What we’ll cover • Ant • WAR • JRun

Apache Ant • Automated build system • Java based • XML conﬁguration

Why Automated Builds? • Repeatable • Predictable • Scalable

Why Ant?

Why Ant? • Familiar • Java • Eclipse • XML • SSH/HTTP

Web Application aRchives

Web Application aRchives “JAR file used to distribute a collection of JavaServer Pages, servlets, Java classes, XML files, tag libraries and static Web pages (HTML and related files) that together constitute a Web application.” http://en.wikipedia.org/wiki/WAR_(Sun_file_format)

Web Application aRchives

Web Application aRchives • Special kind of JAR (which is a special ZIP)

Web Application aRchives • Special kind of JAR (which is a special ZIP) • Directory structure (compressed or not)

JRun Conﬁguration

JRun Conﬁguration • {jrun}/lib/servers.xml • Which servers are conﬁgured? • Where does each server live?

Server Conﬁguration

Server Conﬁguration • {jrun}/bin/jvm.conﬁg • Path to JRE • VM args - memory, GC • Classpath

Server Conﬁguration • {jrun}/bin/jvm.conﬁg • Path to JRE • VM args - memory, GC • Classpath • Can have one per server

Server Conﬁguration • {server}/SERVER-INF/jrun.xml • Metrics & logging • Deploy directory • HTTP WebService & ProxyService ports

Server Conﬁguration • {server}/SERVER-INF/jrun.xml • Metrics & logging • Deploy directory • HTTP WebService & ProxyService ports • Beware of port conﬂicts

Server Conﬁguration • {server}/SERVER-INF/jndi.properties • Java Naming Service (JNDI) port • Used for clustering

Application Conﬁguration

Application Conﬁguration • {app-name}/WEB-INF/jrun-web.xml • <context-root>/</context-root> is missing by default • Applications run under /{app-name}

Application Conﬁguration

Application Conﬁguration • {app}/WEB-INF/cfusion/lib/neo-*.xml • All settings for CF Administrator • Caching, Memory, Verity, Data Sources, Mail, etc

Creating a new server

Creating a new server • Creates /opt/jrun4/servers/deploy containing

Creating a new server • Creates /opt/jrun4/servers/deploy containing • default-ear

Creating a new server • Creates /opt/jrun4/servers/deploy containing • default-ear • SERVER-INF

Creating a new server • Creates /opt/jrun4/servers/deploy containing • default-ear • SERVER-INF • Delete default-ear application

Creating a new server • Point Apache at the new server

WAR Deployment uses Ant

Integrating with our build

Example: Deploying a WAR

Example: Deploying a WAR • <antcall>

Example: Deploying a WAR • <antcall> • <sleep>

Example: Deploying a WAR • <antcall> • <sleep> • <war>

Recap • Created empty JRun server

Recap • Created empty JRun server • Created WAR containing empty CF instance

Recap • Created empty JRun server • Created WAR containing empty CF instance • Integrated with Ant build

Recap • Created empty JRun server • Created WAR containing empty CF instance • Integrated with Ant build • Deployed WAR into JRun server along with CF code

Why bother?

Cons • Up front cost

Pros • Save time

Pros • Save time • Prevent errors & inconsistencies
