Should I load properties and or preferentces into a hashmap??

Would this make any difference performance wise?
I use properties mostly for localized labels so it shouldn't affect much as they're loaded only once. But my code is checking preferences quite often...
On the oder hand prefferences are writen to storage asynchronously but... is this true for reading? does the jvm maintain some kind of preferences cache or does it access back end for each prefference read?
Thanks in advance,
David

oh, I'm sorry if I didn't express my question correctly, let me try again :-)
I'm using both properties and preferences for two distinc pourposes:
First I use properties for localization. I'm not really bothered for performance in this case as these are read only once at startup anyway. I was jus curious.
Second I use preferences for application configuration data persistance. Say the current db url, or some path... This preferences are to be checked a lot of times during programm execution, hence the question.
If preferencesr were not cached by the system then it would make sense to load them into a hashtable at startup and use this instead. If they were in fact cached by the system then I would preffer to stick with the convenience of having the jvm storing them automatically at shutdown time.
Third: there are probably many performance problems in your code,This I'm sure but I've to try caching any problem I can see :-)
Fourth: Property objects are loaded once and then cached.Ok, this part is now clear thaks to your reply and the one from sabre which, of course, I thank a lot.
Regards,
David

Tough without the Tiger Disk problems, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
(SPACE between fsck AND -fy important)
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: 
The volume (name_of_volume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: ***** FILE SYSTEM WAS MODIFIED *****   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

Then Safe Boot, (holding Shift key down at bootup), & use Disk Utility from there to Repair Permissions, reboot once more.

TS1702 When I tried to update existing Pages app it did not complete loading update and has 'locked' into loading mode. I do not want to trash the existing Pages because it contains documents I need. Any advice?

My problem is that when attempting to load updateed Pages the app has frozen in 'loading' mode and will not complete the loading. It is now unusable and does not respond to turning off the iPad and restarting. The Pages icon is in 'shadow' and will not respond . Cannot get the red minus symbol. Can get X symbol but do not want to trash it because it contains many documents I do not want to lose. Suggestions welcome!

Try a Reset [Hold the Home and Sleep/Wake buttons down together for 10 seconds or so (until the Apple logo appears) and then release. The screen will go blank and then power ON again in the normal way.] It is app and data safe!

Load, Resize and Position SWF into a blank MC

heeelp!!
I've honestly tried to look everywhere and have no clue how to do this. PLus i've tried for hours and still have no success!
As the post thread title states, I have a swf file and i want to import anothe swf file into a blank movie clip. Any ideas how? Can it be % wise? And can the image's width be set to say 100 and the height be automatic?
Also, what about the x and y positioning?
also, I do not need or want a progress bar....
I would really be greatful if anyone can lend me a hand.

Hope you include file path as an argument inside URLRequest constructor.
Ex:
loader.load( new URLRequest("bla.swf") );
That may be the reason you are getting an erroe.
Just throwing a stone in dark......

My White Macbook is stuck at the loading screen, and disk utility, safe mode doesn't work either. What should I do?

I went on vacation a few days ago and in El Salvador, they have this mobile broadband sticks. Well, I was using one until it gave me a network error. After that, it shut down my computer entirely. The first time it happened, I didn't think much of it. I took the battery out and put it back in for it could work. It happened another two times, and after the third time, my MacBook stays stuck at the loading screen, and it will take 5-10 minutes on that screen, before it shuts down, or it wouldn't turn on at all. I've tried booting into safe mode, but it appears to not boot into it. I've tried resetting the Pram, and using disk utility, but that still won't work. I don't know what else to do to make it boot into OS X Lion.
I'm an AP student, and the majority of my work is in that computer, and it is very important! What can I do? Not only that, but I enter school in a few weeks and I need the AP work by the time I enter.
What can I do? Can someone help?
Thanks

Reinstalling Lion Without the Installer
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

I had the same problem after I gave my old iPad to my parents and tried to install Netflix. This is what you have to do: Open iTunes on your computer, the one you sync your iPad to. Then go to iTunes Store and search for and download Netflix app. After you download it, if your iPad is set to download new purchases it may start downloading on your iPad. If so, tap and hold to delete the app (because it is trying to install the new version on the iPad) Next step, go to the App Store on your iPad and find Netflix and it should say install since you already purchased it on the computer. Tap to install, and it will say the version is not compatible, tap to download a previous version. Click that and it will install the older version! One more thing, if and when you sync to your computer again it will say something like " Unable to install Netflix on your iPad" Just click the box to never remind you again, because it's trying to sync the newer Netflix app to your iPad, but it doesn't work so it displays the message. The old app will remain on the ipad. Hope this helps, good luck

Can ResourceBundle load .properties from files and .jar?

Hi Guys,
I'm trying to I18N an application with ResourceBundle.
Suppose my class look like this:
package pack;
import java.util.ResourceBundle;
public class MyClass {
public static void main(String[] args) {
ResourceBundle rb = ResourceBundle.getBundle("Language");
}This would load the localized string from Language.properties
And when I pack the class file and Language.properties into a jar. It works fine
But what I tried to do is to make the ResourceBundle try to load from external file first
before it load from the jar file so that if I have a new language file I can just drop in the
NewLang.properties.
Inside .jar file look like this
/Language.properties
/pack/MyClass.class
/meta-inf/Manifest.mf
I tried look into some forum and they suggest to include Class-Path in Manifest.mf file
to include current path like this
Class-Path: .
But still, it didn't work. If I include .properties in .jar it will not look outside but if I didn't include
any .properties it found a properties file.
How can I achieve this ?

Dave,
I reckon you're on the right track... just have to figure out "what's the path to properties file"... I suspect you've got a context problem... not sure... I'm pretty new at this stuff myself.
So, what's your development environment? O/S, IDE, app/web-server, etc.
Cheers. Keith.

Failed to load class properties and qualifiers for class BDD_UsePackage in task sequence. 0x80041002

Following situation. In SCCM we have one Standalone Primray Site Server and two Site Server. The two site server are also SMS Provider. MDT 2012 was installed on all three Servers and the Config Manager Integration was run. When starting the Console
on any of this server and editing an MDT Task Sequence, it occasionally pops up an error "An error occured when loading the task sequence". TaskSequenceProvider.log File throws a lot of errors:

Tried removing the integration on all SMS Provider Machines and readded them. It does not make a differenence. Does anyone know if MDT supports the use of multiple SMS Providers? When I only use one Provider and deinstall the other two, it works ok.

Why should we load header data first and then we load item level data?

Hi BW guru`s,
I have small confusion about the data loading.
Why should we load header data first and then we load item level data?
Is there any particular reason?
Scenario: 1st I have uploaded 2LIS_11_VAHDR sales document header data from R/3 to BW by using LO-Cockpit extraction. Then I loaded 2LIS_11_VAITM.This is the norma procedure which we use to follow.
I have a question. If I load 2LIS_11_VAITM data 1st from R/3 to BW and then I will load 2LIS_11_VAHDR by using LO-Cockpit extraction. what will happen?
Regards,
Venkat

There is no difference in doing it the other way.
The load sequence will come into play only during activation where if you map the same fields from the two datasources, you might want to have the previous value overwritten by data from the next datasource.
That is when you should care about loading one datasource before the other.
To your question it is not arule that header data should come first.

iPhoto just stopped working. It loads pictures, but then goes into rainbow wheel forever. Then I try to force quit it, and then the whole Mac hangs up (had to power cycle it to get it back). I am using OS 10.5.8, and when I run software update, it assures me I have up to date software. I have not added any photos since the last time I used it, probably less than a month ago. What gives?

Try these in order - from best option on down...
1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library allowing it to overwrite the damaged file.
2. Download <a href="http://www.fatcatsoftware.com/iplm/"><b><u>iPhoto Library Manager</b></u></a> and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
3. If neither of these work then you'll need to create and populate a new library.
To create and populate a new *iPhoto 6* library:
Note this will give you a working library with the same Rolls and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library on your desktop and find the Originals folder. From the Originals folder drag the individual Roll Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.

I am an absolute newcomer to Lightroom. I have downloaded images from camera (OMD EM1) and divided them into folders. Some folders work ok in Develop mode. With other folders I get the words "This file could not be found". What should I do

When I go into Develop mode, some folders can be developed ok , but with images from two other folders I get the message "This file could not be found". What should I do?

may i suggest opening the files in Olymous Viewer 3 and exporting them (you can do some editing there if you wish or not) asTIFF files. After that you can import the new files into LR. LR seems to like tiiff more than .orf files
The advantage to using OV3 is that it seems to do a much better job converting RAW EM1 files. Colors are more accurate ( my red flower pot turned orange when loaded directly into lightroom)
. The tiff files just LOOK better in LR after the conversion . there is a youtube on this subject and when i tried it myself i was impressed

Should I load product info into memory or keep in db?

Hi,
I am going to develop a b2c shopping website with jboss-tomcat bundle. Now I must make a decision on whether I should load product info into memory or just keep it in table. If load into memory, the performance of customer browsing and searching will be good; but I am afraid of the memory capacity and issues like, when I want to update the product price or description, I need to refresh the memory objects. This shop has about 500 products and we will develop this application into Dell server with 1GB memory. Can anyone who has ever developed such e-commerce website give me some suggestions?
Thanks.

I usally use XSLT enabled servlets using Apache Xalan http://xml.apache.org
Its as easy as caching the result of a transformation for a particular URL request in a generic servlet against the string url and putting htem in a HashMap.
Usual architecture is EJN stateless session beans sending xml to a servlet which styles it and caches the result according to configuration.
Work out cache expiry etc later once you get things going.
To answer your question completely, it would be on the servlet side that I would do the caching.
You may be able to do it using servlet chaining or filters, although I have not tried this but have seen some tutorials about this sort of stuff.
The main concept of page caching is storing the whole html page in memory in the servlet (or in a Java class structure contained in the servlet) and whenever a page request matches a cached entry, just send the cached html straight at the browser, instead of expensively creating a new dynamic page.
Consider implementing gzip encoding as well and storing zipped pages in memory, much faster. Avoid implemrnting stuff that a proxy server would give you out of the box.
I usually try to configure what urls are cached and what are not.
If you are using JSP, I am sure someone has implemented caching of jsp content, a preoduct called Tiles perhaps?

However, error 1604 is list and users have reported that error number. If 1604 is the error number the following tell yu wnat to do when you click on that error number:

Loading File name and file contents into two separate tables using Sqlloadr

Hi All,
I have situtation like to load File contents into One table and File name into one table . File comes with .txt extension
Example :
File name : product_09_abc.txt
File contents :
Productcode
ABC
CDE
EFT
Can you please help me out this how can we acheive this using SQLLOADER.

SQL*Loader will not pass through the filename for you to be able to insert into a table.
You will need to have a controlling o/s script that picks up the file name, calls sql*loader and then also call's an SQL script (using sql*plus?) to insert the filename into a.n.other table.

Should I load properties and or preferentces into a hashmap??
