How to support both RTC 2.0 and RTC 3.0


Yun Li (1154) | asked Jan 05 '12, 1:11 a.m.
I write a program to retrieve workitems from RTC, but I need to support both RTC2.0 and RTC3.0, if I use RTCSDK2, it can not connect to RTC3.0 system. If I use RTCSDK3, it can no connect to RTC2.x system.

Is there any method to support both of them?

Thanks a lot!

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.

Best regards,
