How to fetch plan type id using plain java api?
One answer
As far as I am aware there is no public API for Planning. If there is anything left in the Plain Java Client Libraries or the client SDK it is not supported and maybe not even maintained. The package namespace used to be
com.ibm.team.apt
Here is the bit that I have done https://rsjazz.wordpress.com/2015/06/11/creating-plans-with-the-plain-java-client-api/ even that bit required internal API. As mentioned, the API is not public and the Java API is likely not maintained, since the Eclipse Client no longer provides a planning UI.
I would not venture there. See the disclaimer above if you do and get into trouble.
