Sonar throws exception when starting on Tomcat 6 running on OS X Server

Question

I've deployed the sonar 3.3 warfile with the proper DB config to a working Tomcat 6 on my MacOS server: ``` System Version: Mac OS X 10.7.5 (11G63) Kernel Version: Darwin 11.4.2 ``` When it tries to deploy the war I get this: ``` [pool-2-thread-1] ERROR jruby.rack - Error: application initialization failed org.jruby.rack.RackInitializationException: java.lang.NullPointerException: null from org/sonar/server/ui/JRubyFacade.java:447:in `getServerHome' from /usr/local/tomcat/temp/0-sonar/WEB-INF/config/environment.rb:52:in `(root)' from /usr/local/tomcat/temp/0-sonar/WEB-INF/gems/gems/rails-2.3.14/lib/initializer.rb:111:in `run' from /usr/local/tomcat/temp/0-sonar/WEB-INF/config/environment.rb:32:in `(root)' from org/jruby/RubyKernel.java:1058:in `load' from /usr/local/tomcat/temp/0-sonar/WEB-INF/config/environment.rb:23:in `load_environment' from /usr/local/java/apache-tomcat-7.0.23/work/Catalina/localhost/sonar/loader/jruby/rack/rails_booter.rb:65:in `load_environment' from <script>:1:…

you need to point the SONAR_HOME env variable to the directory where you unpacked and build the sonar war

Example:

download sonar distribution

```
wget "http://dist.sonar.codehaus.org/sonar-3.2.zip"
```

build the sonar.war, Note: the sonar.war will be bound to the directory where it has bean build

```
unzip sonar-3.2.zip -d ~/temp/sonar
mkdir /home/ubuntu/.sonar
mv ~/temp/sonar/sonar-3.2/* ~/.sonar
cd ~/.sonar/war/
./build-war.sh
cd ~
```

deploy sonar to tomcat mv ~/.sonar/war/sonar.war ~/java/servers/sonar-tomcat-6.0.35/webapps/sonar.war

cleanup - but do not delete the ~/.sonar/ cause that is the sonar_home

```
mv sonar-3.2.zip ~/java/utils/zip/
rm -rf ~/temp/sonar
```

configure tomcat for running sonar see mkyong

```
printf 'CATALINA_OPTS="-Xmx1024m -Dorg.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true -XX:MaxPermSize=256m"
' | tee ~/java/servers/sonar-tomcat-6.0.35/bin/setenv.sh
printf 'SONAR_HOME="~/.sonar"
' | tee ~/java/servers/sonar-tomcat-6.0.35/bin/setenv.sh
```
