The list has ruined your formatting. Can you post with a text-only
message?

That doesn't look like a compiler message.

Nor does this. Can you post actual compiler output?

What new class?

Which class requires SSOID to instantiate it? This class has a no-arg
constructor in 7.0.64:

There are no deprecated methods in SingleSignOn.java. If you want to
know what happened to SingleSignOn.java, follow the revision history
which you can see here:
http://svn.apache.org/viewvc/tomcat/tc7.0.x/tags/TOMCAT_7_0_64/java/org/
apache/catalina/authenticator/SingleSignOn.java?view=log

See r1675282.

> 2.       How does the call flow happen of SingleSignOn methods?

Sorry, I can't help there. :/
