Very well organized tutorial and very detailed. Thank you very much Mr. Ramki!

Tomcat is definitely one of the best and easiest J2EE App Server/Container to use
compared to other products like Weblogic and Websphere. And furthermore it is free of charge unlike the 2 so-called enterprise products above that come with a ridiculous price tag to put someone into COMA.

Hi Ramki,

I have been watching your videos.

We have Tomcat 9 with 2 nodes and session replication does not work.

Could you please share the steps that I need to follow to set up session replication on Tomcat 9?

[karnifazil]

Rama, thank you very much for sharing this video. Its very informative. I have a follow up question. Is it possible to use apache as workers instead of tomcat? the reason is below every worker I want to have another level of workers. If yes please point me to the documentation.

[santoshharne]

Really appreciate you that way you are presenting. I just want to know that same steps will work for tomcat9 ?

[SoftwareSimplified-Dtons]

[abhineshkumar]

As Working with Tomcat 9 on windows machine multiple tomcat on single machine. Not replicating session. How to debug? Will this work on windows machine . Also getting error for Class not found exception. Please do help.

Rama - were you able to test session replication on tomcat version 8 clustering using mod_jk ?

[RamakrishnnanEP]

r u put distributable tag inside web.xml file?

please elaborate the problem? what u did and which step is showing problem?

[RamakrishnnanEP]

U need to add route line irrespective of ur IP address. because multicast address is class D address range. (224.0.0.0 to 239.255.255.255). so u should select this address range only.
so the route line command common for all IP address

[sudarshanreddye]

whenever I am doing this not able to add tomcat server into eclipse.its showing there is no conf file.how can i resolve

[TheBestDieEarly]

on my machines only the SessionID and attributes are replicated, but not the values. What does that mean?
Are you planning a new tutorial with Tomcat 8 ++

[SoftwareSimplified-Dtons]

Hi Rama , Firstly Thanks for the great explanation in Part One and Part Two In this Part 3 i have one doubt can you
please tell me how to enable Multicasting for Windows at 7:33

Thank you in advance

[marcf]

Rama, I have this configured usin Members instead multicast, but it's not runing fine. Particularly when a tomcat shut down because the machine stop running.
In that case I had some errors in log like "No route to host", bla, bla. Do you have that case as an example? A mean, using StaticMembershipInterceptor as an interceptor instead Multicast! How could I contact you? Warm regards, Marcelo
