I had this problem on an older Ubuntu Server, so I did a fresh install and installed Alfresco 3.3a x64.
The problem is that when I go to the login page, I get:
The remote server may be unavailable or your authentication details have not been recognized.
If I go to /alfresco I get:
The requested resource () is not available.
I have looked through the Tomcat logs and have found:
SEVERE: Error listenerStart
The way I installed this was using the latest installer from dev.alfresco.com. Installation was painless. I installed the latest JDK from sun and set the $JAVA_HOME from the bash:
(in bash.bashrc)
JAVA_HOME="/usr/java/jdk1.6.0_21"
export JAVA_HOME
I have spent entirely too much time trying to get this installed. Help?
