解决方法,推荐第三个
1、在Tomcat Launch Mode中,由Debug mode切换成 Run mode 。
2、在环境变量PATH前端添加jdk路径,如D:/Program Files/Java/jdk1.5.0_13/bin;然后重启机器。
3、打开eclipse,window>preferences>myeclipse>application server>tomcat 5 要选中Enable;然后后面tomcat home dircetory要选择你机器上tomcat的安装目录。
继续window>preferences>myeclipse>application server>tomcat>jdk 选择你机器上的jdk ,建议用add从新选择添加一个
