Hazelcast Integration Issue - [WebLogic 12c ] - hazelcast

Question

I am facing an issue during integration Hazelcast with weblogic 12c. Do i have to change any configuration?
com.hazelcast.instance.NodeExtension
com.hazelcast.instance.DefaultNodeExtension
Step 1: [setDomainEnv.cmd] i have added the path for
SET CLASSPATH=%CLASSPATH%E:lib\hazelcast-all-3.7.1.jar;
Step 2: I have written a sample start-up class for weblogic server
public class HCServer {
public HCServer() {
HazelcastInstance hz = Hazelcast.newHazelcastInstance();
}
public static void main(String[] args) {
try {
Class.forName("server.HCServer").newInstance();
Set<HazelcastInstance> set = Hazelcast.getAllHazelcastInstances();
for (HazelcastInstance hcInstance : set) {
IMap<String, HCTask> iMap = hcInstance.getMap("data");
for (int i = 0; i < 5000; i++) {
iMap.put(String.valueOf(i), new HCTask(i));
}
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
Following error occurs on starting the server

Answer 1

Do you want to fix constructor of HCServer like this
public HCServer() {
Config config = new XmlConfigBuilder().build();
config.setClassLoader(this.getClass().getClassLoader());
HazelcastInstance hz = Hazelcast.newHazelcastInstance(config);
}
Let me know if it works!
