Hi there, I have downloaded JCS (latest version I believe), and I have had some limited success with it. I am using TCPLateral cache, since I don't know of any available directories in production where it can store messages...
So, I am using this TCPLateral cache instead, my questions are: 1) I have deployed a small web app on two different machines, and could see from the log messages that they are "discovering" each other. This is all good and well, but when I stick something into the cache on machine A, I see that value in another servlet on machine Ano problem (JCS is static). However, I do NOT see that same value on machine B (same program, same cache name, same config ccf file etc..). So the quesiton is: What is the real purpose of the networking and "discovery" functions of TCP Lateral cache, if I am NOT able to see that same cached value on ALL my machines which are using the cache with the same config, same net etc...??? 2) If in question 1, I AM able to use TCP Lateral cache as a true distributed cache, what would a "proper" cache config look like? 3) What is the preferred and simplest way to do distributed caching?? 4) Is there a simple "hello world" for a distributed cache, including code and config? I am including a copy of my config on machine A and machine B. Thank you.
