After installing Oracle XE, something in Oracle is listening on port 8080. I am not sure if they have an Apache HTTPD, a Tomcat, or something else. But how can I disable it?
It is Oracle XML DB HTTP Server; disable it as follows:
sqlplus '/ as sysdba'
EXEC DBMS_XDB.SETHTTPPORT(0);
commit;
You might have to restart Oracle XE (not just the listener).
