will give you index of the row from which Link to Action is Triggered.
<cn_popin> is my node binded to Table.
data: lr_element type ref to if_wd_context_element.
DATA ls_cn_popin TYPE wd_this->element_cn_popin.
lr_element = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
get all declared attributes
lr_element->get_static_attributes(
IMPORTING
static_attributes = ls_cn_popin ).
data lv type I.
lv = lr_element->GET_INDEX( ).
Finally you have the index in varialbe lv.

Working with ActionScript ByteArray objects

This question was posted in response to the following article: http://help.adobe.com/en_US/air/extensions/WS460ee381960520ad-866f9c112aa6e1ad46-7ff5.html

What happens if the length of the ByteArray changes? Is it possible to allocate a new portion of memory and return that? In such case, which side would be responsible for deallocating it?

XPath query works with CLOB but not with object relational

hi all
i have the following queries,the XQuery work with all, but XPath queries work with XMLType CLOB and Binary XML, but they do not work with XMLType as Object relational,
select extract (object_value,'movies/directorfilms/films/film [studios/studio = "Gaumont"]')
from xorm;
select extract (object_value,'movies/directorfilms[director/dirname = "L.Cohen"]/films/film[position()=2]/t')
from xorm;
they shows this message

Hi Marco
fisrt here is my RO

xmltype store as object relational
XMLSCHEMA "http://......../ORMovies.xsd"
ELEMENT "movies";
INSERT INTO XORM

here the XQuery format that work fine with the OR
A/D
select XMLQuery ('for $a in movies/directorfilms/films/film
          where $a/studios/studio = "Gaumont"
          return $a'
     passing object_value

child element query

          return $b/t'
     passing object_value
     returning CONTENT)"TitleX"

here is the XPath format which doesn't work
select extract (object_value,'movies/directorfilms/films/film [studios/studio = "Gaumont"]')
from xorm;
select extract (object_value,'movies/directorfilms[director/dirname = "Feyder"]/films/film[position()=2]/t')

by the way all queries work fine with the CLOB or Binary XML
many thanx Marco

Working with collections

I am having an issue with working with lists of objects and would greatly appreciate some help on this. would like to cast indirectlist to arraylist.
I have a collection of data declared as below.
private Collection<PersistableTableData> tableData = (Collection<PersistableTableData>) new ArrayList();
then I try to access the data like below.
ArrayList<PersistableTableData> td = (ArrayList<PersistableTableData>) tableData;
but I get an error...
java.lang.ClassCastException: oracle.toplink.essentials.indirection.IndirectList cannot be cast to java.util.ArrayList
The question is am I doing something stupid here? I know I can create an arraylist like..
ArrayList<PersistableTableData> td = new ArrayList<PersistableTableData>(getTableData());
but it seems like that is allot of overhead when the list was created as an arraylist to begin with.
Is there a better way todo this?
Thanks in advance

What is the reason for trying to get the collection values outside of the session? Maybe
there is no need for that. If you want to query the table, you need to grant access to that
table to your workspace user and I wouldn't recommend that practice. Also, since your
application has many sessions, the data you get will be multiplicated by that factor.

BC4J: problems creating view object with multiple entity objects

Hi,
I working with a view object which contains two entity objects with parent-child relationship like this:
ViewObject - ParentEntityObject - PId
PAttribute
CId (FK)
(- ParentChildAssociation)
- ChildEntityObject - CId
- CAttribute
The 'Read Only' and 'References' options are checked for the association in the view object.
I'm creating a new row using this view object. The parent object should be created new and the child object already exists in the database, so I'm setting only the attributes of the parent object (including foreign key).
After creating the row I display it in a jbo:DataTable and only those attributes coming from the parent object are displayed. The attributes of the child object are not set. After a commit all attributes appear.
The problem is, that I want to display the new row with all attributes to the users BEFORE they commit.
I tried to set the child attributes, but they are read only by definition and even when I unchecked the 'Read Only' option and set the attributes to 'Always Updateable' in the view object it is giving me
JBO-27008: Attribute set for CAttribute in view object ViewObject failed.
Is there a way to make all attributes of the child object visible in the view object without committing changes?
(JDev 9.0.2.822)
Any help would be appreciated.
Regards,
Christian

Once again the structure, sorry.
ViewObject
|-ParentEntityObject
..|-PId
..|-PAttribute
..|-CId (FK)
|-ParentChildAssociation
|-ChildEntityObject
..|-CId
..|-CAttribute
Christian
