Logon Page

[Former Member]

Hi,

We have recently migrated from 7.0 to 7.3

And the problem we are facing is we had a customized logon screen in 7.0.

And when we are deploying the same to nwds 7.3,

We are getting this error in logs:

An error occured during authscheme computation.
[EXCEPTION]
com.sap.portal.prt.broker.PortalModuleNotFoundException: Could not retrieve portal application

Where am I going wrong.?

Note 1938160:Portal irj throwing runtime exception after upgrade when using custom logon component

Symptom

• After upgrade to 7.30 or higher, you are unable to access the portal /irj as runtime exception error is thrown
• Other core services such as /nwa and /useradmin work correctly
• You are using a custom logon component

Environment

• Enterprise Portal
• SAP Netweaver 730 and higher

Reproducing the Issue

1. Log into Enterprise Portal /irj application using custom logon component after upgrade to 7.30 or higher
2. Portal runtime exception error thrown
3. Corresponding error is found in the trace file similar to the following:

EP-PIN-PRT#tc~epbc~prtc~core#C000A0473C26013D0000000000000E9C#2693322500

An error occured during authscheme computation.
[EXCEPTION]
com.sap.portal.prt.broker.PortalModuleNotFoundException: Could not
retrieve portal application com.abcdef.logon

Cause

The custom logon component was created based on the NW 7.0X Portal logon component and deployed as a PAR file. This can lead to two problems:
• On NW 7.3 the .PAR files are no longer used and the custom logon application may not have deployed to the system;
• Even if the application was deployed successfully it might not work properly. From NW 7.0X to NW 7.3 there were major changes to the API and since the custom logon application was based on a 7.0 application and uses the 7.0 API, classes and methods available on previous versions might no longer exist on 7.3.

Resolution

Apply the solution described in KBA 1935486 - NetWeaver Portal 7.3X/7.4 and custom logon screens

Hi,

The logon page you are deploying in 7.3 is the same of your portal 7.0?

If it is, you need to download 7.3 version logon page war application, and modify with changes you have maded in 7.0 logon page.

Hope it help
