Why port 8080 is disapeared ?
We do not know that either. What do the Tomcat logs say ?
Is java or tomcat bind to port 8080?
Well, it depends on the point of view..
It is Tomcat which takes the decision, but since Tomcat runs under a
Java JVM, one could say that it is really Java which opens that port.
Compatible problem between JDK and Tomcat?
No.
Check the Tomcat configuration file : (TOMCAT_DIRECTORY)/conf/server.xml
In that file, there are several (uncommented) <Connector ...> tags.
Each such Connector corresponds to a port which Tomcat opens, and
listens on.
These ports can vary, depending on which platform you are on, which
Tomcat version, and your own configuration.
netstat -pan | grep LISTEN
will show you the open listening ports, and also the process-id/program
which "owns" that port.
ps -ef | grep (process-id) will show you if this is really Tomcat
If the port 8080 is there when you start Tomcat, and then disappears
after some time, the Tomcat logs should contain something about it.
A Connector does not just disappear by itself, so there must ne some
error happening.
In a standard Tomcat installation (from the Tomcat site
tomcat.apache.org), the logfiles would be in (TOMCAT_DIR)/logs.
In pre-packaged versions under Linux, they are usually under
/var/log/tomcatxxx/*,
but sometimes they are re-directed somewhere else.
Check the system script by which you are starting Tomcat to find out
where this is. (/etc/init.d/tomcatx.y probably)
