Question

＆lt;％@ page import =“org.apache.commons.fileupload。*”％＆gt; //一些代码...... DiskFileUpload fu = new DiskFileUpload（）;

我正在尝试使用apache commons函数DiskFileUpload，但它有一个异常，因为无法找到fileupload.jar。我在这个论坛中查看与此类问题相关的其他回复，人们建议在WEB-INF / lib中添加该文件，我尝试但是它不适用于我。

也许我把它放在错误的位置？我的jsp路径是：apache-tomcat-6.0.29 / webapps / ROOT / ClockAdmin / upload.jsp WEB-INF是：apache-tomcat-6.0.29 / webapps / WEB-INF / commons-fileupload-1.2.2.jar LIB / 我看看其他帖子，但它仍然无效： Apache commons -> File Upload -> parseRequest() error

我得到以下例外：

Answer 1

您需要在/WEB-INF/lib文件夹中删除JAR，而不是/WEB-INF。

Answer 2

我不得不通过弹跳Tomcat服务器来手动部署WAR文件。这解压了WAR，当服务器重新启动时，它没有抛出任何异常。我只能想象我在Tomcat设置中的配置错误，以允许清单正确关闭并重新打开。
