How to support both RTC 2.0 and RTC 3.0

RTC 2.x and RTC 3.x is a special case, because there was no N-1 compatibility (see http://rsjazz.wordpress.com/2013/07/09/new-version-and-now-experiences-with-sdk-and-plain-java-api-across-tool-versions/  for what that is) in RTC 3.x.

So you would run your Plain Java Client Library programs with a classpath to the 2.x version Plain Java Client Library if you want to talk to 2.x and with a classpath to the 3.x version if you want to talk to 3.x http://rsjazz.wordpress.com/2013/07/12/work-item-command-line-client-to-add-a-comment/ and http://rsjazz.wordpress.com/2013/03/20/understanding-and-using-the-rtc-java-client-api/ show how to call the code.

Unless you are in the unlucky situation where the API is gone in 3.x, this should in general work.

Hello Yun,
Unfortunately RTC SDK is not backward compatible yet. Anyway it should be more stable and do not change so much since version 3.0.

Hi Yun,
