Java sdk : org.ovirt.engine.sdk4.Error: No connection implementation found

Hi,

I was trying to use java sdk version 4 and followed the guide from ovirt-engine/docs/manual/en_US/html/Java_SDK_Guide/index.html.

When I tried to run my java application, I got the below stacktrace:
Exception in thread "main" org.ovirt.engine.sdk4.Error: No connection implementation found
at org.ovirt.engine.sdk4.ConnectionBuilder.connection(ConnectionBuilder.java:77)

Where the Test.java at line 20 contains:

ConnectionBuilder myBuilder = ConnectionBuilder.connection()

            .url("https://[my-ip-for rhvm]/ovirt-engine/api")
            .user("admin@internal")
            .password("mypassword123")
            .trustStoreFile("/etc/pki/ovirt-engine/server.truststore")
            .trustStorePassword("myPassword123");

truststore is genearted using the steps mentioned in the Java_SDK guide.

Could you please help me to resolve this issue.
Not: I have installed the java sdk using , yum install java-ovirt-engine-sdk4

Thanks in advance.
