Re: [Dev] Tomcat Session Replication Using Caching

Thanks for the insight. New implementation is based on the approach of single Hazelcast cluster shared across all webapps and context param (similar to /distributer tag) based approach to enable/disable session replication. On Tue, Oct 14, 2014 at 11:10 AM, Kishanthan Thangarajah

Re: [Dev] Tomcat Session Replication Using Caching

​​ Hi Azeez/Srinath I've managed to implement Tomcat Session replication using Hazelcast APIs. As per the off-line chats with Azeez and Sameera,This functionality is applicable to all web applications which are deploy in WSO2 AS. I've introduced a global web filter, which is define in the web.xml

Re: [Dev] Tomcat Session Replication Using Caching

Is a Hazelcast cluster created per webapp, or is a single cluster shared across all webapps? Why did you drop the idea of using a SessionListener SessionManager? On Mon, Oct 13, 2014 at 7:57 PM, Pubudu Dissanayake pubu...@wso2.com wrote: ​​ Hi Azeez/Srinath I've managed to implement Tomcat

Re: [Dev] Tomcat Session Replication Using Caching

I haven't drop the idea of using HttpSessionManager but what i thought was to evaluate how extent we can use this feature as a global web filter and HttpSessionListener is already placed in the global filter. In the current implementation Hazelcast creates a cluster per webapp, but I'm in progress

Re: [Dev] Tomcat Session Replication Using Caching

Hi Pubudu, Just to be clear, this feature should work on per webapp basis. i.e not all webapps' sessions should be replicated, but the selected ones by the user. Earlier we used a webapp context property (distributable) to enable this at webapp level. Also here are the test cases that comes to

[Dev] Tomcat Session Replication Using Caching

Hi All, I am working on an improvement for Carbon to enable tomcat session replication support using caching .Our previous implementation was based on a Tomcat Valve ( CarbonTomcatSessionReplicationValve.java).And it was used to replicate the session and adding it to cluster message. Http

We need to use Hazelcast When implemented we need to test this with multilple nodes (at least 4) and in high load conditions before it is done done. --Srinath On Wed, Oct 1, 2014 at 8:52 AM, Dinesh J Weerakkody dine...@wso2.com wrote: Hi, I came across this project [1] and might be useful.

Hi Srinath Hazelcast WM allows us to cluster user http sessions automatically. Followings are required for enabling Hazelcast Session Clustering http://hazelcast.com/use-cases/web-session-clustering/ [2][3] - Target application or web server should support Java 1.5+ - Target application or
