1.將項目部署到tomcat之外
通過Tomcat目錄下的
conf/Catalina/localhost/
新建projectname.xml的方式，可以將項目部署到tomcat的外部，該文件內容如下：
<?xml version="1.0" encoding="UTF-8"?>
<ContextdocBase="/Volumes/workspace/20130908/projectname/"
reloadable="true">
</Context>
2. 坑爹的web-app標籤屬性
檢查web.xml紅色部分, 避免類不被tomcat訪問
tomcat7能正常訪問classes
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0" metadata-complete="true">
