Answer 1

没有关键代码，无法确定具体的错误原因;
java.net.SocketTimeoutException: Read timed out
产生这个错误，一般是大文件上传，web server超过。另外一个可能是的原因。以前看到过，如果action的path同即将跳转的jsp名字是一样，也会出现这个错误

Answer 2

java.net.SocketTimeoutException: Read timed out 
产生这个错误，一般是大文件上传，web server超时。 这个要修改web server的超时设置。另外一个可能是的原因。以前看到过，如果action的path同即将跳转的jsp名字是一样，也会出现这个错误，这个只要修改一个jsp的文件名就行了。

Answer 3

我的资源里有个struts1.2文件上传源码，包含检查大小、格式等功能。运行OK，楼主可以去看看

Answer 4

应该不是文件过大的问题，因为我上传的只是一张图片。action跟跳转的jsp页面一样，我查看了代码，没有这种问题。希望大家再仔细想想。专家呢？？？我可是冲着您来的！！！

Answer 5

你tomcat什么版本，低版本的tomcat有时也会出现这个问题！

Answer 6

tomcat5.0.那就是说是tomcat不够稳定的事了。您是这个意思么？？？

Answer 7

换个tomcat-5.5试试吧。5.0不知道。4.*是会出现你上面的情况。
