How To Change Port Number Of GlassFish Server 4.1

Why to change port number?

Steps to change port number

1. First we need to find out the folder where GlassFish is installed
2. Select Services window by using Window -> Services in NetBeans IDE 8.0.2
3. Expand Servers node and select GlassFish Server 4.1
4. Right click and select Properties option from popup menu. You see the following window, which provides folders where GlassFish is installed and also port numbers related to it.
   
   You see HTTP Port is set to 8080. So we need to change that to some other non-conflicting port.
5. The directory of our interest is directory shown on the right of Domains Folder. In my system it is C:\Users\Srikanth Pragada\AppData\Roaming\NetBeans\8.0.2\config\GF_4.1
6. File domain.xml is where port number of GlassFish is stored. It is in present in domain1\config folder, which is in Domains Folder shown above. So, the full path in my system is C:\Users\Srikanth Pragada\AppData\Roaming\NetBeans\8.0.2\config\GF_4.1\domain1\config\domain.xml.
7. Start any text editor such as NotePad with Administrator privileges. For this, select editor, right click and select Run as administrator option to invoke editor with administrator privileges.
8. Open domain.xml file from the location mentioned in previous steps
9. Search for 8080 and change it to some other port number that doesn't conflict with other port numbers. I generally change it to 8888. See the lines in editor below.
   

10. Save domain.xml. If you start editor without adminstrator privileges, you get an error while saving. In this case, start editor using Run as administrator and redo editing.
11. Now go back to NetBeans and see the properties of GlassFish 4.1. It should be as shown below:
    

12. Go to GlassFish Server 4.1 in Servers node. Invoke popup menu and select Start option to start it. It should start without any issue.
