Question

GlassFish -I cant reach Admin console page

  • Posted August 6, 2014

Hi everyone,

i just came up digital ocean and im trying to deploy a java web app. I took the SSH .

i can reach the server with putty no problem.

My droplet working no problem. Im installed glassfish 4.0 with these instructions:

https://www.digitalocean.com/community/tutorials/how-to-install-glassfish-4-0-on-ubuntu-12-04-3 and set enable-secure-admin and restarted.

my problem is that when i tried to : http//myip:8080 it says no problem glassfish server is running. (like when i using netbeans localhost) but when i try to access http://myip:4848 login page and i giving id and password but console never opening. (im sure my glassfish server admin and password is true) . and moreover when i came to putty domain1 has stopped. Im thinking its due to ubuntu firewall ?

Can anyone help me ?

Greetings,

I`m having the same problem… Checked ports:

Starting Nmap 7.01 ( https://nmap.org ) at 2018-07-17 00:51 UTC Initiating Parallel DNS resolution of 1 host. at 00:51 Completed Parallel DNS resolution of 1 host. at 00:51, 0.18s elapsed Initiating SYN Stealth Scan at 00:51 Scanning IP [1000 ports] Discovered open port 22/tcp on IP Discovered open port 3306/tcp on IP Discovered open port 80/tcp on IP Discovered open port 8080/tcp on IP Discovered open port 4848/tcp on IP Discovered open port 7676/tcp on IP Discovered open port 8181/tcp on IP Completed SYN Stealth Scan at 00:51, 1.57s elapsed (1000 total ports) Nmap scan report for IP Host is up (0.000015s latency).

Already installed JDK and the Glassfish, didn`t touch on iptables and when I try on browser ip:8080 or ip:4848 I get this message: Is not possible to access the website. ip took too much time to answer. ERR_CONNECTION_TIMED_OUT.

Ubuntu doesn’t have a firewall enabled by default. Did you? It would certainly explain the issue you are seeing.

On the server, run sudo netstat -plunt | grep 4848 If it is running on port 4848, you should see:

tcp6       0      0 :::4848                 :::*                    LISTEN      3962/java

If you don’t then you know that GlassFish is not running properly, and the problem isn’t firewalling. If it is listed, run iptables -L to see your file wall settings and check that you are not blocking port 4848.
