Can some one explain me oracle MVC configuration or point me to a guide

I use oracle MVC in my application. cle20.jar is used for it. The application was working fine and now all of sudden I get a null pointer exception in my code where i use this line of code: "ProcessInfo info = (ProcessInfo)getInfo(aKey);" where getInfo is from the oracle.cle.process.GenericProcess and aKey is not null.
Any help or direction will help. I debugged the application and see that getInfo is always returning null value for all values of aKey.
Error Message is as follow:

Can some one explain me on Exchange server / CAL licesing & where I can find current cost information?

Hi,
As far as I know, every user need a license to use Exchange server and we can choose User CAL or Device CAL.
For more information about license, you can refer to the following articles:
Licensing Basics: What are CALs (Client Access Licenses):
http://blogs.msdn.com/b/mssmallbiz/archive/2007/11/06/5942350.aspx
Exchange Server 2013 licensing:
http://office.microsoft.com/en-001/exchange/microsoft-exchange-server-licensing-licensing-overview-FX103746915.aspx
Exchange Licensing FAQ:
http://office.microsoft.com/en-001/exchange/microsoft-exchange-licensing-faq-email-for-business-FX103934581.aspx
For the cost issue, I recommend you call Microsoft Licensing for useful information. And they will be able to give you an estimate based on your requirement.

If you have any question, please feel free to let me know.

How come extend is the physical structure ? Can some one explain.

How come extend is the physical structure ? Can some one explain.
thanks
siva

"Tablespaces physically group schema objects for administration convenience. They bridge physical structures, such as datafiles or extents, and logical structures, such as tables and indexes. Tablespaces can store zero or more segments. Segments are schema objects that require storage outside the data dictionary. Tables and indexes are examples of segments. Constraints and sequences are examples of schema objects that do not store data outside the data dictionary and are therefore not segments." - Study Guide.
Read above, it reads "physical structures, such as datafiles or extents", this is where I got confused ?
thanks

Hi frnds...im new 2 BI can some one explain me basics in BI...

HI frnds..
I jst started BW/Bi training..can someone explain me basics in BW.. like
what are dimesion id's n surrogate id's??
what is extended schema???
what is master data??
how master data is stored??
what is datasource,infosource,infopackage,application component,transfer rules,update rules....have much confusion..
please can some one clear it...

First of all this is not the correct forum for your questions. This forum handles questions regarding the BusinessObjects on Demand offering.
Secondly it is not realistic to expect an answer to ALL those questions in a forum. I would suggest either to buy book about SAP Netweaver/BW (Beginner's level) or search for the keywords you are refering to either in SDN or in the Internet. There are some SAP BW tutorilas available out there.
eg.

Can some one explain each line of this abap code

Hi..
I got this code from a document, where they try to add account group (LFA1-KTOKK) to 0VENDOR_ATTR. I have no idea of ABAP syntax. Can some one tell me the meaning of each line of code.

 data: l_s_BIW_LFA1_S like BIW_LFA1_S.
 loop at i_t_data into l_s_BIW_LFA1_S.

 select single * from lfa1 where LIFNR = l_s_BIW_LFA1_S-LIFNR.
 if sy-subrc = 0.
 l_s_BIW_lfa1_s-ZZacctgrp = lfa1-ktokk.
 modify i_t_data from l_s_BIW_lfa1_s index l_tabix.
 endif.
 endloop.
 endcase.
 endcase.
Thanks in advance.

Hi

Deadlock - can some one explain pls?

public class Lazy {
 private static boolean initialized = false;
 static {
 Thread t = new Thread(new Runnable() {
 public void run() {
 initialized = true; // Deadlocks here
 t.start();
 try {
 t.join();
 } catch(InterruptedException e) {
 throw new AssertionError(e);
 public static void main(String[] args) {
 System.out.println(initialized);
}The above given program deadlocks at the point specified in comment. Can someone explain the reason for this? Thanks in advance

Sounds reasonable. But I do also expect some voodoo
magic to be involved since the posted code isn't
synchronized.If I understand the few lines of the VM Spec correctly, the above would lead to:
public class Lazy {
 private static boolean initialized = false;
 static {
 Thread t = new Thread(new Runnable() {
 public void run() {
 // <VM>
 if( !Lazy.class.ready() ) {
 synchronize( Lazy.class ) {
 // Do Lazy init
 // </VM>
 initialized = true; // Deadlocks here
 t.start();
 try {
 t.join();
 } catch(InterruptedException e) {
 throw new AssertionError(e);
 public static void main(String[] args) {
 // <VM>
 if( !Lazy.class.ready() ) {
 synchronize( Lazy.class ) {
 Do Lazy init
 // </VM>
 System.out.println(initialized);

Well, the obviously solution is to use separate Apple ID's for iCloud.

Can some one please tell me what is the problem in the below pl/sql block

Hi, I have problem with the following pl/sql block, I need this with bulk operation.
-- Assume the following scenario, we are validating dept (master) and emp(child) which are my temporary tables and updating the status back to
-- dept ( for all the validation errors, even if we have any validation at child it has to update the header record with error message),
-- upon successful validation insert the data into dept3, and emp3 interms of batches
-- I have give the sample example with dept and emp, but i have around 10 million records which has around 30-40 validations,
-- I would like to process them in terms of batches using bulk collection as this would do fast processing
-- Can some one please tell me how to insert them in terms of bulk with every set of 1000 records in each batch in this example,for every set of 1000 records
-- i need update batch id with unique number in dept table
-- with current data i can have 50 batches , I need to pass, deptno as parameter to my emp cursor.
-- can some one please tell me how to make this validation and insertion more efficient. so that while inserting the data for every batch it should insert batch id
-- Tried with LIMIT clause as well but not working
-- I am correcting the code as per your comments Request you to please suggest me so that I can correct , I am new to PL/sql, started learning now.

Hi, I have problem with the following pl/sql block
Well, as Hoek already said, that is the understatement of the century.
I can't be absolutely certain but I think that set of DDL and code that you posted has just about every possible error and design issue that there is! It would make an excellent addition to BluShadow's FAQs an an example of what NOT to do.
I don't think it is even possible to 'fix the basics first' as Hoek suggested. IMHO the first step needs to be to create a functional requirements document (FRD) that explains in detail WHAT needs to be done. That doc should also contain info about how any errors/recovery/restart is to be handled. It is premature to try to implement ANY solution without first knowing what is needed functionally.
Once the FRD is done you should do a walk-through based on your current architecture and sample data to make sure that the document really covers ALL of the steps that need to be performed and that it adequately explains how to deal with any processing or data issues that might arise.
The next document you need is the TRD - Technical Requirements Doc that covers the different technical implementions of the FRD that can be done and the advantages/disadvantages of each.
Then you can start working on a prototype.
1. The DDL you posted isn't coherent - there are CREATE table statements and then later ALTER statements that add additional columns. There doesn't appear to be any reason for not including ALL of the columns in the CREATE table statement.
2. You are using PL/SQL types instead of SQL types. That makes it impossible to use those types in SQL statements and makes it much more difficult to test since it is much easier to test a query in SQL (e.g. using sql*plus) that to embed the query in PL/SQL.
3. You are defining the same type twice but giving it different names.
TYPE dept_t
 IS
 TABLE OF dept%ROWTYPE
 INDEX BY binary_integer;
TYPE dept_i_t
 IS
 TABLE OF dept%ROWTYPE
 INDEX BY binary_integer;
Those are both based on the same DEPT table! Why the duplication?
Also you are using associative arrays instead of just using nested tables. Get rid of the INDEX BY clause.
4. You have some serious architectural and data model issues
-- Assume the following scenario, we are validating dept (master) and emp(child) which are my temporary tables and updating the status back to
-- dept ( for all the validation errors, even if we have any validation at child it has to update the header record with error message),
Why would you do that? You say 'it has to update the header record ...'. Says who? That is just one indication that you are trying to implement a 'solution' before you have adequately defined the 'problem'.
Typically you would NOT alter any of the data tables; any validation errors/issues would get inserted into a table specifically designed to hold/log those issues. That table would contain key field values to correlate with the source of the error.
Those 'master' and 'child' entities are two SEPARATE things. Issues with a 'master' row have NOTHING to do with any possible child rows.
And issues with a 'child' row have NOTHING to do with any possible master rows. The ONLY connection between 'child' and 'master' is the foreign key that correlates them.
So you don't necessarily have to validate the 'child' rows in sync with their 'master' row. In many cases you would have a procedure that performs validation of the entire set of 'master' rows and log those issues/problems. You would use a different procedure to validate the entire set of 'child' rows and log their issues.
Those validation procedures can often work with ALL of the data using SQL statements instead of bulk processing.
5. You are using loop constructs that are not valid for the type of processing you are using
LOOP
 FETCH c1 BULK COLLECT INTO hdr_tbl;
 EXIT
WHEN c1%NOTFOUND;
END LOOP;
There can be NO exit since the bulk collect with either get EVERYTHING or NOTHING. Possibly that is just a holdover from your attempt to use the LIMIT clause but you removed that clause from the FETCH; I don't know.
There is so much wrong with what you posted it is really rather pointless to try to 'fix' it.
I suggest you start over and clarify and DOCUMENT the actual requirements without prejudice about the solution that someone seems to want to force on you.

Hi...
Thanks for your repaly .
and i am not bale to post a question in developer forum i tried hard but i didnt get .Can you plz explain me how to post a question in developer forum this is very helpfull for me.Because i never did this thing.

Please please can some one tell me how do you charge ur ipad with ur laptop. it doesn't chage wen I put use the wire. only charges when I plug the socket in.

please please can some one tell me how do you charge ur ipad with ur laptop. it doesn't chage wen I put use the wire. only charges when I plug the socket in. Iv never used an ipad b4 so don't really know much. Hope some one knowz.

The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Can any one explain me about Listeners in Java

Hi,
Can any one explain the Listeners concept in Java??
Will that work like net send in Windows NT??
How can we achieve the net send type of messaging in an Intenet application??
Is there any possibility??
Please help me out...
Thanks in advance,
Chaitanya.

The idea is that the "observable" object holds a list of listening classes which conform to a given interface. When an event occurs it walks the list calling a specific method in all the listeners with whatever parameters are suitable to speficy the event. Very often the listeneing objects are inner classes of some larger class which implement whatever effect the event is to have on the larger class.
Anyonymous inner classes are a convenient abbreviation here.
Usually the observable class has methods called add???Listener and
remove???Listener to add and remove listeners from it's list. There's also often a protected method called fire???Listeners (where ??? is the event type).
So for instance:
public interface DirtyListener {
   public void dirtyChanged(boolean to);
class DataModule {
   private Set dirtListeners = new HashSet(10);
   public void addDirtyListener(DirtyListener d) {
      dirtListeners.add(d);
   public void remiverDirtyListeners(DirtyListener d) {
      dirtListeners.remove(d);
   public void fireDirtyListeners(boolean to) {
      Iterater it;
      for(it = dirtyListeners.iterator(); it.hasNext();)
         ((DirtyListener)it->next()).dirtyChanged(to);
class ObservingClass {
    DateModule data = new DataModule();
    data.addDirtyListener(new DirtyListener() {
      public void dirtyChanged(boolean to) {
        saveButton.setEnabled(to);

Can any one explain me about Field symbols in Genral Reports?

Can any one explain me about Field symbols in Genral Reports?
If possible, plz explain me with the code to explain me about the field symbols.
Regards,
Krishna Chaitanya

Syntax
FIELD-SYMBOLS <fs> { typing | STRUCTURE struc DEFAULT dobj }.
Extras:
1. ... typing
2. ... STRUCTURE struc DEFAULT dobj
Effect
The FIELD-SYMBOLS statement declares a field symbol <fs>. The naming conventions apply to the name fs. The angle brackets of the field symbols indicate the difference to data objects and are obligatory. You can declare field symbols in any procedure and in the global declaration section of an ABAP program, but not in the declaration section of a class or an interface. You can use a field symbol in any operand position in which it is visible and which match the typing defined using typing.
After its declaration, a field symbol is initial - that is, it does not reference a memory area. You have to assign a memory area to it (normally using the ASSIGN statement) before you can use it as an operand. Otherwise an exception will be triggered.
Addition 1
... typing
Effect
You can use the addition typing to type the field symbol. The syntax of typing is described under Syntax of Typing. The typing specifies which memory areas can be assigned to the field symbol (see Checking the Typing) and in which operand positions it can be used.
Note
You can omit the addition typing outside of methods. In this case, the field symbol has the complete generic type any and is implicitly assigned the predefined constant space during the declaration.
Addition 2
... STRUCTURE struc DEFAULT dobj
Effect
If you specify the addition STRUCTURE instead of typing for a field symbol, and struc is a local program structure (a data object, not a data type) or a flat structure from the ABAP Dictionary, this structure is cast for the field symbol <fs>. You have to specify a data object dobj that is initially assigned to the field symbol.
The field symbol copies the technical attributes of structure struc as if it were completely typed. When you assign a data object using the addition DEFAULT, or later using ASSIGN, its complete data type is not checked in non- Unicode programs. Instead, the system merely checks whether it has at least the length of the structure and its alignment.
In Unicode programs, we differentiate between structured and elementary data objects. For a structured data object dobj, its Unicode fragment view has to match the one of struc. In the case of an elementary data object, the object must be character-type and flat, and struc must be purely character-type. The same applies to assignments of data objects to field symbols typed using STRUCTURE when using the ASSIGN statement.
Note
Field symbols declared using the addition STRUCTURE are a mixture of typed field symbols and a utility for casting structured data types. You should use the additions TYPE or LIKE for the FIELD-SYMBOLS statement to type field symbols, while the addition CASTING of the ASSIGN statement is used for casting.
Example
The first example shows the obsolete usage of the addition STRUCTURE.
DATA wa1 TYPE c LENGTH 512.
FIELD-SYMBOLS <scarr1> STRUCTURE scarr DEFAULT wa1.
<scarr1>-carrid = '...'.
The second example shows the replacement of STRUCTURE with the additions TYPE and CASTING.
DATA wa2 TYPE c LENGTH 512.
FIELD-SYMBOLS <scarr2> TYPE scarr.
ASSIGN wa2 TO <scarr2> CASTING.
<scarr2>-carrid = '...'.
Also,
Field Symbols
Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field symbols are similar to dereferenced pointers in C (that is, pointers to which the content operator * is applied). However, the only real equivalent of pointers in ABAP, that is, variables that contain a memory address (reference) and that can be used without the contents operator, are reference variables in ABAP Objects.
All operations programmed with field symbols are applied to the field assigned to it. For example, a MOVE statement between two field symbols moves the contents of the field assigned to the first field symbol to the field assigned to the second field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks the compatibility of the field symbol and the field you are assigning to it during the ASSIGN statement.
Field symbols provide greater flexibility when you address data objects:
If you want to process sections of fields, you can specify the offset and length of the field dynamically.
You can assign one field symbol to another, which allows you to address parts of fields.
Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
You can also force a field symbol to take different technical attributes from those of the field assigned to it.
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. However, since the MOVE statement also supports variable offset and length specifications, you should use it instead. The MOVE statement (with your own auxiliary variables if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.

FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Extras:
1. ... TYPE type
2. ... TYPE REF TO cif
3. ... TYPE REF TO DATA
4. ... TYPE LINE OF type
5. ... LIKE s
6. ... LIKE LINE OF s
7. ... TYPE tabkind
8. ... STRUCTURE s DEFAULT wa
The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Untyped Field Symbols ad Cannot Use Field Symbols as Components of Classes.
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN. All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT> TYPE ANY.
DATA SFLIGHT_WA TYPE SFLIGHT.
ASSIGN SFLIGHT_WA-PLANETYPE TO <PT>.
WRITE <PT>.
Addition 1
... TYPE type
Addition 2
... TYPE REF TO cif
Addition 3
... TYPE REF TO DATA
Addition 4
... TYPE LINE OF type
Addition 5
... LIKE s
Addition 6
... LIKE LINE OF s
Addition 7
... TYPE tabkind
Effect
You can define the type of the field symbol using additions 2 to 7 (just as you can for FORM parameters (compare Defining the Type of Subroutine Parameters). When you use the ASSIGN statement, the system carries out the same type checks as for USING parameters of FORMs.
This addition is not allowed in an ABAP Objects context. See Cannot Use Obsolete Casting for FIELD SYMBOLS.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See Defining Types Using STRUCTURE.
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP Dictionary (s). All fields of the structure can be addressed by name: <fs>-fieldname. The structured field symbol points initially to the work area wa specified after DEFAULT.
The work area wa must be at least as long as the structure s. If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.
