【Tomcat报错】错误:找不到或无法加载主类 org.apache.catalina.startup.Bootstrap

错误: 找不到或无法加载主类 org.apache.catalina.startup.Bootstrap

Application Server was not connected before run configuration stop, reason: java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is: java.net.SocketException: Connection reset]

报错原因：tomcat文件夹迁移，classpath配置了绝对路径

（tomcat9.0.27启动需要环境变量JAVA_HOME与CATALINA_HOME）

解决方案：重新配置 /bin/setclasspath.bat中的CATALINA_HOME

并使用相对路径：SET CATALINA_HOME=…/
