What is exact diff between Bean and Class

As my knowledge...
Class should not depends on any specified rules..But Bean should specified on specified rules, like setters and getters....
is there any more........
thanks for giving help..........

Yes, but what are they good for, except for providing
examples of really bad OO design by just being a
complicated struct?Look at Spring; an extremely powerful application configuration tool (and much, much more); all possible because of JavaBean conventions. Otherwise Spring would have had one set of conventions, JSF another, Hibernate another still, making programmers' lives difficult.
Look at the PropertyEditorSupport class - it's fantastic that I can write a standardized String-to-instance-to-String class for a particular type and just have frameworks like Spring take care of the problems generating my domain model from configuration. Using a standard mechanism makes me confident that if, in the future, I ditch Spring, my bespoke property editors will not be obsolete.

What is exact difference between table and template in script

hello all
what is exact difference between table and template in script

Hi there.
Tables alow you to achieve more complex flows with internal tables. You can use different types os lines, like footer, header, line items, and differente types of line items. Also, and most important, you have different processing blocks, again header block (processed before processing of first row), body block (rows) and footer block (after last row or page break).
If you don't need any of this, use a template inside a loop to achieve something like a table. I personaly use templates only to draw lines, for example, before and after a loop, or to align some header in my documents.
A table, is a loop and template mixed to become a very good tool.

What is exact diffrence between Error and Exception

what is exact diffrence between Error and Exception....and also give me
definitions.....i would very thank full to given answer to me.

Error may or may not be handled by the compiler or JVM there are many errors like Assertion error,stack over flow error out of memory error etc..
Exception is the abnormal condition and these may be handled by the compiler.There r many exceptions like clone not supported, interrupted exception,i/o exceptions...Exception can be handled by using try catch blocks.

What is the diff between replication and streams

Hello,
Can some one tell me the difference between replication and Oracle streams, When I look into the documentation, it says to use the Oracle EM Console to setup the Replication.But I am not sure how do I download the Oracle EM Console.
Thanks for all who replies for this.

Replication is a Neolithic, perhaps Paleolithic, technology that slightly improved replication over what we did back in the days when we lived in caves and spoke only using grunts and hand motions.
Replication is hard to set up, hard to maintain, and essentially guaranteed to give you full-time employment and loss of hair due to gaps created by transactions that do not replicate correctly and network issues.
Streams is far from perfect but is vastly superior in terms of flexibility, gap resolution, and performance.
When looking at Streams also look at Change Data Capture (CDC). If CDC will do the job don't do Streams directly. Use the simplified API.

What's the diff between ThreadPoolRuntime and WorkManagerRuntime?

I'm trying to get a better understanding of the metrics I can retrieve from the JMX MBeans deployed by default. Can someone tell me what the difference is between the only instance of a weblogic.management.runtime.ThreadPoolRuntimeMBean in our managed server and the various weblogic.management.runtime.WorkManagerRuntimeMBean instances for each of our EARs (as well as for weblogic.system.Kernel)?
Does the ThreadPoolRuntimeMBean represent all of the JVM-level threads that each of the WorkManagers use? If so, would I be safe in assuming that the value of the 'CompletedRequests' attribute on a WorkManagerRuntimeMBean could NEVER be greater than the value of the 'CompletedRequestCount' attribute on the ThreadPoolRuntimeMBean at any given time?
Using an example, let's say that I have WorkManagerA, WorkManagerB and the weblogic.system.Kernel WorkManager. If I got the following values:
WorkManagerA.CompletedRequests = 5
WorkManagerB.CompletedRequests = 6
WorkManager[weblogic.system.Kernel].CompletedRequests = 4
then should I have a ThreadPoolRuntimeMBean.CompletedRequestCount >= 15 ?
Any tutorials would be greatly appreciated.
Cheers!

FYI, I have been testing this theory for the past week and my assumption appear to be true.

What is exact difference between PPM and PDS

Hi,
can any one prove details of Difference between PPM and PDS
Thanks
suresh

Dear Suresh,
please find below the detailed comparative account of PDS Vs PPM. You can copy and put it in an excel sheet in different columns and then read which is easy to understand.
PDS:
1. Production Data Structure (PDS) in APO 3.1 & Run Time Object (RTO) in 4.0 and above versions
2. Master Data Object
3. Useful for scenarios where the compoenent has got different validity periods
4. Used as Master data Basis for Planning in SAP-APO
5. Contains active Master data from iPPE (Integrated Product and Process Engineering) generated from a production version
6. PPDS PDS & SNP PDS can be used as master data for planning
7. Change Management, variant configuration & Phantom assemplies are supported in PDS
8. Sub-contracting in SNP is fully integrated with R/3 is supported in PDS
9. Direct transfer of SNP PDS from R/3 is possible
10.Rapid Planning Matrix can be generated
11. Not possible to maintain PDS directly in APO and can be used only in combination with R/3
12. The transfer of data changes is simpler
13. Not possible to create alternate SNP-PDS in std system for different mode combinations
14. PDS can be automatically generated from two sources ie R/3 and iPPE
PPM:
1. Production Process Model
2. Master Data Object
3. Cannot be used for scenarios where the component has got different validity period
4. Used as Master data Basis for Planning in SAP-APO
5. Contains active Master data generated from the combination of routing (BoM & receipe) and production versions
6. PPDS PPM & SNP PPM's can be used as master data for planning
7. Not supported by PPM
8. Not supported by PPM
9. Not possible here. SNP PPMs will be generated via PPDS PPMs
10. Not possible
11. PPMs can be directly created in APO and can be modified without R/3 also.
12. Little Complex when compared to PDS
13. Alternate SNP-PPMs can be easily created
14. PPM can be generated automatically generated only from R/3

What is the diff between jsp and servlet

is thr any other difference betwwen jsp and servlet, tht: jsp is automatic generated servlet and jsp has different types of tag, due this we have write less amount of code.any other technically difference between these two?

As you mentioned JSP automatically gets converted into a Servlet and then compiled. From the server's perspective other than the transformation process, there is no real difference.
However, in coding there are some minor differences such as additional access to pre-defined variables and different syntax for some minor things such as imports and etc.
Perhaps somebody else more knowledgeable can fill you in further.
Hope that was helpful.

What's the diff between Excluding and Removing?

The Help docs don't seem to mention this. In Sys Prefs > TM > Options, in the first window you can select a folder and click to remove it from the list. Or you can click which brings up a find window where you can go to a folder or file and Exclude it. Anyone know the difference and if one is preferred over the other?
You can also Show Invisible Items. If you want to limit your disk usage, should we Exclude things like mach_kernal, private, sbin, tmp, usr, etc?

sorry, don't really understand the question. + is for adding items to the TM exclusion list, - is for removing them from that list.
You can also Show Invisible Items. If you want to limit your disk usage, should we Exclude things like mach_kernal, private, sbin, tmp, usr, etc?
you could. when you exclude one system file TM will offer to exclude all system files which includes all the files you mention so you don't have to do it one by one. However, due to incremental nature of TM backups this will save you about 10GB TOTAL on the TM drive. Entirely not worth it IMO given that this will make it impossible to restore your entire system from backups.

Diff. between currency and unit fields

Hi All,
What is the diff. between 0DOC_CURRCY and 0CURRENCY, OUNIT and 0BASE_UOM? In which scenarios do we use each of them?
I have a flat file which contains some values for sales and quantity but does not have any units. So I have to upload them using constant currency and unit. now, I have to create my own keyfigures for the sales and quantity. What currency and unit fields should I use i.e 0CURRENCY or 0DOC_CURRCY and OUNIT or 0BASE_UOM?
Thanks a lot,
James.

hi James,
0doc_currency, 0currency share the same master data->0currency, 0unit, 0base_uom share the same master data->0unit, the 'basic' infoobject is 0currency and 0unit, all currency and unit will have reference to these infoobjects.
currency is used for keyfigures amount, with currency e.g usd, gbp, etc.
unit for keyfigures quantity, with unit like KG, CM etc.
currency tables are TCUR* and unit table T006*
you can use any of these infoobject currency or unit in your keyfigure (RSD2) or fix value like USD etc, normaly 0doc_currcy used for document currency; 0loc_currcy for local currency, you can create your own infoobject currency/unit with RSD3.
hope this helps.

What is the difference between TECO and Order settlement?

What is the diff. between TECO and order settlement and what is the use of both?

Hi,
Technical completion means ending a production order from a logistical viewpoint. This function is usually used, if the execution of an order has to be stopped prematurely or if the order could not be executed in the required manner and open requirements for the order (reservations, capacities) should be deleted.
Where as Settlement of an order is carried out periodically to settle the costs related to the order to a settlement receiver.

What is the difference between thread and task

hi ,this is guruvulu bojja
what is the diff between thread and task .
can u give me the example for distinguish a thread and a task .
How can i know thread is better than a task .
please tell me what is the task in o/s level and task.
how the o/s distinguish a therad and task.

Hi Guruvulu,
Threads enhance performance and functionality by allowing a program to efficiently perform multiple tasks simultaneously.
In the case of common memory threads naturally have shared data regions while it has to be specially created and initialized for tasks.
Simply put, a thread is a program's path of execution. It allows execution of two or more sections of a program at the same time.

Pooja.
