Tomcat clustering

Hi Guys!

What means the following error? What I'm doing wrong?

FINE: Assuming clocks are synched: Replication for GET-ALL- took=47 ms.

Thanks a lot

That's not clustering - it's just two separate Tomcat installations.  Clustering is defined as the *same* applications cooperatively deployed on multiple Tomcats.

Andrew,

Sharing state between web apps in Tomcat is possible with solutions like
Terracotta or a customized messaging system.

Re: Tomcat clustering

Posted by Filip Hanik - Dev Lists <de...@hanik.com>.
but you are saying they are different applications, so what data could 
they possible share?

ie, if you have appA.war and appB.war, and they are totally different 
apps, then they shouldn't be sharing session data

only appA.war on one tomcat instance can share session data with 
appA.war on another tomcat instance

Re: Tomcat clustering

Posted by Andrew Hole <an...@gmail.com>.
Well,

I would like in the future to have application A and B in different
machines, and for that i need to use some way to share session data.

Thanks

Re: Tomcat clustering

nothing like that is built in, you'd have to write that code for the 
object sharing yourself
you could use the tomcat internals to achieve what you want, but you'd 
have to do a bit of legwork.

Re: Tomcat clustering

Posted by Andrew Hole <an...@gmail.com>.
Yes.

Machine1
 TomcatA
  ApplicationA1
 TomcatB
  ApplicationB1

But both applications have been developed by me and I want to share an
object between applications. If the object have been created in application
A, I would like to replicate information to application B.

Thanks

Re: Tomcat clustering

not sure I understand

Is this your layout then?

 Machine1
  TomcatA
    ApplicationA1
  TomcatB
    ApplicationB1

since ApplicationA1 and ApplicationB1 are different, there is nothing to 
cluster, there is no state to share

I would like to cluster two different applications in same machine (each in
different Tomcat instance).
Is it possible?

Re: Tomcat clustering

It means that the application that it is trying to request data from is 
not deployed on the server.

for example, if you have applicate /test installed on server A, then it 
will have to be installed on server B as well, if it isn't, you'll get a 
message like the one below
