Please Explain Struts Module

Hai all
i have a big doubt in Struts
what is meant by Modules ??!!!
i have a webapp mystruts where the dir structure is like
\mystruts
images
pages
tiles
WEB-INF
classes
lib
struts-config.xml
say i want admin module . what it means am i creating any extra folder strutct to do so or am just creating just another struts config xml file ?? liek
\mystruts
images
adminpages
admintiles
pages
tiles
WEB-INF
classes
lib
struts-config.xml
struts-config-admin.xml
is this ok ??? am i right
please help me its urgetn

Probably, like me, most of us never used that aspect of struts. I wasn't aware of it, actually, and would presume if this is a real thing, then there should be something in the Struts documentation... so what's that say?

Please explain the MODULE in ABAP programming

Hello SAP gurus,
Kindly explain MODULES in programming...
Thank you very much!

hi there....
before i go ahead, i take this as u know report programming. so chk this link to find differences between the two
http://www.geekinterview.com/question_details/18029
mostly, dialog programming helps the user to forget about the layout as it does this automatically for us. we need to concentrate on the logic. it sometimes gives a feel of visual basics. moreover, it can write on the database other than fetching data from it as in report programming.
do reward if helpful or get back with further queries.

Could you please explain about the chain and end chain and module

hi experts
could you please explain about the chain and end chain and module keywords?

Hi Naresh,
Conditions for Multiple Screen Fields
To ensure that one or more PAI modules are only called when several screen fields meet a particular condition, you must combine the calls in the flow logic to form a processing chain. You define processing chains as follows:
CHAIN.
ENDCHAIN.
All flow logic statements between CHAIN and ENDCHAIN belong to a processing chain. The fields in the various FIELD statements are combined, and can be used in shared conditions.
CHAIN.
FIELD: <f1>, <f 2>,...
MODULE <mod1> ON CHAIN-INPUT|CHAIN-REQUEST.
FIELD: <g1>, <g 2>,...
MODULE <mod2> ON CHAIN-INPUT|CHAIN-REQUEST.
ENDCHAIN.
The additions ON CHAIN-INPUT and ON CHAIN-REQUEST work like the additions ON INPUT and ON REQUEST that you use for individual fields. The exception is that the module is called whenever at least one of the fields listed in a preceding FIELD statement within the chain meets the condition. So <mod1> is called when one of the fields <fi> meets the condition. <mod2> is called when one of the fields <f i> or <g i> meets the condition.
Within a processing chain, you can combine individual FIELD statements with a MODULE statement to set a condition for a single field within the chain:
CHAIN.
FIELD: <f1>, <f 2>,...
FIELD <f> MODULE <mod1> ON INPUT|REQUEST|*-INPUT
|CHAIN-INPUT|CHAIN-REQUEST.
MODULE <mod2> ON CHAIN-INPUT|CHAIN-REQUEST.
ENDCHAIN.
The module <mod1> is called when screen field <f> meets the specified condition for individual fields. <mod2> is called when one of the fields <fi> or <f> meets the condition. If you use the addition ON CHAIN-INPUT or ON CHAIN-REQUEST with FIELD <f>, the condition also applies to the entire chain and module <mod1> and <mod2> are both called.
In cases where you apply conditions to various combinations of screen fields, it is worth setting up a separate processing chain for each combination and calling different modules from within it.
The functions of the FIELD statement for controlling data transport also apply when you use processing chains. Within a processing chain, screen fields are not transported until the FIELD statement. Processing chains also have another function for the FIELDS statements that they contain. This is described in the section on validity checks.
Ex:
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
CHAIN.
FIELD: INPUT1, INPUT2.
MODULE MODULE_1 ON CHAIN-INPUT.
FIELD INPUT3 MODULE MODULE_* ON *-INPUT.
MODULE MODULE_2 ON CHAIN-REQUEST.
ENDCHAIN.
FIELD INPUT1 MODULE C1 AT CURSOR-SELECTION.
CHAIN.
FIELD: INPUT2, INPUT3.
MODULE C2 AT CURSOR-SELECTION.
ENDCHAIN.
MODULE CURSOR AT CURSOR-SELECTION.

Hi any one please explain background job scheduling

Hi any one please explain background job scheduling . Good answer can be rewarded.
Thanks

Background jobs are pgms that are scheduled to be run in the Background without user interaction. So this can be done only for Type 1(executable) Program and not for Module-Pool Programs. Typically, a variant is defined and the pgm is run using the same.
The transaction code is sm36 -Define Background job. Using the Start Condition tab you can define when you want the job to run (specific time or if it has to follow after a particular job is done etc.,) Using the Step tab you can assign the pgm name and variant.
After the job is scheduled, you can check the status in sm37, along with the Job log and Spool.

EMET 5.1 crashes Outlook.exe, Photoshop.exe and Communicator.exe. Please explain why it would do that?

Hi,
EMET 5.1 is crashing/not opening these applications on two of our staff workstations (Both are Windows 7 x86): Outlook.exe, Photoshop.exe and Communicator.exe.
One computer, EMET crashes Communicator and Outlook. The other Computer, the EMET crashes Photoshop only.
Obviously, it works for everybody else. Can someone please explain to me why would EMET crash these apps if it works for the rest? Could it be that it found a possible threat/exploit to the machine?
How do I mitigate this problem?
Please advise. Below is a sample of the error.

One guess is that old Outlook plugins can sometimes cause issues with EMET. Try starting Outlook in safe mode, by holding down the CTRL key when starting Outlook to see if that helps, and look in Outlook in File / Options / Add-Ins menu item to see
the add-ons that are installed. Verify that the OS and apps have all the latest patches if you haven't, though you have probably already done that. If those don't work you could try unchecking the EMET application protection boxes for the
application that isn't working, one by one. Note that EMET 5.2 is out now so that might be something to try too.

No ActionResult returned for action [/strutsModule/login] in Struts module

Hi these are the steps followed by me in developing a struts portlet. 
1) I created an Application 
2)Created a new Portal project in the application. 
3)I created a struts project and i placed all my jsps in the folder strutsModule. 
4)In the WEB-INF src folder i placed my actoinClasses and actionForms.(package struture followed like com.portal). 
5)Renamed struts-config.xml to struts-auto-config-strutsModule.xml. 
6)Created a portlet and Portla Pages. 
7)Build an ear and run. 
Directory struture is as follows.
 strutsInter(Applicaton name) 
data 
strutsInter(Project name) 
campaigns 
framework 
resources 
strutsModule(all jsps kept inthis directory) 
visitorTools 
WEB-INF(.pageflow-struts-generated

Security Roles 
Still following these steps i get an No ActionResult returned for action [strutsModule/login] in Struts module [strutsModule]. 
 Any corrections else any basic struture i must follow to avoid these errors.Plz give me the directory struture i must follow. 
Thankx,

Can you please explain about the vehicle management system?

Hi ,
i want to know about the module (vehicle management system) .please explain any one in details .
Regards
Venkata .

Hi Venkata,
The Vehicle Management system (VMS) is part of SAP IS - Auto. Generally it is said that it is used by importers, however I would rather put it like this – It can be used for an importer or a distributor’s business functions. So if an OEM is also performing a distributor’s business, he can also use VMS and get benefited out of it.
The VMS facilitates to see a Vehicle like a Vehicle in the system.
Following are the few high level features -
It allows to capture all the attributes of a particular vehicle as an unique object in the system
All the transaction on a vehicle (sales, purchase etc.) can be carried out keeping vehicle as a central object, provides ease of operation to users. All business and technical data of the vehicle is available here.
Strong configuration based vehicle search and vehicle history (transactions) helps in tracking the vehicle easily for any purpose in the distribution chain of OEMà Distributorà Dealerà End Customer.
This is in brief about VMS.

Please Explain me AcrionForm Flow

ActionForm Flow in struts .
 <form-beans>
 <form-bean name="actionform1" type="ActionForm1" />
 </form-beans>
 <action-mappings>
 <action name="actionform1" path="/one"
 type="ActionClass1" input="/input.jsp"
 scope="request" validate="true" >
 <forward name="fone" path="/display.jsp" />
 </action>
 </action-mappings>
setp 1: when you try to call input.jsp. It will call reset method of the ActionForm1 method
step 2: when click the sumbit method it will validate method of the ActionForm1.
step 3: if Step 2 Validate Method returns actionErrors then is will go to input.jsp once again showing the errors.
else ActionServlet "ActionClass1" will be called.
please explain me if it is wrong.
Thanks& regrads
rathna

setp 1: when you try to call input.jsp. It will call reset method of the ActionForm1 method
step 2: when click the sumbit method it will first calling reset method after that validate method is calling.
Please explain me how it will navigate

Enqueue and Dequeue consept----Please explain urgent

hi all,
i want to use sap locking mechanisn (Enqueue and dequeue consept) while updating database table....please explain how to use this while updating a database table.
Thanks in advance
Nandha kumar

Nandha,
Good document on this concept..
Activating a lock object in the ABAP Dictionary automatically creates function modules for setting (ENQUEUE_<lock object name>) and releasing (DEQUEUE_<lock object name>) locks.
The generated function modules are automatically assigned to function groups. You should not change these function modules and their assignment to function groups since the function modules are generated again each time the lock object is activated.
Never transport the function groups, which contain the automatically generated function modules. The generated function modules of a lock object could reside in a different function group in the target system. Always transport the lock objects. When a lock object is activated in the target system, the function modules are generated again and correctly assigned to function groups.
Parameters of the Function Modules
Field Names of the Lock Object
The keys to be locked must be passed here.
A further parameter X_<field> that defines the lock behavior when the initial value is passed exists for every lock field <field>. If the initial value is assigned to <field> and X_<field>, then a generic lock is initialized with respect to <field>. If <field> is assigned the initial value and X_<field> is defined as X, the lock is set with exactly the initial value of <field>.
Parameters for Passing Locks to the Update Program
A lock is generally removed at the end of the transaction or when the corresponding DEQUEUE function module is called. However, this is not the case if the transaction has called update routines. In this case a parameter must check that the lock has been removed.
Parameter _SCOPE controls how the lock or lock release is passed to the update program (see The Owner Concept for Locks). You have the following options:
_SCOPE = 1: Locks and lock releases are not passed to the update program. The lock is removed when the transaction is ended.
_SCOPE = 2: The lock or lock release is passed to the update program. The update program is responsible for removing the lock. The interactive program with which the lock was requested no longer has an influence on the lock behavior. This is the standard setting for the ENQUEUE function module.
_SCOPE = 3: The lock or lock release is also passed to the update program. The lock must be removed in both the interactive program and in the update program. This is the standard setting for the DEQUEUE function module.
Parameters for Lock Mode
A parameter MODE_<TAB> exists for each base table TAB of the lock object. The lock mode for this base table can be set dynamically with this parameter. Valid values for this parameter are S (shared), E (exclusive) and X (exclusive but not cumulative).
The lock mode specified when the lock object for the table is created is the default value for this parameter. This default value can however be overridden as required when the function module is called.
If a lock set with a lock mode is to be removed by calling the DEQUEUE function module, this call must have the same value for the parameter MODE_<TAB>.
Controlling Lock Transmission
Parameter _COLLECT controls whether the lock request or lock release should be performed directly or whether it should first be written to the local lock container. This parameter can have the following values:
Initial value: The lock request or lock release is sent directly to the lock server.
X : The lock request or lock release is placed in the local lock container. The lock requests and lock releases collected in this lock container can then be sent to the lock server at a later time as a group by calling the function module FLUSH_ENQUEUE.
Behavior for Lock Conflicts (ENQUEUE only)
The ENQUEUE function module also has the parameter _WAIT. This parameter determines the lock behavior when there is a lock conflict.
You have the following options:
Initial value: If a lock attempt fails because there is a competing lock, the exception FOREIGN_LOCK is triggered.
X : If a lock attempt fails because there is a competing lock, the lock attempt is repeated after waiting for a certain time. The exception FOREIGN_LOCK is triggered only if a certain time limit has elapsed since the first lock attempt. The waiting time and the time limit are defined by profile parameters.
Controlling Deletion of the Lock Entry (DEQUEUE only)
The DEQUEUE function module also has the parameter _SYNCHRON.
If X is passed, the DEQUEUE function waits until the entry has been removed from the lock table. Otherwise it is deleted asynchronously, that is, if the lock table of the system is read directly after the lock is removed, the entry in the lock table may still exist.
Exceptions of the ENQUEUE Function Module
FOREIGN_LOCK: A competing lock already exists. You can find out the name of the user holding the lock by looking at system variable SY-MSGV1.
SYSTEM_FAILURE: This exception is triggered when the lock server reports that a problem occurred while setting the lock. In this case, the lock could not be set.
If the exceptions are not processed by the calling program itself, appropriate messages are issued for all exceptions.
Reference Fields for RFC-Enabled Lock Objects
The type of an RFC-enabled function module must be completely defined. The parameters of the generated function module therefore have the following reference fields for RFC-enabled lock objects:
Parameters
Reference fields
X_<field name>
DDENQ_LIKE-XPARFLAG
_WAIT
DDENQ_LIKE-WAITFLAG
_SCOPE
DDENQ_LIKE-SCOPE
_SYNCHRON
DDENQ_LIKE-SYNCHRON

Can any please explain the integration business process between PS and CS

Dear Guru's
Can any please explain the integration business process between Project systems (PS) and customer service (CS).
Business Process: We do machinery Erection or commissioning, later we do provide service warranty for one year.
How we map this Business scenario in sap.
Regards,
Bhanu

basic steps for such a process would be
1) Use PS functionality for your machinery erection or commisioning work. Once the physical work is completed then close porject
2) Use CS functionality for warranty and service - set up the work as a functional location on customer site (PM/CS functionality)
3) Use service order to manage any service calls on the object which could require billing via SD module - bill value may be zero if under warranty

Please explain me how I can use Form feed(\f) and Carriage return(\r)

what is Form feed(\f) and Carriage return(\r)?
Please explain to me.
Thank you.

These control characters aren't used much these days except that if you example a Windows or MSDOS text file in a binary editor you'll find each line ends with "\r\n". However when reading or writing text through classes these carriage returns will be added and removed automatically so your program doesn't see them.
The controlls date back to teletype machines which operated rather like typewriters. Cariage return, as it's name implied, caused the print head to move back to the start of the line, line feed advanced a line (without, necessarilly, returning the carriage) and formfeed skipped to the next page.
Newline on these machines was always "return, linefeed" because executing the carriage return on these machine could take too long. The early machines had only a single character buffer so that they had to executed the characters as quickly as they arrived. So doing the linefeed after the carriage return gave the carriage more time to return. On some teletypes if you did "linefeed, return" then the first character of the new line would often be printed somewhere in the middle of the line.
This is the origin of the MSDOS/Windows end of line sequence.
Many printers will still respect formfeed if printing is direct. Some will take carriage return without linefeed to allow you to start again overprinting the same line.
However printing, these days, is seldom direct but done in bitmap form.

Please explain me, how to remove an usb stick or memory chip? With experiences only in pc:s, I do not find on my first apple e.g. MacBook Air a solution. Until now I have succeeded to destroy one chip full of photos and - there's no life more in the port.

Please explain me, how to remove an usb stick or memory chip? With experiences only in pc:s, I do not find on my first apple e.g. MacBook Air a solution. Until now I have succeeded to destroy one chip full of photos and - there's no life more in the port...
Someone told me just to remove the chip in clicking it to the trash can and voilá - it would be done. But as I did so, on the screen appeared a text which let me know, that that way had been the wrong one...
I should have clicked Finder plus something.... which I do not now remember but which was then not found behind the Finder.
So please would someone be so kind and tell me, where I can find explanations for the most simple functions. The manual I got does not include a clue.
Thank you!

First make sure that no application is using or has open any files on the disk. Then:
Click and drag the disk icon on the desktop to the trash. Wait for the system to recognize the action, and the icon should disappear from the desktop. It is then safe to remove the device.
Alternatively, you can secondary click on the disk icon, and then primary click "Eject (name of disk)". Wait for the icon to disappear off the desktop, and then it is safe to remove the drive.
Here is a detailed help document on the subject.
