JSF的Sun 1.2实现增加Apache tomahawk实现文件上传
JSF的Sun 1.2实现增加Apache tomahawk实现文件上传
(1)启动Myeclipse 6.5,创建新工程，增加JSF支持、Spring支持、Hibernate支持。
(2)把tomahawk需要的包tomahawk12-1.1.9.jar commons-fileupload-1.2.1.jar commons-io-1.4.jar commons-logging-1.0.4.jar
拷贝到工程的WebRootWEB-INFlib目录下
(3)配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
