[Building Sakai] Req :- Need Terracotta server 3.7.6

Hello,

What's the difference between using Terracotta instead of using Apache with mod_jk?

I think they are used for the same purpose, load balancing and scalability. 

Correct me if I'm wrong.

Thank you.

Kumar,

Here’s a simple step-by-step to get Terracotta up and running:

	• Download Terracotta 3.7.6 (works with older version of ehcache, currently 2.6.6, in Sakai): http://d2zwv9pap9ylyd.cloudfront.net/terracotta-3.7.6.tar.gz
	• Get a license for the free version: http://terracotta.org/downloads/bigmemorymax/free
	• Untar the Terracotta files ({TERRACOTTA_DIR})
	• In the {TERRACOTTA_DIR} directory,
		• copy the license key file from #2 here
		• create a tc-config.xml file based on {TERRACOTTA_DIR}/config-samples/tc-config-express-reference.xml
		• sample tc-config.xml: https://dl.dropboxusercontent.com/u/282240/tc-config.xml
	• To start terracotta: {TERRACOTTA_DIR}/bin/start-tc-server.sh -n <NAME_OF_SERVER>
	• (OPTIONAL) To start the dev console monitor: {TERRACOTTA_DIR}/bin/dev-console.sh

Hi All,
         I have applied patches of session replication (distribute cache with terracota) on my sakai code base . 

 On starting up the tomcat server, i am getting below specified error, also i tried to download the terracotta server 3.7.6 version and i could not find it and that is why i am using 3.7.7 version. So could any one please help to get the "Terracotta server 3.7.6" or any suggestion to over come this issue will be great.
