Custom Login Module

Hi everyone,

I've just created and configured a new login module according to the

Sap" target="_blank">http://help.sap.com/saphelp_nw04s/helpdata/en/2b/23e4407211732ae10000000a155106/frameset.htm.">Sap Portal Guide.

In particular I've taken the following steps:

- developed a new java project (jar file)

- developed a new library project (sda file)

- configured the login stack (added a reference to the classloader of the SecurityProvider)

However, when I deploy the library project (sda file) onto the application server and try to logon to the portal I get the error:

java.lang.NoClassDefFoundError: com/sap/security/api/UMException

Any help is greatly appreciated.

Thanks,

Marco
