关于Ｔｏｍｃａｔ的配置问题，请各位赐教

[billbyf]

本人初学JSP，在C:\Program Files下安装Tomcat4.0后，设置如下环境变量：
JAVA_HOME：C:\j2sdk1.4.2
CATALINA_HOME：C:\Program Files\Apache Tomcat 4.0
CLASSPATH：C:\j2sdk1.4.2\lib
PATH：C:\j2sdk1.4.2\bin

运行start Tomcat ，出现如下提示：

Catalina.start: LifecycleException: null.open: java.net.BindException: Address
already in use: JVM_Bind

请问是怎么回事，如何解决？

看下JDK是否安装正确

[duan123]

你的端口被占用

[yupingping]

c:\jdk\lib\tools.jar;

[yupingping]

在tomcat目录下的conf目录下的server.xml中改一下端口
一般是查8080,然后改成如:8022
有时还要把8005和8009的也改一下

[xiaoya317]

楼上的已经说了~！改端口~！

[jishuo]

CLASSPATH是要配置　C:\j2sdk1.4.2\lib　下的JAR包　如c:\jdk\lib\tools.jar;
你要具体写清楚，你也可以改下TOMCAT的端口试试
