Hi,
The new java library does indeed support the ClientLogin method of
authentication - although it is currently deprecated and we do recommend
using OAuth2 if you are building a new application.
The error you are seeing most commonly happens when there is a dependency
missing or if you have the wrong version of a dependency. Which version of
the java library are you using? Are you using maven? Do you have other
dependencies managed by maven?
If not using maven, did you add all the dependency jars to your classpath?
It's possible one of them uses an older version of a dependency our library
is using, which doesn't provide the required class.
