Adding a button/link in the portal logon page

Hi,
I am new to the portal related things. I am a web dynpro developer and familiar with the Java coding.
Now, i got a requirement to modify the portal logon page as below:
Need to insert one extra button/hyper link to reset the password.
when user clicks on this button, i need to call an RFC in R/3 by passing the entered user name. That RFC will generate a new password and send a mail to the respective email address(maintained in a custom table in R/3 itself).
If the user-id is wrong i need to show the error message returned from the RFC.
If the return-code of RFC is success, then need to show an information message conveying that the password reset was successful and refer to your mail inbox.
Please suggest me the best approach on this scenario.
I already imported the PAR file for logon page and can see the project in NWDS.
Note: we are using EP 7, NW2004s and R/3 is ECC 5.0
Thanks & Regards,
Kiran Chennapai

The Funktion Prem is suggesting can be turned on/off through the UME Properties which can be changed through the Config Tool.

How to redirect the portal Logon page..IMP

Hi Frndz..
I want to know how i can change the Portal default logon page, means when ur giving url on browser like
http://host:port/irj/portal it will directs us to default portal logon page that we r familiar.
As per my requirement when we call the url ( http://host:port/irj/portal) it should call a custom JSP(fancy screen with AJAX&XML) page that i made , from this page i need to access portal .
So i want to use this custom JSP page as my portal logon page .
Thanks in Advance

Error on Portal Logon Page

Hi Experts,
We are getting exception while calling the Portal URL.
Recently, we changed the password policy and made some customizations on the com.sap.portal.runtime.logon.par file.
After that when I tried to access the Logon page, it gave an exception.
I even replaced the customized logon par file with the original one but it did not help.
Please note that I deployed the logon par file with the same name, so I did not have to make any changes in the authschemes.xml file.
So ideally when I replaced the customized PAR file with the original one, it should have worked out.
Can it be because of some UME property "Password Policy change" or something like that which has been changed by our Basis team in the Config tool and which is creating issues now.
Is there any connection between the UME property and the Portal Logon page? I know that UME comes into picture once the user clicks on Login button after entering the login credentials but does it also come in picture at the portal logon page call?
We are not able to trace out the root cause as both Password Policy Change and deployment of PAR was done parallely due to which we are confused about the cause of the issue.
Please find below the trace against the exception ID:

Hi,
Check if your portalapp.xml has an entry "<property name="ClassName" value="com.sapportals.portal.ume.component.logon.SAPMLogonComponent"/>"
If it is there, then I feel that this is an issue with jar files not getting imported properly.
Just try including these two jars (umlogonbase.jar and com.sap.portal.runtime.logon_api.jar) from
usr\sap\J2E\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps\com.sap.portal.runtime.logon\lib
and copy manually to the lib folder under PORTAL-INF in your project.
Regards,
Vijay.

Different portal logon pages with same url.

Hi all,
Im doing portal logon page customization . My requirement is when a user give the portal link in his browser he should get the portal logon page according to the country language..for example if he opens the portal from india he should get English text and if he opens the portal from japan he should get the japanese text in the portal logon page.
thanks
Rajeev B

Rajeev,
Its possible to have the different logon pages for the same portal.
Its also possible for the same ulr but different parameters.
You can do customization on portal logon page.
For example:
Consider that the url http://myep:50000/irj/portal is currently using to access the portal.
You can pass addintional parameter on this url and fetch them into logon page, display the pages based on the values that you have fetched.
for example http://myep:50000/irj/portal/myparam
Have a lot at this link,

To redirect the Enterprise portal logon page

Hi all,
Due to a certain requirement from the client, I need to redirect the logon page, immediately after the user authentication in portal.
At present once the user key in the credentials, it is taken to the portal home page http://...../irj/portal.
Now because of the requirement, instead of the initial home page, i want to redirect user to another page.
e.g http://..../irj/KMdocument/.... . I would be storing the new page location in KM of portal.
Please suggest me a solution to redirect the initial start page in portal.
If you need more details, please let me know.
Thanks
Namit.

Hi chander,
Could you help me to know, where should I change the windows features, like toolbar = 0 etc. as you have mentioned in your message???

User would you the link http://someadd/irj/portal... he would get the normal login screen, where he would enter the username and password.Once he has entered his credentials, he needs to be redirected to another html page or if we can change the initial screen windows features it should be fine.
Please help me on this...
Thanks

Cannot view personalize link in the portal header

I cannot see the personalize link in the portal header of the BI portal. I have already verified the two things below:
1) personalize link is enabled in masthead iview through portal content->portal users->standard portal users->default frame work page-> select masthead-> open its properties->enable *Show Link in Masthead: Personalize *
2) The end user role is assigned under content administration->portal content->content provided by sap->end user content->standard portal users->worksets->portal personalization.
What else can i check, please help. I need this for end users to carry out user mapping. Or any other way they can carry out user mapping ?
thanks

Hi Balajee,
He can see the masthead property Show link in Masthead: Personalize so I doubt you need to make any changes to the PAR file for masthead.
personalize link is enabled in masthead iview through portal content->portal users->standard portal users->default frame work page-> select masthead-> open its properties->enable *Show Link in Masthead: Personalize *

BW bookmark links to the portal.

Hi,
Can we integrate BW bookmark links in Enterprise Portal?
If possible, I would like to know the steps required for integrating BW bookmark links in the Portal?
Thanks

As I mentioned earlier to Ryan. See the link below. KM is only going to give you the Portal Favorites function which enables users to maintain their own bookmarks and personalize the links they wish to have. If you want greater flexibility and group distribution of the bookmarks click on my link below for additional info.

Best way to handle calling the EP logon page

I would like to be able to handle the following:
1. Start EP in anonymous/guest mode (basically unauthenticated).
2. Present an iview that allows a user to fill in some information but when he/she clicks on a button it would first check if the user is logged on and if not -- call up the EP logon page/self registrtion page. After logging in/self-registrating, the iview would continue processing.
What is the best way to handle this?
Regards,

Hi,
You have to download the com.sap.portal.logon standar "par" and modify the jsp file to simplify the logon page (maybe only input fields for user and password).
then upload the new .par file to the portal and update the authschems.xml file to redirect the default method to the new ".par".
You can insert an "enter" button in the home page that launh a pop up to a dummy page with property "default" authentication scheme. Automatically the Portal shows you in the little pop up the simplyfied login page to insert login data. The dummy page need to redirect the parent page to the portallauncher component and close itself.

Accessing KM Document Iview which contain .exe file from Portal logon page.

Dear All,
I was trying to access the KM document ivew(where I uploaded an .exe file in KM and created an ivew for that) in my portal logon page which is customized.
I am calling the ivew through an html command "href".
Now my issue is, while clicking on that link, that exe file is opening with the full portal ivew path name without any extension.
But the actual exe file of same size which is uploaded is getting downloaded and saved with out any extension. I always have to change the name and give .exe extension for that to open properly.
So, can some one suggest me how to open the actual exe file with the extension?
Cheers,
Anu.

Sorry Tom!
Your problem seems to be different, I've no idea.
But we already fixed our problem, I forgot to post. Here's our solution:
The solution was to create a KM Docs iView with anonymous authentication schema pointing to the download file. Then we created an URL iView pointing to this KM Doc with appending the filename AGAIN to the URL (because otherwise the iView ID will appear as filename). In the page a hyperlink now is pointing to the URL iView and after clicking it, the download starts with the correct filename.

Portal Logon page repeating/ redirecting to itself on first attempt

All,
Apologies in advance if this is not the appropriate forum. We are in the process of migrating a NW7.0SPS13/EP7.0SPS13 installation from a remote site to a local site with a database only UME and SSO to an ECC6.0 backend. The new target installation has picked up a rather odd behavior. When loggin onto the portal, the logon page repeats/refreshes/redirects to itself with valid ID and password with no error message. The only apparent action is the clearing of the password field.
My only clue so far is the absence of this script in the http trace on the initial logon attempt which shows up on the second attempt:
http://<host>:51100/irj/portalapps/com.sap.portal.httpconnectivity.httpauthentication/scripts/CAManagerScript.js
I did find this related thread and attempted the suggestions with no luck:
Re: portal logon page coming again
I felt this might be the best place to post question since this may be an authentication/connectivity issue.
Thanks in advance,
Lee

You are correct, we are not implementing SPNego but at this point I will take any suggestions that might be conceptually related...
We are attempting to migrate/clone the entire server (OS,J2EE,MSSQL05...) from a remote hosted environment to a local network environment.
I checked the Everyone, Authenticated, and Anonymous groups for the correct roles/Java permissions and all seems to be in-line with the correctly functioning remote system with correct user assignment.
With some further log filtering I was able to where find this error:
The default keystore view [TicketKeystore] does not exist. Authentication stack: [ticket]. The possible reasons for that problem are: keystore does not exist or the user has no permission to read from the keystore view. You can delete the TicketKeystore and restart the engine so that the engine automatically re-creates it.
I suspect the SAPLogonTicketKeystore was recreated incorrectly... I will have the migration team recreate it again. FWIW, I am unfamiliar with the process of assigning user access to this object as the error suggests.
Thanks for the suggestions...

Error deploying new portal logon page

Hi Gurus,
I'm getting an error deploying my new portal logon page. I've made teh necessary changes to the portal.logon.par.bak file. I've rename it and made the necessary changes in config tool. i've created a new autoscheme_test.xml file and have assigned it accordingly. After restarting the portal, i'm getting the error message below trying to launch the portal :-
Portal Runtime Error
An exception occurred while processing a request for :
iView : N/A
Component Name : N/A
The exception was logged. Inform your system administrator..
See the details for the exception ID in the log file
Any ideas? Are there any other setting that i need to do aside from teh autosceme file. thanks

Hi Johan,
There are two lib files which you need to paste while you import the file in the NWDS.Just check for the steps through this weblog
the jar files name are
com.sap.portal.runtime.logon_api.par
umelogonbase.jar
(when you unzip you can find the files at PORTAL-INFlib)
