How to successfully connect to OrientDB-TP3 in a Java project?

[zhengyingying]

I install OrientDB-TP3-3.2.10, and want to access it remotely with Java codes.

The orient.yaml in my java project is:

hosts: [192.168.1.102]
port: 8182
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV3d0, config: { ioRegistries: [org.apache.tinkerpop.gremlin.orientdb.io.OrientIoRegistry] }}

I want to use the following code to access gremlin server.

String file = this.getClass().getClassLoader().getResource("conf/orient.yaml").getPath();
cluster = Cluster.open(file);
client = cluster.connect();

But it throws an exception.

Could not establish serializer - org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV3d0

So, how to solve this problem?
