logon page modication preview works but errors when assigned to Authscheme or as appication alias or both

Hello Experts,

Our portal is being upgraded from 7.01 to 7.31 SPS 10, we have a customized logon module and are trying to migrate this application.  As part of migration, we followed below steps -

1. Convert the par to ear using Par conversion Tool

2. Import into Java EE perspective of NWDS 7.31

3. Migrated the project to Java EE

4. Corrected jar class library from 7.31 except com.sap.security.core.imp.TenantFactory, which is not available in 7.01 or 7.31

5. Updated application.xml and application-j2ee-engine.xml as suggested in site with context_root and dependency on om.sap.portal.runtime.login6. Tried to deploy to server, the ear file got deployed

7. Previewed and the application was showing coming well with customizations

8. Logged into nwa/auth and edited ume.logon.application.ui_resources_alias to point to alias defined in the application.xml

9. Result:all logon related screens were coming as blank, logon was not possible from any of the links - irj/portal, nwa etc

10. Tried restarting, modifying authschemes along with editing the ume property. All combinations were tried but no luck.

I have done some investigation on internet, and have seen replies that all the JSP errors need to be resolved to get through the blank logon pages, but I still have 340 erorrs and out of which 320 are JSP erros on variables from <include> text files, more or less NWDS errors. and remaining 20 are related to com.sap.security.core.imp.TenantFactory. There seems to be no scope to clear these errors as these seems to be eclipse compilation realted or getting an library file which is not existing in 7.01 or 7.31.

Any inputs from your side on this situation on in general migration of logon pages to 7.3X would be helpful?
