Installation Success but page 404

Hi, I was able to install Razuna 1.9.6 on Centos6.3. The tomcat page localhost:8080 works fine, but localhost:8080/razuna gives me the below error

“The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.”

The webapps dir contains the dir razuna
/opt/razuna/tomcat/webapps/razuna

What probably could be wrong??
