Custom plugin java code to connect to Sharepoint using Keystore credentials

Hello All,

Does any one have any information on custom plugin java code to connect to share point using Key store credentials

Appreciate any help.

Scenerio

Currently we are having custom plugin where it connects to share point using user authentication key which is on Appian onpremise environment but we migrated to Appian cloud environment.So with Appian cloud we are not able  to connect to onpremise share point giving certificate errors- sun.security.provider.certpath.SunCertPathBuilderException.So it means hanshake is not happening.

So we are planning to update the existing custom plugin to use Keystore credetials instead of userauth key.

I was wandering if any one has done any programming regarding this.

So in nut shell- I am looking for java code that connects to sharepoint using Keystore credentials via Smart service

Cheers
