I have tried to deploy an ear application to remote websphere but i am not able to ping the server within plugin configuration dialog.
I have successfully deployed on a local server.
This is what I did in order to configure remote server :

1. Copy DummyClientKeyFile.jks and DummyClientTrustFile.jks from remote server to jenkins server and configured those files within plugin dialog.
2. Import remote server certificates by using InstallCert program mentioned in plugin documentation by using hostname 9043 as parmeter. hostname is
the remote server address and 9043 soap port of admin console
3. copying jssecacerts which contains both certificates from step 2. into JRE/lib/security where JRE is the java runtime environment jenkins is runnging under
4. restart jenkins server

I am not able to ping the server always get a ssl exception :

Any help will be appreciated
