Maintain session in Multiple soap calls

Hi Experts,
We have an requirement which runs 2 synchronous calls.
1st synchronous cal is for validating user credentials and
2nd synchronous call (for successful log in) for uploading data in R/3 system.
The main task is to maintain session(ex: time 15 mins) .
1st synchronous call looks like Mobile Application (soap sender)<--->PI<----->(Soap receiver)Active Directory.
2nd synchronous call looks like Mobile Application (Soap sender)<--->PI<----->(Proxy)R/3 system.
can you pls let me know how can I achieve this requirement and
how to maintain session ID, session (is it in PI or in third party) and from where to maintain session.
Thanks in Adv..

I am calling multiple web service apis from my bpel process on the same link. The Web services are written such that I always have to call a "login" api first which creates a context that's maintained throughout the session. Thus subsequent ws calls have to be made in the same session because all the other web service apis require the context to be present.
You can think of this as a stateful SessionBean (sort of).
The question is does bpel support this?

Session between multiple Webservice calls from PI7.0

Hello XI SDNers,
I am unable to overcome my Webservice session problem using SOAP (Axis) adapter. My scenario is as follows:
I am calling a external Webservice deployed in Axis webservice engine from PI7.0, during my first call: I call synchronous "Login" webservice and I became the response "User is Logged in"
during my second synchronous call "GetItem", the webservice returns "The user doesn't have valid session". The two synchronous calls are executed from same scenario one after another!
I lost my session after the "Login". Is there any way in PI 7.0 to maintain the session?
Note: I tried the same scenario using XML SPY SOAP client, it is working!!! it is maintaining the session between multiple webservice calls.
Is there any suggestions to overcome this problem?
Thanks and regards,
Satish.

Hi Satish,
   We are working on the same sort of scenarios, where we have to call more than one webservice in a sequential fashion using the same session id details.
    What we did was we built new xsds adding session details node using the webserive request and response xsds. And we are maintaining a sessions table which contains session id and status fields in PI. So we send webservice request with the session id details. We wrote an UDF to get the session details from PI and set the status field as busy so that no other request uses the same session details.
   Webserive response again contains the sessions details which can be used for the next webservice request.
Finally after all the calls set back the status to Active in PI table.

MAintain session across multiple DB Adapters.

Hi,
I am using a BPEL process which has multiple DB Adapters.
As far as I understand each DB Adapter call from BPEL is a different session.
Is there any way to maintain a same session across multiple DB Adapter calls i.e to make multiple DB calls in the same session?
thanks,
CD

Yes this is supported.
You'll have to take a look at the support for XA (distributed transactions).
See this thread for some good links to other info.

Maintaining Sessions through Multiple Servlets and Contexts

Hi,
I have a webapplication that works like this:
* User connects to a login servlet on HTTPS
* Users information is authenticated on HTTPS
* An object is stored in the session for other servlets to validate the users access
* Authenticated users are forwarded to an HTTP page where the session is used to make sure they were granted access
My problem is this....Since I create the session in an HTTPS context, when I am in the HTTP context, I am unable to access the session and constantly get NULL. Is there any way that I can access the session from an HTTP context?

What you can do is, just login using HTTPS and switch over to HTTP
and then store data in session.That is true, but what I want in the session is basically a flag on whether or not the user was granted access. I would much rather set all that up on the secure line, and then just access it from the unsecure ones...
For example, you are creating session using the
http://testdev:port/index.jsp page.
If access the same page(with hostname)
http://10.300.20.18:8080/index.jsp, you can't get the session even
though both are same web server and same web application. Because the
browser treats it different sessionI think if you use my above solution with the explicit passing of the jsessionid, you can move from one domain to another and still maintain session. Not positive on that though...

Maintaining session across multiple browsers

Hello All,
We have an application that runs using Apache Struts. One of the requirements is to pop-up a "data look up" window, i.e. a new browser window. The problem is, when I start this window any communication between this new window and server happens on a brand new session. I would like to maintain the same session as the parent window. Any ideas?

We use javascript to pass values between a 'data look up' window and the originating Servlet. If this is of any use, I can send you some examples.

Maintaining session across multiple browser windows and page refreshes

Hi there,
We're currently developing a Flex application with a couple of session-related requirements that we're not sure how to solve. Before we jump in and maybe go about things in the wrong way, I thought I'd post and see if anyone here knows of some elegant solutions!
Currently, when our Flex app starts the user is presented with a log-in screen which authenticates the user against our server. Client-server communication is done through BlazeDS.
Our first requirement is the ability to open a new browser window from Actionscript - this window will load a pdf document. The servlet that serves this pdf should deny the request if the user is not already logged in. The only way we can see to do this so far is to open the pdf url using navigateToUrl() with the '_blank' target, passing a jsessionid token as a url parameter. Is there a better way to preserve session state when opening a new window?
The second requirement is to preserve some application and session across browser refreshes. Our Flex app has several screens that the user can tab between. If the user hits F5 or the refresh button in their browser, we'd like the app to return to the same screen after the refresh. I've been looking into using BrowserManager to add a fragment such as #screen=2 to the url, but of course we only want the app to display screen 2 if the user has already authenticated with the server. Is there a way to reuse the user's existing session credentials after a page refresh?
Many thanks in advance for any advice anyone can offer on this. It could very well be that we're missing something about how BlazeDS uses / exposes session credentials that would make all of this easier to implement than we currently realise!

Can we create multiple session in BDC using Call session?

Hi Experts,
Can we create multiple sessions in BDC using Call Session?
Scenario:
Program has to upload 1 million records,so can we programmatically create multiple sessions such that after every 50thousand records we create a different session.
For moment due to large number of records BDC DYNPRO and BDC Field are unable to hold the large number of records,due to which we get a Out of memory error.
Thanks in advance.
Shilpa

Hi
If ITAB is your table with the data to be transfered:
Open the first session:
CALL FUNCTION 'BDC_OPEN_GROUP'.........
IF SY-SUBRC = 0.
FL_OPEN = 'X'.
ENDIF.
LOOP AT ITAB.
IF FL_OPEN = SPACE.
Create new session
CALL FUNCTION 'BDC_OPEN_GROUP'.........
IF SY-SUBRC = 0.
   FL_OPEN = 'X'.
ENDIF.
ENDIF.
Here elaborate your data and fill BDCDATA
Insert the transaction:
CALL FUNCTION 'BDC_INSERT'
IF SY-SUBRC = 0.
COUNT = COUNT + 1.
IF COUNT = COUNT_MAX.
    COUNT = 0.
Close the session
    IF FL_OPEN = 'X'.
      CALL BDC_CLOSE_GROUP
      IF SY-SUBRC = 0.
        FL_OPEN = SPACE.
      ENDIF.
    ENDIF.
ENDIF.
ENDLOOP.

Maintain session when calling servlet from form in a JSP

I have the following set up:
index.jsp calls login servlet from the action tag in a form.
Login servlet handles the login, stores the user info and db connection in the session and uses forward(req,res) to call another jsp.
That jsp has a form where user enters search info and in that form's action tag there is a search servlet. In the search servlet I am unable to access the session.
Is there any way to pass the session to the servlet from that jsp using a form/action?

I've read elsewhere that if you go from a jsp to a servlet that the >request object is cleared of any attributes from the previous request.which is correct. But arent we speaking about session object here? A request object is valid for a request - ie the phase from where the server receieves a hit for a resource upto the point it sends the output for that request.
A session spans multiple requests.
it doesn't retrieve the session info and gives me a null pointer >exception when I try to use the connection object stored in the session.Bad bad bad . Why do you store Connection objects in session? Create them when necessary or use a connection pool. Do you for example clean up the connections when the session expires. What if its a 30 minute session and the user hits every say 15 minutes with a request. Why do you need to hold on to the Connection in the intervening interval when the user's session is inactive?
gives me a null pointer exception when I try to use the connection object stored in the session.which means that the Connection object is null - not the session object.
That last line is where I get the null pointer exception. And that is
Statement stmt = con.createStatement();?
Same answer as above.
If the session object was null,
userSession.getAttribute("connection");would have thrown a NPE.

Run multiple reports through SOAP call,

Hi Folks,
We are able to run a single report at a time through SOAP call , But Is it possible to run multiple reports at a time?
Is there any solution for it or any other way to do it?

Hello,
By default, the reports server is configured with maxEngine=1
It means that ther eis only one engine and only one report can be executed at a given time.
You can increase this value in the file rwserver.conf in order to allow several reports engines to be launched by the reports server and several reports being executed at the same tilme.

How to differentiate multiple aRFC calls into the same session.

Hi experts,
I have following problem:
I start multiple aRFC calls in the same remote session by using the same task ID for each call and use
KEEPING TASK when receiving the results.
The calls are all of the same RFM (e.g get_status of obj), just calling parameters changes ( in the generic example, the parameter: obj).
In the receive method, I differentiate to which obj the result is related by exporting the obj_id on success of the RFM.
My problem is when the status call fails. I just get an error message explaining what the problem is. But I don't get the exporting parameters.
Do you have any idea how to solve this problem?
kind regards,
Sahla

This is actually the workaround I made to go on.
Actually the underlying logic in the RFM for getting the status is based on a synchronous call, as to say when you get the exception you know of which request it comes from.
Therefore the exception messages and their parameters are well defined and according to the error situation filled with necessary data explaining the exception situation.
Unfortunately the excpetion class used is based on the message T100 interface and has the limitations of just four message parameters and each of 50 charcter length.
I overwrite the last message parameter with the needed obj parameter, taking the risk to overwrite valuable system responses explaining the situation.
I thought there could be a more elegant solution from the framework itself.
kind regards,
Sahla

SOAP Call to SAP RFC

Hi,
I have a scenario in which I am calling a RFC from SOAP client. RFC has been exposed as a web service. The RFC takes a table parameter. The Table param is Not Optional.
Everything works fine except when I try to send an invalid value in the Export Param to the RFC. The SOAP Call Fails and I get a fault Message.
If there is an invalid value in the Export Param the Table Parameter is Null. So is that the reason why the SOAP call fails??
Any help regarding this would be appreciate. Tried searching OSS but could not find anything on this.
Here is the Fault Message:

Multiple BAPI calls in RFC Adapter

Hi, Dear Friends!
I have asynchronous scenario File to RFC(BAPI).
File contains raws. For each raw I need to execute BAPI.
With the help of each raw I need to construct one document in R/3 database with the help of BAPI.
But now my scenario provide only one document (only one BAPI is executed).
I read file to xml structure. This structure contains elements. The elements represent raws of file. But BAPI is executed only for the first element.
How to explain to XI that I want it impement BAPI N times - as number of raws in file (or elements in xml structure).
So how to implement multiple BAPI calls. Have you any idea?
Thank you in advance.

Keep alive a session between 2 BAPI calls

Hi -
I am calling several BAPIs to maintain data. I am calling from an outside system as I published the BAPIs as Web Services.
I would like that the session between 2 BAPI calls is kept, so I don't miss some session info between call #1 and call #2.
Anyone knows a way of keeping alive a session between 2 BAPI calls?
Thanks !

Maintaining Transaction Across Multiple JSP Pages

          Hi,
          I have a multi page Registration (3 steps). On each step data submited is taken
          to the database via an EJB component (Session Bean). How do I maintain a transaction
          across these JSP pages so that the data in the database is consistent. If a there
          is a problem in the 3rd step the data submitted in the first two steps should
          be rolled back.
          How do I maintain transaction across multiple pages.
          Regards
          -MohanRaj


It will take from several minutes to a long time for a user to complete a multiple page registration process. Do you really have enough database connections that each concurrent user can hold on to one?
Usually you cannot open more than 50-200 connections to a database at any given time.
Remember that some users will abandon the registration process. Can you afford that their sessions holds a db conenction until the session times out?
Consider changing your datamodel so you can run and commit a transaction at the end of processing the form data from a page. Immediately after the commit give the db connection back to the pool inside the app. server.
It can be as simple as having a column in the database of type enum, with a set of values that shows how far in the registration process the registration has procesed.
BTW. if you absolutely have to hold on to the db connection, you can stuff it into a session scoped attribute and it will be available on all pages.
