Setting Context-Root with Glassfish Application Server - glassfish

Question

I have a EJB WEB Application with an Glassfish Application-Server.
Now i want the Context-Root like this "/".
My current URL is "http://localhost:8080/Make"
but i want this one :"http://localhost:8080" without the "Make" as my Application Name currently is. But hen i deploy it and tip "http://localhost:8080" i got the "Server is running" page from glassfish
So i trie to figure out what i can do. I have create a glassfish-web.xml in my WEB-INF folder
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish- web-app_3_0-1.dtd">
<glassfish-web-app error-url="">
<context-root>/</context-root>
</glassfish-web-app>
Nothing happens. Than i have create a sun-web.xml in the same folder:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sun-web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD GlassFish Application Server 3.0 Servlet 3.0//EN"
"http://www.sun.com/software/appserver/dtds/sun-web-app_3_0-0.dtd">
<sun-web-app error-url="">
<context-root>/path/to/our/App</context-root>
</sun-web-app>
Also i hvae trie with a glassfish-application.xml and application.xml.
So what must i do to take this effect?
PS: this is my web.xml and i deploy as EAR file
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

Setting the context root to / is not enough to be able to access your web app only by typing http://yourdomain.org because Glassfish will display the "Your server is running" message found in index.html`.
To get your app launch. set the Default Web Module drop down found in Configuration | server-config | Virtual Servers | server (in the Web console) to the name of your web app.

The glassfish-web.xml you posted seems to be ok.
If you deploy you application as EAR, you may need and application.xml like this:
<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_6.xsd" version="6">
<application-name>something</application-name>
<display-name>something</display-name>
<module>
<web>
<web-uri>your_webapplication.war</web-uri>
<context-root>/</context-root>
</web>
</module>
<module>
<ejb>your_ejb_services.jar</ejb>
</module>
<library-directory>lib</library-directory>
</application>
This is just a template example. You can also have multiple web-modules and ejb-modules.
If you deploy via the Glassfish Admin UI you can set the context root when deploying:
If you use asadmin for deploying you can set the context root like this:
asadmin deploy --name something --contextroot / /path/of/your/war.war

I hope I am not late I have struggled with the same problem. For a while now and no matter what I tried the server spit out the default your your server is running page.
What needs to be done to be able to visit example.com without having to enter example.com/example where example is the contextroot defined in your glassfish-web.xml is ip tables rerouting and can be accomplished as follows.
Assuming you are on ubuntu server 20.04LTS execute below commands as root
root#example.com:~$
root#example.com:~$ iptables -A INPUT -p tcp --dport 80 -j ACCEPT
root#example.com:~$ iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 8080
root#example.com:~$ iptables -A INPUT -p tcp --dport 443 -j ACCEPT
root#example.com:~$ iptables -t nat -A PREROUTING -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8181
You have to make this permanent:
root#example.com:~$ iptables-save -c > /etc/iptables.rules
root#example.com:~$ iptables-restore < /etc/iptables.rules
And call during startup,
root#example.com:~$ vi /etc/network/if-pre-up.d/iptablesload
Copy and paste below commands into the iptablesload file opened by vi
above
#!/bin/sh
iptables-restore < /etc/iptables.rules
exit 0
Don't forget to make iptablesload executable with
root#example.com:~$ chmod +x /etc/network/if-pre-up.d/iptablesload!
