Java/Hibernate ant build example

This is the contents of a typical ant build file I use for Java coding projects. It’s up here in case it can help anyone else, and so I can copy and paste it when working off-site.

The process is fairly simple, I have my working area in a ~/projects/myapp folder (where myapp is name of current project). I have lib files in ~/projects/java/lib/

I run the build in the myapp file, the ant file reads the build.properties file for some config info and dumps the build outputs to the $targetdir folder (~/projects/bin)

Firstly, the build.properties file

# options: linux, windows, mac
gwt.os = linux

#Directories
gwt.installation.dir = ~/google/gwt-windows-1.5.3
#note env is defined in build.xml file
gwt.dir=${env.GWT_HOME}
tomcat.dir=${env.TOMCAT_HOME}
hibernate.dir=${env.HIBERNATE_HOME}
postgresql.dir=${env.POSTGRES_HOME}
asm.dir=${env.ASM_HOME}
spring.dir=${env.SPRING_HOME}
loglib.dir=${env.LOGLIB_HOME}
junit.dir=${env.JUNIT_HOME}

#JAR files
servlet.api.jar=${tomcat.dir}/lib/servlet-api.jar
gwt.servlet.jar=${gwt.dir}/gwt-servlet.jar
hibernate3.jar=${hibernate.dir}/hibernate3.jar
postgresql.driver.jar=${postgresql.dir}/postgresql-8.3-604.jdbc4.jar
asm.jar=${asm.dir}/asm-3.1.jar
loglib.jar=${loglib.dir}/commons-logging-1.1.1.jar
junit.jar=${junit.dir}/junit-4.5.jar
#google web toolkit jars
gwt.user.jar = ${gwt.installation.dir}/gwt-user.jar
gwt.servlet.jar = ${gwt.installation.dir}/gwt-servlet.jar
gwt.dev.jar = ${gwt.installation.dir}/gwt-dev-${gwt.os}.jar
build.dir = ../build
classes.dir = ${build.dir}/classes
jar.dir = ${build.dir}/jar
gwt.output = ${build.dir}/www

sourcedir = ${basedir}/src
targetdir = ${basedir}/bin
includedir = c:/projects/java/lib
testdir = ${basedir}/test
resdir = ${basedir}/res
reportsdir = ${basedir}/reports
appdir = ${basedir}
wwwdir = ${appdir}/www/com.petermac.${app}
spring.conf.dir = ${basedir}/src/META-INF/spring
hibernate.conf.dir = ${basedir}/src/META-INF/hibernate

Now for the actual ant file. This is specific to a GWT application, but you can easily knock out the google bits and use the rest without any changes.

<?xml version="1.0" encoding="utf-8" ?>
<project name="ClaimsManager" default="compile" basedir=".">
<property name="TALK" value="false" />

<property environment="env" />

<property file="build.properties" />
<description>
ClaimsManager build file. This is used to package up your project as a jar,
if you want to distribute it. This isn't needed for normal operation.

Meet “Java”, a new addition to the PeterMac team.

java at 9 weeks

Although only 9 weeks old, she shows great focus in object oriented design (she chases any object that moves). She’s got an excellent grasp of string manipulation technniques and we have to agree that her display of experience in the J2SE (Sleeping and Eating) area is beyond expectations for one so young.

Minister for misCommunication

A recent brain-fart by the Australian Minister for Communications, Helen Coonan, has exemplefied why Australia remains a relative technology backwater. She said that she expects people ought to be happy with existing Internet speeds.

“Well they ought to be in Sydney, Melbourne, Adelaide, Brisbane, certainly and Perth,” she said.

“They should be reasonably happy with their speed of broadband, if they have ADSL 2 Plus.

“There are nine providers that already provide these speeds.”

This outburst happened as a result of an announcement by Telstra (the 51% government owned body responsible for maintaining the telecomms infrastructure) that it was pulling out of a proposed fibre optic upgrade to existing networks.

Indeed there is access to ADSL 2+ in these cities but no thanks to Government support. The roll-out has been excruciatingly slow and is only available in higher population density areas. It (the ADSL2 network)has been taken on by a consortium of private companies with the previous threat of the Telstra upgrade having the potential to render their effort futile.

For a Minister of Communications to make such a generalised and uninformed comment smacks of a level of ignorance that can only come from some-one whos’ tenure in the role is transient. Be warned, your communications minister does not have the best interests of Australian Internet users at heart.

Statistics from the OECD show Australia in 18^th place in terms of broadband take-up. Although this is not a reflection of Internet speeds, it is a reflection on the perceived cost/benefit available to Australian consumers. Get your act together Minister!
