+WebApp Load Balancing Demo
+===========================
+
+Demonstrates balancing load acoss SCA services by deploying an SCA composite
+to two tomcat servers in a cluster. The tomcat servers sit behind an Apache
+server which directs load to one or other tomcat server based on a set of rules.
+
+The mvn pom distributed with this sample will download, install and configure
+two Tomcat servers automatically to act as workers. You need to install the
+Apache web server and configure it manually.
+
+1 - Install and configure the Tomcat workers
+
+mvn
+
+This results in two tomcat servers at
+
+target/tomcat-8085
+target/tomcat-8086
+
+2 - Install and configure the Apache server to balance load
+
+In this case we've chosen to use the native JK connector. There are several
+resources that tell you how to configure Apache for load balancing Tomcat with
+the JK connector. For example,
+
+http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html
+http://www.crazysquirrel.com/computing/debian/servers/tomcat55.jspx
+
+Here is a high level summary
+
+Download the latest version of Apache 2.2 (this demo was built with Apache 2.2.6)
+ http://httpd.apache.org/
+ Install in a local director called, say, apache
+
+Download the mod_jk module (in binary form if you can)
+ http://tomcat.apache.org/download-connectors.cgi
+ Install it in apache/modules
+
+Configure the mod_jk module
+ Copy src/test/resources/apache-80/conf/workers.properties to apache/conf
+ Append the contents of src/test/resources/apache-80/conf/httpd.conf to apache/conf/httpf.conf
+
+3 - Start the apache and tomcat servers
+
+In three command prompts
+
+cd target/tomcat-8085
+bin/catalina run
+
+cd target/tomcat-8086
+bin/catalina run
+
+cd apache
+bin/httpd
+
+4 - Run the client
+
+run the LanchClient program - TBD - need a script
+
+5 - Result
+
+The client will make 10 calls to the SCA service described in the helloworldws.composite that
+is part of the webapp deployed to the tomcat servers. You will see the result of this
+service call reported at the client in the form
+
+Called getGreetings
+Hello World 6
+
+If you look at the Tomcat consoles you will see that each server deals with half the requests
+as the load is balanced equally between the two of them.
