Hi, would anyone tell me what is the difference between JRE and SDK?

So which one I should download and install on my computer so that I can do some programming?
Thanks for help

JRE is used to run the programs, SDK is the SofwareDevelopmentKit or something like that. So for programming you need the SDK (contains the JRE too). For running the programs you need the JRE.

Could any one tell me what is the difference between swfloader and module loader?

Hi All,
                      Could any one tell me what is the difference between SWFLoader and Module Loader in Flex3 in detail?

Hi,
ModuleLoader is a kind of strange API that is really just intended to look like SwfLoader for modules that contain a single visual component, and hides most of the module loading infrastructure, which is all about class factories.
What I mean by "only loaded once" is that if you have several places in the code that call the ModuleManager.getModule("url").load() call, it will only ever get loaded over the wire and interpreted once, subsequent "loads" will just re-dispatch pseudo-load events to the new client. In other words, the class factory is a singleton for a given url. Unloading is a totally different story. As you note, not everything is truly unloadable, because there may be lots of references to stuff in
the module that will keep it alive and un-GC'ed.
I suggest playing with the low-level API so that you understand the backing implementation, and this should help you understand the limits of ModuleLoader.
The main difference between modules and applications is that modules have lower overhead, and they only ever get loaded once, no matter how many times you load them. If you're using the ModuleLoader API, keep in mind that you're losing about half the functionality of the module system. I will assume that you are, because otherwise it would be obvious where to expose methods. You might want to play around with the lower level ModuleManager API just to get a hang of what's going on - ModuleLoader is a pretty thin veneer over the lower API.
                Basically, what you want to do is to have your module implement an interface, say IModuleWhatever.

Where can i find HotSpot for Solaris?
tks!

The difference between the two is explained at:

It's included in the J2SE v1.3.1 release.

What are the differences between jdk and sdk

what are the differences between jdk and sdk?? thanks

Just marketing whims.
SDK = software development kit
JDK = Java development kti
Sun has use both names to refer to its SDK for Java. I forget which one they're using now, but they've switched a couple of times.

What are the differences between api and sdk

Hi,
Could anybody clarify for me what are the difference between API and SDK? I googled for the answer, and couldn't find any thing on this topic.
Many thanks in advance.

Is it correct to say that "a SDK includes all the
APIs"? or "API sits on top of the SDK"?It's a bit weird to say either. First, the JDK doesn't include all APIs. Just the J2SE core API. Others, like 3rd party libraries or J2EE are not included. Second, if you mean the API docs, they're also not included IIRC.
It'd technically only be correct to say "the SDK provides an API", I guess. The example is very lame, but: if the SDK is a machine, the API is the sum of its buttons and levers and gauges and intakes and outlets and exhausts. The API docs are the manual.

Hi can some tell me what is the difference between sapr3 and sap business 1

is there any difference between sap business one and sap r3 if i learn sd module

Hi Siva,
The SD module from R/3 is completely unrelated to the business processes and technologies used in SAP Business One (SBO). R/3 and SBO are completely different products and direct comparisons are difficult. I don't think learning one will help in any degree in learning the other. With R/3 you tend to specialise in one area (eg SD) as the complexity and scale of implementations requires this specialisation. With SBO, a single consultant would be expected to know the whole product. SBO is a much simpler product designed for small to medium sized companies so the processes are much more generic.
Kind Regards,

What are the differences between inactive and active ABAP objects?

Can anybody tell me what are the differences between inactive and active ABAP objects?
In my opinion, an active object is compiled and system wide available, that means the system do not have to compile the program again before run or use the object. While An inactive object is not system wide available and every time you run an inactive object, firstly the abap runtime will have to generate a tempory runtime object and this inactive object can not seen by others.
Am I right? Can anybody kindly tell me other differences?

Hi,
"When it is inactive, it is like it would not exist at all:" no - it's like it only exists to you
"If we just saved that one means it is stored in application server not in database": no - the inactive version is also stored in the database. You can log off and log on and it will still be there, in its inactive status.
"Only active objects can be executed.": no - inactive objects can be executed by you
When you create or modify a program, it is inactive until you activate it.
With a change, there are two versions of the program stored in the database - the active version (as it was before you made your change), and the inactive version. If you attempt to run the program, you'll run the inactive version - the one with your changes. Everyone else on the system will run the active version.
In this way, you can make changes without affecting anyone else.
Once you activate your program, then the inactive version becomes the active version.
With a create, there is no active version, until you hit the activate button. This means ONLY you can run the program.
An additional benefit of this model, is that if you make a change, save it, and then change your mind without activating, you can recover the active version into the editor, using version management.
A downside is that sometimes you have to activate your change before you can test it, if it interacts with other, active, programs.

Kumar

What's the difference between jsp and jsf?

who can tell me what's the difference between jsp and jsf?
I'm puzzled when I found some of the technology in jsp is so similar to the ones in jsp( javaserver page)

Hi,
Find the difference between JSP and JSF
1. A developer has more control with JSP, but (should) get easier development with JSF
2. Event handling is done differently in JSP (HTTP) and JSF (Java)
3. The UI is designed differently (or should be at least) with JSP (markup) and JSF (components).
4. The end product should also be defined differently - JSP page versus a JSF application.
Is this the only thing that is need to make a decision for either or? Probably not. There are other pieces that need to be taken in account when deciding which technology to use - tools support, enough components, type of application etc.... At this point there are not enough JSF components (although there are some interesting projects underway - Ajaxfaces, Myfaces, ADF Faces, and WebChart 3d) and enterprise tools support is still limited to a few tools vendor. Looking at our ADF Faces components they are currently available as early access (not production) and demands for these components are stacking up, literally, outside my office doorstep. Although I would love to make them production - now! - it is not a viable solution since we are still checking features and fixing critical bugs.
All this combined - not enough enterprise level components in production, lacking tools support etc... - leave customers in a vacuum where the decision is either to continue with JSP, since it is mature and has a wide developer base, or move forward with JSF not sure if the support, or the developers will be there. This is particularly sensitive to customers that need to get started now and be production by summer.
If you are in this vacuum here are some key points promoting JSF:
1. Fundamental unit is the Component
2. Built in event and state management
3. Component sets can be provided by any vendor
4. Closer to ASP.Net or Swing development
5. Choice of UI technology
6. Scale up (rich clients)
7. Scale down (mobile devices)
8. Built into J2EE containers in J2EE 5.0 (tentative)

Hi Tiffny,
actually I don't see a difference as "mySAP2004" is not an official name for anything
There is "mySAP ERP 2004" which is the marketing name for a bunch of functionality provided by several different bits of software components.

What is the difference between DSo and Infocube

Hello,
Kindly tell me what is the difference between DSO and Infocube?
And please tell me how to take the desicion that in whichi case we can use DSO and in which case we can use Infocube..

Hi ,
DataStore object serves as a storage location for consolidated and cleansed transaction data or master data on a document (atomic) level.
This data can be evaluated using a BEx query.
A DataStore object contains key fields (for example, document number/item) and data fields that can also contain character fields (for example, order status, customer) as key figures. The data from a DataStore object can be updated with a delta update into InfoCubes and/or other DataStore objects or master data tables (attributes or texts) in the same system or across different systems.
Unlike multidimensional data storage using InfoCubes, the data in DataStore objects is stored in transparent, flat database tables. The system does not create fact tables or dimension tables.
Use
The cumulative update of key figures is supported for DataStore objects, just as it is with InfoCubes, but with DataStore objects it is also possible to overwrite data fields. This is particularly important with document-related structures. If documents are changed in the source system, these changes include both numeric fields, such as the order quantity, and non-numeric fields, such as the ship-to party, status and delivery date. To reproduce these changes in the DataStore objects in the BI system, you have to overwrite the relevant fields in the DataStore objects and set them to the current value. Furthermore, you can use an overwrite and the existing change log to render a source delta enabled. This means that the delta that is further updated to the InfoCubes, for example, is calculated from two successive after-images.
An InfoCube describes (from an analysis point of view) a self-contained dataset, for example, for a business-orientated area. You analyze this dataset in a BEx query.
An InfoCube is a set of relational tables arranged according to the star schema: A large fact table in the middle surrounded by several dimension tables.
Use
InfoCubes are filled with data from one or more InfoSources or other InfoProviders. They are available as InfoProviders for analysis and reporting purposes.
Structure
The data is stored physically in an InfoCube. It consists of a number of InfoObjects that are filled with data from staging. It has the structure of a star schema.
The real-time characteristic can be assigned to an InfoCube. Real-time InfoCubes are used differently to standard InfoCubes.

What is the difference between StringBuffer and StringBuilder objects

hi ,
Please tell me what is the difference between stringBuilder and stringBuffer classes ..why stringbuffer classes is used more with multiple threads but not stringBuilder which is faster than stringBuffer objects
Thanks in advance

Odd. You answer your own question by paraphrasing the first paragraph of
StringBuilder's javadoc:
This class provides an API compatible with StringBuffer, but with no guarantee
of synchronization. This class is designed for use as a drop-in replacement for
StringBuffer in places where the string buffer was being used by a single thread
(as is generally the case). Where possible, it is recommended that this class
be used in preference to StringBuffer as it will be faster under most
implementations.
Do you really have a question?

Why would i connect a external hardrive to the airport extreme and what is the difference between LAN and WAN gigabit ethernet?

Hey just wanted to know what is the reason i would connect my external hardrive to the extreme and what is the difference between LAN and WAN ehternet. I know one is local and other is wide but can someone explain in simpler terms.

Connecting a hard drive to the Airport Extreme makes it available to be shared across all the computers on your network.
WAN (Wide Area Network) is your connection to the internet
LAN (Local Area Network) is your internal (or local) ethernet connections (computers, printers, etc...)

What is the difference between Firefox and Firefox os please. I have a Samsung galaxy s3 mini what one would you recommend would be better for my phone

What is the difference between Firefox and Firefox os, and what one is better for the Samsung galaxy s3 mini, Please could you recommend which one is the best and most suitable for my phone please. Many thanks Michelle Petch

Thank you for your question.
Firefox is basically a browser.And Firefox OS is an Operating System.You can install Firefox in your SGS3 just like an android application.But if you want Firefox operating system on it. then you have to flash the ported Firefox OS on your device. Then it will be a completely different standalone operating system.you cannot install android applications on it.
To read more technical difference read:
Firefox OS:

Firefox Browser:

Hope this clears your query.Thank you

What si the difference between crete and create insert operations.

Hi
In ADF 11g,what is the difference between create and createinsert operations.
if anyone knows plz tell me.Any document about this plz provide me.
Any help is appreciated.
Sailaja.

Hi,
CreateInsert: Creates a new row that becomes the current row, and inserts the
new blank row into the data source.
Create: Creates a new row that becomes the current row, but does not insert it.
--> normaly you would use createinsert
Doc you can find here (search for Createinsert): http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974.pdf
