HTTP session is not getting reflected in infinispan

[Harshit Bhuva]

Hi Team,

Below are my requirement
I have four standalone wildlfy 20 server.
I want to store HTTP session and local cache + L2 cache in remote infinispan cluster server.
I tried with your configuration which is here shared but still I am not able to store HTTP session on infinispan server.
Kindly suggest steps for the configuration part.

For HttpSessions:

https://github.com/wildfly/wildfly/blob/main/docs/src/main/asciidoc/_high-availability/subsystem-support/Distributable_Web_Applications.adoc#hotrod-session-management

https://github.com/wildfly/wildfly/blob/main/docs/src/main/asciidoc/_high-availability/subsystem-support/Infinispan_Subsystem.adoc#remote-cache-container

Infinispan does not include a 2LC implementation that uses a remote infinispan cluster, rather it is implemented as a local invalidation cache.

Otherwise, you'll want to use something like Hibernate OGM.

Hi Paul,

As discussed earlier I have gone through one of your email threads and I found out that the configuration which I have shared below works for HTTP session replication to remote infinispan cluster server.

But I tried the same but it's not working for me.

Below is my scenario

1. Login with two different users on two different nodes (USER1 -> NODE1 AND USER2 -> NODE2).

2. Now shutdown NODE1

3. If I refresh the application page of USER1 then I should not get any logout page rather it should be redirected to node2, which is not happening with my case. I am getting a re-login page with a session timeout message.

Please help me with the configuration if I have missed something.

I am using wildfly 20 and infinispan 10.1.8 (remote server as of now single node)

Below are my configuration

I have added below configuration in my both standalone.xml (standalone server 1 and standalone server2)

<subsystem xmlns="urn:jboss:domain:infinispan:10.0">

Is your web application distributable? i.e. does it specify <distributable/> within web.xml?

[Harshit Bhuva]

Hi Paul,

I have multiple standalone wildfly servers which are accessed via load balancer (Apache).

My server is not in cluster mode. Also I have not added <distributable/> within web.xml.

There's your problem.  You web application's /WEB-INF/web.xml must contain <distributable/>.  This is a servlet specification requirement needed to enable wildfly's distributed session manager.

[Harshit Bhuva]

Hi Paul,

Thanks for your reply.

I did the changes in web.xml and added 

<distributable/> and have started the server.

But now at the end of the server log I am getting error message saying few of the service failed to start. And I am unable to access my application page.

Hey Paul,

Any other configuration I need to change?

Please paste the relevant exceptions from the log.

Can you include the exceptions logged for those services that failed to start?
