今日在tomcat下开发，为避免在没有改变java方法和类名的情况下重新加载整个webapp，查阅了些资料后需要启用jvm的jpda， 同时要能远程debug；研究了半天发现其实很简单，人家已经做的很好了；只需要加jpda 4个字母就可以了；修改startup.bat 找到call "%EXECUTABLE%" start %CMD_LINE_ARGS% 改为call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS% 即可；这样在java的方法里面修改代码就不需要费时费力的重新加载上下文，也不需要重新登录。如果需要修改debug端口，（默认8000），改catalina.bat 中set JPDA_ADDRESS=8000 处；启动命令方式如下：echo Usage: catalina ( commands ... )echo commands:echo debug Start Catalina in a debuggerecho debug -security Debug Catalina with a security managerecho jpda start Start Catalina under JPDA debuggerecho run Start Catalina in the current windowecho run -security Start in the current window with security managerecho start Start Catalina in a separate windowecho start -security Start in a separate window with security managerecho stop Stop Catalinaecho version What version of tomcat are you running?
