How to use an SSL cert in a Java program

I'm trying to query LDAP over an SSL connection. I was sent a certificate and ran:

keytool -import -trustcacerts -alias www.the-domain.com -file the-cert.der -keystore store.jks

I then pointed my Java program at the cert by adding the following to the run configuration in Intellij:

-Djavax.net.ssl.trustStore=/path/to/store.jks

I get a socket closed exception when I try to connect. Did I miss a step?

Here is the standard out, slightly modified to remove IP info:

javax.naming.ServiceUnavailableException: <ip:port>; socket closed

I found out what my issue was. I didn't set up my environment correctly. 

env.put(Context.SECURITY_PROTOCOL, "ssl");

when using ssl evidently you need to specify the security protocol, which makes sense....
