Hi,
I’m trying to set up a data grid on AWS ECS.
I was able to get JCache working with these tutorials:
> **[Get Started with Embedded Hazelcast on ECS](https://docs.hazelcast.com/tutorials/ecs-embedded)**

But session replication is not working. I developed a very simple JSF webapp to test based on the hajspcluster demo, it has on web.xml and the session attributes are serializable.
What am I missing?
Thanks
Session test application code:
```auto
Facelet Title
Key
Value
- server:
- session id:
- Served From Server instance: #{indexBean.instanceName}
- Executed Server IP Address: #{indexBean.hostAddress}
#{item.key} - #{item.value}
```
```auto

public class IndexBean implements Serializable {

private String value;
/**

public IndexBean() {
}
public void add()
{
getSessionMap().put(key, value);
System.out.println(getSessionMap());
}
public String getInstanceName()
{
return System.getProperty("com.sun.aas.instanceName");
}
public String getHostAddress()
{
try {
return java.net.InetAddress.getLocalHost().getHostAddress();
} catch (UnknownHostException ex) {
return ex.getMessage();
}
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public Map getSessionMap() {
return FacesContext.getCurrentInstance().getExternalContext().getSessionMap();
}
}

HI @fkj,
We have a blog written regarding setting up session replication in Payara Server, although the blog is written as part of a series using Apache web server, the setup should still be applicable when using AWS ECS.
The blog can be found here: [Session Replication in Payara Server with Hazelcast](https://blog.payara.fish/session-replication-in-payara-server-with-hazelcast)
If you are still unable to configure session replication after following that blog, I will gladly take a further look.
Thanks,
James

I followed these steps.
I can see some action at the logs, but when I stop one of the two instances of the test the session is lost

I was able to get this working by using hazelcast-wm, but I’m still interested in using payara’s embedded hazelcast.
Anyone?
