버젼별로 실행하기에는 의외로 간단하다..

Tomcat 5.0 과 Tomcat 4.0을 동시에 올릴경우

우선 Tomcat 5.0은 기본설정으로 하고

Tomcat 4.0은 confServer.xml 에서~
----------------------------------------------------------
[Server port="8006" shutdown="SHUTDOWN" debug="0"]
                             :
                             :
   [!-- Define a non-SSL HTTP/1.1 Connector on port 8080 --]
  [Connector className="org.apache.catalina.connector.http.HttpConnector"
          port="8082" minProcessors="5" maxProcessors="75"
          enableLookups="true" redirectPort="8443"
          acceptCount="10" debug="0" connectionTimeout="60000"/]
                             :
                             :
                             :
                             :
   [!-- Define an AJP 1.3 Connector on port 8009 --]
   [Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
          port="8010" minProcessors="5" maxProcessors="75"
          acceptCount="10" debug="0"/]
                             :
                             :
------------------------------------------------------------

세부분의 포트만 변경시켜주면 동시에 tomcat이 실행된다.
