Sujay, thanks for the extra information.
I can't tell a lot from your dump, because the classloaders just have WEB-INF/classes on their classpath. I'm guessing the problem is that your LoginService is being loaded by the Webapp classloader, and thus it does not have visibility of the server classes like Credential. So I would make sure that all of the classes you use for your login services are on the container class path (ie not in WEB-INF of any webapp). They are server classes and not application classes, so they should not be constrained by the webappclassloader. regards On Thu, 12 Mar 2020 at 21:08, Sujay Pujari <sujay_puj...@persistent.com> wrote: > Hi Greg & other users, > > > > Please accept apologies from me. > > > > Last dump shared “Build_parentLoaderTrue_dumpStderr.txt” was for scenario > 1. i.e output from eclipse environment where set Parent Clasloade helped > to resolve No class def issue. > > > > Somehow I am not able to get DumpStdErr on my production build environment > ( i.e sccenario 2 where NCDFE is still persist).
