1.有人认为是重复提交：
       工程在Tomcat6中运行正常，移到BEA Weblogic 10中如果访问其中的一个页面就出现Cannot parse POST parameters of request的异常。分析页面之后原来是因为页面中的js代码在初始化开始的时候请求了"doSth.action"，然后在js结束的地方又重新请求了一次"doSth.action"，这样会出现第一次的请求没有解析完，第二次请求又到了，这个时候http隧道被第二次占用了，导致第一次的请求非正常关闭，导致WebLogic服务器解析的第一次请求的参数无法读取请求结束符的错误："EOF after reading only: '0' of: '68' promised bytes, out of which at least: '0' were already buffered".
2.上一条中“第一次的请求没有解析完”提醒我，可能是由于上传内容过大而导致超时。在将上传的内容缩小后，就不再出现该问题了
3.很可能是上传的数据含有特殊字符


web防火墙导致的该问题
