Creation of servlet object

if there are 100 requests to the server at atime for a servlet, then how many servlet objects are created at that time?

Usually one. But if you care about the number of servlet objects you are probably doing something wrong.

Life time of a servlet object

How and where can i specify that if a particular servlet is idle for, say x minutes, make it eligible to be garbage collected ?

See Servlet Specification 2.4.
So it is there in the spec also.Indeed, the specification says that the servlet container may or may not allow servlet objects to be garbage collected at any time. That passage of the specification does not require that the behaviour should be configurable. Which is what I meant with:
I don't think the servlet spec requires such a
configuration option. Some servlet containers
might implement it; which one do you use?
One more thing. How did you come to know that your
servlet object consumes less memory than your String object ?I have a little program that does:
- start = get free memory
- for (0 ... 100) new WhateverObject();
- end = get free memory
- print (end - start) / 100
That's not 100% reliable. To verify the result (HttpServlet is 8 bytes), I cheated a bit: I looked at Tomcat's source code. The 8 bytes doesn't include everything; e.g. the servlet's configuration data is loaded into a separate data structure, and the servlet contains only the pointer to the config data. But still, even for a few hundred servlets, we aren't talking about megabytes, but maybe about a few dozen kB. The code that would be needed to manage servlet unloading, re-creation and re-configuration would likely be bigger than the size of your servlets...

Creation of login object failed

Hi all,
I've got a problem with the mobile client development.
We are using the mobile client for many years and we even develop a lot with it, but now i have a problem never seen.
After extending a bDoc and start testing the application, after the generation and login, system states "Creation of login object failed".
So i did a full generation. Result the same.
I debugged the ValidateLogin class and found out, that in the following statement is failing
       BOLOGIN = BusinessRootObject.BusinessFactory.LoadBusinessObject("LOGIN", determineUser)
BOLOGIN is Nothing at the end. I tried out to create the Object via        BOLOGIN = BusinessRootObject.BusinessFactory.CreateBusinessObject("LOGIN")
same result. Next i tried to create the BOACTIVITY and it failed as well. One day before everything was fine, even with changing business documents.
The error in the VB.ERR object says:
-     err     {Microsoft.VisualBasic.ErrObject}     Microsoft.VisualBasic.ErrObject
     Description     "In der Methode BusinessFactoryCore.LoadBusinessObject ist eine System-Exception aufgetreten"     String
     Erl     0     Integer
     HelpContext     0     Integer
     HelpFile     ""     String
     LastDllError     3     Integer
     Number     5     Integer
     Source     "MTBLLFW"     String
Can anybody please give a hint.
We are using CRM 5.0 SP7 and MSA SP7 on MS 2003 Server with local repository. DB is SQL2000.
Yesterday i was releasing a changelist and now its no longer working at all, what a mess.
Thanks to all,
Andreas Rose

Hi Andreas,
The problem may be incorrect or corrupt ARSREP.DAT file.
The reason may be that the BDOCs are not synched from MAS. Once you sync this through MAS you will find the *.bdoc files at the location
mentioned under the registry key HKLM\SOFTWARE\SAP\MSA\MW\TL\BDocPath
Usually this would be default as C:\Program Files\SAP\Mobile\tpsfiles.
After this when you generate the BusinessLibrary the Arsrep.dat file
will have the *.bdocs incorporated in the Arsrep.dat file.
Hope this helps.
Regards, Gervase
ps. For synching the BDocs refer to SAP Note 942942

Getting ORA-20001: Creation of new object is not allowed: !!

Hi Am getting ORA-20001: Creation of new object is not allowed while enabling constraints after importing the dumps from source to target datbase,can anyone assist me to fix this issue.

Hi Osama/Mustafa,Thanks for your quick response,can you please explain me the following things-
1)As i don't have privilege to run the DBA_XX views,am not able to run those queries-
SELECT OWNER, TRIGGER_NAME, TRIGGER_BODY FROM DBA_TRIGGERS WHERE TRIGGER_TYPE IN ('AFTER EVENT', 'BEFORE EVETN') AND TRIGGERING_EVENT LIKE '%CREATE%';
can you tell me what output it'll throw,based on this output how will we fix the issue.
2)SELECT * FROM dba_sys_privs WHERE privilege = 'UNLIMITED TABLESPACE';
why we need to check this privilege?as i don't have privilege to run this one in my db.
3)select * from dba_source where upper(text) like upper('%Creation of new object is not allowed%');
as i don't have privilege to run this one in my db,already i got the object name from my logfile
and more you have quoted"This is an error of someone that coded purposely on your database, probably dba or a developer who has privilege and again it is in a database event trigger"
4)can you explain me much more deeper about the root cause and as already sent note to my DBA,can you explain me the solution to fix this issue ?

Creation of new object link for DMS

i have searched a lot about Creation of new object link for DMS on internet .
and all replies focus on that documentation :
1. Program two screens for the following module pools for the SAP object that is to be linked additionally:
u2013 SAPLCV00
u2013 SAPLCVIN
The process logic must be according to that of screen 0204 in program SAPLCV00 and must not be changed.
2. Create the function module OBJECT_CHECK_XXXX (XXXX = name of the SAP object).
i need to know how to implement that in more detailed step by step
as i know DMS and abap also.

Hi Reda,
Hope the below URL will help to understand how the Process of adding a object link works.

Error while Debugging MSA 'Creation of Login Object Failed'

Dear Friends,
I am working on CRM Mobile Sales 5.0 SP 5.
I have setup my Mobile Client and Mobile Application Studion On the same machine.
I have perform the initial generation of the application from Mobile Repository server to my machine.
it gave me 6 errors and 12 warnings and took about 4 hrs for generation.
Now when i tried to debug the generated application,
i get my login screen and once I enter username and password.
Error popups up stating "Creation of login object failed".
and then another error
"Starting MPPFailed" (MPP is my project name).
Please suggest me how should i go about to debug the application solving the above errors.
Awaiting Reply,
Best Regards,
Pratik Patel

Am not sure if you were able to resolve the issue but below are some points:
a. I think the dlls sfabol and msa are not any more registerable, since they are more of VB.NET components and here assembly is registered and not the dll.
b. For logging into the application just ensure that you have user id in table SMOUSER and the employee for that user in SMOMITABT table.
c. If this is fine, then ensure that you have the latest BDOC metadata information on your laptop. I think in 5.0 also you need to use Clientconsole to download this information.
d. If this is all okay, then try running SQL profiler and check if the query to the ides db is being executed by the framework. If the query is fired then it means application seems to behave properly but the query is not retrieving relevant details.
For further details feel free to contact me..
thanks,

"Creation of login object failed" after MAS generation

Hi everybody,
I am working on CRM Mobile Sales 5.0 SP6. I have performed the initial generation with the .NET Application Studio. It gave me 6 errors and some warnings. Now when I tried to logon my mobile client I 've got following error:
"Creation of login object failed".
Visual Studio is installed on partition "C:\Program Files\" and Mobile Sales on "D:\SAP\"
Has someone any ideas? Thanks in advance,
Mirko

Hi Mirko!
In your app you're calling unknown data structures. While generating the "compiler" read the names and want to create the relevant structures but the necessary data to do this are missing. You have to start fist the client console doing a complete meta data generation. If this runs without error your generation inside the studio will succeed, too.
BTW: In your first posting you've written "D:SAP..." and in your last the error-message was "D:ProgrammeSAP..."...
Perhaps different settings?
Do you have made already a successful generation with the actual installation?
Good luck,
Ingo

" Automatic creation of Cost object owners"

Hello Experts,
I am working on a rollout project, for "Inter Company Service Invoicing (ICSI)"
Presently my client requirement is " Automatic creation of Cost object owners"
First of all i will explain the process
In ICSI there are two parties one is Service Requestor(SREQ) and other one is Service Provider(SPROV)
Depending on SREQ requirement SPROV will create a SO and send it to SPROV
It will reach SREQ contact person, he will updates Cost objects, and send it to SREQ reviewer person, he will check the cost objects and send it to Cost object owner of the SREQ.
He will approve the SO, once all approvals hasbeen done, then system automatically converts SO to IV, and post entries on both sides automatically ata the same time.
Here my requirement is on SREQ side the Cost Object Owner should find automatically.
And we done this proces in Portal itself.
Your suggestions will be great help to me, and are appreciated.
Thanks in advance
Any inputs please...............
Regards,
Satya.

Hello Ajay,
Thank you for the response.
But my requirement is not to populate cost objest.
It is the approval flow. The reviewer person will check and add the cost objects to the service order and send that Service Order for the final approval i.e.. Cost Object Owner.
So here my requirement is the System has to create that Cost Object Owners Automaticlly
How can i achieve this?

Satya

Regarding Servlet Objects...

Hello Everbody,
Can anybody tell me how to keep alive Servlet object forever, i mean until Tomcat server is shutdown?
Thanks in Advance
Srinvas PV.

The reason is: Servlet will do some tasks which
are scheduled on some time and need to run after
some specified time duration continuously forever
until the server shuts down. The servlet will start
some other class object to do the task. So to work
properly of the class object, the servlet will also
need to be alive.
Then there is nothing to be worry about. A servlet is meant to be running continuously until server shutdown, or as long as the servlet container does not need to free memory.
You may need to take some precautions though.

Problem in creation of Accrual Object

Hello Gurus...
Am unable to do the recording for transaction ACACTREE01.
Basically, we have a tabstrip and these tab are getting recorded but in each tab we need to add a record and in that record, data should be given.
Say, in this tcode, we can see tabs like Item data, Parameters and Account Assigmnet. In Item data tab, we need to click on Create button to create a record and once this record is created then only we need to give the data in that record. The same applies to other 2 tabs also.
Main problem is recording is unable to capture the creation of record and the data which is inputed.
So, could you let me know how to do this recording or is there any alternative method for it.

Hi,
I think you should check if the authorty object that you are using has been created you can try to use transaction su21, i think the authority object that you are trying to use does not exist.
Check the below link for more info
