GlassFish Server：管理员端口被空占用

Question

I tried to start glassfish server via the Netbeans IDE but it showed this error:

Could not start GlassFish Server: Administrator port is occupied by null
C:\Users\Ateeq Khaliq\Documents\NetBeansProjects\WebApplication1\nbproject\build-impl.xml:1045: Deployment error: Could not start GlassFish Server: Administrator port is occupied by null
See the server log for details.
BUILD FAILED (total time: 2 seconds)

I have changed the port also to 9999 in C:\\Users\\Ateeq Khaliq\\GlassFish_Server\\glassfish\\domains\\domain1\\config file.

How can I fix this?

Answer 2

netstat -aon | find ":4848" | find "LISTENING"

Kill the process that is using your Administrator port

Answer 3

如果您已经找到解决方案，它似乎是 Netbeans 中的一个错误，请告诉我。

Answer 4

I had the exact same problem and the way I solved it was to delete the glassfish, tomcat7 and tomcat 8 servers from my IDE. I then deleted their folders on my hard disk and reinstalled the glassfish alone. Everything worked fine after that.

Answer 5

If Netbeans is blocked by Firewall this happens. Make sure your Antivirus firewall is not blocking NetBeans. Grant NetBeans full access to act as a server (This is also asked when you start NetBeans).

Then you should be able to start your server through NetBeans

Answer 6

remove glassfish server from Netbeans and added another one click Tools-servers select your server and click remove servers and click add servers change the domain name and change port from 8080 to 8090 as you like. restart Netbeans

Answer 7
