go to your browser (i used google chrome)
type 192.168.178.56:9090/portal (dont type this 192.168.178.56  type your

wait a little dont be dissapointed (i was because my laptop is too slow)

apply after to be sure the following (just to be sure lol):

export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$PATH:$JAVA_HOME/bin
export CATALINA_HOME=/opt/tomcat
export PATH=$PATH:$CATALINA_HOME/bin
export SAKAI_HOME=/opt/tomcat/sakai
export JAVA_OPTS='-server -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m -XX:NewSize=192m -XX:MaxNewSize=384m -Djava.awtECHO.headless=true -Dhttp.agent=Sakai -Dsakai.home=/opt/tomcat/sakai -Dorg.apache.jasperRT.compiler.Parser.STRICT_QUOTE_ESCAPING=false -Dsun.lang.ClassLoader.allowArraySyntax=true'

then go to

root at ubuntu2011new:~# cd ..
root at ubuntu2011new:/# cd opt/tomcat/bin/
root at ubuntu2011new:/opt/tomcat/bin# ls
bootstrap.jar                  i64                    tomcat5.exe
catalina.bat                   jmxaccessor-tasks.xml  tomcat5w.exe
catalina.sh                    service.bat            tomcat-juli.jar
catalina-tasks.xml             setclasspath.bat       tomcat-native.tar.gz
commons-daemon.jar             setclasspath.sh        tool-wrapper.bat
commons-daemon-native.tar.gz   shutdown.bat           tool-wrapper.sh
commons-logging-api-1.1.1.jar  shutdown.sh            version.bat
cpappend.bat                   startup.bat            version.sh
digest.bat                     startup.sh             x64
digest.sh                      tcnative-1.dll
root at ubuntu2011new:/opt/tomcat/bin# sh startup.sh

(then you have the following)

Using CATALINA_BASE:   /opt/tomcat
Using CATALINA_HOME:   /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME:        /usr/lib/jvm/java-6-sun
Using CLASSPATH:       /opt/tomcat/bin/bootstrap.jar

go to your browser (i used google chrome)
type 192.168.178.56:9090/portal

wait a little dont be dissapointed (i was because my laptop is too slow)

and SUCCESS!!!!!!!!

(if somebody can put all the enviromental variables somewhere so as not to copy them every time and share it please do)
