我以前在 tomcat 5.5 中使用 jupload，效果很好！现在我的任务是将 tomcat 升级到版本 7（确切地说是 7.0.70），并发现 jupload 不再有效。我没有改变一点代码。唯一改变的是tomcat distr，（我什至在服务器xml上使用了相同的连接器定义）所以这是我的代码jsp页面

这是我的错误http://pastebin.com/xUaSjKdV的 jupload 日志
在我看来，在 jupload 开始准备上传后，由于某种原因它重定向到 Web 应用程序根目录（这反过来又被重定向到需要登录的网站的受保护区域）在这两种情况下，用户在进入 jsp 时已经登录页。.所以出于某种奇怪的原因，只是在登录页面中搜索成功字符串，当然不包含它，所以会弹出错误。我想知道为什么它首先重定向到网络应用程序根目录。我认为这可能与超时问题有关，将 asyncTimeout 的默认参数更改为“6000（根据文档，此参数在 5.5 版本中不存在）但仍然没有运气。这是我在 localhost 上的基本端口 8080 Connecto在tomcat上
<Connector acceptCount="100" protocol="org.apache.coyote.http11.Http11Protocol" connectionTimeout="20000" disableUploadTimeout="true" enableLookups="false" maxHttpHeaderSize="8192" maxSpareThreads="75" maxThreads="150" minSpareThreads="25" port="8080" redirectPort="8443"/>
有任何想法吗？
