SSO to Web Application from Portal

Hi,
    I am working on a scenario where I need to access a Web Application from the Portal.
    I read about the Application Integrator that is provided by the Portal .
    I wanted to know that can I only have SSO to those Web Application that accept the userid and password and as URL parameters using Application Integrator , ie: those applications that have post method cannot be integrated.
   Please help me out with clearing this doubt.
Thnx,
Pravesh Puria.

Hi Abdulbasit ,
    Please give me more details , we have a Lotes Notes Web application hosted on Domino server , another is J2EE based application. I need to achieve SSO to each of these applications from the SAP Portal.
   I followed the below listed steps:
   Created two systems one for each Web application based on the template generated from the application integrator. I entered the user mapping values for both the systems.
   I also created two IViews. When I preview , the logon page of the web application opens but the user credentials are not passed to the application.
   Please help me with the steps to achieve the SSO , from the reply I interpret that Logon ticket method was used to achieve the SSO and user mapping.
    My email id is : [email protected]
    It will be of immense help to me.
Thnx,
Pravesh Puria.

Not able to run web dynpro application from portal.

Hi portal experts,
I want to run my web dynpro application from portal.
So created a seperate iview and a role for the purpose.
Assigned the iview to the role and also mapped a abap user id to the new role created.
But when I click on 'preview' the iview , getting the following dump.
Error when processing your request
What has happened?
The URL http://mnghcmsap:8000/sap/bc/webdynpro/sap/zhr_cp_admin/ was not called due to an error.
Note
The following error text was processed in the system HRM : Die URL enthält keine vollständige Domainangabe (mnghcmsap statt mnghcmsap.<domain>.<ext>).
The error occurred on the application server mnghcmsap_HRM_00 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: CHECK of program CX_FQDN=======================CP
Method: STARTUP_CHECKS of program CL_WDR_CLIENT_ABSTRACT_HTTP===CP
Method: HANDLE_REQUEST of program CL_WDR_CLIENT_ABSTRACT_HTTP===CP

Method: EXECUTE_REQUEST of program CL_HTTP_SERVER================CP
Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME
Module: %_HTTP_START of program SAPMHTTP
What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system HRM in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server mnghcmsap_HRM_00 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 0 in transaction ST11 on the application server mnghcmsap_HRM_00 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.

Please let me know if I am doing the process correctly and also let me know if I am missing somthing.
Thanks,
Aditya.

Are you able to run teh web dynpro application independtly i.e. without creatin an iview.
http://mnghcmsap:8000/sap/bc/webdynpro/sap/zhr_cp_admin/ by using this link.
or there also you are getting the error.
i guess there also you should be gettign the error.
this is some problem with the FQDN settings in the abap system.
in the host name of the web dynpro applciation server one .(dot) is must.
so you might have to change the host name to some thing like mnghcmsap. from mnghcmsap
thanks

Problems while migrating PDK applications from Portal 7.1 to Portal 7.3

Hi All,
I am facing a problem while migrating a PDK application from Portal 7.1 to Portal 7.3.
Since Portal 7.3 doesnt support PAR files any more it provided with a tool to convert the PAR to an EAR file and deploy the resultant EAR to the new portal.
I converted the PAR into EAR and deployed the file but the application is not executing. When I looked into the log files i found the following exception. The application is not able to identify the tag "documentBody". I checked the protalapp.xml and the "SharingReference" is properly maintained in the file but the error message suggests that its not able to fine the reference to the tagLib uri maintained in the portalapp.xml
Now my question is why is it not able to obtain a reference to the taglib? Did any one face similar problem previously. Can you please provide me with any document for migrating / developing PDK application for Portal 7.3

Hi Amit,
Thanks for your reply. I could see some progress after "thoroughly" going through those links. Thanks a lot (gave points too )
Now I am facing another problem. The application did deploy successfully but with a warning. When i checked the warning it says that the deployment was successful but can not be started.
The log file has the following error message.

Any hints from any one?

No context menu within Web Application in Portal

Hello all,
our user runs Web Application via Portal. Normally they can call up the context menu within the web application in order to access the context menu. There they can drill down, swap characteristic, distribute, etc.
For some user we notice that this context menu is not appearing by right mouse click, but the context menu from the internet explorer. That means that these user can not navigate properly within the web application.
When the user executes the Web application via the Bex browser, the context menu appears properly. When I log on in into the portal/bex browser on the users PC, the context menu is also appearing properly.
Is there an user-specific portal setting, which is to maintained?
Any help would be great.
Best regards,
Stefan from Munich/Germany

Hi Stuart,
The easiest way to achieve the desired behavior is to make some changes to your web-j2ee-engine.xml file.
In the login module configuration element edit the security-policy-domain field to u201C/irju201D. This will provide you access to your application from the portal without re-authentication to be required.

Accessing web application from users' PC

Hi there,
My server is up and running, appsets are working nicely and everything works perfectly. But I have an issue when accessing the web application from a user PC on the same domain, and I'm not sure if it's down to me or not.
From the users' PC, with BPC for Excel open, I click on the link for BPC Web, and Internet Explorer opens and attempts to take me to the web app. But if the address contains the server name, it doesn't work. If I manually type the IP address in instead it works.
Why is this? Have I forgotten to do something, or is it a DNS problem, or other local IT issue?
I'm sure I've missed something really silly, but can't figure out what!
Any ideas appreciated!
Thanks a lot,
Jason

Hi Akim,
I think this is actually part of a wider problem - I have been testing this on my local PC (over the clients' VPN) and now it works fine. But I just logged onto the clients PC using Webex and I can't get into ANYTHING! Not the Admin client, not BPC for Office, not the web application - nothing.
I think I need to go there on monday and actually go through this with one of their network guys - I'm not convinced that it's a problem with the server anymore!
Thanks for your help - I will keep you posted!

Can you reload web application from the Weblogic console?

          Good day, eh!
          Can you reload all your jsp/servlet classes of your
          web application from the Weblogic console?
          A one big button labeled 'Reload application' would be very
          good property in Weblogic

Hi,
          I agree it is a much needed feature. Suppose I just change an init
          param of one application in the web.xml, I don't want to take down the
          15 other webapps running on my server just to be able to have that web
          app restart and re-read is configuration. Of course, I could program
          some servlet that allows changing application attributes and to enable
          restarting, but really this a)does not cover all the cases (i.e. addind
          an EBJ reference binding to web.xml) b) should be provided by the app
          server, not programmed by every little programmer again & again.

Debugging the webdynpro abap application from portal.

I developed a WebDynpro application and integrated in portal. I have to catch some portal events.For that i have written some code in my application. I tried to debug the application from portal by using all the available break-point types.but we could not .
Anybody have an idea how to debug a WebDynpro application from portal.
Thanks,
Kumar.

Hi
Few links to check:
External debugging is not working
Re: Debugging Abap webdynpro appln
Re: Unable to Debug WD ABAP application
Dedug is not working in Production Server.
a) Check on number of R/3 sessions opened at a time.
b) Check that user ID configured in portal using System Mapping Under 'Delegate User Administration' is the same user for which you are setting external breakpoint in backend system.

Moving web-application from WebLogic 10.0.0 to 10.3.3 - EJB Exception

Hello all,

Seems that it happened due to updating weblogic version (changes in jee, jms, ejb, jpa versions?). Could you please advice me how to fix this issue?
Thanks, Ilya

I belive there is no problems for this change, because the versions are the same for java at least for OaS, for weblogic you should see documentation. I think you can try deploying you app to new environment if you get any noclassdeffound error or something like it then you could have problems for versions.

Opening the current screen of a application from portal in a new window

Hi,
We are using EP 7.0 with ECC 7. A Iview is created in portal for a ABAP webdynpro application and attached to a role and that role is attached to a user.
When the user invokes the Iview in portal the ABAP webdynpro application is opened, when a button is clicked in this first screen another screen is shown. From the second screen using portal functionality to open the contents of the screen I tried to open the second screen in new window by using the short cut "Open in new window", but this option opens the first screen instead of the current screen.
Is it a standard behaviour or some issue with this.
Is there anyother option to print the ABAP webdynpro application from portal
Regards,
H.K.Hayath Basha.

Hi H.K.Hayath Basha,
Try to put in Button action cod for open in new windows.

Call Web Applications from Xcelsius using LiveOffice connections

Hi,
I have read the HTG: "How To... Call BEx Web Applications from SAP BusinessObjects Dashboards (Xcelsius) and vice versa" here on SDN. Problem is that it is using BW Connection as connection.
Is it be possible to call web applications using Live Office connections?
Br,
Sonni

Hi Sonni,
If you are building dashboard using live office connection and you want to give a drill down to detailed webi or crystal report, you can use Open document interface. In the particular HTG you have mentioned, Open document approach is not possible because dashboard is based on SAP BW. Since you are using live office, i guess you have the source report published in BOE and you can use open document approach here.
If this is not your requirement please mention your exact requirement.
Hope it helps you.

Terminate web application from servlet

It will be very helpful to me if any one found me the solution for the following.
How can i terminate web application from servlet and also i want to close the browser window immediately from servlets?

How can i terminate web application from servletWhat do you mean by this?
also i want to close the browser window immediately
from servlets?The servlet can't close a browser window, but could send back client code that closes it (i.e. JavaScript as part of an HTML page).

Get installation path of web application from class file

Can anybody tell me how I can get the path on disk to the root of my web application from a class file. Im running under Tomcat 5.5 and I have 3 copies of the same webapp under 3 differenet directories:
C:\xxx\dev\yyy
C:\xxx\test\yyy
C:\xxx\prod\yyy
Based on which directory the web-app, I need to do a lookup on a properties file to pull the right jdbc connection to connect to the appropriate database. So it would be similar to using getServletContext().getRealPath("/") from a .jsp file.
Thanks,
Jason

Sorry for not clarifying. I have a properties file with name/value pairs. I know where this properties file is and I can do a lookup in it. In this file, I have jdbc connection names which point to corresponding jdbc resources in my context.xml file.
jdbcDevDatabase=jdbc/tfmDev
jdbcTestDatabase=jdbc/tfmTest
jdbcProdDatabase=jdbc/tfmProd
These connections are for dev, test and prod databases. Now based on where the web-app is installed on disk, i.e-dev dir, test dir, prod dir, I want to retrieve the corresponding connection. The problem is I don't know how to get a handle to the web apps real path on disk without access to the request object or using getServletContext().getRealPath("/") which are not available to me in a class file.
Thanks,
Jason

Is it possible to invoke external REST web service hosted in WebLogic web application from an Adobe LiveCycle Process (ES-4)

Is it possible to invoke an external REST web-service hosted in WebLogic web application from an Adobe LiveCycle Process (ES-4) with parameters as input and manipulating the response depending on the type of parameters it gets back. Then invoking an Adobe Form and prepopulating the Form based on the response parameters? Do you have sample projects that do this invocation. The part highlighted in red is what I need examples.

You can simply use "Execute Script" operation in Workbench and make use of java.net.URL. Below links should help :
