Hi folks,
I have a JRuby on Rails deployed natively on GF V3 Prelude and looking for a loadbalancing solution. I have read several blogs but none of them is referring to V3 Prelude...
http://weblogs.java.net/blog/jfarcand/archive/2006/03/running_glassfi_1.html
http://blogs.sun.com/kshitiz/entry/load_balancer_plugin_in_glassfish
I have also tried using mod_jk but it gives me the following error during server start after enabling -Dcom.sun.enterprise.web.connector.enableJK=xxx option. (I do have those 3 jar files copied to $GF_HOME/lib)
Can somebody here advise what the loadbalancing solution should be for V3 Prelude, especially with a JRuby on Rails ? Thanks a lot!
Calvin
