Handling sessions (identifying, mapping)

Hi.
I'm still new to handling sessions and users with javax.servlet.*
Two questions, one about identifying one other about mapping :
-how do you access the user login name ? The object HttpSession.getId() tells me nothing interesting, because this id changes everytime the user connects
-in a project where there are information about the user (say a UserAccount class) to be mapped to him, in what piece of code do you code the bind action? I'm using the FORM memory realm, from TOMCAT. Is it possible to bind objects to a user with this kind of authentication?
Thanks!

If you are using FORM based authentication then you can get the userid of the logged user using the following:
1.
String userid = request.getRemoteUser();OR
2.
java.security.Principal user = request.getUserPrincipal();
String userid = user.getName();
Where request is HttpServletRequest

Does SQL Server 2008 R2 recognize only system-generated session identifiers,

As part of the locking down of our system we are doing the Security Technical Implementation Guide (STIG) and one of the questions it asks is "The DBMS must recognize only system-generated session identifiers."
I have looked at the STIG version for SQL Server 2012 and this is not a finding on it, since it supports the requirement and cannot be configured out of compliance.
If anyone can help confirm that this is also the case with SQL Server 2008 R2 that would be very helpful.
Thank you, Darren
The discussion of it is:
This requirement focuses on communications protection at the application session, versus network packet level. The intent of this control is to establish grounds for confidence at each end of a communications session in the ongoing identity of the other
party and in the validity of the information being transmitted.
Unique session IDs are the opposite of sequentially generated session IDs which can be easily guessed by an attacker. Unique session identifiers help to reduce predictability of said identifiers.
Unique session IDs address man-in-the-middle attacks including session hijacking or insertion of false information into a session. If the attacker is unable to identify or guess the session information related to pending application traffic, they will have
more difficulty in hijacking the session or otherwise manipulating valid sessions.
The DBMS must only recognize only system generated session identifiers. If an attacker was able to generate a session with a non-system generated session identifier and have it be recognized by the system, the attacker could potentially gain access to the
system without passing through access controls designed to limit database sessions to authorized users.

Hi Darren,
From your description, do you mean the session_id from DMV sys.dm_exec_sessions? If so, the session_id(s) are all created and handled by SQL Server. When session_id <= 50 , it belongs to a system session, and when session_id > 50, it belongs to a user
session.
Below query could help you generate system sessions in SQL Server 2008 R2. Refer to :

Best way to handle session timeout

Hello All,
oracle 11g, Apex ver 3.1.2
I am bit confused about the sessoin handling mecahnism for the users .
Which is the best way to handle session for the users is it programatically or by DBA admin level.
What are the pros and cons going DBA Level and Programmatica level.
Before hand I got to have some information on hand for justification.
thanks/kumar

Hi,
I've done a great deal of work with mobile accounts in Snow Leopard and I'm now having a "play" with Lion. To be honest you have to sit down and think about why you need mobile accounts.
If your user only uses one computer then your safer having a local account backed up by a network Time Machine, this avoids the many many woes that the Servers FileSyncAgent brings to the table.
If your users are going to be accessing multiple computers on the network and leaving the network then a mobile account is good for providing a uniform user experience and access to files etc. However, your users will have to make a choice as to whether they want their iPhoto libraries on one Local machine (backed up by Time Machine) or whether they want their library to be hosted on the server and not part of the Mobile Home Sync schedule (adding ~/Pictures to the excluded items on the home sync settings).
With the latter, users will be able to access their iPhoto libraries on any computer when they are within the network (as it's accessed from the users server home folder).
With the first option the user would have their iPhoto library on one computer (say the laptop they used the most) but then would not be able to access it from other computers they log on to.
iPhoto libraries are a pain, and I'm working hard to come up with a workaround. If your users moved over to using Apeture then you could include the aperture library as part of the home sync thanks to Deeport (http://deepport.net/archives/os-x-portable-home-directories-and-syncing-flaw-wit h-bundles/)
He does suggest that the same would work with IPhoto libraries - but it doesn't for a number of mysterious reasons regarding how the OS recognizes thie iPhoto bundle (it does so differently compared to Apeture).
Hope this helps...

Handling sessions in Web Services

Hi all,
I am quite new to Web Services. I am facing problems in handling sessions in Web Services.
I am using Apache Axis as SOAP engine. I have different Web Services like AuthenticationService, DataService and ReportService.
The problem is in handling authentication. I need to authenticate only once using AuthenticationService and maintain the
session for rest of the calls to different web services like DataService, ReportService.
Has anyone faced similar situation?
Please help.
Thanks,
Prashanth

a bit unspecific, anyway, here a solution for a plain JAX-RPC implementation
in a JAX-RPC client, use
((javax.xml.rpc.Stub)myProxy)._setProperty(javax.xml.rpc.Stub.SESSION_MAINTAIN_PROPERTY, Boolean.TRUE);
to let the client maintain session state
in JAX-RPC server, implement ServiceLifecycle and call getHttpSession() on the servlet endpoint context

Handling Session in jsp and bean scope

i have problems with handling session in jsp
I want to check on all jsp pages
first thing is session is null
i want to him to be redirected to first page
and he should not be able to go ahead
I tried
if(session ==null)
response.sendRedirect("Login.jsp");
but this does not seem to work
It is very crtical problem can any one answer
this asap
Also i wanted to know that
I have bean which in turn calls static methods of another class which holds all DomainTable(database tables which do not change frequently)
Information .
This is bean is being implemented by me
in seession scope in a jsp
Do u guys think it would be goo idea to change
scop of this bean as Application in jsp
if so what would be advantages for same
I would appericate if i could a quick reply on both
question
as i am time crunch
arsh

You will always get some value of session and your code wont work. At the end of your Login.jsp, you should create a sesssion and store attributes. Check for these attributes in session, rather than checking session==null.

Handle Session Timeout

I am using JDeveloper 11.1.1.6.
I am trying to gracefully handle session time outs in ADF. My application has been experiencing the 'canned' ADF session timeout popup when I am logged into my application and the session has timed out. That same popup is rendered even if I am sitting at my login page but haven't signed in.
I have followed Frank Nimphius's guidance as explained in the following forum to have my application re-direct to the login page after session timeout. That works great thanks to his well detailed document.
ADF Faces : session timeout best practice
The concern I have now is if I am sitting at my login page and my session times out, the application stays at the login page. I now type my credentials and click log in. Because the application thinks my session is timed out, I am taken back to the login page. Ideally I wouldn't think the login page would hold a session. Do you have any guidance on how I can get around this.

Hi,
what about using programmatic login, in which case the login form is part of a public page (see http://www.oracle.com/technetwork/issue-archive/2012/12-jan/o12adf-1364748.html for an example you can download)

Handle Session data with JAX-WS web services

Is it posible to to handle session tracking with JAX-WS web services without implementing my own session logic.
If posible how do we put values in to session and get them back.
And also assuming that sessions are supported is it posible to share the same session between two web services on the same web application.

Hello!
Do you have any solution to your problem now? I also need to maintain a session bean between 2 webservices. If you solved this, can you please tell me how?
Thanks a lot!

Context handling in message mapping for an IDoc to File Scenario

Hi,
Can somebody help me with this issue. I have an Idoc to file scenario. heres my idoc structure. Its a custom Idoc
Header (1..1)
Detail (0..Unbounded)
         DependentDetail (0...Unbounded)              Note: This dependentdetail is a subelement of Detail
Trailer(1...1)
I created my target structrure the same way as the Idoc structure.
My output is a simple text file. I need the output in this format
Header
Detail1
   Dependentdetail1
   DependentDetail2
   DependentDetail3
Detail2
   DependentDetail1
   Dependentdetail2
Detail3
Detail4
Trailer
Since the Detail and Dependent Detail records are unbounded .
But right now i m getting my output like this:
Header
Detail1
Detail2
Detail3
Detail4
Trailer
But the DependentDetail record in not showing up in the output file. I didnot do any context change in my mapping. So do I need to do any context handling??...If so can somebody explain me with this.
Thanks,
Adam
Edited by: hymanroth on Apr 29, 2011 11:11 PM

Thanks Kenneth foryour quick reply,
Yes, I see the payload for Dependent detail in SXMB_MONI. So as you said earlier there's a problem with my content conversion.
my content conversion is as follows:
Header.fieldNames
Header.fieldFixedLengths
Header.endSeparator
Detail.fieldNames
Detail.fieldFixedLengths
Detail.endSeparator
DependentDetail.fieldNames
DependentDetail.fieldFixedLengths
DependentDetail.endSeparator
Trailer.fieldNames
Trailer.fieldFixedLengths
Trailer.endSeparator
So As I told earlier. With the above content conversion. I am not able to get the Dependent detail record in my output file. So If there is a change in my content conversion can u check it and tell me where I went wrong.
Thanks,
Harsh

Exception Handling for Multi Mapping in bpm

Hello,
does anybody know a way of catching an error occured in a multi-mapping used in an integration process.
It seems to me, that when i am using a multi-mapping in an integration process and an error occurs, the message cannot get back to the integration process. In smq2 I can see, that there is the following error:
CX_MERGE_SPLIT
Regards
Günther

The transformation-step is in an block with an exception branch and it is well configured.
When I use a 1 to 1 mapping and an error in the mapping occurs, all is correct. The integration process jumps in to the exception branch and finishes correct. But when use a multi mapping (1 to n; n to 1; n to m) and an error in the mapping occurs, then there is always an error in the bpe inbound queue.
There must be some problem with the split-and-merge program. I think that the split-and-merge program handles the merging of n messages into 1. You can see this when you test a mapping in the integration builder designer. In a multi-mapping there you can see a xml-structure that envelopes the application messages, f. ex.:
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
   <ns0:Message1>
      <myMessage1>data</myMessage1>
   </ns0:Message1>
   <ns0:Message2>
      <myMessage2>data2</myMessage2>
   </ns0:Message2>
</ns0:Messages>

BPM - Exception handling in multiline mapping

Hi,
I have in a BPM a block with processing mode ParForEach containing a transformation and then a send step.
If the transformation (mapping) generates an exception for one of the lines of the multiline variable being processed, no subsequent lines are passed to the send step.
I want the process to execute the mapping for each line and then send messages corresponding to lines without error. How can I do?
Thank you
Simona

Hi Simona,
I also feel that Michal had suggested the correct solution. Not sure why you are saying that the error gets propagated, if you have defined a proper Exception handling for the inner block.
But regarding your design for "ParForEach", I am not sure whether you really need to carry out a transformation step for each Block instance, in which case you can keep the transformation step before the "ParForEach" block.

How to handle session-timeout in producer-consumer(wsrp) environment.

Hi
We are using weblogic portal 9.2 in federated environment (wsrp) .
We have one consumer Ear and some producer Ear .
we want if session is time out ,then user should direct to some default page .
For that we are firing event in Base Exception handler where we caught all exceptions.
that event is listen by consumer side ,(when session time out producer raise event).
event is fired , every thing looks fine but we are not able to redirect page from producer to consumer (which should not be happen )
I think we are doing something wrong .
Any suggestion/ guidance will help us lot
thanks in advance

Hello,
Probably the easiest way for you to get the behaviour you want would be to put a event handler on a .portlet file (on the consumer) that lives on the page you want to activate if the producer session has timed out. For example:
<netuix:handleCustomEvent event="eventNameComingFromProducer" eventLabel="sessionTimeoutPageActivation">
<netuix:activatePage/>
</netuix:handleCustomEvent>
When your producer portlet sends an event "eventNameComingFromProducer" the portlet on the page you want to activate will pick it up and automatically activate the page.

Handling sessions in BDC

Hi all,
         What do we code to create a new session in BDC Call transaction method.
         Let me explain the situation in brief.
    I have an issue where in i need to upload 5000 records. As per requirement i am supposed to upload only 1000 per session. Please let me know how to create new session dynamically and move the processed data to sessions. And also let me know how to handle the errors in those records after processing 500 records.
       I know that Message_format is the FM to know to errors but I need to handle them dynamically.
Guess we need to go by session method to handle errors but how to do that dynamically.
Thanks and Regards
Amit.

Hi Amit,
Suppose all your records are in table infile.
Keep a counter such that when each record in the table is processed, the counter is incremented.
When 1000 records are processed, call the insert bdc function. Reset the function.
Thus dynamically you create 5 sessions if there are five records.
In the following table, I am creating bdc sessions for the transaction FBV1. It has two screens.
1000 for the first screen(header details) and 3000 for all other records(line item details)

How to get a session identifier in Model project

How can I get any web session context identifier in a ViewImpl class?

Tee hee hee deadlock.
Gho - there is no direct way to do so; perhaps you can explain the use case you are trying to achieve (for example, if you need the user name, there might be a quick and easy answer for you). The general answer is that you would pass in the information needed from the view layer (which does have access to the http session). If it's a bind variable you're trying to set, you can use an ExecuteWithParams binding in the view layer.
For more information, please provide your use case, and we'll try to help.

Context handling during message mapping

Hi,
I'm working on a mapping and it almost works. There is just 1 thing to solve. I use the fixvalues funtion with as input a field A in a segment of my Idoc. This function is used to map a field B in another segment. However as this segment has multiple occurences, I have problems with the context handling: the first timle works ok but then it fails (as the filed A is in another segment/context). How could I fix this? I would like to avoid UDF as I don't know much java.
Kind regards,
Ulrich

Hi Ulrich,
<b>Mapping A_source-Fixvalue-B_target</b>
In the above case What are the elements exist in A_Source same thing will be transfered to B_target . If it is not find any value in Fixvalue table then it will pass the default value. So provde the default value.
If there is not element in context then it won't create b_target not at all for that context. So use the Mapwithdefault() nodefunction before passing the value B_target. so in that case it will generate the empty value instead of none.
Warm Regards,
Vijay
