NoClassDefFoundError in custom login module



I'm developing custom login module on EP6.0 SP2 (deployed as jar file). I'm using some classes in and

I set all path to all jars in my IDE (NetWeaver DS) correctly. But when I'm trying to login to portal, an exception (NoClassDefFoundError: ~some class from jars above~) raised.

Jars I was writing about above, are located on portal in .../cluster/server/additional-lib.

In library.txt are entries:

library com\sap\security\api\;com\sap\security\api\;


library MyLoginModule MyLoginModule.jar

reference MyLoginModule

Even when I copied mentioned jar files from portal to my project folder of my login module (and therefore to my jar file), i got the same exception.

Can anybody help me?
