What value is to be set in javax.net.ssl.trustStore?

[Yogesh Gandhi]

I have one file that is provided to me by the customer (i.e. server.cer)

I used a command something like below to create a keystore.ks file

keytool -import -alias bob -file bob.crt -keystore keystore.ks

I add this to

System.setProperty("javax.net.ssl.trustStore", "keystore.ks");

Can someone please confirm if I am doing it right?

And why not should I do

System.setProperty("javax.net.ssl.trustStore", "server.cer");
