I want to change the context-path of application in glassfish using linux.
I cannot access the 4848 of glassfish due to some restrictions, i can only access it thru linux.
You can change the port for the admin-listener in the domain.xml file:
<network-listener
protocol="admin-listener"
port="9000" // <-- change the port to your needs
name="admin-listener"
thread-pool="admin-thread-pool"
transport="tcp">
</network-listener>
Note: I did not test if the console commands work when you change the admin listener port. So you should test it in you DEV or TEST enviornment before.

I recently moved from macOS to WSL 2. I have two node servers running within WSL 2 (Ubuntu distro). Each must be accessible through a custom hostname for development vs production purposes. I've had difficulty accessing the node servers via custom hostnames (ie set in some ../etc/hosts file) especially given WSL 2's dynamic IP that changes per WSL/pc 'boot'. How does one go about setting custom hostnames in WSL 2?
Scenario:
Each node.js app server (again running within WSL 2) must be accessed from the browser with the following urls/custom hostnames:
www.app1.com:3010
www.app2.com:3020
After searching around I have found the following relatively simple process works. I thought I'd share and save some time and headache for those new to WSL 2. Note, although I'm using node as the server stack, this process should more or less be the same for other app/web server stacks.
Note the following SE post is the basis of the solution. It's also worthwhile to examine MSFT's reference on WSL vs WSL 2. Also note, I haven't provided deep rationale on why these steps are required, why we might need custom hostnames, ipv6 options in ../etc/hosts, the meaning of 127.0.0.1, loopback addresses, WSL 2 and distro management, etc. These are subjects beyond the scope of this post.
Simple scenario:
nodeApp1: node application server with custom hostname: 'www.app1.com' on port 3010 (or whatever)
nodeApp2: node application serverwith custom hostname: 'www.app2.com' on port 3020 (or whatever)
Each node.js app server (again running within wsl 2) can be accessed from the browser with the following urls:
www.app1.com:3010
www.app2.com:3020
Two key items:
The correct etc/hosts files to be modified is on the Windows side (not WSL distro) at: C:\Windows\System32\drivers\etc\hosts (yes in Windows folders). This is a 'hot' update so no need for WSL 2 reboot. The content for this scenario is:
127.0.0.1 localhost
127.0.0.1 www.app1.com
127.0.0.1 www.app2.com
255.255.255.255 broadcasthost
::1 localhost www.app1.com www.app2.com
Please add C:\Users\"you"\.wslconfig with the following content (yes in Windows folders):
[wsl2]
localhostForwarding=true
Note: there's a reference to this in WSL 2 Ubuntu distro's /etc/hosts.
Also note, this requires WSL shutdown and reboot. Shutting down your terminal is insufficient. Also total machine boot is not
required. Simply run:
wsl --shutdown (in Powershell) or
wsl.exe --shutdown (within Ubuntu)
Then restart the Windows Terminal app (or any WSL terminal) to access the updated WSL 2 environment. The apps with custom urls/hostnames will now work in the browser permanently and WSL 2's dynamic IP is circumvented.
Ive got 4 dev VMs for four projects (all VMware Player VMs w/ubuntu 15.04 host) where each is running VNC (ports 5900, 5901, 5902, 5903) respectively.
I downloaded noVNC and saved to /var/www/html (my apache2 server on same host). Based on the ReadMe I then ran on my terminal
./utils/launch.sh --vnc localhost:5900
I received a missing websockify error, so downloaded it and placed it into the util folder. I then ran the same command and it worked! The terminal told me to Navigate to a url and sure enough I could control my VM.
However -- I'm wondering how can I use noVnc to access all 4 VM's? Is there some simple way to extend the port to a range like in iptables or firewalld?
./utils/launch.sh --vnc localhost:5900-5903
Okay, Ill answer for myself here in case it helps someone in the future...
First, create a token file where each line has a nickname, ip address, and port.
I created a file named token.list where each line looks like:
localhostnickname1: localhost:5900
localhostnickname2: localhost:5901
...
Then I use my terminal to go into the websockify folder so I can see the run file. I issue it the command:
./run --web /path/to/noVNC --target-config /path/to/token.list localhost:6080
Finally, I open my web browser and go to :
http://localhost:6080/vnc_auto.html?path=?token=localhostnickname1
Where localhost1 is the nickname of my first server on the first line of token.list
This link was my reference. If you want to serve this outside of localhost -- change the parameter localhost:8060 from localhost to an IP
I am working on a Mac.
I am running Linux Ubuntu server in a VirtualBox. GlassFish 4 and MySql are already running there. The Linux IP is 10.0.1.12.
On the guest system (Mac) I am running Eclipse Luna. I installed the GlassFish Tools for Eclipse Luna and restarted Eclipse.
Then I wanted to add server for GlassFish4. But Eclipse is asking me for "Server root" and I have no clue what it means! I entered "10.0.1.12:4848/" just as I can access GlassFish from the host system (Mac OS) by a browser. But it just doesn't accept that URL. It seems to expect a local directory path. Here is the dialog box:
Thanks in advance for any hints!!
You need to install a Glassfish4 Server to your local machine (the one Eclipse is running on) despite the fact that you want to connect to and manage a remote Glassfish server; Eclipse will use some of the files in that local installation to manage the remote Glassfish server. Assuming you already have Glassfish4 installed on a remote machine:
[For example purposes]
Let's assume the remote Glassfish server is at 192.168.2.7 on default port 4848 for administration and you've set a password for 'admin' user as 'gfish'.
Let's also assume that your local desktop (development machine running Eclipse Luna) is at 192.168.2.3
Download Glassfish4 Open Source edition zip
Unzip the contents to a directory on your local machine: let's say inside of path /glassfish_server/ you will now have:
/glassfish_server/glassfish4/glassfish/ structure
Back in Eclipse:
Create a New Server -> Select 'Glassfish4' option
Server's Hostname =[remote ip address] // E.G. 192.168.2.7
Server Name: GlassFish 4 at 192.168.2.7 // get's auto-filled
[Next] This is the page you were specifically having issue with:
Set the Root Path to your Local Glassfish Server install directory
so in this example: /glassfish_server/glassfish4/glassfish/ should be accepted
[Next] Now use the credentials and configuration for your remote glassfish server. Run a Ping-Test to test connection.
The server root means the directory where GlassFish is located. This might be, for example, /opt/glassfish4/glassfish. Eclipse needs this so that it can look for the bin/ directory and be able to start/stop the server using the scripts in there.
I have taken a Angular App which works on Local host when I use visual studio IIE server.
I don't want to use Visual Studio and I am trying to test the app locally using XAMPP.
I am a complete beginner, and I cannot get the local host to pick-up the html initialization file. I have checked the following:
Skype is off and the port is set to 80 in XAMMP
the root server in HTTPd.conf is setup correctly (no slash at end)
I am getting a little confused as to 'how' angular will work on the XAMMP local host.
Do I need to get Yeoman or grunt (seen these apps in some posts, but they seem to be for command line environment).
Any help, or even a pointer to a step by step set-up would be great!
Angular is no different from a normal html web page, when it comes to working in a localhost.
Does your XAMPP work with standard HTML files?
Do you have any error generated?
OK. Got this sorted. I was over complicating things entirely, angular runs sweet on regular XAMPP, no Grunt/ Yeoman etc. required.
All you need to do is: 1. install XAMPP 2. Close Skype 3. Place you app, libraries and everything else in the folder C:\xampp\htdocs\
localhost/Angularappstartpage.html
BOOM!
it works.
You may need to adjust the port number on the localhost (default is 80 e.g. localhost:80/...)
You can also change the root folder in your XAMPP config setup to point to your local GIT.
Do this by changing the line in the HTTPD.conf file (click 'config' on the apache module)
DocumentRoot "C:/xampp/htdocs" to DocumentRoot "C:/myLocalGIT"
Hopefully this will help all the new guys out there. Good luck!
Skype blocks the port 80, which is used for browsing. XAMPP uses the same port so exactly.

If you use mysql, also open first XAMPP and start your services and then keep working on your SO as always.
RackSpace Cloud Server Ubuntu-12.04, Intellij Idea-11.1.2, Windows-8, Tomcat-7.0.26, JDK-6.
On Intellij Idea when i try to run jsf project on my remote Tomcat 7 server it says:
Error running servername: Unable to connect to the ip-address:1099
It seems problem is about JNDI port which is 1099 but I couldn't activate it I guess. Tomcat config is sth. like that:
What I've tried?
Setting CATALINA_OPTS or JAVA_OPTS on the server side with:
CATALINA_OPTS=-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=1099
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
and
JAVA_OPTS=-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=1099
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
But this one did not work, any ideas?
My answer to my question:
The correct way to deploy remotely is editing JAVA_OPTS environment variable on the remote server. Just enter the command below:
export JAVA_OPTS="-Dcom.sun.management.jmxremote=
-Dcom.sun.management.jmxremote.port=1099
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"
If that's not going to work and if you don't have any obsession to deploy your website via Intellij Idea, I've got the solution for this problem. To be able to run your website under Tomcat, you can/should get artifact in form of .war file.
It can be done in Intellij from project settings(ctrl+alt+shift+s) then hit the plus button and add new artifact(web:application archieve)
After rebuilding the artifact, .war file can be seen in project-folder\out\artifacts. Next, you should place this file into your tomcat/webapps folder.
For example if you are using Tomcat-7, the folder that I mean exists in /var/lib/tomcat7/webapps. Before copying your .war file you should rename it as ROOT.war. This provides to access your site directly by http://youripaddress:8080. After restarting Tomcat7 service you can access the site.
But not finished yet, you can debug your project remotely like you are debugging your project at your local machine with Intellij Idea. Open Run/Debug Configuration in Idea, hit the plus button and there must be Remote. This is the way to debug your projects for application servers like JBoss, Glassfish as well in Idea. Enter your host and port numbers, select your project as a module.
Before starting to debug, as Intellij says you should give the following parameter to your server JVM:
JAVA_OPTS="$JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005"
To be able to do that in Ubuntu and for Tomcat-7, modified the catalina.sh file in usr/share/tomcat7 folder. I inserted the parameter above of the if [ -z "$LOGGING_MANAGER" ]; then line. It must be on the middle part of the file. Then you should be able to debug your project with Intellij Idea.
