Im not a expert. I have little knowledge about these ports. Whenever Im trying to change netbean's apacahe tomcat ports it shows port is in use (tried ports: 9893,3435,8021,8080,80 etc).
How can i fix the conflict between these ports ? I also have glass fish server which come with netbeans full installation. I think this also have port issuies.
When I type localhost:8084 a page with some error shows up. Here's a image of that :

Whats wrong with the installation ? How can I give full read/write permissions to apache webapps folder?
netstat -atpnas root (orsudo netstat -atpn). This will show you which process is listening on which port. Then, check if you need all of the servers running. There seem to be Tomcat, Glasfish and Mono running in parallel - is this required? Does Netbeans need two servers (Tomcat, Glassfish)? – tohuwawohu Apr 18 '12 at 9:41
