Preparing Liferay EXT environment

• Install JDK and ANT.

• Set JAVA_HOME and ANT_HOME to your Ant and Java directories. Add JAVA_HOME\bin and ANT_HOME\bin to System Path.
• Create a Liferay directory:
  

$HOME/liferay-devel (refered as {LIFERAY}).

• Create a directory called:

{LIFERAY}/portal
and unzip de Liferay sources into it.

• Create a file called:

release.{user name}.properties, where {user name} is the user name used to develop.

• and put the next lines with the appropiate values:

lp.ext.dir={LIFERAY}/ext

• If you expect to be using eclipse add also a property called lp.eclipse.project.name with the desired name of the project:

lp.eclipse.project.name=liferay-ext

• Create a file called:

app.server.{user name}.properties

• and put the next lines with the appropiate values:

app.server.type=tomcat
app.server.tomcat.dir={LIFERAY}/tomcat
sourceforge.mirror=http://belnet.dl.sourceforge.net/sourceforge/lportal

• Create a file called:

build.{user name}.properties

• and put the next lines with the appropiate values:

javac.compiler=modern, for use Sun's compiler.
javac.fork=true

• Go into {LIFERAY}/portal directory an execute:

> ant clean
> ant start
> ant build-ext

This must create a directory {LIFERAY}/ext (or what you called in lp.ext.dir) and create your EXT environment.

• Copy files release.{user name}.properties, app.server.{user name}.properties and build.{user name}.properties to the {LIFERAY}/ext directory.

• Go to the {LIFERAY}/ext/servers and execute:

> ant install-tomcat
It must download and install a tomcat liferay bundle into {LIFERAY}/tomcat.

• The idea is to have:

{LIFERAY}
{LIFERAY}/ext -> Your EXT environment to develop.
{LIFERAY}/portal -> The portal sources used to create the EXT.
{LIFERAY}/tomcat -> The server (lifery bundle) used to develop.

• Now execute:

> chmod a+x {LIFERAY}/tomcat/bin/*.sh

• and try to start liferay bundle:

> {LIFERAY}/tomcat/bin/catalina.sh start

• Connect to http://localhost:8080 (user test@liferay.com, password test).
