Tomcat Port Modification

In borland\jbuilder2006\thirdparty\jakarta-tomcat-5.5.9\conf\ there is a server.xml file, preferably open with an editor, can also be opened with Notepad, found inside there are
<connector
port= "8080"
Maxhttpheadersize= "8192"
Maxthreads= "150"
Minsparethreads= "25"
maxsparethreads= "75"
Enablelookups= "false"
Redirectport= "8443"
acceptcount= "100"
connectiontimeout= "20000"
Disableuploadtimeout= "true"/>
Such a code, the port 8080 to the other port, restart Tomcat can be, the proposed change to 9000, this port no other programs occupy.
The ps:8080 port is typically occupied because the Oracle built-in HTTP service Tomcat takes up 8080 ports and can be stopped in service management
