WARN - OpenmrsUtil.getRuntimePropertiesFilePathName(2438) |2012-01-19 11:46:30,460| Unable to find a runtime properties file at /home/harshadura/OpenMRS/Openmrs-trunk/webapp/openmrs-runtime.properties
ERROR - Listener.contextInitialized(154) |2012-01-19 11:46:35,015| Got exception while starting up:

Then, Create the "openmrs-runtime.properties" on the place mentioned by the jetty log. 

vim /home/harshadura/OpenMRS/Openmrs-trunk/webapp/openmrs-runtime.properties

And then put the below data into it. Note : Create the Database and give the necessary details into it. 

connection.username=open
connection.password=open
connection.url=jdbc:mysql://localhost:3306/openmrs?autoReconnect=true

Save and try a Jetty:run again! It should work.
