Things to check for this error include the following:
If the console window is still open, the expected message is:
Domain domain Started
where domain is the name of the default domain. This indicates that the default domain was started successfully.
If the console window is already closed, check for messages in the log file:
If startup was successful, the expected message is similar to that on the console, and appears at the end of the log file:
[INFO][...][..][date&time][Application server startup complete .]
The server might be running at a different port number than expected, either because it was intentionally installed there, or because another server was already running on the default port when the server was installed.
Examine the server's configuration file:
Find the http-listener element.
Inspect the value of the port attribute.
Be sure to enter the correct port number when invoking the server.
A different port number was specified during installation.
A previous installation exists.
If the specified port number is already taken by another application when the server is started, the port number rolls forward to the next available number. For example, if a server is already running on the default 8080 port, the new Application Server instance uses port number 8081. If two servers are running, the port number rolls to 8082, and so on.
