You may find following tips useful when setting up continuous integration infrastructure. Security Use VPN or reverse proxy provider like cloudflare.com to secure your CI infrastructure. Never make your real IPs publicly available, otherwise you increase a risk of being hacked. Jenkins Use master node and build agents. Master node acts only as web console. Nodes are for compiling and testing. Notifications If you’re using google apps for domain, you may use Google’s restricted SMTP server to send notifications.

Very often there is a need to monitor the Java application server. For example, external monitoring tool, like Nagious/Zenoss/Zabbix needs to get some metrics, like heap memory usage or thread count.
Usual way to get that metrics is to setup access to application server via JMX.
But, sometimes, it is not possible to leave some other port opened for JMX and the only port available is HTTP(80 or 8080) or HTTPS(443 or 8443).
Here the Jolokia comes to rescue!
