What does it mean by $scope=global in ATG..?

According to the documentation,
Global: Component is shared among all users.
Session: Separate instances of the component are provided to each user.
Is that means, for global component, there is only one instance for the whole nucleus system..
If this is true, how does it valid for components like ‘/atg/dynamo/transaction/TransactionManager’ and most of the droplets..?
Because those components are used by several users at a single moment..
Edited:
I understood the ‘TransactionManager’ behavior. According to the definition there should be single transaction manager, and he should keep transaction objects per each transaction. But my question is still valid for droplets like, foreach, switch, etc (most of them are globally scoped) If there is only one instance of corresponding class for the whole nucleus system, isn't it having bad effects on performance?

Hi,
The term 'scope' refers to component and not the class.
So, global components will be instantiated only once (load the class file -> create the component -> initialize the values from the properties file).
Droplets are meant to be used across the applications and so no need to instantiate the components more than one time. Also they serve the same purpose even if we do so.
Hope this helps.
Keep posting the questions.
Thanks,
Gopinath Ramasamy

Ever since the 6.0.2 update - every single day there's been something new going horribly wrong. For the past couples weeks it has been the browser hanging or crashing for no apparent reason and now this error hitting the browser screen over and over a hundred times a minute. I've used firefox since it began and NEVER had any issues previously. This 6.0 upgrade is a downgrade and is making me seriously look at Chrome (never IE - why I switched to firefox), though making the switch will be a pain due to all the apps I rely on and thousands of bookmarks that would need to be transported. Please mozilla fix this because using this browser has suddenly gone from seamless to frustrating pretty much overnight!

thank you thank you for taking an interest. this is so frustrating.
i only have apple keyboard, mighty mouse, and 20 inch cinema display connected. this morning took out memory and tried to boot up with individual pairs in the first bank. first the (2)256, the (2) 1g, and then the other (2) 1g modules. everytime I get the weird fuzzy wheel under the logo after a while, black screen flashes, then grey apple logo fuzzy screen then black forever.
I ran tiger updates this morn. still will only boot to safe mode. then tried to run leopard disk to install it
will not boot from leopard disk.
tried safe boot, then doulble click install leopard, restart, then the saga repeats with the pixely red square around the wheel.
these are fresh drives with only what came on instll disk loaded.
thanks again for taking an interest.
i love this system(well at least i did). I want to install leopard on my powerbook too but am terrified to do so right now since it is working and I have work to do. Can't afford to have no computer to do my work on...self employment is great?!
This is making me crazy. I anxiously await your words of wisdom.

GetResponseCode() returns -1,what does it mean

Hi ,
The HttpURLConnection class's getResponseCode() method returns -1.
getResponseMessage() returns null.i m accessing my servlet through a proxy.i know only about 1xx to 5xx codes.i dont know what does it mean by -1.But at server side the request is properly sent and processed and i m getting 200 and ok after processing at serverside. the object is sent to client also. but it is not received by the client.
Null object is returned.I think proxy is the culprit.If anyone can help me what -1 means,it will be really greatfull to diagnoise my issue in detail and solve my problem soon.
Your help will be greatfull.
Thanks
prakash

As it says perfectly clearly, right there in the API documentation for the method:
"Returns -1 if no code can be discerned from the response (i.e., the response is not valid HTTP)."

Why has my monitor suddenly begun to have a moiré pattern all over – it is even showing up on my icons on the dock? It appears to be very thin bright green vertical lines. I have a 2007 iMac which is running 10.6.8. What does this mean? I've attached some screen shots below.
Also experiencing some funky issues with my wireless keyboard. With new batteries, it will just stop functioning. Certain keys intermittently won't work. Also the fans go on as soon as I turn the computer on - some times they stay on and sometimes they don't. Ever since upgrading the operating system - I've been having many issues with this iMac. Not happy. Any answers out there?

Thanks for your reply LexSchellings, There is no disc in the drive and I went through the suggestions you put forward on the phone with Apple support without any luck. I can put a disc in but it pops straight back out again without registering on finder.
The idea of using an external drive was to enable me to avoid the cost and loss of productivity whilst machine in repair... if I have to take it in to get the old drive removed than I might as well have a new internal drive put in, although I do worry about the reliability of these apple drives given my experience with this one coupled with my limited online research ... on line forums seem to be full of people with the same problem (although perhaps searching such forums is bound to make it seem a common problem as users with perfectly working machines are less likely to post (?)) Your reply suggests that no external drive will work whilst the existing drive is in place.
As a postscript: I do realise that this is a user forum ...my secondary question was asking if anyone knows how to put forward a case/complaint to Apple... I can't find a link on the support page that would enable me to do so and I was wondering if anyone on this user forum had any ideas/experience..

When I click to pay my songs in the library they will not play and it shows a circle with an exclamation point within it. What does that mean, how do I fix it, and how will it play my songs again? They used to play before on my Iphone4 with no problem, but since I upgraded to the Iphone4s there is an issue.

I am having the same problem. I have just tried this. Unplug iphone > open itunes > delete all music from itunes library > close itunes > re-open itunes > add music from original folder > plug in iphone > select songs > press sync > unplug iphone using eject button onscreen > checked phone .... still nothing in music folder on phone. On itunes the "On this iphone" tab the songs remain there but greyed out.
