本机上安装了jbuilder和tomcat．当启动一个web工程时，jbuilder自带的tomcat无法使用（８０８０端口）．要启动了自己另装的tomcat时，jbuilder自带的tomcat才能正常使用．这时jbuilder自带的tomcat占用８０８３端口,自己安装的tomcat占用８０８０端口．
就是说两个tomcat都要启动，我的web工程才能正常运行．否则会提示以下内容．D:\Borland\JBuilder2005\jdk1.4\bin\javaw -classpath "D:\Borland\JBuilder2005\thirdparty\jakarta-tomcat-5.0.27\bin\bootstrap.jar;D:\Borland\JBuilder2005\jdk1.4\lib\tools.jar" "-Dcatalina.home=D:/Borland/JBuilder2005/thirdparty/jakarta-tomcat-5.0.27" org.apache.catalina.startup.Bootstrap -config D:\Borland\untitled1\Tomcat\conf\server8080.xml start

自己装的tomcat启动后占用了8080端口，jb的tomcat就会用8083端口，这时一切正常，但是自装的tomcat关闭后，jb tomcat就会用8080端口，就无法正常使用了．
