解决java web项目导入后出现的问题 cannot be read or is not a valid ZIP file

http://www.cnblogs.com/haimingwey/archive/2012/07/17/2595473.html

今天导入以前的2个web项目后会出现以下2个错误：

1. Archive for required library: ‘WebContent/WEB-INF/lib/readme.txt’ in project ‘xxxxxxxxx’ cannot be read or is not a valid ZIP file

2. The project cannot be built until build path errors are resolved

问题解决，方法如下：

1. 用记事本打开项目根目录的.classpath文件，找到“<classpathentry kind=”lib” path=”WebContent/WEB-INF/lib/readme.txt”/>”这一行，删掉

2. 第一个问题解决后，此问题也会消失

JRE改成1.5

Error starting MyEclipse Tomcat server

点进去，选择jdk1.5
