NotesException: Session closed due to communications failure

I searched around IBM website and found that the exception is realted to the file TrustedCerts.class. And then I saw this article: http://www-1.ibm.com/support/docview.wss?uid=swg21246028. Just curious, I followed the instruction and put the file TrustedCerts.class into a jar and move the jar file into the path <java_home>/jre/lib/ext/. Wow, it fixed my problem also.

Now, I am getting confused. I don’t understand why the file TruestedCerts.class can not be found in the path /AppServer/classes/? What’s the difference made when I put TrustedCerts.class into the jar and move into <java_home>/jre/lib/ext/? Please help and thank you in advance.
