Server Will Not Start on Windows (Port Conflict)

If a message similar to the following is displayed when starting GlassFish Server on Microsoft Windows, a server port conflict has occurred:

Address already in use

This error occurs when another application is running on the GlassFish Server port (default 8080), or because a previous instance of GlassFish Server did not shut down cleanly.

You might also check the following:

• Is Another Application Running on the Server's Port?

• Has an Ungraceful Shutdown Occurred on a Previously Running Server?

Is Another Application Running on the Server's Port?

If another application is using the server's port, stop the other application, then restart GlassFish Server.

Has an Ungraceful Shutdown Occurred on a Previously Running Server?

Use the asadmin stop-domain command to stop the server, or explicitly kill the Java process and then restart GlassFish Server.
